Bruxism is the repetitive grinding or clenching of teeth. There are two distinct types of bruxism: sleep bruxism and awake bruxism. Awake bruxism is believed to be more common and usually consists primarily of teeth clenching without grinding. More than 80% of people with sleep bruxism may not realize they grind their teeth during sleep.
