Abstract
A method by which a mucoprotectant gelatin which forms a protective coating on the mucous membranes of the mouth is provided for use with active ingredients for treating the teeth. The active ingredient may be an aqueous hydrogen peroxide solution or fluoride. When hydrogen peroxide is used as a bleaching agent the mucoprotectant prevents the caustic bleaching agent from damaging the gums. The bleaching agent and the mucoprotectant are stored in separate containers and are custom mixed by a supervising dentist and given to the patient in a dispenser so that the resulting slurry may be used in a personalized vacuformed mouthpiece. The treatment may last from several minutes to several hours.
