Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	1. Organization and Basis of Presentation Description of Business Sonendo, Inc. (“Sonendo” or the “Company”) was incorporated in June 2006 pursuant to the laws of the State of Delaware under the name Dentatek Corporation. In March 2011, the Company changed its name to Sonendo, Inc. The Company is a medical technology company that has developed and is commercializing the GentleWave System to treat tooth decay. The Company’s principal market is the United States. The Company’s products include the GentleWave System, which is cleared by the United States (“U.S.”) Food and Drug Administration (“FDA”) for sale in the U.S. and approved by Health Canada in Canada, along with the system’s sterilized, single-use procedure instruments ("PIs"). In addition, the Company offers practice management software to enable an integrated digital office for dental practitioners. Basis of Presentation The Company’s financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (“SEC”) on a consistent basis with the Company’s annual financial statements and in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, considered necessary for a fair statement of the Company’s financial information. Accordingly, the accompanying unaudited condensed consolidated financial statements do not include all of the information and notes required by GAAP for complete financial statements. The condensed consolidated balance sheet as of December 31, 2022 included herein was derived from the audited financial statements as of that date. The results of operations included in these condensed consolidated financial statements are not necessarily indicative of the results of operations to be expected for the year, any other interim period, or for any other future annual or interim period. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed, consolidated, or omitted. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 filed with the SEC on March 8, 2023. Liquidity On September 27, 2022, the Company completed a private placement (the "Private Placement"), issuing an aggregate of approximately 23.0 million shares of its common stock at a purchase price of $ 0.95 per share and pre-funded warrants to purchase an aggregate of 43.3 million shares of common stock at a purchase price of $ 0.949 per pre-funded warrant. The pre-funded warrants have an exercise price of $ 0.001 per share of common stock, are immediately exercisable and will remain exercisable until exercised in full. The aggregate net proceeds from the Private Placement, after deducting placement agent fees and other offering expenses, were $ 59.0 million. See Note 5, Stockholders' Equity, for additional information. As of March 31, 2023, the Company had cash and cash equivalents and short-term investments of $ 74.9 million . The Company has a limited operating history, and the revenue and income potential of the Company’s business and market are unproven. The Company has experienced net losses and negative cash flows from operations since its inception and as of March 31, 2023 had an accumulated deficit of $ 384.5 million . During the three months ended March 31, 2023, the Company incurred net losses of $ 15.4 million and used $ 17.0 million of cash and cash equivalents in operations. In April 2023, the Company has received approximately $ 3.2 million payment of the total $ 4.4 million related to Employee Retention Credit ("ERC") recognized in other income in 2022. The Company will continue to incur significant costs and expenses related to its ongoing operations until it gains market acceptance of its products and achieves a level of revenues adequate to support its operations. The accompanying unaudited condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The unaudited condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty. Based on its current operating plan, the Company expects that its existing cash and cash equivalents and short-term investments will be sufficient to fund its operating expenses and capital expenditure requirements for at least 12 months from the date of issuance of the accompanying unaudited condensed consolidated financial statements. The Company plans to fund its operations, capital funding and other liquidity needs, using existing cash, cash equivalents and short-term investments and, to the extent available, cash generated from commercial operations. If the Company's actual operating expenses significantly exceed its operating plan or its debt financing arrangements become unavailable because certain borrowing requirements are not met (see Note 9), the Company may have to significantly delay or scale back its operations to reduce working capital requirements. In addition, the Company would prioritize necessary and appropriate steps to enable the continued operations of the business and preservation of the value of its assets beyond the next 12 months, including but not limited to, actions such as reducing personnel-related costs and delaying or curtailing the Company’s commercial efforts, development activities and other discretionary expenditures that are within the Company’s control. These reductions in expenditures, if required, may have an adverse impact on the Company’s ability to achieve certain of its planned objectives. On March 10, 2023, the California Department of Financial Protection and Innovation shut down Silicon Valley Bank (SVB) due to liquidity concerns and appointed the Federal Deposit Insurance Corporation (FDIC) as receiver. On Sunday, March 12, 2023, the U.S. Treasury Department, Federal Reserve and FDIC announced that all bank depositors would have access to their money starting Monday, March 13, 2023. On March, 27, 2023, SVB began operating as a division of First Citizens Bank. As of March 31, 2023, the Company held approximately $ 0.6 million in operating accounts at SVB. The Company’s remaining cash and cash equivalents and short-term investments, consisting of money market funds, high-grade corporate securities, and U.S. government backed securities, reside in custodial accounts held by U.S. Bank. There has been no disruption to the Company's operations. Effects of the Macroeconomic Environment and COVID-19 The Company’s unaudited condensed consolidated financial statements as of and for the three months ended March 31, 2023 reflect the Company’s estimates of the impact of the macroeconomic environment, including the impact of inflation, higher interest rates, and the COVID-19 pandemic. The duration and the scope of these conditions cannot be predicted; therefore, the extent to which these conditions will directly or indirectly impact the Company’s business, results of operations and financial condition, is uncertain. The Company is not aware of any specific event or circumstance that would require an update to its estimates, judgments and assumptions or a revision of the carrying value of the Company’s assets or liabilities as of the date of this filing. The COVID-19 pandemic negatively impacted the Company's operations, revenue and overall financial condition, and may negatively impact its operations, revenue, and overall financial condition in the future if new and more transmissible vaccine-resistant variants emerge. The Company's customers, including endodontists, have experienced significant financial hardship and some of them may never fully recover. The Company has also experienced disruptions, and may experience future disruptions, including: delays in capital and clinical sales representatives becoming fully trained and productive; difficulties and delays in dental practitioner outreach and training dental practitioners to use its GentleWave System; travel restrictions; delays in initiation, enrollment and follow-ups of its clinical studies; challenges with maintaining adequate supply from third-party manufacturers of components and finished goods and distribution providers; and access to dental practitioners for training and case support. The Company expects that any future restrictions on dental procedures, as a result of COVID-19 or the emergence of any vaccine resistant variant or other pandemic, epidemic or infectious disease outbreak, and other related issues including supply chain disruptions, would have a negative impact on its operations, revenue and overall financial condition. Operating Segments The Company has business activity and operates two operating and reportable segments: Product and Software. Operating segments are defined as components of an enterprise for which discrete financial information is available and evaluated regularly by the chief operating decision maker, who is the Company’s chief executive officer (“CEO”), for the purpose of allocating resources and evaluating performance. Emerging Growth Company Status The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to avail itself of this exemption and, therefore, for new or revised accounting standards applicable to public companies, the Company will be subject to an extended transition period until those standards would otherwise apply to private companies.

Accounting Policies [Abstract]
Summary Accounting Policies and Recent Accounting Pronouncements	2. Summary Accounting Policies and Recent Accounting Pronouncements The accounting policies followed by the Company are set forth in Part II, Item 8, Note 2, Summary of Accounting Policies , of the Notes to Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2022. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make informed estimates, judgements and assumptions that affect the reported amounts in the unaudited condensed consolidated financial statements and disclosures in the accompanying notes, including estimates of probable losses and expenses, as of the date of the accompanying unaudited condensed consolidated financial statements. Management considers many factors in selecting appropriate financial accounting policies and in developing the estimates and assumptions that are used in the preparation of these unaudited condensed consolidated financial statements. Management must apply significant judgment in this process. In addition, other factors may affect estimates, including the expected business and operational changes, the sensitivity and volatility associated with the assumptions used in developing estimates, and whether historical trends are expected to be representative of future trends. The estimation process often may yield a range of potentially reasonable estimates of the ultimate future outcomes, and management must select an amount that falls within that range of reasonable estimates. Actual results could differ materially from the estimates and assumptions used in the preparation of the accompanying unaudited condensed consolidated financial statements under different assumptions or conditions. Revenue Recognition Contracts with Customers The Company recognizes revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods and services. Specifically, the Company applies the following five core principles to recognize revenue: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, the Company satisfies a performance obligation. Product revenue is generated from sales of the GentleWave Console and related PIs and accessories. Software revenue is generated from sales of TDO's endodontist practice management software licenses. The Company’s products are sold primarily in the United States and Canada directly to customers through its field sales force. Performance Obligations The Company’s performance obligations primarily arise from the manufacture and delivery of the GentleWave System, related PIs and accessories, and the delivery or license of TDO software and related ancillary services. Payment terms are typically on open credit terms consistent with industry practice and do not have significant financing components. Consideration may be variable based on volume. The Company considers the individual deliverables in its product offering as separate performance obligations and assesses whether each promised good or service is distinct. The total contract transaction price is determined based on the consideration expected to be received, based on the stated value in contractual arrangements or the estimated cash to be collected in no-contracted arrangements, and is allocated to the identified performance obligations based upon the relative standalone selling prices of the performance obligations. The stand-alone selling price is based on an observable price offered to other comparable customers. The Company estimates the standalone selling price using the market assessment approach considering market conditions and entity-specific factors including, but not limited to, features and functionality of the products and services, geographies, type of customer and market conditions. The Company regularly reviews and updates standalone selling prices as necessary. The consideration the Company receives in exchange for its goods or services is only recognized when it is probable that a significant reversal will not occur. The consideration to which the Company expects to be entitled includes a stated list price, less various forms of variable consideration. The Company estimates related variable consideration at the point of sale, including discounts, product returns, refunds, and other similar obligations. Revenue is recognized over time when the customer simultaneously receives and consumes the benefits provided by the Company’s performance. Revenue is recognized at a point in time if the criteria for recognizing revenue over time are not met, and the Company has transferred control of the goods to the customer. Product revenue is recognized at a point in time when the Company has transferred control to the customer, which is generally when title of the goods transfers to the customer. Software is licensed via delivery to the customer or via a service arrangement under which cloud-based access is provided on a subscription basis (software-as-a-service). When a fixed up-front license fee is received in exchange for the delivery of software, revenue is recognized at the point in time when the delivery of the software has occurred. When software is licensed on a subscription basis, revenue is recognized over the respective license period. The Company also sells extended service contracts on its GentleWave Systems. Sales of extended service contracts are recorded as deferred revenue until such time as the standard warranty expires, which is generally up to two years from the date of sale. Service contract revenue is recognized on a straight-line basis over time consistent with the life of the related service contract in proportion to the costs incurred in fulfilling performance obligations under the service contract. Revenue for technical support and other services is recognized ratably over the performance obligation period. The Company generally does not experience returns. If necessary, a provision is recorded for estimated sales returns and allowances and is deducted from gross product revenue to arrive at net product revenue in the period the related revenue is recorded. These estimates are based on historical sales returns and allowances and other known factors. Actual returns and claims in any future period are inherently uncertain and thus may differ from these estimates. If actual or expected future returns and claims are significantly greater or lower than the reserves established, a reduction or increase to revenue will be recorded in the period in which such a determination is made. All non-income government-assessed taxes (sales and use taxes) collected from the Company’s customers and remitted to governmental agencies are recorded in accrued expenses until they are remitted to the government agency. The Company has adopted the practical expedient permitting the direct expensing of costs incurred to obtain contracts where the amortization of such costs would occur over one year or less, and it applied to substantially all the Company’s contracts. Contract liabilities The Company recognizes a contract liability when a customer pays for goods or services for which the Company has not yet transferred control. The balances of the Company’s contract liabilities are as follows: March 31, December 31, 2023 2022 (in thousands) Extended service contracts $ 319 $ 336 Subscription software licenses 403 481 Total contract liabilities 722 817 Less: long-term portion 140 — Contract liabilities – current $ 582 $ 817 Contract liabilities are included within other current liabilities and other long-term liabilities in the accompanying unaudited condensed consolidated balance sheets. Revenue recognized during the three months ended March 31, 2023 and 2022 that was included in the contract liability balance as of December 31, 2022 and 2021 was $ 0.4 million in each year. Disaggregation of revenue The Company disaggregates revenue from contracts with customers by segment and by the timing of when goods and services are transferred, which depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected. The following table provides information regarding revenues disaggregated by segment and the timing of when goods and services are transferred: Three Months Ended March 31, 2023 2022 (in thousands) Product revenue recognized at a point in time $ 8,524 $ 7,027 Product revenue recognized over time 154 176 Software revenue recognized at a point in time 449 219 Software revenue recognized over time 1,597 1,611 Total $ 10,724 $ 9,033 No individual customer accounted for more than 10% of sales for the three months ended March 31, 2023 and 2022. Warranty Reserve The Company provides a standard warranty on its GentleWave Systems for a specified period of time. For the three months ended March 31, 2023 and 2022, GentleWave Systems sold were covered by the warranty for a period of up to two years from the date of sale. Estimated warranty costs are recorded as a liability at the time of delivery with a corresponding provision to cost of sales. Warranty accruals are estimated based on the current product costs, the Company’s historical experience, management’s expectations of future conditions and standard maintenance schedules. The Company evaluates this reserve on a regular basis and makes adjustments as necessary. The following table provides a reconciliation of the change in estimated warranty liabilities for the three months ended March 31, 2023 and 2022: Three Months Ended March 31, 2023 2022 (in thousands) Balance at beginning of period $ 1,930 $ 1,620 Provision for warranties issued 195 310 Warranty costs incurred ( 368 ) ( 315 ) Balance at end of period $ 1,757 $ 1,615 Current portion $ 1,335 $ 1,153 Non-current portion 422 462 Total $ 1,757 $ 1,615 The warranty liability, current and non-current, are included in other current liabilities and other liabilities, respectively, on the unaudited condensed consolidated balance sheets. Recent Accounti ng Pronouncements Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of accounting standards updates (“ASU”). ASUs not listed below were assessed and determined not to be applicable or are expected to have minimal impact on the Company’s unaudited condensed consolidated financial statements. Accounting Pronouncement Recently Adopted In October 2021, the FASB, issued Accounting Standards Update No. 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires an entity (acquirer) to recognize and measure contract assets and liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers. This update is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years, with early adoption permitted. The amendments should be applied prospectively to business combinations occurring on or after the effective date of the amendments. The Company early adopted the ASU on January 1, 2023 . The adoption did no t have an impact on the Company's unaudited condensed consolidated financial statements. The Company will evaluate the impact for each business combination transaction completed hereafter.

Fair Value of Financial Instrum

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	4. Fair Value of Financial Instruments The Company applies fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The Company’s financial instruments consist principally of cash, cash equivalents, short-term investments, accounts receivable, accounts payable, operating lease liabilities, warrant liabilities and a term loan. Fair value is measured as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market. Valuation techniques that are consistent with the market, income or cost approach are used to measure fair value. The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three levels: Level 1 – Observable inputs such as unadjusted quoted prices in active markets that are accessible at the measurement date for identical unrestricted assets or liabilities the Company has the ability to access. Level 2 – Inputs (other than quoted prices included within Level 1) that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. Level 3 – Unobservable inputs that are significant to the fair value measurement and reflect the reporting entity’s use of significant management judgment and assumptions when there is little or no market data. Level 3 assets and liabilities include those whose fair value measurements are determined using pricing models, discounted cash flow methodologies or similar valuation techniques and significant management judgment or estimation. These include the Black-Scholes option-pricing model which uses inputs such as expected volatility, risk-free interest rate and expected term to determine fair market valuation. Assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurements. The Company reviews the fair value hierarchy classification at each reporting date. Changes in the ability to observe valuation inputs may result in a reclassification of levels for certain assets or liabilities within the fair value hierarchy. The Company did not have any transfers of assets and liabilities between the levels of the fair value measurement hierarchy during the periods presented. The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable, and certain accrued expenses approximate fair value due to the short-term nature of these items. Accordingly, the Company estimates that the recorded amounts approximate fair market value. The following table provides the assets and liabilities measured at fair value on a recurring basis and indicate the fair value hierarchy of the valuation techniques utilized by the Company to determine such value at March 31, 2023 and December 31, 2022: March 31, 2023 Fair Value Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs (in thousands) Assets: Cash equivalents: Money market funds $ 12,098 $ 12,098 $ — $ — Total cash equivalents at fair value 12,098 12,098 — — Short-term investments: U.S. treasury securities 28,257 28,257 — — Commercial paper and corporate bonds 29,602 — 29,602 — U.S. government agency bonds 4,440 — 4,440 — Total short-term investments at fair value 62,299 28,257 34,042 — Total assets at fair value $ 74,397 $ 40,355 $ 34,042 $ — March 31, 2023 Fair Cost Amounts Recognized in Accumulated Other Comprehensive Loss Unrealized Gains Unrealized Losses (in thousands) Available-for-sale securities: U.S. treasury securities $ 28,257 $ 28,265 $ 10 $ ( 18 ) Commercial paper and corporate bonds 29,602 29,610 — ( 8 ) U.S. government agency bonds 4,440 4,430 11 — Total available-for-sale securities at fair value $ 62,299 $ 62,305 $ 21 $ ( 26 ) December 31, 2022 Fair Value Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs (in thousands) Assets: Cash equivalents: Money market funds $ 12,253 $ 12,253 $ — $ — Commercial paper 1,998 — 1,998 — U.S. government agency bonds 1,991 — 1,991 — Total cash equivalents at fair value 16,242 12,253 3,989 — Short-term investments: U.S. treasury securities 33,622 33,622 — — Commercial paper and corporate bonds 40,162 — 40,162 — Total short-term investments at fair value 73,784 33,622 40,162 — Total assets at fair value $ 90,026 $ 45,875 $ 44,151 $ — December 31, 2022 Fair Cost Amounts Recognized in Accumulated Other Comprehensive Loss Unrealized Gains Unrealized Losses (in thousands) Available-for-sale securities: U.S. treasury securities $ 33,622 $ 33,676 $ — $ ( 54 ) Commercial paper and corporate bonds 40,162 40,169 — ( 7 ) Total available-for-sale securities at fair value $ 73,784 $ 73,845 $ — $ ( 61 ) Money market funds and U.S. Treasury securities are highly liquid investments and are actively traded. The pricing information on these investment instruments is readily available and can be independently validated as of the measurement date. This approach results in the classification of these securities as Level 1 of the fair value hierarchy. Commercial paper, U.S. government agency bonds and corporate bonds are measured at fair value using Level 2 inputs. The Company reviews trading activity and pricing for these investments as of each measurement date. When sufficient quoted pricing for identical securities is not available, the Company uses market pricing and other observable market inputs for similar securities obtained from third party data providers. These inputs represent quoted prices for similar assets in active markets or these inputs have been derived from observable market data. This approach results in the classification of these securities as Level 2 of the fair value hierarchy.

Equity [Abstract]
Stockholders' Equity	5. Stockholders’ Equity Warrants In April 2022, the Company amended its term loan and the warrants previously issued to Perceptive Credit Holdings III, LP (“Perceptive”) and certain of its affiliates to purchase an aggregate of 304,105 shares of its common stock. Such warrants were amended solely to reduce the exercise price of the warrants to $ 12.00 per share. Warrants issued and outstanding at March 31, 2023 and December 31, 2022 included 27,397 warrants with exercise price of $ 10.95 per share and 304,106 warrants with exercise price of $ 12.00 per share in each period. These warrants expire between December 2023 and August 2031 . On September 27, 2022, the Company completed the Private Placement, issuing an aggregate of approximately 23.0 million shares of its common stock at a purchase price of $ 0.95 per share and pre-funded warrants to purchase an aggregate of 43.3 million shares of common stock at a purchase price of $ 0.949 per pre-funded warrant to certain institutional investors and accredited investors (the "Purchasers"). The pre-funded warrants have an exercise price of $ 0.001 per share of common stock, are immediately exercisable and will remain exercisable until exercised in full. The aggregate net proceeds from the Private Placement, after deducting placement agent fees and other offering expenses, were $ 59.0 million. The pre-funded warrants include a provision whereby the exercisability of the warrants may be limited if, upon exercise, the warrant holder or any of its affiliates would beneficially own more than 9.99 % of the Company's common stock. The threshold is subject to the Purchaser's rights under the pre-funded warrant to increase or decrease such percentage to any other percentage not in excess of 19.99 % upon at least 61 days' prior notice from the Purchaser to the Company. As of March 31, 2023, approximately 1.1 million shares have been issued pursuant to the exercise of pre-funded warrants and 42.2 million shares underlying the pre-funded warrants remain outstanding. The pre-funded warrants are classified as equity and are accounted for as a component of additional paid-in capital at the time of issuance. The pre-funded warrants are included in the calculation of basic and diluted loss per share. Pursuant to the terms and conditions of the purchase agreements entered into by the Purchasers, the Company was obligated to file a registration statement with the SEC registering the resale by the Purchasers of the shares of common stock issued to them in the Private Placement and the shares of common stock to be issued to them upon exercise of the pre-funded warrants issued to them in the Private Placement within 45 days of the closing of the Private Placement. On November 4, 2022, the Company filed a registration statement on Form S-3 (File No. 333-268174), as required under the purchase agreements, and the registration statement was declared effective by the SEC on November 16, 2022.

Leases [Abstract]
Leases	7. Leases The Company leases office space under operating leases with expirations ranging from March 2025 to December 2026, some of which include rent escalations or an option to extend the lease for up to three years per renewal. The exercise of lease renewal options is at the sole discretion of the Company. As of March 31, 2023 , the Company has not entered into any leases that have not yet commenced that would entitle the Company to significant rights or create additional obligations. The Company determines whether a contract is or contains a lease at the inception of the contract. A contract will be deemed to be or contain a lease if the contract conveys the right to control and direct the use of identified property, plant, or equipment for a period of time in exchange for consideration. The Company generally must also have the right to obtain substantially all of the economic benefits from the use of the property, plant, and equipment. The Company has elected the practical expedient to not separate its lease component from non-lease component for its real estate leases. The Company has elected the practical expedient not to apply the lease recognition requirements to short-term leases with an initial term of 12 months or less. The Company uses either its incremental borrowing rate or the implicit rate in the lease agreement as the basis to calculate the present value of future lease payments at lease commencement. The incremental borrowing rate represents the rate the Company would have to pay to borrow funds on a collateralized basis over a similar term and in a similar economic environment. Future minimum lease payments under these leases are as follows: Lease Amounts (in thousands) 2023 (remaining nine months) $ 999 2024 1,555 2025 1,010 2026 645 Total future minimum lease payments 4,209 Less: Imputed Interest ( 493 ) Present value of operating lease liabilities $ 3,716 Less: Current portion 1,246 Long-term operating lease liabilities $ 2,470 Weighted average remaining lease term in years 2.99 Weighted average discount rate 8.79 % Variable operating lease expenses consist primarily of real estate taxes and insurance.

Commitments and Contingencies	8. Commitments and Contingencies Contingencies The Company is subject to claims and assessments from time to time in the ordinary course of business, including without limitation, actions with respect to intellectual property, employment, regulatory, product liability and contractual matters. In connection with these proceedings or matters, the Company regularly assesses the probability and amount (or range) of possible issues based on the developments in these proceedings or matters. A liability is recorded in the accompanying unaudited condensed consolidated financial statements if it is determined that it is probable that a loss has been incurred, and that the amount (or range) of the loss can be reasonably estimated. The Company’s management does not believe that any such matters, individually or in the aggregate, will have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows.

Term Loan	9. Term Loan Perceptive loan On April 6, 2022, the Company entered into Amendment No. 1 (the “First Amendment”) to the Amended and Restated Credit Agreement and Guaranty with Perceptive (the “Perceptive Loan Agreement”). The First Amendment extended the borrowing deadline for the first tranche of $ 10.0 million of delayed-draw term loans from December 31, 2021 to September 30, 2022 , subject to the Company having generated at least $ 36.0 million in revenue for the 12 consecutive month period most recently ended prior to the borrowing date. The First Amendment also extended the borrowing deadline for the second tranche of $ 10.0 million delayed-draw term loans from March 31, 2022 to June 30, 2023 , subject to (i) the Company having generated at least $ 46.0 million in revenue for the 12 consecutive month period most recently ended prior to the borrowing date; and (ii) the closing market capitalization of the Company being at least $ 100.0 million on each trading day of the period of 15 consecutive trading days ending on the business day the borrowing notice for the tranche is delivered to Perceptive. The Company borrowed the first tranche of $ 10.0 million on July 29, 2022 and received net proceeds of $ 9.9 million. As a condition to entering into the First Amendment, on April 6, 2022, the Company also amended the warrants previously issued to Perceptive and certain of its affiliates to purchase an aggregate of 304,105 shares of its common stock. Such warrants were amended solely to reduce the exercise price of the warrants to $ 12.00 per share. In August 2022, a portion of these warrants representing 153,421 shares were transferred to a third party and its affiliates. For the three months ended March 31, 2023 and 2 022, the interest rate for amounts borrowed under the Perceptive Loan Agreement, as amended, was the greater of the one-month LIBOR and 2.00 % plus the applicable margin of 9.25 %. On January 13, 2023, the Company entered into Amendment No. 2 (the "Second Amendment") to the Perceptive Loan Agreement to replace the existing benchmark rate from the one-month LIBOR with a one-month Secured Overnight Financing Rate ("SOFR"). All other terms remain unchanged on the original agreement. For the three months ended March 31, 2023 and 2022 , the effective interest rate of the Perceptive loan was 16.71 % and 14.59 %, respectively. As of March 31, 2023 and 2022, the fair value of the Perceptive loan approximates its carrying amount. Future principal repayments on the Perceptive loan as of March 31, 2023 , are as follows: Principal (in thousands) 2026 $ 40,000 Total $ 40,000 The Perceptive Loan Agreement, as amended, includes financial covenants that require the Company to (i) maintain, at all times, a minimum aggregate balance of $ 3.0 million in cash in one or more controlled accounts, and (ii) satisfy certain minimum revenue thresholds, measured for the 12 consecutive month period on each calendar quarter-end until June 30, 2026. These thresholds increase over time and range from $ 26.4 million for the twelve-month period ended September 30, 2021 to $ 95.3 million for the twelve month period ended June 30, 2026. Failure to satisfy these financial covenants would constitute an event of default under the agreement. For the three months ended March 31, 2023 , the Company was in compliance with all financial covenants and conditions required by the outstanding Perceptive Loan Agreement, as amended .

Income Tax Disclosure [Abstract]
Income Taxes	10. Income Taxes The Company maintains a full valuation allowance against its net deferred tax assets as of March 31, 2023 based on the current assessment that it is not more likely than not these future benefits will be realized before expiration. No material income tax expense or benefit has been recorded given the valuation allowance position and projected taxable losses in the jurisdictions where the Company files income tax returns. The Company has not experienced any significant increases or decreases to its unrecognized tax benefits since December 31, 2022 and does not expect any within the next 12 months. The Company monitors changes to the tax laws in the states it conducts business and files corporate income tax returns. Utilization of the net operating loss carryforwards may be subject to substantial annual limitation due to ownership change limitations that may have occurred or that could occur in the future, as required by Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), as well as similar state provisions. These ownership changes may limit the amount of net operating loss carryforwards that can be utilized annually to offset future taxable income and tax, respectively. In general, an “ownership change,” as defined by Section 382 of the Code, results from a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50 percentage points of the outstanding stock of a company by certain stockholders or public groups. The Company has not completed an analysis regarding the limitation of net operating loss and R&D credit carryforwards as of March 31, 2023. The Company is subject to U.S. federal and various states income taxes. The federal returns for tax y ears 2020 through 2022 remain open to examination and the state returns remain subject to examination for tax years 2019 through 2022 . Carryforward attributes that were generated in years where the statute of limitations is closed may still be adjusted upon examination by the Internal Revenue Service or other respective tax authorities. All other state jurisdictions remain open to examination.

Segment Reporting [Abstract]
Segment Information	11. Segment Information The Company operates and reports its results in two business segments, Product and Software. The Company reports segment information based on the management approach. The management approach designates the internal reporting used by the Company's chief operating decision maker ("CODM") for decision making and performance assessment as the basis for determining the Company’s reportable segments. The performance measures of the Company’s reportable segments are primarily income (loss) from operations. Income (loss) from operations for each segment includes all revenues, related cost of net revenues, gross margin and operating expenses directly attributable to the segment. The Company’s Product segment includes sales of the Company's GentleWave System console and related accessories and instruments. The Company’s Software segment includes sales of the Company's traditional software licenses for practice management software to enable an integrated digital office for endodontists. The following tables present the Company’s segment information for the three months ended March 31 : 2023 2022 (in thousands, except percentage data) Product Software Total Product Software Total Revenue $ 8,678 $ 2,046 $ 10,724 $ 7,203 $ 1,830 $ 9,033 Cost of sales 6,700 678 7,378 6,078 676 6,754 Gross profit 1,978 1,368 3,346 1,125 1,154 2,279 Gross margin 23 % 67 % 31 % 16 % 63 % 25 % Operating expenses: Selling, general and administrative 14,114 552 14,666 11,526 459 11,985 Research and development 2,927 567 3,494 4,431 419 4,850 Total operating expenses 17,041 1,119 18,160 15,957 878 16,835 Income (loss) from operations $ ( 15,063 ) $ 249 $ ( 14,814 ) $ ( 14,832 ) $ 276 $ ( 14,556 ) Segment Assets: As of March 31, 2023 As of December 31, 2022 (in thousands) Product $ 112,473 $ 125,713 Software 11,439 11,572 Total $ 123,912 $ 137,285

Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make informed estimates, judgements and assumptions that affect the reported amounts in the unaudited condensed consolidated financial statements and disclosures in the accompanying notes, including estimates of probable losses and expenses, as of the date of the accompanying unaudited condensed consolidated financial statements. Management considers many factors in selecting appropriate financial accounting policies and in developing the estimates and assumptions that are used in the preparation of these unaudited condensed consolidated financial statements. Management must apply significant judgment in this process. In addition, other factors may affect estimates, including the expected business and operational changes, the sensitivity and volatility associated with the assumptions used in developing estimates, and whether historical trends are expected to be representative of future trends. The estimation process often may yield a range of potentially reasonable estimates of the ultimate future outcomes, and management must select an amount that falls within that range of reasonable estimates. Actual results could differ materially from the estimates and assumptions used in the preparation of the accompanying unaudited condensed consolidated financial statements under different assumptions or conditions.
Revenue Recognition	Revenue Recognition Contracts with Customers The Company recognizes revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods and services. Specifically, the Company applies the following five core principles to recognize revenue: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, the Company satisfies a performance obligation. Product revenue is generated from sales of the GentleWave Console and related PIs and accessories. Software revenue is generated from sales of TDO's endodontist practice management software licenses. The Company’s products are sold primarily in the United States and Canada directly to customers through its field sales force. Performance Obligations The Company’s performance obligations primarily arise from the manufacture and delivery of the GentleWave System, related PIs and accessories, and the delivery or license of TDO software and related ancillary services. Payment terms are typically on open credit terms consistent with industry practice and do not have significant financing components. Consideration may be variable based on volume. The Company considers the individual deliverables in its product offering as separate performance obligations and assesses whether each promised good or service is distinct. The total contract transaction price is determined based on the consideration expected to be received, based on the stated value in contractual arrangements or the estimated cash to be collected in no-contracted arrangements, and is allocated to the identified performance obligations based upon the relative standalone selling prices of the performance obligations. The stand-alone selling price is based on an observable price offered to other comparable customers. The Company estimates the standalone selling price using the market assessment approach considering market conditions and entity-specific factors including, but not limited to, features and functionality of the products and services, geographies, type of customer and market conditions. The Company regularly reviews and updates standalone selling prices as necessary. The consideration the Company receives in exchange for its goods or services is only recognized when it is probable that a significant reversal will not occur. The consideration to which the Company expects to be entitled includes a stated list price, less various forms of variable consideration. The Company estimates related variable consideration at the point of sale, including discounts, product returns, refunds, and other similar obligations. Revenue is recognized over time when the customer simultaneously receives and consumes the benefits provided by the Company’s performance. Revenue is recognized at a point in time if the criteria for recognizing revenue over time are not met, and the Company has transferred control of the goods to the customer. Product revenue is recognized at a point in time when the Company has transferred control to the customer, which is generally when title of the goods transfers to the customer. Software is licensed via delivery to the customer or via a service arrangement under which cloud-based access is provided on a subscription basis (software-as-a-service). When a fixed up-front license fee is received in exchange for the delivery of software, revenue is recognized at the point in time when the delivery of the software has occurred. When software is licensed on a subscription basis, revenue is recognized over the respective license period. The Company also sells extended service contracts on its GentleWave Systems. Sales of extended service contracts are recorded as deferred revenue until such time as the standard warranty expires, which is generally up to two years from the date of sale. Service contract revenue is recognized on a straight-line basis over time consistent with the life of the related service contract in proportion to the costs incurred in fulfilling performance obligations under the service contract. Revenue for technical support and other services is recognized ratably over the performance obligation period. The Company generally does not experience returns. If necessary, a provision is recorded for estimated sales returns and allowances and is deducted from gross product revenue to arrive at net product revenue in the period the related revenue is recorded. These estimates are based on historical sales returns and allowances and other known factors. Actual returns and claims in any future period are inherently uncertain and thus may differ from these estimates. If actual or expected future returns and claims are significantly greater or lower than the reserves established, a reduction or increase to revenue will be recorded in the period in which such a determination is made. All non-income government-assessed taxes (sales and use taxes) collected from the Company’s customers and remitted to governmental agencies are recorded in accrued expenses until they are remitted to the government agency. The Company has adopted the practical expedient permitting the direct expensing of costs incurred to obtain contracts where the amortization of such costs would occur over one year or less, and it applied to substantially all the Company’s contracts. Contract liabilities The Company recognizes a contract liability when a customer pays for goods or services for which the Company has not yet transferred control. The balances of the Company’s contract liabilities are as follows: March 31, December 31, 2023 2022 (in thousands) Extended service contracts $ 319 $ 336 Subscription software licenses 403 481 Total contract liabilities 722 817 Less: long-term portion 140 — Contract liabilities – current $ 582 $ 817 Contract liabilities are included within other current liabilities and other long-term liabilities in the accompanying unaudited condensed consolidated balance sheets. Revenue recognized during the three months ended March 31, 2023 and 2022 that was included in the contract liability balance as of December 31, 2022 and 2021 was $ 0.4 million in each year. Disaggregation of revenue The Company disaggregates revenue from contracts with customers by segment and by the timing of when goods and services are transferred, which depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected. The following table provides information regarding revenues disaggregated by segment and the timing of when goods and services are transferred: Three Months Ended March 31, 2023 2022 (in thousands) Product revenue recognized at a point in time $ 8,524 $ 7,027 Product revenue recognized over time 154 176 Software revenue recognized at a point in time 449 219 Software revenue recognized over time 1,597 1,611 Total $ 10,724 $ 9,033 No individual customer accounted for more than 10% of sales for the three months ended March 31, 2023 and 2022.
Warranty Reserve	Warranty Reserve The Company provides a standard warranty on its GentleWave Systems for a specified period of time. For the three months ended March 31, 2023 and 2022, GentleWave Systems sold were covered by the warranty for a period of up to two years from the date of sale. Estimated warranty costs are recorded as a liability at the time of delivery with a corresponding provision to cost of sales. Warranty accruals are estimated based on the current product costs, the Company’s historical experience, management’s expectations of future conditions and standard maintenance schedules. The Company evaluates this reserve on a regular basis and makes adjustments as necessary. The following table provides a reconciliation of the change in estimated warranty liabilities for the three months ended March 31, 2023 and 2022: Three Months Ended March 31, 2023 2022 (in thousands) Balance at beginning of period $ 1,930 $ 1,620 Provision for warranties issued 195 310 Warranty costs incurred ( 368 ) ( 315 ) Balance at end of period $ 1,757 $ 1,615 Current portion $ 1,335 $ 1,153 Non-current portion 422 462 Total $ 1,757 $ 1,615 The warranty liability, current and non-current, are included in other current liabilities and other liabilities, respectively, on the unaudited condensed consolidated balance sheets.
