Mouthguard

If you grind or clench your teeth at night, a nightguard (also called an occlusal guard or bruxism appliance) is one of the best tools your dentist can give you. It protects your enamel, cushions your jaw joints, and can prevent the kind of tooth damage that leads to crowns, root canals, or worse. But here is the thing most people overlook: a nightguard you do not clean regularly can cause its own problems.
