Botox for grinding teeth: does it change jaw muscle over time?

NCT ID NCT07266064

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looked at 27 adults with sleep bruxism (teeth grinding) who got Botox injections in their jaw muscles every six months for two years. Researchers used ultrasound to measure fat buildup in the muscle before each injection. The goal was to see if repeated Botox causes long-term structural changes in the jaw muscle.
