A composition of matter used to bleach the teeth and to protect the gingival tissues while bleaching the teeth. The composition is hydrogen peroxide in a concentration of 10 % to 35 % by weight in a solution and a mucoprotectant gel. The mucoprotectant gel is a composition of sodium stearate, cellulose emulsifier and water in varying proportions depending on the desired final composition. The composition of matter protects the mucous membranes of the mouth and more particularly the gingival tissues while bleaching the teeth with a concentration of hydrogen peroxide which would be caustic to the gingival tissues and mucous membranes if used without mucoprotectant. |
