Suboxone Lawsuit
Suboxone is a prescription medication combining buprenorphine and naloxone, used to treat opioid use disorder. The sublingual film version — a strip that dissolves under the tongue or against the cheek — was introduced by Indivior and became one of the most widely prescribed addiction treatments in the country. In January 2022, the FDA issued a safety communication warning that buprenorphine medicines dissolved in the mouth had been linked to serious dental problems, citing hundreds of adverse event reports — including cases in patients with no prior history of dental disease. A dental warning was not added to the label until June 2022, more than a decade after the film’s approval.
Why Are Suboxone Lawsuits Being Filed?
Plaintiffs allege that Suboxone film’s acidic formulation, combined with prolonged contact as the strip dissolves and the dry mouth buprenorphine can cause, erodes tooth enamel and leads to severe decay, fractures, infections, extractions, and tooth loss — and that Indivior knew of the risk for years without warning patients or providers. Indivior denies the allegations. Many plaintiffs sought treatment for addiction in good faith and did everything right, only to suffer devastating and expensive dental damage.
MDL 3092: Where the Litigation Stands
In February 2024, federal Suboxone dental injury lawsuits were consolidated into MDL 3092 in the U.S. District Court for the Northern District of Ohio before Judge J. Philip Calabrese. Because the court allows block filing — up to 100 plaintiffs per complaint — the docket’s roughly 1,800 filed cases represent a much larger number of individual claimants, with plaintiffs’ counsel reporting claims in the thousands. In 2026 the court built a core discovery pool from 100 representative cases, with depositions running into early 2027 and the first bellwether trial currently projected for March 2028. No settlements have been announced.
Injuries in the Suboxone Litigation
Reported injuries include rapid tooth decay, enamel erosion, cavities, cracked or fractured teeth, dental infections, root canals, extractions, tooth loss, and the need for crowns, implants, or dentures — often across many teeth at once.
Who May Qualify?
You may qualify for a free case review if you used Suboxone sublingual film (or generic buprenorphine/naloxone film) as prescribed and suffered significant dental injuries. Prescription records and dental treatment records are the core evidence. Statutes of limitations vary by state — commonly two to three years — and in many states the clock relates to the June 2022 label change, so time is a genuine factor in these claims.
Important: Do not stop taking Suboxone or any addiction treatment medication without talking to your doctor. The FDA has stated the benefits of buprenorphine for treating opioid use disorder clearly outweigh the dental risks, and there are precautions your care team can recommend.
