The temporomandibular joint is the joint that connects your jaw to your skull.
When this joint is injured or damaged, it can lead to a localized pain disorder called temporomandibular joint (TMJ) syndrome.
Causes of temporomandibular joint (TMJ) syndrome include injury to the teeth or jaw, misalignment of the teeth or jaw, teeth grinding, poor posture, stress, arthritis, and gum chewing.
The temporomandibular joints are complex structures containing muscles, tendons, and bones. Injury to or disorders of these structures can all result in pain in the jaw area.
Jaw pain may occur on one side or on both sides, depending upon the cause.

Also depending upon the exact cause, the pain may occur when chewing or may occur at rest.
Additionally, other medical conditions not related to the TMJ may cause perceived pain in the jaw area.
