What are temporomandibular disorders?

Temporomandibular disorders [TMD] are commonly characterised by pain or tenderness of the temporomandibular joint and/or surrounding muscles, joint sounds and limitation or loss of jaw movement.

Note on terminology
Temporomandibular Disorders or TMD is a collective term used to describe a group of different diagnoses affecting the jaw joint, the muscles that control the movement of the lower jaw and the contacts between the teeth. The term 'Temporomandibular Joint or TMJ is sometimes used [ as in "I think I have a TMJ" or "this is a TMJ patient"], when it would make more sense to use the generic term 'TMD'.

There are many types of TMD, the signs and symptoms of which can overlap, making the diagnosis and management of patients subject to confusion and controversy. TMDs are also far more prevalent than generally recognised and many myths and misconceptions surround the subject. These factors all too often lead to misdiagnosis and/or inappropriate treatment (click here to see 2 real world examples of this).

It is the aim of this web site to raise awareness of temporomandibular disorders, providing a balanced overview of the subject for dental practitioners and students, as well as for the patients themselves. It is presented on two levels. The superficial level is aimed at being useful for the general public, whereas the deeper level is aimed at the undergraduate and post graduate dental student of the subject.
