Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) and the rules of the U.S. Securities and Exchange Commission (“SEC”). The year-end consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by US GAAP. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair statement of the results for interim periods have been included. Results for interim periods should not be considered indicative of results for a full year. These financial statements and related notes contain the accounts of DENTSPLY SIRONA Inc. and Subsidiaries (“Dentsply Sirona” or the “Company”) on a consolidated basis and should be read in conjunction with the consolidated financial statements and notes included in the Company’s most recent Form 10-K for the year ended December 31, 2018. The accounting policies of the Company, as applied in the interim consolidated financial statements presented herein are substantially the same as presented in the Company’s Form 10-K for the year ended December 31, 2018, except as may be indicated below. Revenue Recognition At March 31, 2019, the Company had $28.7 million of deferred revenue recorded in Accrued liabilities in the Consolidated Balance Sheets. The Company expects to recognize significantly all of the deferred revenue within the next twelve months. Accounts and Notes Receivable The Company records a provision for doubtful accounts, which is included in Selling, general and administrative expenses in the Consolidated Statements of Operations. Accounts and notes receivables – trade, net are stated net of allowances for doubtful accounts and trade discounts, which were $32.5 million at March 31, 2019 and $24.5 million at December 31, 2018. Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) with subsequent amendments (collectively, “Topic 842”). The Company adopted the new leasing standards on January 1, 2019 using the modified retrospective approach transition method. Results for reporting periods beginning after January 1, 2019 are presented under ASC 842, while prior periods are not adjusted and continue to be reported in accordance with historic accounting under ASC 840. The Company elected the package of practical expedients permitted under the transition guidance within the standard, which eliminates the reassessment of past leases, classification and initial direct costs. The Company did not elect to adopt the hindsight practical expedient. The Company recognized material right-of-use assets and liabilities in the Consolidated Balance Sheets for its operating lease commitments with terms greater than twelve months. See Note 8, Leases for additional information. The impact of adopting this standard, by financial statement line item, on January 1, 2019 was as follows: (in millions) Balance at Assets Operating lease right-of-use assets, net 167.1 Property, plant, and equipment, net 1.8 Liabilities Accrued liabilities $ 39.4 Notes payable and current portion of long-term debt 0.2 Long-term debt 1.5 Operating lease liabilities 126.5 In August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging.” This newly issued accounting standard improves the financial reporting and disclosure of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. The amendments in this update make improvements to simplify the application of the hedge accounting guidance in current US GAAP based on the feedback received from preparers, auditors, users and other stakeholders. More specifically, this update expands and refines hedge accounting for both nonfinancial and financial risk components and aligns the recognition and presentation of the effects of the hedging instruments and the hedged items in the financial statements. The effect of adoption should be reflected as of the beginning of the fiscal year of adoption. For cash flow and net investment hedges existing at the date of adoption, an entity should apply a cumulative-effect adjustment related to eliminating the separate measurement of ineffectiveness to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the beginning of the fiscal year that an entity adopts the amendments in this update. The amended presentation and disclosure guidance is required only prospectively. The Company adopted this accounting standard during the quarter ended March 31, 2019. The adoption of this standard did not materially impact the statements of operations, financial position, cash flows and disclosures. Recently Issued Accounting Pronouncements Not Yet Adopted In August 2018, the FASB issued ASU No. 2018-14 "Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans." This newly issued accounting standard changes disclosure requirements for defined benefit plans, including removal and modification of existing disclosures. The amendments in this standard are required for fiscal years ending after December 15, 2020. Early adoption is permitted. The amendments should be applied on a retrospective basis for all periods presented. The Company is currently assessing the impact that this standard will have on its financial position, results of operations, cash flows and disclosures.

SEGMENT INFORMATION

SEGMENT INFORMATION	3 Months Ended
	Mar. 31, 2019
Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION The Company has numerous operating businesses covering a wide range of dental consumable products, dental technology and dental equipment products primarily serving the professional dental market, and certain healthcare products. Professional dental products represented approximately 92% of net sales for all periods presented. The operating businesses are combined into two operating groups, which generally have overlapping geographical presence, customer bases, distribution channels, and regulatory oversight. These operating groups are considered the Company’s reportable segments as the Company’s chief operating decision-maker regularly reviews financial results at the operating group level and uses this information to manage the Company’s operations. The accounting policies of the segments are consistent with those described in the Company’s most recently filed Form 10-K, in the summary of significant accounting policies. The Company evaluates performance of the segments based on the groups’ net third party sales, excluding precious metal content, and segment adjusted operating income. Net third party sales excluding precious metal content is considered a measure not calculated in accordance with US GAAP, and is therefore considered a non-US GAAP measure. Management believes that the presentation of net sales, excluding precious metal content, provides useful information to investors because a portion of Dentsply Sirona’s net sales is comprised of sales of precious metals generated through sales of the Company’s precious metal dental alloy products, which are used by third parties to construct crown and bridge materials. Due to the fluctuations of precious metal prices and because the cost of the precious metal content of the Company’s sales is largely passed through to customers and has minimal effect on earnings, Dentsply Sirona reports net sales both with and without precious metal content to show the Company’s performance independent of precious metal price volatility and to enhance comparability of performance between periods. The Company uses its cost of precious metal purchased as a proxy for the precious metal content of sales, as the precious metal content of sales is not separately tracked and invoiced to customers. The Company believes that it is reasonable to use the cost of precious metal content purchased in this manner since precious metal dental alloy sale prices are typically adjusted when the prices of underlying precious metals change. The Company’s exclusion of precious metal content in the measurement of net third party sales enhances comparability of performance between periods as it excludes the fluctuating market prices of the precious metal content. The Company also evaluates segment performance based on each segment’s adjusted operating income before provision for income taxes and interest. Segment adjusted operating income is defined as operating income before income taxes and before certain corporate headquarter unallocated costs, restructuring and other costs, interest expense, interest income, other expense (income), net, amortization of intangible assets and depreciation resulting from the fair value step-up of property, plant and equipment from acquisitions. The Company’s segment adjusted operating income is considered a non-US GAAP measure. A description of the products and services provided within each of the Company’s two operating segments is provided below. During the three months ended March 31, 2019, certain reclassifications have been made to prior year’s data in order to conform to current year presentation. Specifically, during the three months ended March 31, 2019, the Company's laboratory dental business moved into the Consumables segment as the products sold from this business are typically made on a recurring basis and have similar sales and operating characteristics as the other businesses in this segment. The Company moved the orthodontics business into the Technologies & Equipment segment to take advantage of the synergies related to digital planning and treatment within this segment. The Company also moved the instruments business into the Technologies & Equipment segment in order to take advantage of the synergies that stem from pairing equipment with instruments, which are often sold in conjunction with each other. The segment information reflects the revised structure for all periods shown. Technologies & Equipment This segment is responsible for the worldwide design, manufacture, sales and distribution of the Company’s Dental Technology and Equipment Products and Healthcare Consumable Products. These products include dental implants, CAD/CAM systems, orthodontic dental products, imaging systems, treatment centers, instruments as well as consumable medical device products. Consumables This segment is responsible for the worldwide design, manufacture, sales and distribution of the Company’s Dental Consumable Products which include preventive, restorative, endodontic and laboratory dental products.

INVENTORIES	INVENTORIES Inventories are stated at the lower of cost and net realizable value. The cost of inventories determined by the last-in, first-out (“LIFO”) method at March 31, 2019 and December 31, 2018 was $9.6 million and $9.0 million, respectively. The cost of remaining inventories was determined by the first-in, first-out (“FIFO”) or average cost methods. If the FIFO method had been used to determine the cost of LIFO inventories, the amounts at which net inventories are stated would be higher than reported at March 31, 2019 and December 31, 2018 by $11.2 million and $10.2 million, respectively. Inventories, net of inventory valuation reserves, consist of the following: (in millions) March 31, 2019 December 31, 2018 Finished goods $ 392.5 $ 380.0 Work-in-process 88.5 89.2 Raw materials and supplies 137.2 129.7 Inventories, net $ 618.2 $ 598.9

LEASES

Leases [Abstract]
Leases	LEASES The Company leases real estate, automobiles and equipment under various operating and finance leases. Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the implicit rate is not readily determinable in most of the Company’s lease agreements, the Company uses its estimated secured incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Lease expense is recognized on a straight-line basis over the lease term. Leases with an initial term of 12 months or less are not recorded on the balance sheet; the Company recognizes lease expense for these leases on a straight-line basis over the lease term. Beginning January 1, 2019, any new real estate and equipment operating lease agreements with lease and nonlease components, will be accounted for as a single lease component. The Company determines if an arrangement is a lease or contains a lease at inception. The Company’s leases have remaining lease terms of approximately 1 year to 11 years. Many of the Company's real estate and equipment leases have one or more options to renew, with terms that can extend from 1 to 3 years or more, which are not included in the initial lease term. The Company does not have lease agreements with residual value guarantees, sale-and-leaseback terms or material restrictive covenants. The Company does not have any sublease arrangements. The net present value of finance and operating lease assets and liabilities were as follows: (in millions, except percentages) Location in the Consolidated Balance Sheets March 31, 2019 Assets Current assets Finance leases Property, plant and equipment, net $ 1.7 Operating leases Operating lease right-of-use assets, net 163.9 Total right-of-use assets $ 165.6 Liabilities Current liabilities Finance leases Notes payable and current portion of long-term debt $ 0.3 Operating leases Accrued liabilities 41.9 Noncurrent liabilities Finance leases Long-term debt 1.5 Operating leases Operating lease liability 125.5 Total lease liabilities $ 169.2 Supplemental information: Weighted-average discount rate Finance leases 3.3 % Operating leases 3.1 % Weighted-average remaining lease term in years Finance leases 7.3 Operating leases 5.8 The lease cost recognized in the Consolidated Statements of Operations for the three months ended were as follows: (in millions) March 31, 2019 Finance lease cost Amortization of right-of-use assets $ 0.1 Operating lease cost 13.2 Short-term lease cost 0.1 Variable lease cost 1.9 Total lease cost $ 15.3 The contractual maturity dates of the remaining lease liabilities at March 31, 2019 were as follows: (in millions) Finance Leases Operating Leases Total 2019, excluding the three months ended March 31, 2019 $ 0.2 $ 34.9 $ 35.1 2020 0.3 38.7 39.0 2021 0.3 29.2 29.5 2022 0.3 20.7 21.0 2023 0.2 15.3 15.5 2024 and beyond 0.8 45.4 46.2 Total lease payments $ 2.1 $ 184.2 $ 186.3 Less imputed interest 0.3 16.8 17.1 Present value of lease liabilities $ 1.8 $ 167.4 $ 169.2 The contractual maturity dates presented under prior lease accounting guidance of the remaining rental commitments at December 31, 2018 were as follows: (in millions) Finance Leases Operating Leases Total 2019 $ 4.2 $ 36.6 $ 40.8 2020 4.2 28.5 32.7 2021 2.5 22.1 24.6 2022 1.8 16.4 18.2 2023 1.3 12.7 14.0 2024 and beyond 1.1 16.9 18.0 Total lease payments $ 15.1 $ 133.2 $ 148.3 The supplemental cash flow information for the three months ended were as follows: (in millions) March 31, 2019 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 12.6 Financing cash flows from finance leases 0.1 Right-of-use assets obtained in exchange for new lease liabilities: Operating leases $ 4.3

FINANCIAL INSTRUMENTS AND DERIV

FINANCIAL INSTRUMENTS AND DERIVATIVES	3 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
FINANCIAL INSTRUMENTS AND DERIVATIVES	FINANCIAL INSTRUMENTS AND DERIVATIVES Derivative Instruments and Hedging Activities The Company’s activities expose it to a variety of market risks, which primarily include the risks related to the effects of changes in foreign currency exchange rates and interest rates. These financial exposures are monitored and managed by the Company as part of its overall risk management program. The objective of this risk management program is to reduce the volatility that these market risks may have on the Company’s operating results and equity. The Company employs derivative financial instruments to hedge certain anticipated transactions, firm commitments, or assets and liabilities denominated in foreign currencies. Additionally, the Company utilizes interest rate swaps to convert variable rate debt to fixed rate debt. Derivative Instruments Designated as Hedging Cash Flow Hedges The following summarizes the notional amounts of cash flow hedges by derivative instrument type at March 31, 2019 and the notional amounts expected to mature during the next 12 months, with a discussion of the various cash flow hedges by derivative instrument type following the table: (in millions) Aggregate Notional Amount Aggregate Notional Amount Maturing within 12 Foreign exchange forward contracts $ 369.4 $ 279.1 Interest rate swaps 263.3 113.3 Total derivative instruments designated as cash flow hedges $ 632.7 $ 392.4 Foreign Exchange Risk Management The Company uses a layered hedging program to hedge select anticipated foreign currency cash flows to reduce volatility in both cash flows and reported earnings of the consolidated Company. The Company accounts for the designated foreign exchange forward contracts as cash flow hedges. As a result, the Company records the fair value of the contracts primarily through AOCI based on the assessed effectiveness of the foreign exchange forward contracts. The Company measures the effectiveness of cash flow hedges of anticipated transactions on a spot-to-spot basis rather than on a forward-to-forward basis. Accordingly, the spot-to-spot change in the derivative fair value will be deferred in AOCI and released and recorded in the Consolidated Statements of Operations in the same period that the hedged transaction is recorded. The time value component of the fair value of the derivative is reported on a straight line basis in Cost of products sold in the Consolidated Statements of Operations in the period which it is applicable. Any cash flows associated with these instruments are included in operating activities in the Consolidated Statements of Cash Flows. The Company hedges various currencies, with the most significant activity occurring in euros, Swedish kronor, Canadian dollars, British pounds, Swiss francs and Australian dollars. Interest Rate Risk Management The Company uses interest rate swaps to convert a portion of its variable interest rate debt to fixed interest rate debt. At March 31, 2019, the Company has one significant exposure hedged with interest rate contracts. The exposure is hedged with derivative contracts having notional amounts totaling 12.6 billion Japanese yen, which effectively converts the underlying variable interest rate debt facility to a fixed interest rate of 0.9% for an initial term of five The Company enters into interest rate swap contracts infrequently as they are only used to manage interest rate risk on long-term debt instruments and not for speculative purposes. Any cash flows associated with these instruments are included in operating activities in the Consolidated Statements of Cash Flows. Cash Flow Hedge Activity Gains (losses) recorded in AOCI in the Consolidated Balance Sheets and Cost of products sold in the Company’s Consolidated Statements of Operations related to all cash flow hedges for the three months ended March 31, 2019 and 2018 were insignificant. For the rollforward of derivative instruments designated as cash flow hedges in AOCI see Note 3, Comprehensive Income. Hedges of Net Investments in Foreign Operations The Company has significant investments in foreign subsidiaries the most significant of which are denominated in euros, Swiss francs, Japanese yen and Swedish kronor. The net assets of these subsidiaries are exposed to volatility in currency exchange rates. The Company employs both derivative and non-derivative financial instruments to hedge a portion of this exposure. The derivative instruments consist of foreign exchange forward contracts and cross currency basis swaps. The non-derivative instruments consist of foreign currency denominated debt held at the parent company level. Translation gains and losses related to the net assets of the foreign subsidiaries are offset by gains and losses in derivative and non-derivative financial instruments designated as hedges of net investments, which are included in AOCI. Any cash flows associated with these instruments are included in investing activities in the Consolidated Statements of Cash Flows except for derivative instruments that include an other-than-insignificant financing element, for which all cash flows are classified as financing activities in the Consolidated Statements of Cash Flows. During the three months ended March 31, 2019, the Company early terminated its existing 245.6 million euro cross currency basis swap and entered into a new 263.4 million euro cross currency basis swap maturing in August 2021. The cross currency basis swap is designated as a hedge of net investments. This contract effectively converts the $295.7 million bond coupon from 4.1% to 1.2%, which will result in a net reduction of interest expense through maturity in 2021. The early termination resulted in a cash receipt of $17.4 million. The following summarizes the notional amount of hedges of net investments by derivative instrument at March 31, 2019 and the notional amounts expected to mature during the next 12 months: (in millions) Aggregate Aggregate Notional Amount Maturing within 12 Months Foreign exchange forward contracts $ 765.5 $ 255.2 Cross currency basis swaps 295.5 — Total for instruments not designated as hedges $ 1,061.0 $ 255.2 The following summarizes the amount of gains (losses) recorded in AOCI in the Consolidated Balance Sheets and Other expense (income), net in the Company's Consolidated Statements of Operations related to the hedges of net investments for the three months ended March 31, 2019 and 2018: March 31, 2019 Gain in AOCI Consolidated Statements of Operations Location Recognized in Income (Expense) (in millions) Effective Portion: Cross currency basis swaps $ 3.1 Interest expense $ 2.0 Foreign exchange forward contracts 15.5 Other expense (income), net 3.5 Total for net investment hedging $ 18.6 $ 5.5 March 31, 2018 Loss in AOCI Consolidated Statements of Operations Location Recognized in Income (Expense) (in millions) Effective Portion: Cross currency basis swaps $ (6.4) Interest expense $ 1.7 Other expense (income), net (6.6) Foreign exchange forward contracts (11.5) Other expense (income), net 1.5 Total for net investment hedging $ (17.9) $ (3.4) Derivative Instruments Not Designated as Hedges The Company enters into derivative instruments with the intent to partially mitigate the foreign exchange revaluation risk associated with recorded assets and liabilities that are denominated in a non-functional currency. The gains and losses on these derivative transactions offset the gains and losses generated by the revaluation of the underlying non-functional currency balances and are recorded in Other expense (income), net in the Consolidated Statements of Operations. The Company primarily uses foreign exchange forward contracts to hedge these risks. Any cash flows associated with the foreign exchange forward contracts and interest rate swaps not designated as hedges are included in cash from operating activities in the Consolidated Statements of Cash Flows. The following summarizes the aggregate notional amounts of the Company’s economic hedges not designated as hedges by derivative instrument types at March 31, 2019 and the notional amounts expected to mature during the next 12 months: Aggregate Aggregate Notional Amount Maturing within 12 Months Notional (in millions) Amount Foreign exchange forward contracts $ 410.9 $ 270.4 Total for instruments not designated as hedges $ 410.9 $ 270.4 Gains (losses) recorded in the Company’s Consolidated Statements of Operations related to the economic hedges not designated as hedging for the three months ended March 31, 2019 and 2018 were insignificant. Balance Sheet Offsetting Substantially all of the Company’s derivative contracts are subject to netting arrangements, whereby the right to offset occurs in the event of default or termination in accordance with the terms of the arrangements with the counterparty. While these contracts contain the enforceable right to offset through netting arrangements with the same counterparty, the Company elects to present them on a gross basis in the Consolidated Balance Sheets. Offsetting of financial liabilities under netting arrangements at March 31, 2019 were insignificant. Offsetting of financial assets under netting arrangements at March 31, 2019 were as follows: Gross Amounts Not Offset in the Consolidated Balance Sheets (in millions) Gross Amounts Recognized Gross Amount Offset in the Consolidated Balance Sheets Net Amounts Presented in the Consolidated Balance Sheets Financial Instruments Cash Collateral Received/Pledged Net Amount Assets Foreign exchange forward contracts $ 45.2 $ — $ 45.2 $ (8.1) $ — $ 37.1 Cross currency basis swaps 1.0 — 1.0 (0.4) — 0.6 Total Assets $ 46.2 $ — $ 46.2 $ (8.5) $ — $ 37.7 Offsetting of financial liabilities under netting arrangements at December 31, 2018 were insignificant. Offsetting of financial assets under netting arrangements at December 31, 2018 were as follows: Gross Amounts Not Offset in the Consolidated Balance Sheets (in millions) Gross Amounts Recognized Gross Amount Offset in the Consolidated Balance Sheets Net Amounts Presented in the Consolidated Balance Sheets Financial Instruments Cash Collateral Received/Pledged Net Amount Assets Foreign exchange forward contracts $ 33.7 $ — $ 33.7 $ (1.8) $ — $ 31.9 Cross currency basis swaps 11.6 — 11.6 (1.6) — 10.0 Total Assets $ 45.3 $ — $ 45.3 $ (3.4) $ — $ 41.9

FAIR VALUE MEASUREMENT

FAIR VALUE MEASUREMENT	3 Months Ended
	Mar. 31, 2019
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT	FAIR VALUE MEASUREMENT The Company records financial instruments at fair value with unrealized gains and losses related to certain financial instruments reflected in AOCI in the Consolidated Balance Sheets. In addition, the Company recognizes certain liabilities at fair value. The Company applies the market approach for recurring fair value measurements. Accordingly, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities that are recorded at fair value as of the balance sheet date are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The fair value of financial instruments is determined by reference to various market data and other valuation techniques as appropriate. The Company believes the carrying amounts of cash and cash equivalents, accounts receivable (net of allowance for doubtful accounts), prepaid expenses and other current assets, accounts payable, accrued liabilities, income taxes payable and notes payable approximate fair value due to the short-term nature of these instruments. The Company estimated the fair value using Level 1 inputs and carrying value of total long-term debt, including the current portion, was $1,569.7 million and $1,565.8 million, respectively at March 31, 2019. At December 31, 2018, the Company estimated the fair value and carrying value of total long-term debt, including the current portion, was $1,577.1 million and $1,575.5 million, respectively. The variable interest rate on the Japanese yen term loan is consistent with current market conditions, therefore the fair value approximates the loan’s carrying value. The following set forth by level within the fair value hierarchy the Company’s financial assets that were accounted for at fair value on a recurring basis at March 31, 2019 and both assets and liabilities at December 31, 2018: March 31, 2019 (in millions) Total Level 1 Level 2 Level 3 Assets Cross currency basis swaps $ 1.0 $ — $ 1.0 $ — Foreign exchange forward contracts 46.0 — 46.0 — Total assets $ 47.0 $ — $ 47.0 $ — Liabilities Interest rate swaps $ 3.5 $ — $ 3.5 $ — Foreign exchange forward contracts 5.8 — 5.8 — Contingent considerations on acquisitions 9.1 — — 9.1 Total liabilities $ 18.4 $ — $ 9.3 $ 9.1 December 31, 2018 (in millions) Total Level 1 Level 2 Level 3 Assets Cross currency basis swaps $ 11.6 $ — $ 11.6 $ — Foreign exchange forward contracts 33.7 — 33.7 — Total assets $ 45.3 $ — $ 45.3 $ — Liabilities Interest rate swaps $ 0.2 $ — $ 0.2 $ — Foreign exchange forward contracts 3.2 — 3.2 — Contingent considerations on acquisitions 9.1 — — 9.1 Total liabilities $ 12.5 $ — $ 3.4 $ 9.1 There have been no transfers between levels during the three months ended March 31, 2019.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Uncertainties in Income Taxes The Company recognizes in the interim consolidated financial statements, the impact of a tax position, if that position is more likely than not of being sustained on audit, based on the technical merits of the position. It is reasonably possible that certain amounts of unrecognized tax benefits will significantly increase or decrease within 12 months of the reporting date of the Company’s interim consolidated financial statements. Final settlement and resolution of outstanding tax matters in various jurisdictions during the next twelve months are not expected to be significant. Other Tax Matters During the three months ended March 31, 2019, the Company recorded $2.4 million of tax expense for discrete tax matters. The Company also recorded a $1.5 million tax benefit related to the indefinite-lived intangible asset impairment charge recorded during the quarter.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Litigation The SEC’s Division of Enforcement has asked the Company to provide documents and information concerning the Company’s accounting and disclosures. The Company is cooperating with the SEC’s investigation. The Company is unable to predict the ultimate outcome of this matter, or whether it will have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows. On January 11, 2018, Tom Redlich, a former employee, filed a lawsuit against the Company, demanding supplemental compensation pursuant to an agreement allegedly entered into with Sirona Dental GmbH which was intended to entice Mr. Redlich to continue to work for the company for no less than eight years following the date of this agreement. The Company filed its response on April 4, 2018, denying the authenticity and enforceability of, and all liability under, the alleged agreement. The court held an initial hearing on the matter on April 11, 2018. Mr. Redlich filed his reply on July 9, 2018. The Company filed its response to that reply on August 23, 2018, refuting the allegations in Mr. Redlich’s reply and continuing to deny liability under the alleged agreement. Following that, Mr. Jost Fischer, upon invitation of the Company, joined the litigation against Mr. Redlich as a third party. The court held a hearing on August 30, 2018 where the parties outlined their respective legal positions. In late November 2018, Mr. Fischer filed a statement to the court in which he disputed the central allegations raised by Mr. Redlich in his lawsuit and his supplemental submissions to the court. Based on Mr. Fischer’s statement, the Company filed a further written statement to the court, therein insisting on its previous legal position and presenting new factual submissions and evidence. In response, Mr. Redlich filed a written statement rejecting the positions of Mr. Fischer and the Company. In late January 2019 the court held hearings in which Mr. Redlich and a number of witnesses provided oral testimony to the court. In early April 2019, the court held a hearing, receiving additional testimony and the court plans to conduct a further hearing in the matter on May 29, 2019. The Company continues to defend against this claim vigorously. On January 25, 2018, Futuredontics, Inc. received service of a purported class action lawsuit brought by Henry Olivares and other similarly situated individuals in the Superior Court of the State of California for the County of Los Angeles. In January 2019, an amended complaint was filed adding another named plaintiff, Rachael Clarke, and various claims. The plaintiff class alleges several violations of the California wage and hours laws, including, but not limited to, failure to provide rest and meal breaks and the failure to pay overtime. The parties have engaged in written and other discovery. On February 5, 2019, Plaintiff Calethia Holt (represented by the same counsel as Mr. Olivares and Ms. Clarke) filed a separate representative action in Los Angeles Superior Court alleging a single violation of the Private Attorneys’ General Act that is based on the same underlying claims as the Olivares/Clarke lawsuit. The Company has not yet been served in connection with this action. On April 5, 2019, Plaintiff Kendra Cato filed a similar action in Los Angeles Superior Court alleging a single violation of the Private Attorneys’ General Act that is based on the same underlying claims as the Olivares/Clarke lawsuit. The Company has been served with the Cato complaint. The Company continues to vigorously defend against these matters. On June 7, 2018, and August 9, 2018, John Castronovo and Irving Golombeck, respectively, filed substantially identical putative class action suits in the Supreme Court of the State of New York, County of New York claiming that the Company, certain of its present and former officers and directors, and former officers and directors of Sirona violated U.S. securities laws (together, the "State Court Class Action"). The plaintiffs allege that the registration statement/joint proxy statement filed with the SEC on December 4, 2015 (the "Registration Statement") in connection with the Merger contained material misrepresentations and omitted required information by failing to disclose, among other things, that a distributor had allegedly purchased excessive inventory of legacy Sirona products and that three distributors of the Company's and Sirona's products and equipment had allegedly been engaging in anticompetitive conduct. The plaintiffs assert these claims on behalf of a putative class of former shareholders of Sirona who exchanged their shares of Sirona stock for shares of the Company's stock in the Merger. On September 19, 2018, the Court consolidated the two actions. On October 9, 2018, defendants filed a motion to stay discovery pending determination of their motion to dismiss. Plaintiffs filed an amended complaint on November 2, 2018 and defendants moved to dismiss the amended complaint on December 17, 2018. Oral argument on the motion to stay discovery took place on January 2, 2019. Plaintiffs filed their opposition to the motion to dismiss on January 31, 2019, and defendants' reply in further support was filed on March 1, 2019. On December 19, 2018, Boynton Beach Employees' Pension Plan filed a putative class action in the U.S. District Court for the Eastern District of New York, alleging that the Company, certain of its present and former officers and directors, and former officers and directors of Sirona violated U.S. securities laws (the "Federal Class Action"). The plaintiff alleges the same claims as those asserted in the State Court Class Action, relating to the alleged material misrepresentations and omissions of required information in the Registration Statement. In addition, the plaintiff alleges that the defendants made false and misleading statements in quarterly and annual reports and other public statements between February 20, 2014, and August 7, 2018. The plaintiff asserts claims on behalf of a putative class consisting of (a) all purchasers of the Company's stock during the period February 20, 2014 through August 7, 2018, (b) former shareholders of Sirona who exchanged their shares of Sirona stock for shares of the Company's stock in the Merger, and (c) holders of the Company's shares who held shares as of the record date of December 2, 2015 and were entitled to vote with respect to the Merger. Motions for appointment of lead plaintiff and lead counsel were filed on February 19, 2019. On April 29, 2019, John Behrmann and Nancy Behrmann, purported stockholders of the Company, filed a derivative action on behalf of the Company in the District of Delaware against the Company's Directors. Specifically, Plaintiffs allege that the Directors breached their fiduciary duties by causing the Company to improperly misrepresent the business prospects of the Company, including regarding the existence of an alleged antitrust scheme between the Company and three of its distributors. Plaintiffs also claim that the Directors' misconduct has subjected the Company to multiple securities class actions and other litigation. Based on the same set of factual allegations, Plaintiffs assert additional claims against the directors for unjust enrichment, gross mismanagement, waste of corporate assets, and violations of sections 10(b) and 14(a) of the Exchange Action and SEC Rules 10b-5 and 14a-9. Plaintiffs are seeking monetary damages and various corporate governance reforms. On January 25, 2019, defendants moved to stay all proceedings in the State Court Class Action pending final disposition of the Federal Class Action and on March 27, 2019, the court held a hearing on the motion to stay and the motion to dismiss. The Company intends to defend itself vigorously in these actions. As a result of an audit by the IRS for fiscal years 2012 through 2013, on February 11, 2019, the IRS issued to the Company a “30-day letter” and a Revenue Agent’s Report (“RAR”), relating to the Company’s worthless stock deduction in 2013 in the amount of $546.0 million. The RAR disallows the deduction and, after adjusting the Company’s net operating loss carryforward, asserts that the Company is entitled to a refund of $4.7 million for 2012, has no tax liability for 2013, and owes a deficiency of $17.1 million in tax for 2014, excluding interest. In accordance with ASC 740, the Company recorded the tax benefit associated with the worthless stock deduction in the Company’s 2012 financial statements. The Company will submit a formal protest disputing on multiple grounds the proposed taxes. The Company believes the IRS position is without merit and believes that it is more likely-than-not that the Company’s position will be sustained upon further review. The Company has not accrued a liability relating to the proposed tax adjustments. However, the outcome of this dispute involves a number of uncertainties, including those inherent in the valuation of various assets at the time of the worthless stock deduction, and those relating to the application of the Internal Revenue Code and other federal income tax authorities and judicial precedent. Accordingly, there can be no assurance that the dispute with the IRS will be resolved favorably. If determined adversely, the dispute would result in a current period charge to earnings and could have a material adverse effect in the consolidated results of operations, financial position and liquidity of the Company. The Swedish Tax Agency has disallowed certain of the Company’s interest expense deductions for the tax years from 2013 to 2017 and is also expected to do the same for the 2018 tax year. If such interest expense deductions were disallowed, the Company would be subject to an additional $41.0 million in tax expense. The Company has appealed the disallowance to the Swedish administrative court. With respect to such deductions taken in the tax years from 2013 to 2014, the court ruled against the Company on July 5, 2017. On August 7, 2017, the Company appealed the unfavorable decision of the Swedish administrative court. On November 5, 2018, the Company delivered its final argument to the administrative court of appeal at a hearing. The European Union Commission has taken the view that Sweden’s interest deduction limitation rules are incompatible with European Union law and supporting legal opinions, and therefore the Company has not paid the tax or made provision in its financial statements for such potential expense. The Company intends to vigorously defend its position and pursue related appeals. In addition to the matters disclosed above, the Company is, from time to time, subject to a variety of litigation and similar proceedings incidental to its business. These legal matters primarily involve claims for damages arising out of the use of the Company’s products and services and claims relating to intellectual property matters including patent infringement, employment matters, tax matters, commercial disputes, competition and sales and trading practices, personal injury and insurance coverage. The Company may also become subject to lawsuits as a result of past or future acquisitions or as a result of liabilities retained from, or representations, warranties or indemnities provided in connection with, divested businesses. Some of these lawsuits may include claims for punitive and consequential, as well as compensatory damages. Based upon the Company’s experience, current information and applicable law, it does not believe that these proceedings and claims will have a material adverse effect on its consolidated results of operations, financial position or liquidity. However, in the event of unexpected further developments, it is possible that the ultimate resolution of these matters, or other similar matters, if unfavorable, may be materially adverse to the Company’s business, financial condition, results of operations or liquidity. While the Company maintains general, product, property, workers’ compensation, automobile, cargo, aviation, crime, fiduciary and directors’ and officers’ liability insurance up to certain limits that cover certain of these claims, this insurance may be insufficient or unavailable to cover such losses. In addition, while the Company believes it is entitled to indemnification from third parties for some of these claims, these rights may also be insufficient or unavailable to cover such losses. Purchase Commitments From time to time, the Company enters into long-term inventory purchase commitments with minimum purchase requirements for raw materials and finished goods to ensure the availability of products for production and distribution. These commitments may have a significant impact on levels of inventory maintained by the Company.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) and the rules of the U.S. Securities and Exchange Commission (“SEC”). The year-end consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by US GAAP. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair statement of the results for interim periods have been included. Results for interim periods should not be considered indicative of results for a full year. These financial statements and related notes contain the accounts of DENTSPLY SIRONA Inc. and Subsidiaries (“Dentsply Sirona” or the “Company”) on a consolidated basis and should be read in conjunction with the consolidated financial statements and notes included in the Company’s most recent Form 10-K for the year ended December 31, 2018. The accounting policies of the Company, as applied in the interim consolidated financial statements presented herein are substantially the same as presented in the Company’s Form 10-K for the year ended December 31, 2018, except as may be indicated below.
Revenue Recognition	Revenue Recognition At March 31, 2019, the Company had $28.7 million of deferred revenue recorded in Accrued liabilities in the Consolidated Balance Sheets. The Company expects to recognize significantly all of the deferred revenue within the next twelve months.
Accounts and Notes Receivable	Accounts and Notes Receivable The Company records a provision for doubtful accounts, which is included in Selling, general and administrative expenses in the Consolidated Statements of Operations.
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) with subsequent amendments (collectively, “Topic 842”). The Company adopted the new leasing standards on January 1, 2019 using the modified retrospective approach transition method. Results for reporting periods beginning after January 1, 2019 are presented under ASC 842, while prior periods are not adjusted and continue to be reported in accordance with historic accounting under ASC 840. The Company elected the package of practical expedients permitted under the transition guidance within the standard, which eliminates the reassessment of past leases, classification and initial direct costs. The Company did not elect to adopt the hindsight practical expedient. The Company recognized material right-of-use assets and liabilities in the Consolidated Balance Sheets for its operating lease commitments with terms greater than twelve months. See Note 8, Leases for additional information. The impact of adopting this standard, by financial statement line item, on January 1, 2019 was as follows: (in millions) Balance at Assets Operating lease right-of-use assets, net 167.1 Property, plant, and equipment, net 1.8 Liabilities Accrued liabilities $ 39.4 Notes payable and current portion of long-term debt 0.2 Long-term debt 1.5 Operating lease liabilities 126.5 In August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging.” This newly issued accounting standard improves the financial reporting and disclosure of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. The amendments in this update make improvements to simplify the application of the hedge accounting guidance in current US GAAP based on the feedback received from preparers, auditors, users and other stakeholders. More specifically, this update expands and refines hedge accounting for both nonfinancial and financial risk components and aligns the recognition and presentation of the effects of the hedging instruments and the hedged items in the financial statements. The effect of adoption should be reflected as of the beginning of the fiscal year of adoption. For cash flow and net investment hedges existing at the date of adoption, an entity should apply a cumulative-effect adjustment related to eliminating the separate measurement of ineffectiveness to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the beginning of the fiscal year that an entity adopts the amendments in this update. The amended presentation and disclosure guidance is required only prospectively. The Company adopted this accounting standard during the quarter ended March 31, 2019. The adoption of this standard did not materially impact the statements of operations, financial position, cash flows and disclosures. Recently Issued Accounting Pronouncements Not Yet Adopted In August 2018, the FASB issued ASU No. 2018-14 "Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans." This newly issued accounting standard changes disclosure requirements for defined benefit plans, including removal and modification of existing disclosures. The amendments in this standard are required for fiscal years ending after December 15, 2020. Early adoption is permitted. The amendments should be applied on a retrospective basis for all periods presented. The Company is currently assessing the impact that this standard will have on its financial position, results of operations, cash flows and disclosures.
