A prefabricated oral device designed to protect the teeth, bones, and tissues of the mouth from damage due to impact/trauma typically during endoscopic diagnostic procedures, contact sports, and/or to prevent teeth grinding/clenching (bruxism). It is made of standard, preformed materials or items for adaptation to/direct insertion into the mouth; some types are referred to as nightguards or bite raising appliances. This is a reusable device.
