Temporomandibular Joint Disorder

Chapter: What is the Temporomandibular Joint?

The temporomandibular joint (TMJ) is a joint that slides and rotates just in front of your ear, consisting of the temporal bone (side of the skull) and the mandible (lower jaw). Chewing muscles connect the lower jaw to the skull, allowing you to move your jaw forward, sideways and open and close.


The joint works properly when the lower jaw and its joint (both the right and left) are synchronized during movement. TMD may occur when the jaw twists during opening, closing or side-motion movements. These movements affect the jaw joint and the muscles that control chewing.
