Temporomandibular Joint (TMJ)

Temporomandibular joint (TMJ) disorders are very common, affecting over 10 million people in the United States. The temporomandibular joint is the small joint located in front of each ear that attaches the lower jaw to the skull. These joints work in combination with various jaw muscles and ligaments, making it possible to open and close the mouth, chew, speak, swallow, etc. When the temporomandibular joints, jaw muscles and ligaments are prevented from working together properly, a painful TMJ disorder may occur.

Although the cause of TMJ is not completely understood, research has shown that certain factors may contribute to the problem. For example, conditions that affect other joints in the body, such as arthritis, may cause or aggravate TMJ. Injury, trauma or grinding the teeth while sleeping also may lead to the condition. In addition, displacement or dislocation of the disc that is located between the jawbone and socket may result in TMJ.

Our oral and maxillofacial surgeons offer a full range of diagnostic services, as well as surgical and non-surgical treatments for TMJ disorders. Patients also have access to our Orofacial Pain Center, which specializes in conditions that cause orofacial pain, such as TMJ. In addition to pain management, services offered include relaxation techniques, biofeedback and acupuncture.
