Temporomandibular Joint Disorder
The temporomandibular joint is the hinge joint connecting the lower jaw to the temporal bone of the skull, which rests in front of the ear on each side of your head. Muscles surrounding and attached to this joint are responsible for the smooth movement of the jaw, allowing you to chew food, talk and yawn.
Temporomandibular joint disorder, more commonly known as TMJ, occurs when the complex system of muscles, ligaments and bones that control the jaw are not working properly. TMJ can be caused by grinding or clenching of the teeth, head and neck posture, injury to the jaw, and stress, which can often cause tightening of the facial and jaw muscles.
Although there is no single cure for TMJ syndrome, Dr. Guinn is an excellent resource for discussing treatment options.
