What Is TMJ Dysfunction?
TMJ dysfunction (TMJ injury) is an injury to the Temporomandibular Joint (TMJ), the hinge joint that connects your lower jaw to the temporal bone of your skull.
The joint is in front of the ear on each side of your head. Place your fingers in front of your ears and put light pressure there while moving your jaw up and down. You will feel your Temporomandibular Joint. There are several complex components to your TMJ, such as muscle, bone, ligaments, and cartilage.
Damage or displacement of the cartilage can occur when there is a rapid acceleration/deceleration movement of the head, such as in a motor vehicle accident. TMJ Dysfunction often accompanies whiplash.
