My daughter still has some TMJ. She wears a dental guard. We were sent to an osteopath by her neurologist. This seemed to help her clear her mind and it reduced the pn. She saw the osteopath about 6 times. She then tried acupuncture. This has done wonders for the pn. She's not going right now because it's such a distance to drive. But she can now eat and exercise without the TMJ pn interfering.
We are in the Bay area, CA and can recommend Drs here.

Best to you...
