  • Patent number: 5244651
    Abstract: A method of desensitizing hypersensitive dentin is disclosed. The method comprises treating teeth of patients suffering from hypersensitive dentin with a colloid produced by mixing (a) a salt of polyvalent metal and (b) a polyol phosphate and/or a water-soluble salt thereof. The colloid can constrict or occlude dentinal tubules in the tooth dentin, exhibiting a continuous effect on the desensitization of hypersensitive dentin owing to the very high absorptivity of the colloid to teeth. The colloid does not impair taste, and does not produce precipitate near the neutral region, enabling it to be used safely.
