Light therapy could soothe your aching jaw

This study tests whether shining specific light wavelengths (635, 940, or 1064 nm) on the jaw muscles can reduce pain and improve jaw function in people with chronic jaw muscle disorder (TMD). About 45 adults with moderate-to-severe jaw pain lasting over 3 months will receive several light therapy sessions. The goal is to find which wavelength works best for pain relief and daily activities.
