What is TMD?

TMD is the term used for temporomandibular joint dysfunction or temporomandibular joint disorder. It is also known as myofacial pain dysfunction syndrome (MPDS). It is defined as a group of disorders developed as a result of an injury to the TMJ and muscle spasm associated with severe pain and dysfunction of the joint. It is generally initiated as spasm of one or more muscles of mastication.

What are the causes of TMD occurrence?

Spasm of the muscles of mastication and TMJ injury are associated with the development of TMD. Certain habits such as forceful clenching and grinding of teeth in bruxism transmit heavy pressure to the TMJ causing injury. Stress is an important predisposing factor which is related with tightening of the facial and jaw muscles. Development of inflammatory arthritis in the TMJ can lead to TMD. Pain can occur due to movement or slipping of the articluar disc of TMJ.
