The temporomandibular system consists of three basic components; the temporomandibular joint or TMJ, the teeth,and the neuromuscular system.
Temporomandibular disorders come in many forms and varying degrees of severity. Basically TMD is a problem when you either experience pain and/or a loss of jaw function. The pain can range from a mild ache in the morning to a chronic debilitating pain. Loss of function can be mild jaw stiffness to being unable to open the jaw barely at all.
Disc interference disorders are one Category of TMDs.
