Botox for jaw pain: ultrasound reveals muscle changes in teeth grinders
NCT ID NCT07545200
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This small study looked at 17 adults with bruxism (teeth grinding) who received Botox injections into their jaw muscle. Researchers used ultrasound to measure muscle thickness and texture before treatment, at 14 days, and at 90 days. They also tracked pain levels. The goal was to see how the muscle changes after Botox, which may help ease jaw pain and clenching.
