Night guards is a removable appliance placed on top of the teeth which acts like a barrier, to protect them from wear and tear. It helps to reduce the impact of clenching and grinding during sleep.
Grinding refers to the movement of the jaw back and forth, while clenching refers to the movement of biting down with pressure for an extended period of time. However, many people are unaware that they even have the disorder because it often occurs at night during sleep.
During these movements, teeth could lose their protective outer layer, which is called the Enamel. Enamel cannot be replaced once it's lost, and the loss of Enamel can cause hypersensitivity to hot and cold food/beverages.
Over time, it can lead to damaged/broken teeth, jaw disorders, periodontal disease, bone loss and headaches.
