A professional biteguard also known as an occlusal guard is a removable appliance. A Biteguard helps prevent teeth enamel from wearing down due to teeth grinding. The appliance is worn at night and protects the enamel at night when most teeth grinding takes place. There are non-professional ones available in the stores. These so called home made versions are ill-fitting. I’ve seen patients buy these and they don’t fit properly and have damaged the enamel on their teeth from wearing them. I strongly urge anyone that needs an Biteguard to seek a dentist to have a professional one made. The fee should be around $350.
