What does it mean when the jaw clicks?

TMJ: May be tmj. Your dentist can help.

TMJ motion: The jaw joint called the TMJ can make noise as it moves, if not painful or associated with headaches it brobably means nothing.

Jaw clicking : This could be normal. Sometimes it could be from temporal mandibular joint arthritis.

TMJ dysfunction: Is not always the case with isolated jaw "pops" and "clicks". The noise is usually a result of the fibrocartilagenous articular disc being anteriorly positioned and when the joint translates, during a phase of this translation (opening or closing) the disc "pops".

Displaced disk: Displaced disk in jaw joint (TMJ). May not be a problem if not accompanied by jaw pain, limited oral opening, chewing problems, head or ear ache. If you clench and grind your teeth, or have these other TMJ symptoms, see a TMJ expert.
