Temporomandibular Disorders (TMD)

Condition Basics

What are temporomandibular disorders (TMDs)?

Temporomandibular disorders (TMDs) is the name given to several problems with jaw movement and pain in and around the jaw joints. They cause pain when you talk, chew, swallow, or yawn.

You may also hear TMDs called TMJ or TM problems.

The jaw joints, or temporomandibular (TM) joints, connect the lower jawbone (mandible) to the skull. These flexible joints are used more than any other joint in the body. They allow the jaw to open and close for talking, chewing, swallowing, yawning, and other movements.

What causes them?

TMDs are caused by muscle tension, often triggered by stress. Clenching or grinding your teeth can tire the jaw muscles, leading to muscle spasms, tissue damage, pain, and sore muscles. A TMD can also start with an injury to the jaw joint or a joint disease like osteoarthritis or rheumatoid arthritis.

What are the symptoms?

TMDs can affect the jaw and jaw joint as well as muscles in the face, shoulder, head, and neck. Common symptoms include joint pain, muscle pain, headaches, joint sounds, trouble with fully opening the mouth, and jaw locking.

How are they diagnosed?

There is no one way to diagnose a TMD. Your doctor can check your condition with a physical exam and by asking questions about your health. In some cases, an X-ray, CT scan, or MRI is also used to check for bone or soft tissue problems related to symptoms of a TMD.

How are TMDs treated?

The focus of TMD treatment is to ease pain in the jaw joint and restore normal jaw movement. Initial treatment involves over-the-counter pain medicine and self-care at home. Splints can help reduce teeth grinding and clenching. Your doctor may suggest other treatments as well. Surgery isn't usually done to treat TMDs.
