A Night Guard is a dental appliance that is worn at night and is designed to protect your teeth from damage caused by grinding or clenching when sleeping. Night guards will not prevent the habits of grinding or clenching, but when fitted over the teeth they provide a surface that prevents the grinding or clenching from destroying the teeth. Night guards are recommend to protect your own teeth or the dental restorations within your mouth. Night guards can also improve symptoms related to TMD (Temporomandibular Joint Dysfunction)
