Jaw Pain and Dysfunction The jaw (or TMJ for Temporo Mandibular Joint) is frequently unacknowledged as a source of pain in many head, neck, face, and vocal conditions. People who experience headaches, motor vehicle accidents, sport or work site injuries, often have jaw issues that can accumulate to overwhelming levels. Clenching the teeth is a very common habit during sleep, while concentrating, or from stress. This often results in an accumulation of both compressive forces in the joints and asymmetrical muscle tightness which can lead to clicking, pain and ultimately joint damage. Resolving the joint compression and muscular tightness can re-pattern the jaw mechanics and save pain and difficulties decades later.
