How to Join the Suboxone Lawsuit: Tooth Decay and Dental Injury Claims. Suboxone is a prescription treatment for opioid use disorder that combines buprenorphine, a partial opioid agonist, with naloxone to discourage misuse. It has helped many people in recovery, but the film version dissolves under the tongue, and in January 2022 the FDA warned that buprenorphine medicines dissolved in the mouth have been linked to serious dental problems. Thousands of people who developed tooth decay, cavities, infections and tooth loss are now suing, and this guide explains who may qualify and how to start with a free, confidential review through Legal Lawsuit.
What Is the Suboxone Lawsuit?
The current Suboxone litigation is a set of product liability claims against the manufacturers, led by Indivior, alleging that the sublingual film caused severe dental damage and that the companies failed to warn patients and dentists about the risk until the FDA required a label change in 2022. Federal cases are coordinated in MDL 3092 in the Northern District of Ohio. Earlier, separate cases involved antitrust and marketing allegations.
Why People Are Filing Suboxone Claims
The main allegations include:
- Dental injuries: Tooth decay, cavities, fractures, gum disease, infections and tooth loss after using the film.
- Late warnings: The dental risk was not added to the label until 2022, years after the film was introduced.
- Acidic formulation: Plaintiffs argue the film’s acidity contributed to enamel erosion when dissolved in the mouth.
- Costly treatment: Crowns, root canals, extractions, implants and dentures that many patients had to pay for themselves.
Dental Problems and Other Side Effects
Suboxone is an effective treatment, and patients should not stop it without medical advice. Its potential side effects include:
Common Side Effects
- Nausea and vomiting
- Headaches
- Sweating
- Constipation
- Sleep disturbances
Dental Injuries at the Center of the Lawsuit
- Tooth Decay, Infection and Tooth Loss
- Respiratory Issues
- Liver Damage
Other Effects
- Depression or anxiety
- Mood swings
- Mood changes in some patients
The lawsuits focus on dental harm that patients say they were never warned about.
Who Can Join the Suboxone Lawsuit?
You may be eligible if you meet most of these criteria:
- You used Suboxone film or another buprenorphine product dissolved in the mouth.
- You developed tooth decay, cavities, infections, cracked teeth or tooth loss after starting it.
- You needed dental work such as fillings, crowns, root canals, extractions or implants.
- You have prescription and dental records, or can get them, showing use and treatment.
Because filing deadlines vary by state and many started running when the FDA warning came out in 2022, have an attorney check your deadline soon.
Past Suboxone Legal Actions
The dental claims follow earlier cases over how the drug was marketed and sold:
Antitrust Settlements
In 2019, Reckitt Benckiser, Suboxone’s former parent company, agreed to pay $1.4 billion to resolve federal investigations into the marketing of Suboxone, and Indivior later reached its own government and state settlements.
Antitrust Claims
Purchasers and states alleged the company delayed generic competition by shifting patients from tablets to the patented film, and several of those cases were resolved through settlements.
Dental Injury Claims
The current wave of individual product liability claims centers on tooth decay and dental damage, coordinated in MDL 3092.
Government Actions
Government enforcement and private litigation have both scrutinized how Suboxone was promoted, and the dental cases now seek compensation for patients’ own injuries.
Why Work With a Suboxone Lawyer?
A lawyer experienced in these cases can confirm your eligibility, gather pharmacy and dental records, document the cost of past and future dental care and handle MDL requirements and deadlines. Most work on contingency, so there is usually no fee unless money is recovered, and you can focus on your health and recovery.
What a Suboxone Claim Can Cover
Depending on your case, compensation may include:
- Economic Damages
- Non-Economic Damages
- Punitive Damages
No settlement values have been published for the dental claims, so any figure you see online is an estimate. An attorney can help you understand what affects value in your case.
