MEDICAL ANIMATION TRANSCRIPT: TMJ disorders are problems with the jaw joint and chewing muscles. The temporomandibular joint, or TMJ, is where your lower jaw meets your skull. There are two temporomandibular joints, one in front of each ear. Each joint connects the lower jaw to the temporal bones of the skull. A soft cushion called an articular disk sits between the bones. The rounded ends of the jawbone and the disks slide forward when you open your mouth. They slide back and forth when you close your mouth. Muscles attach to the jaw and control its movement. The joint can open and close like a hinge. But unlike many other joints, the TMJ can also slide back and forth and from side to side. Because of this gliding ability, the joint relies on the jaw muscles and teeth to guide it into the correct position when you open and close your mouth. In one type of TMJ disorder, the disk can move out of place. In a second type, the joint can be damaged due to medical problems such as arthritis, in which the joint becomes inflamed and deteriorates. And in a third type, painful spasms in the jaw muscles may occur. Other health problems such as bruxism can also cause symptoms in the joint. The most common symptom of TMJ disorders is pain in the joint and nearby muscles. Sometimes TMJ pain is mistaken for an earache because the ear is so close to the joint. You may experience headaches from the pain that originates in the muscles around your jaw and temple. Other symptoms include trouble moving your jaw, a painful clicking sound when you open or close your mouth, and changes in the way your teeth fit together. If you have questions about TMJ disorders, talk to your doctor.
