I have tmj issues, both from clenching & wisdom extract. 4+ yrs ago. tried dentist suggest.s. what exercise can train my jaw to stop clenching?

TMJ Syndrome: I understand your discomfort. See article of Mayo Clinic and Video- http://howtostopgrinding.com/tag/tmj-exercises-mayo-clinic Avoid extreme jaw movements. Reflect on stresses in life- relationship, marriage, separation, unresolved feelings of worry, fear, hurt, resentment and guilt; work and finances.

Occlusal guard: Exercises, analgesics, muscle relaxants, hot and cold compresses are all good. You should seek a specialist in TMJ ( Prosthodontist). I find that an occlusal guard custom made by a dental specialist usually helps a lot and cut on the amount of medication you need.
