What Is Bruxism?

Bruxism is grinding of the teeth, typically accompanied by clenching of the jaw. It is caused by the activation of reflex chewing activity; it is not a learned habit.

Bruxism occurs to some extent in most humans. It often occurs during sleep and can even occur during short naps. Thirty to forty million Americans grind their teeth during sleep.

In most people, bruxism is mild enough not to be a health problem; however, some people suffer from significant bruxism that can become symptomatic.
