TMJ is the abbreviated name of the Temporomandibular Joint that moves the jaw. TMJ problems can come from the jaw itself or from the teeth and muscles. TMJ problems could include worn or fractured teeth, sore jaw muscles, and/or “popping” and locking of the joint. A thorough examination will be done to determine what your TMJ issue may be and then appropriate treatment can be recommended for you. Treatment could include wearing a bite splint.
