Why under-the-tongue buprenorphine may harm teeth
Elucidating High Oral Fluid Exposure Mechanisms of Buprenorphine to Reduce Dental Caries
This project looks at how buprenorphine taken under the tongue may cause tooth damage in people treated for opioid use disorder.

What this research studies
If you take buprenorphine under the tongue, researchers will study how high drug levels in saliva interact with teeth and oral tissues. The team will measure buprenorphine concentrations in oral fluids, use lab and animal models to track how the drug distributes in the mouth, and examine direct effects on tooth structure. They will also test possible ways to block or reduce the tooth-damaging effects so future treatments could be safer.
Who could benefit from this research
Good fit: Ideal candidates would be people currently taking or who have recently taken sublingual buprenorphine, especially those with new or worsening dental problems.
Not a fit: People who do not use sublingual buprenorphine or whose dental issues have clear non-drug causes may not benefit from this work.
Why it matters
Potential benefit: If successful, this work could lead to ways to prevent or reduce tooth damage for people using sublingual buprenorphine.
How similar studies have performed: Reports and an FDA warning have documented tooth problems with buprenorphine use, but the specific biological mechanisms are not well understood and this approach is relatively novel.
