Temporomandibular disorder (TMD) is a painful condition in the joint that opens and closes the mouth. These temporomandibular joints are the small joints in front of each ear. They attach the lower jaw (mandible) to the skull. The disorder may affect the jaw joint or the muscles surrounding it. The disorder can include:
Damage to the joint surface or intra-articular disk
A splint or mouth guard can be made to relax the jaw muscles. This will prevent clenching and grinding of the teeth. The guard is usually worn at night. Correction of bite abnormalities by a dentist or orthodontist is sometimes needed.
