Temporomandibular joint disorder is characterized by pain and compromised movement of the temporomandibular joint. The joint acts as a hinge between your jaw and cheek bone. It is responsible for moving the jaw forward, backward, and side to side.
TMD is a result of the misalignment of the jaw bone. The exact cause for misalignment is almost impossible to determine. High levels of stress is thought to be a possible factor as it can cause you to clench your teeth and tighten your jaw and facial muscles. The added pressure strains the joints of muscles of your jaw and face.
