Bite appliances are removable plastic devices made from impressions of your teeth. They are fitted to your teeth and balanced to relax the muscles and reduce body stress. Several adjustments must be made because the bite will change as the muscles relax. A daytime plate is generally worn on the lower teeth allowing ease of speech. A night guard is generally fitted for the upper teeth. This allows each arch of teeth to get periods of rest from the plate.
A night guard is a removable dental appliance designed to minimize the effect of bruxism (grinding) and other occlusal factors. Night guards are used while you are sleeping. If you grind your teeth at night, the night guard will protect your natural teeth and crowns from cracking or chipping.
