Suboxone Tooth Decay Lawsuit

Thousands of patients who used Suboxone film strips to treat opioid use disorder developed severe, unexpected tooth decay. Lawsuits allege that Indivior, the maker of Suboxone film, failed to warn patients and doctors about this serious dental risk for years.

What Is Suboxone?

Suboxone is a prescription medication that combines buprenorphine and naloxone to treat opioid use disorder (OUD). It works by reducing cravings and blocking the euphoric effects of opioids, making it a key tool in medication-assisted treatment (MAT) programs. The FDA approved Suboxone tablets in 2002 and the film strips in 2010.

The film version quickly became the dominant form of the drug. Patients place the film under the tongue or between the cheek and gum, where it dissolves over several minutes. This delivery method, called sublingual or buccal administration, sits in direct and prolonged contact with tooth enamel. That contact is at the center of the Suboxone lawsuit.

Millions of Americans have used Suboxone as part of their recovery. According to the Substance Abuse and Mental Health Services Administration (SAMHSA), more than 3.5 million people were prescribed buprenorphine-based medications in 2021 alone. Many of them used the film formulation without any knowledge of its link to tooth damage.

The Core Allegation: A Hidden Dental Risk

The central claim in the Suboxone lawsuit is that Indivior knew — or should have known — that the film formulation caused severe tooth decay, but failed to warn patients or healthcare providers for more than a decade. Plaintiffs argue this is a classic failure-to-warn defective product claim rooted in product liability law.

Suboxone film is acidic. When it dissolves in the mouth, it lowers the pH around the teeth, which strips away enamel over time. Unlike a pill you swallow quickly, the film sits in contact with teeth for several minutes during each dose. Patients who take Suboxone multiple times per day face repeated acid exposure throughout the day.

Attorneys and consumer advocates argue that Indivior had access to post-market safety data flagging dental problems long before the FDA required a label change. Internal documents and adverse event reports are expected to play a central role in these cases. This is the type of evidence that often drives significant results in defective product claims.

The FDA's 2022 Warning

In January 2022, the FDA issued a Drug Safety Communication requiring new warnings on all buprenorphine-containing medications about dental problems. This was a landmark moment in the Suboxone litigation. The FDA's own analysis found 305 cases of serious dental adverse events reported to the agency between 2002 and 2020 — and acknowledged this figure almost certainly undercounts the true number.

The FDA noted that the dental problems occurred even in patients who had no prior history of dental disease. Problems appeared as early as a few weeks after starting treatment and included tooth decay, cavities, cracked teeth, tooth loss, and oral infections. The agency directed manufacturers to update prescribing information and patient medication guides.

For litigation purposes, the 2022 FDA warning is significant for two reasons. First, it validates that the risk is real and was underreported. Second, it establishes that the risk was not adequately disclosed to patients for years before the warning was issued. Plaintiffs argue they would have made different decisions about their treatment — or at least taken protective dental measures — if they had been properly warned.

Dental Injuries Linked to Suboxone Film

The dental injuries reported in the Suboxone lawsuits range from manageable to severe and permanently disfiguring. Patients describe finding out during routine dental checkups that their teeth had been rapidly deteriorating, with some losing multiple teeth within a year or two of starting the medication.

Common Injuries Reported

• Severe and rapid tooth decay (caries)
• Tooth fractures and crumbling enamel
• Multiple tooth extractions
• Need for root canals and crowns
• Oral infections and abscesses
• Complete tooth loss requiring dentures or dental implants

The Financial and Emotional Toll

Dental restoration costs are often devastating. Full-mouth reconstruction can cost $30,000 to $90,000 or more. Many Suboxone patients were already in financial recovery from the challenges associated with opioid use disorder, making these unexpected dental bills especially crushing. Lawsuits seek compensation for past and future dental costs, pain and suffering, and loss of quality of life.

There is also a stigma element that plaintiffs raise. Tooth loss and visible decay can affect employment prospects, relationships, and mental health. Some plaintiffs describe hiding their smiles or avoiding social situations because of the embarrassment caused by their Suboxone-related dental damage.

Who May Qualify for a Suboxone Lawsuit?

You may qualify for a Suboxone tooth decay lawsuit if you used the film formulation and developed significant dental injuries during or after treatment. Eligibility is not guaranteed, but several factors increase the strength of a claim.

General Eligibility Factors

• You used Suboxone film strips (not tablets) for opioid use disorder treatment
• You developed dental problems — decay, fractures, tooth loss — during or after use
• You had no significant pre-existing dental disease before starting Suboxone film
• You have dental records documenting the damage
• Your dental injuries required treatment — fillings, extractions, root canals, implants

Prior dental problems do not automatically disqualify you. If your dental health was stable and then rapidly deteriorated after starting Suboxone film, attorneys will evaluate whether the drug likely contributed to or accelerated the damage. The key question is causation — did the film cause or significantly worsen the dental injury?

Suboxone Film vs. Tablet: A Critical Distinction

The dental injury lawsuits focus specifically on Suboxone film strips, not the original Suboxone tablets. This distinction matters enormously for eligibility.

Generic versions of the buprenorphine/naloxone film may also be covered by ongoing litigation. If you used a generic film strip rather than brand-name Suboxone, you may still have a valid claim. Attorneys handling these cases can evaluate which manufacturer is the appropriate defendant.

Litigation Status and MDL Consolidation

The Suboxone tooth decay lawsuits have been consolidated into a federal Multi-District Litigation (MDL) to streamline pretrial proceedings. MDL No. 3092 is pending in the Northern District of Ohio before Judge David A. Ruiz. As of mid-2026, thousands of individual cases have been filed, making this one of the more active pharmaceutical MDLs in the country.

An MDL is not a class action. Each plaintiff retains their individual case, and any settlement or verdict applies to individual circumstances. To understand how MDLs differ from class actions, see our guide to what is a mass tort? for a full breakdown.

The MDL process typically moves through bellwether trials — a small set of representative cases tried to juries to give both sides a realistic sense of case value. These results tend to drive settlement negotiations. In the Suboxone MDL, bellwether selections and discovery are ongoing. No global settlement has been announced as of June 2026, but settlement discussions are expected to intensify as discovery closes.

The Suboxone litigation sits alongside other active pharmaceutical mass torts that LawfareClaims tracks, including cases involving NEC infant formula, hair relaxers, and CPAP devices.

Potential Settlement Value

Settlement values in the Suboxone lawsuit vary widely based on the severity of dental injuries and individual case factors. No official settlement grid has been announced, but attorneys handling these cases point to several compensation categories.

Factors That Affect Compensation

• Severity of injury: Complete tooth loss commands higher values than a single crown or filling
• Treatment costs: Documented dental bills are a foundation for economic damages
• Duration of Suboxone use: Longer exposure may correlate with more extensive damage
• Pre-existing dental health: Strong prior dental records showing healthy teeth strengthen causation arguments
• Age and life expectancy: Younger plaintiffs with decades of dental maintenance costs ahead often receive higher awards

Comparable pharmaceutical failure-to-warn settlements — such as cases involving Risperdal and Reglan — have ranged from tens of millions to over a billion dollars in total payouts across all plaintiffs. Individual recoveries in drug injury cases with severe harm have sometimes reached six figures. These are not guarantees; every Suboxone lawsuit is evaluated on its own merits.

Attorney fees in mass tort cases are typically contingency-based, meaning you owe nothing unless you recover compensation. Most firms handling Suboxone cases charge between 33% and 40% of any recovery, deducted after the case resolves.

Filing Deadlines: Statute of Limitations

Every Suboxone lawsuit must be filed before the statute of limitations expires or the claim is permanently barred. The deadline varies by state, typically ranging from two to four years. The clock usually starts when you discovered — or reasonably should have discovered — that Suboxone caused your dental injuries.

Discovery Rule

In many states, the "discovery rule" delays the start of the limitations period until the injured person learns (or should have learned) that their injury was caused by the drug. This is important for Suboxone cases because many patients did not connect their tooth decay to their medication until after the 2022 FDA warning. If you only recently discovered the link, you may still have time to file.

Do not wait to explore your options. Collecting dental records, prescription histories, and medical documentation takes time. Attorneys need those materials to evaluate your case. If your state's deadline has passed, an attorney may still assess whether tolling rules or other exceptions apply to your situation.

You can verify your state's statute of limitations through your state court system's official website or through resources like uscourts.gov.

What to Do If You Were Harmed

Taking a few concrete steps now can protect your legal rights and strengthen any future claim. Acting early matters — memories fade, records are lost, and deadlines are unforgiving.

Step 1: Gather Your Dental Records

Request your complete dental records from every dentist you have seen in the past five to seven years. These records establish your dental baseline before Suboxone and document the progression of any damage. Dental X-rays are especially valuable evidence.

Step 2: Document Your Suboxone Prescriptions

Get prescription records showing when you started taking Suboxone film, the dosage, and how long you used it. Your pharmacy can typically provide a full dispensing history. Your prescribing doctor's records can also confirm your treatment timeline.

Step 3: Calculate Your Dental Costs

Compile all bills, insurance statements, and estimates for past and future dental work. Keep receipts for any out-of-pocket expenses. Future costs — such as implants or dentures — should be estimated in writing by your dentist.

Step 4: Consult an Attorney

Most mass tort attorneys offer free case evaluations with no obligation. They will review your records, assess eligibility, and explain what compensation you might seek. There is no cost to explore your options.

Frequently Asked Questions

What is the Suboxone lawsuit about?

The Suboxone lawsuit claims that Indivior failed to warn patients and doctors that its Suboxone film strips could cause severe tooth decay and other dental injuries. Plaintiffs argue the company knew about the risk but did not add adequate warnings to its label for over a decade.

Can I sue if I used a generic buprenorphine/naloxone film?

Possibly. Generic film formulations carry similar risks due to comparable acidic chemistry. Attorneys handling these cases evaluate claims against both Indivior and generic manufacturers. The specific defendant depends on which product you used and applicable law in your state.

Does the Suboxone film lawsuit apply to tablets too?

The primary lawsuits target the film strips, not the tablets. The film formulation has a more acidic pH and longer tooth contact time, which is the basis for most claims. If you only used tablets, your eligibility is more limited, though some attorneys will still evaluate your case.

Is there already a settlement in the Suboxone tooth decay case?

As of June 2026, no global settlement has been announced in the federal MDL. Cases are in active litigation, with discovery and bellwether proceedings ongoing. Settlements in pharmaceutical MDLs typically follow bellwether trials, which have not yet concluded.

How long do I have to file a Suboxone lawsuit?

The deadline depends on your state's statute of limitations, typically two to four years from the date you knew or should have known about the injury. Many states apply a discovery rule that may extend your deadline if you only recently connected your tooth decay to Suboxone. An attorney can confirm the exact deadline for your situation.

How much is a Suboxone lawsuit worth?

Case values vary significantly based on injury severity, dental costs, and individual circumstances. Cases involving complete tooth loss and extensive reconstruction costs typically have higher values. No settlement grid has been published yet, so any specific figure is an estimate until a settlement or verdict is reached.

Do I need to pay anything to hire a Suboxone lawsuit attorney?

Most attorneys handling Suboxone cases work on contingency, meaning there is no upfront cost. You pay legal fees only if you receive compensation. The fee is typically 33–40% of the recovery and is deducted after the case settles or goes to verdict.
