Temporomandibular joint disorder (TMD) occurs as a result of problems with the temporomandibular joint (TMJ), jaw muscles and nerves on one or both side of the head that result in jaw, face, and head and neck pain. TMD is not directly related to any one cause, but dentists believe possible causes can be attributed to a variety of issues.
What causes TMJ problems?
- Grinding or clenching the teeth, which puts a lot of pressure on the joint
- Dislocation of the soft cushion or disc between the ball and socket
- Presence of osteoarthritis or rheumatoid arthritis in the joint
- Stress, which can cause a person to tighten facial and jaw muscles or clench the teeth
Temporomandibular disorders (TMD) occur as a result of problems with the jaw, jaw joint and surrounding facial muscles that control chewing and moving the jaw. These disorders are often incorrectly called TMJ, which stands for temporomandibular joint.
