What is TMJ?
TMJ refers to the temporomandibular joint which connects the lower jaw (mandible) to the bone at the side of your head (temporal bone). When someone has a temporomandibular joint and muscle disorder, they may experience pain in the jaw joint and muscles, stiffness, limited opening, clicking and popping of the joint when opening or closing, and sometimes a change in how the upper and lower teeth overlap. The exact cause of TMJ disorder is not known, although trauma to the jaw or joint may play a role and it can be more prevalent in those with higher stress levels.
