Chronic bruxism in individuals may lead to fracture in dental fillings. Constant rubbing and clenching of teeth also leads to attrition with exposure of the dentine leading to sensitivity. Severe chronic teeth grinding may also cause headaches, facial pain and is a primary cause of dysfunction of the jaws.
