is the habit or teeth grinding, or clenching or thrusting the jaw forward. Dentists play a pivotal role in diagnosing and managing patients with bruxism. Bruxism can cause damage to the teeth, such tooth wear, broken restorations, chipped teeth and also cause tooth pain. In addition, bruxism can also damage the tissues supporting the teeth and cause pain to the joints.1
