A nightguard, can be made by a dentist to alleviate signs and symptoms of tooth grinding. A thin layer of plastic (hard or soft) is molded to fit snugly over the teeth, similar to a sports mouthguard. This appliance can be worn during the day or while you sleep.

Nightguards help protect your teeth and any dental work, such as fillings and crowns, from wearing down or even fracturing.

The nightguard can also help relieve excess pressure on the jaw joint and prevent damage to it. The appliance, also referred to as an occlusal splint, helps reduce pressure to the teeth and prevent damage to the gums and bone surrounding the teeth.
