Temporomandibular joint (TMJ) problems may be caused by traumatic arthritis, osteoarthritis, or rheumatoid arthritis. Osteoarthritis is most common in adults over 50 years of age. All forms of TMJ arthritis cause stiffness, pain, grating, swelling, and limited range of motion. Before you treat for TMJ arthritis, it's important to have confirmation that the problem is, in fact, arthritis. In most cases, an X-ray or cat scan can confirm TMJ arthritis based on the observed flattening and lipping of the condyle, the rounded prominence at the end of a bone. The exception to this is traumatic arthritis, which does not typically show up on an X-ray unless a pooling of fluids or a hemorrhage causes a widening of the joint, which would then be visible in an X-ray. The diagnosis of headache, such as cluster headache, migraine, temporal arteritis, and stroke, must be ruled out before a TMJ diagnosis, especially if you are having headache symptoms. Though arthritis cannot be cured, there are a number of treatments that can be administered to reduce jaw pain associated with arthritis.  Many doctors recommend non-steroidal anti-inflammatory drugs to treat the symptoms of traumatic TMJ arthritis.  Try sticking to a soft food diet to avoid unnecessary jaw movement.   Use a warm compress. Apply the compress for 20 minutes, then remove the compress and exercising the jaw by moving it open and shut, then side to side. Try repeating this treatment three to five times daily, as needed.  Try wearing a bite guard. This may give some patients relief from pain or discomfort. Though this type of arthritis can be painful, especially if the jaws have begun to move closer together, there are steps that can be taken to manage the pain and treat the symptoms.  Wear a mouth guard or bite plate. These can be worn during the day or overnight to help reduce pain and grating in patients with osteoarthritic TMJ pain.  Try applying a warm compress for 20 minutes, then exercising the jaw. Move the jaw open and closed, then move the lower jaw from...
