Do I Qualify for the Suboxone Lawsuit? Full Eligibility Guide

Last updated: March 2026

"Do I qualify for the Suboxone lawsuit?" That's the question most people ask first. The answer depends on a few specific factors — this page walks through each one.

Short version: if you used Suboxone sublingual film for six months or more and developed significant dental damage — cavities, enamel erosion, extractions, or tooth loss — you may qualify. Here's how each requirement works in practice.

Quick Eligibility Checklist: Do I Qualify for the Suboxone Lawsuit?

If all five boxes apply to you, speak with a mass tort attorney. The consultation is free, there is no cost to file, and attorneys work on contingency — they only get paid if you do.

Requirement 1: You Used the Film, Not the Tablet

This is the single most important eligibility factor. The Suboxone lawsuit applies to the sublingual film only — the thin rectangular strip you place under your tongue to dissolve. It does not apply to Suboxone tablets, buprenorphine pills you swallow, or injectable buprenorphine products.

Why does the form matter so much? The film's delivery method is what causes the dental damage. When the film dissolves under your tongue, it stays in direct contact with your teeth and gums for 5 to 15 minutes per dose. The film contains acidic excipients — including citric acid — that maintain a pH of approximately 3.4 throughout dissolution. At that pH, tooth enamel begins to break down. With twice-daily dosing over months or years, the cumulative acid exposure is enormous.

A swallowed tablet moves through your mouth in seconds and never has prolonged contact with teeth. The tablet's excipient profile is also different. That is why the dental damage pattern is specific to the film — and why the lawsuit is too.

How to Confirm Which Form You Used

• If you placed a thin strip under your tongue: that is the film
• If you swallowed a pill: that is the tablet
• Check your prescription bottles: look for the words "sublingual film," "SL film," or "buprenorphine/naloxone film"
• Your pharmacy fill history will show the National Drug Code (NDC) — an attorney can verify the formulation from this
• Your prescribing doctor's records will show which form was prescribed

Generic versions also qualify. The lawsuit is not limited to brand-name Suboxone. Generic sublingual buprenorphine/naloxone films made by other manufacturers are included if they are the same film formulation. The harm is caused by the film delivery mechanism and acidic excipients — which generics share.

Requirement 2: How Long You Used the Film

The lawsuits focus on patients with significant ongoing use of Suboxone film — not a brief trial period. Most mass tort attorneys look for at least 6 months of continuous or near-continuous use as a minimum, with stronger cases typically involving one year or more.

Duration matters because the dental damage from Suboxone film is cumulative. Enamel erosion and decay build up over time with repeated acid exposure. A patient who used the film twice daily for two years has had roughly 1,460 sessions of direct acid contact on their teeth. That accumulation is what drives the level of damage seen in many lawsuits.

That said, duration is not the only factor. Some patients develop significant damage in shorter timeframes — particularly if they had pre-existing dry mouth, used higher doses, or had other compounding risk factors. If you used the film for less than six months but experienced serious dental damage, the claim may still be worth evaluating.

How to Document Duration

• Request a complete prescription history from your pharmacy — going back to the first fill of the film
• Request records from your prescribing physician covering the dates you were on the film
• Your state's Prescription Drug Monitoring Program (PDMP) maintains records of controlled substance prescriptions and may have this history even if you moved or changed pharmacies

Requirement 3: Qualifying Dental Damage

Not every dental complaint qualifies. The lawsuit covers significant, documented dental damage that is connected to the period of Suboxone film use. Here is what generally qualifies — and what generally does not.

Dental Problems That Typically Qualify

• Rapid tooth decay and cavities — especially multiple cavities developing within a short period in someone who previously had good dental health
• Enamel erosion — documented breakdown of tooth enamel, particularly with a distribution pattern consistent with film contact areas
• Tooth fractures — teeth cracking or breaking due to weakened enamel
• Tooth loss requiring extraction — teeth pulled because of decay rather than trauma or pre-existing gum disease
• Oral infections and abscesses — infections at the root or in the gum requiring treatment, antibiotics, or extraction
• Extensive restorative work — needing crowns, root canals, dental implants, dentures, or bridges because of decay attributable to the film

Dental Problems That Generally Do Not Qualify

• Mild tooth sensitivity alone, without documented structural damage
• Gum disease that clearly predated Suboxone film use
• Dental problems with a clear alternative cause — such as significant methamphetamine use documented in the dental record, severe malnutrition, or a prior injury
• Purely cosmetic concerns — minor discoloration or staining without decay or structural damage

The strength of your claim increases with the severity of documented damage and the cost of treatment needed. A patient who had 8 teeth extracted and now needs implants has a substantially stronger case than someone with two fillings.

Requirement 4: The Damage Is Not Fully Explained by a Pre-Existing Condition

Attorneys will review your dental history to assess whether the film caused or significantly worsened your dental damage — or whether there is a competing explanation. This is one area where people in recovery sometimes worry unnecessarily.

You do not need to have had perfect teeth before starting Suboxone film. Many people entering medication-assisted treatment have some pre-existing dental issues. What matters is whether the film made things significantly worse, caused new damage, or accelerated decay beyond what would otherwise be expected.

Helpful evidence includes:

• Dental X-rays from before you started Suboxone film showing your baseline dental health
• Dental records showing a clear deterioration in dental health after starting the film
• A dentist's professional notation that your decay pattern is consistent with prolonged acid exposure
• Evidence that the pattern of damage corresponds to film-contact areas of the mouth

A Note on Stigma and Recovery History

Some people worry that their history of opioid use will be used against them in a lawsuit — that defendants will claim "of course their teeth were bad, they were an addict." This is a concern that experienced mass tort attorneys are fully prepared to address. Many Suboxone film users entered treatment with good or reasonable dental health and only developed severe problems after starting the film. That before-and-after documentation is powerful.

Additionally, the FDA's own 2022 warning specifically noted that dental problems occurred even in patients with no prior dental history. That makes it harder for Indivior to claim patient behavior was the cause.

Requirement 5: You Are Within the Filing Deadline

Every personal injury lawsuit has a statute of limitations — a deadline after which you lose the right to file. Missing this deadline is fatal to a claim, regardless of how strong the underlying case is.

For Suboxone dental claims, the statute of limitations typically runs from one of two dates:

• The date you discovered your dental damage — meaning when a dentist first documented significant problems; OR
• The date you reasonably should have known the damage was connected to Suboxone film — which in many cases may be after the FDA's January 2022 warning, since that is when the connection became widely known

Most states have a 2-year or 3-year statute of limitations for personal injury claims. Some states are shorter. A few states have special rules for pharmaceutical injury cases or the discovery rule that may extend the deadline.

If you noticed significant dental damage more than a year ago and have not yet consulted an attorney, contact one immediately. Do not assume it is too late — but do not wait to find out.

What About Using Both Film and Tablet?

Some patients were on the film for part of their treatment and switched to tablets at some point. If you used the film for a significant period and developed dental damage during that period, you may still qualify even if you later switched to tablets. The key question is whether the dental damage occurred during or is attributable to the film-use period — not whether you are currently on the film.

Will Filing a Lawsuit Affect My Recovery?

No. Filing a civil lawsuit will not affect your Suboxone prescription, your relationship with your prescribing doctor, or your participation in any recovery program. This is entirely civil litigation — completely separate from your medical care.

You can continue your treatment as directed by your doctor while simultaneously pursuing a legal claim. Many patients in MDL 3092 are doing exactly that.

What Documents Do I Need to Qualify?

You do not need to have everything gathered before consulting an attorney — they can help you collect records. But having these ready speeds the process:

• Current dental records and X-rays documenting your dental problems
• Older dental records from before you started Suboxone film (ideally showing earlier, better dental health)
• Prescription records confirming you were prescribed Suboxone film (not just tablets), the dosage, and the dates
• Pharmacy fill history confirming the film formulation
• Any dental treatment estimates or bills for work already done or needed

How to Start the Process

1. Get a dental evaluation — see a dentist and get your current dental problems fully documented.
2. Request old dental records — ask your prior dentists for records from before your Suboxone film use began.
3. Gather prescription records — confirm what you were prescribed, when, and for how long.
4. Contact a mass tort attorney for a free consultation — describe your situation, show your records, and get a professional assessment of your claim.
