The Temporomandibular joint (TMJ) is the joint that connects the jawbone to the skull. It can be found on either side of the jaw, and is one of the most complex joints in the body. The TMJ – along with the surrounding muscles – allows the jaw to move from side to side, up and down, back and forth while chewing, swallowing and talking. When the structures that form the TMJ are out of sync, a joint disorder (called Temporomandibular joint disorder) will occur.
