Jaw arthritis, also known as temporomandibular joint (TMJ) disorder, is a condition that affects the jaw joint and surrounding muscles. It can cause pain, discomfort, and restricted movement in the jaw. The jaw joint connects the lower jaw to the skull. It is a small joint that allows the jaw to move up and down and side to side.
Causes of Jaw Arthritis
Jaw arthritis can have many causes, including:
- Injury to the jaw or surrounding muscles
- Stress, which can lead to teeth grinding or clenching
- Arthritis, such as rheumatoid arthritis or osteoarthritis
- Infection in the jaw joint
- Misalignment of the teeth or jaw
Symptoms of Jaw Arthritis
The most common symptoms of jaw arthritis are pain and difficulty moving the jaw. Other symptoms may include:
- Pain in the face or neck
- Pain or stiffness when chewing
- Pain or a clicking sound when opening the mouth
- Limited ability to open or close the mouth
- Swelling in the face
Treatment Options
Treatment for jaw arthritis depends on the underlying cause. Treatment options may include:
- Medication, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or muscle relaxers
- Physical therapy

- A splint or mouth guard to reduce teeth grinding and clenching
In some cases, jaw arthritis can be managed with lifestyle changes, such as avoiding hard or chewy foods and reducing stress.
