A biteguard is a custom-made, clear, acrylic appliance that is usually worn on the upper teeth. These appliances protect the teeth and any restorations.
By absorbing forces from clenching and grinding of the teeth, a biteguard can prevent wear and damage. In addition, it can often have a relaxing effect on the jaw, muscles, and joints.
Biteguards are typically worn at night, but they can be worn during any stressful times when clenching or grinding may occur.
