Bruxism is the medical term for teeth grinding. Bruxism is reported by 8% of adults and, based on parent accounts, almost 14% of children grind their teeth a few times a week. Bruxism occurring during sleep has also been described as the grinding or clenching of teeth during sleep. It is also associated with episodes of tightening of the jaw. A plethora of consequences are associated with bruxism: wear and abrasion of teeth, headaches, oral and facial pain.
The diagnosis of this condition is based on a history of grinding reported by a third party (family member, friend), the presence of dental wear or damage, an increase in jaw muscle size and complaints of jaw and facial pin or fatigue upon waking.
