what is bruxism
Bruxism is the habit of clenching and grinding the teeth. It most often occurs at night during sleep, but it may also occur during the day. It is an unconscious behavior, perhaps performed to release anxiety, aggression, or anger.
Clenching or grinding of the teeth (bruxism) is a common activity that can occur both during the day and at night. Clenching or grinding (see Box to Right) while awake is especially common during periods of concentration, anger, or stress, and often occurs without a person being aware of it.
