Can the jaw joint become inflamed?

Arthritis means inflammation of a joint. In the jaw it may cause pain and restricted movement. The cause needs assessment; pain at the joint alone does not establish arthritis.

Locate the joint

The joint in front of the ear connects the mandible to the skull. Joint inflammation is not automatically a tooth problem.

02 / 03

Consider the cause

Rheumatic disease can involve the jaw joint. Other joint symptoms, medical conditions and medicines matter.

Coordinate assessment

Dental assessment and, where indicated, further medical investigation guide care. A splint is not a general treatment for every inflamed joint.

Quick answers

Arthritis or osteoarthritis?

Inflammatory and degenerative joint changes can overlap; the terms are not interchangeable.

Does clicking prove inflammation?

No. A sound alone cannot establish that diagnosis.

When is help urgent?

Rapid swelling, fever or major difficulty eating or drinking warrants same-day medical or dental assessment.
