The jaw is a hinge joint connecting the mandible to the skull, and is one of the most often used joints in the body. The articular disk separates the condyle head of the mandible and the skull, and when this disk is misplaced it will cause Temporal Mandibular Joint Dysfunction (TMJ). TMJ can restrict mobility in the jaw and cause discomfort. TMJ is often accompanied by clicking, grinding, or crunching noises when opening the mouth. Often, TMJ is related to muscle stress and this can be alleviated with simple chiropractic adjustments.
