TMJ vs. TMD

Temporomandibular Joint Disorders (TMD) generally fall into 3 main categories:

• Myofascial pain, the most common form of TMD, which is pain or discomfort or pain in the muscles that control jaw function and the neck and shoulder muscles.

• Internal derangement of the joint, meaning a dislocated jaw or displaced disc, or injury to the condyle.

• Degenerative joint disease, such as osteoarthritis or rheumatoid arthritis in the jaw joint.

A person can have one or more of these symptoms at the same time.

Symptoms of a TMJ Disorder include:

• Limited movement or locking of the jaw

• Radiating pain in the face, neck or shoulders

• Painful clicking, popping or grating sounds in the jaw joint when opening or closing the mouth

• A sudden, major change in the way the upper and lower teeth fit together

• Headaches, earaches, dizziness, and hearing problems
