Here are some suggested TMJ exercises
Exercises of gentle opening and closing the mouth can be practiced on waking, before meals and at bedtime.
Increase your movements gradually, eventually opening as widely as possible but not to the extent of causing any pain. To do this, hold your chin between your forefinger and thumb, apply mild pressure backwards, slowly opening your mouth while keeping the lower jaw pressed back as far as possible. After holding your mouth open for 2 – 5 seconds, slowly close it. Pause and then slowly repeat this exercise.
Repeat this programme six times each session, 2 – 4 times daily.
