Temporomandibular joint disorders, often called TMJ, occur as a result of problems with the jaw, jaw joint, and surrounding facial muscles that control chewing and moving the jaw. Causes include injury to the jaw joint, grinding or clenching the teeth, dislocation of the soft cushion or disc between the ball and socket, and osteoarthritis or rheumatoid arthritis in the temporomandibular joint. Symptoms include tenderness or pain in the face, jaw joint area, neck and shoulders, a clicking sound in the jaw joint when opening or closing the mouth, headaches, toothaches, neckaches, and tinnitus. Treatment may include wearing a mouth guard at night, using muscle relaxants, and low-level laser therapy to reduce inflammation.
