Dental bite guards, also known as occlusal guards or night guards, are oral appliances worn over the teeth to protect them from grinding, clenching, or excessive forces during sleep or physical activity. These guards are custom-made to fit the individual’s mouth and provide a cushioning effect, preventing tooth damage, jaw pain, and headaches associated with bruxism (teeth grinding) or temporomandibular joint disorder (TMJD). They help distribute the forces evenly, reduce muscle tension, and provide a barrier between the upper and lower teeth.
