The disc helps to maintain smooth movement and position between the two joint bones. Changes in disc position are often the cause of noises occuring in the joint during mouth movements. The disc itself does not have sensation but the surrounding ligaments such as the posterior attachment are sensitive and may become painful due to a disc disorder. The posterior attachment connects the disc to the mandibular fossa. Lateral pterygoid muscle - when this muscle contracts the condyle is pulled forward and down producing mouth opening.
Ligaments attach the disc to the lower bone and the upper fossa.
Changes in disc position are common and can cause jaw clicking and locking. A ligament attached to the upper and lower joint bones surrounds the joint parts. Ligaments help to provide stability to the disc and condyle during movements. The health of your mouth can affect your whole body.
