Retraining the joint to function the proper way, or correcting the way the teeth bite together, the stress placed on the TMJ can be eliminated, thereby reversing the painful conditions caused by TMJ disorder. Training the jaw to position itself back into a relaxed position can be achieved by using a splint-method. Or, an orthodontic approach may be used to correct the way the upper and lower teeth bite together, thus reducing abnormal pressure and function of the jaw.
