The temporomandibular joint (TMJ) is the joint that connects the jaw to the temporal bones of the skull. Temporomandibular joint disorder, known more commonly as TMD, occurs when there are problems with the muscles and jaws in the face.

Often, TMD arises from problems with the muscles in the jaw or the joint itself. Your jaw may be popping or clicking or even "getting stuck" every now and then. It is important to see a dentist or dental specialist for a consultation to determine the cause of the oral problem.
