Temporomandibular joint

TMJ disorders cause tenderness and pain in the temporomandibular joint (TMJ) — the joint on each side of your head in front of your ears, where your lower jawbone meets your skull. This joint allows you to talk, chew and yawn.

TMJ disorders can be caused by many different types of problems — including arthritis, jaw injury, or muscle fatigue from clenching or grinding your teeth.

In most cases, the pain and discomfort associated with TMJ disorders can be alleviated with self-managed care or nonsurgical treatments. Severe TMJ disorders may need to be treated with dental or surgical interventions.
