Mouthguard study aims to soothe jaw and neck pain
NCT ID NCT07090551
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a custom mouthguard (occlusal splint) can reduce pain and improve muscle function in people with teeth grinding (bruxism) and related jaw and neck muscle pain. About 40 adults will be split into two groups: one gets the mouthguard right away, the other waits 12 weeks. Researchers will use ultrasound to measure muscle thickness and stiffness before and after treatment, and also track pain and jaw movement with questionnaires.
