What causes temporomandibular disorders (TMD)?

The causes of TMD are not always easy to diagnose. Your dentist can best help diagnose the problem.

Some TM problems result from arthritis, dislocation or injury. All of these conditions can cause pain and dysfunction. Muscles that move the joints are also subject to injury and disease.
