Can't stop clenching my teeth. how do i break this habit?

Teeth clenching: This is usually involuntary and often done during sleep when it can do a lot of damage to the teeth and jaw. The solution is a professionally fabricated night guard appliance which prevents clenching and grinding. If you find yourself doing it during the day, you need to become aware of things that are causing you to be stress and clench and try and avoid those situations.
