Something else to try . . .

From Michael Reed Gach's book Accupressure Potent Points -- press Stomach 6, the Jaw Chariot point, with "firm, prolonged pressure" for two minutes, three times/day.

He says he used it himself to cure himself of TMJ and clenching his jaw at night while he slept.

The point is between the upper and lower jaws on the masseter muscle, the muscle that bulges when you clench your back teeth.
