Suboxone Tooth Decay Lawsuit in Michigan

What Michigan residents should know

Michigan residents are not necessarily limited to filing only in Michigan state court. Many mass tort claims may be evaluated by national firms, filed in federal court, coordinated through MDL proceedings, or handled through another legal process.

State law may still matter for deadlines, damages, claim evaluation, and certain procedural issues.

What stands out about Suboxone litigation in Michigan?

Tooth-decay cases filed by Michigan residents in the Eastern or Western District of Michigan are transferred into MDL-3092 in the Northern District of Ohio for coordinated pretrial proceedings before Judge J. Philip Calabrese.

Michigan participated in the standard federal Indivior multistate settlements — the 2019 Reckitt Benckiser $1.4 billion settlement, the 2021 Indivior $300 million Medicaid-fraud settlement, and the June 2023 multistate $102.5 million Suboxone antitrust settlement — but did not serve as a lead negotiating state or on the executive committee for the July 2024 $86 million settlement in principle. As of mid-2026, a review of the Michigan Attorney General’s news archive did not surface an independent Michigan AG action against Indivior beyond multistate participation; this is an absence-of-evidence statement rather than a guarantee.

Michigan’s personal injury statute of limitations is generally three years (Mich. Comp. Laws § 600.5805(2)).

What is the filing deadline for Suboxone lawsuits in Michigan?

For a Michigan resident researching Suboxone claims, the starting point is usually Michigan's general personal injury period: 3 years under Mich. Comp. Laws § 600.5805(2). That is only a starting point, not a final legal deadline for every person.

The real filing deadline can depend on diagnosis date, when the injury and possible cause were discovered, exposure location, wrongful-death issues, prior claim paperwork, and whether the case is filed directly, transferred to an MDL, or handled through another process.

Discovery-rule note: Michigan applies limited discovery-based accrual rules; latent-injury treatment varies by claim type.

How long do Michigan residents have to file?

Michigan's personal injury statute of limitations applicable to product liability claims is 3 years (Mich. Comp. Laws § 600.5805(2)). Accrual timing, tolling, and repose periods can still change the real deadline in an individual case.

• Filing period: 3 years — Mich. Comp. Laws § 600.5805(2).
• Discovery rule: Michigan applies limited discovery-based accrual rules; latent-injury treatment varies by claim type.

Because the controlling deadline depends on diagnosis date, discovery facts, exposure history, wrongful-death rules, and how the claim is filed, only a licensed attorney can confirm the deadline that applies to a specific situation. This page is general legal information, not legal advice.
