General Discussion

Temporomandibular joint (TMJ) dysfunction is a general term for a group of conditions that affect the temporomandibular joint. The TMJs are small joints that connect the lower jaw (mandible) to the temporal bone of the skull. TMJ dysfunction is characterized by pain of the jaw joint that is made worse during or after eating or yawning. It can cause limited jaw movement and clicks and pops during chewing. In severe cases, pain can radiate into the neck, shoulders and back.
