Temporomandibular Joint (TMJ) Disorders

The temporomandibular joint (TMJ) is a hinge joint between the lower jaw (mandible) and the temporal bone of the skull, just in front and below each ear. It is also referred to as the craniomandibular joint. The movements occurring at the joint include moving the jaw up and down, forwards and backwards, and side to side. The TMJ is thus important for talking, chewing food, swallowing, and even kissing and yawning. The muscles and ligaments that surround the joint allow the smooth and painless movement of the joint.
