TMJ is a term used to describe the temporo-mandibular joint, which connects the mandible (jawbone) to the skull. It allows you to move your jaw up and down and from side to side, so that you can talk, chew, and yawn.

Grinding and clenching your teeth is a widespread and an unpleasant problem. It may sound relatively harmless, but continually grinding and gnashing your teeth, may become a habit which can lead to long-term damage to your teeth. The medical name for this condition is known as Bruxism, and unfortunately many people do not even seem to realise that they have the condition.
