Temporomandibular joint syndrome

Pain and other symptoms affecting the head, jaw, and face, thought to result when the temporomandibular joints and the muscles and ligaments attached to them do not work together correctly. Causes include spasm of the chewing muscles, an incorrect bite (see malocclusion), jaw, head, or neck injuries, or osteoarthritis. Common symptoms include headaches, tenderness of the jaw muscles, and aching facial pain. Treatment involves correction of any underlying abnormality, analgesic drugs, and, in some cases, injection of corticosteroid drugs into the joint.
