Simple jaw exercises may offer Drug-Free relief for jaw pain sufferers
NCT ID NCT07303361
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a combination of a specific jaw muscle technique and neck exercises could reduce pain and improve jaw function in people with temporomandibular disorder (TMD) and teeth grinding (bruxism). Sixty adults with TMD and bruxism were split into two groups: one received the active treatment (weekly jaw technique sessions plus daily neck exercises), while the other received standard care with a placebo-like neck technique. The researchers measured pain sensitivity, jaw opening, and other factors before and after the four-week program.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Mandibular muscle energy technique and cranio-cervical motor control exercises
- What this could lead to
- If it works, this could point toward a simple, non-drug exercise program to reduce jaw pain and improve daily function for people with TMD and bruxism.
- What could go wrong
- This is a small, completed trial with only 60 participants. The results may not apply to everyone, and the placebo group also received some care, so the added benefit of the active technique may be small.
