Bruxism or gnashing of teeth – is too strong, unconscious activity of the masseter muscle, clench of teeth, usually during sleep.

Apart from the night bruxism, there is diurnal bruxism when a person tends to involuntarily clench his teeth at the emotional tension.

A person, experiencing gnashing of teeth, can feel pain of jaw, cheek, pain in temple area, headache, the teeth become sensitive to cold, and while biting, teeth imprints may be visible on the tongue. During friction teeth wear out, become sensitive, fillings can chip off, some teeth, prostheses can crack or even break. Therefore bruxism is necessary to be treated.
