Teeth Grinding
Over time Bruxism, or teeth-grinding, can wear down or fracture the enamel due to constant clenching. Bruxism can also ground down the upper and lower front teeth. Generally Bruxism is often worst when you sleep that is when you ca not control it. Reducing stress may help. Some people wear a special mouth guard to bed. Ask your dentist if this is a problem. You can buy the guards in a drugstore or discount store, or your dentist may make you a custom model.
