Abstract
A method for inhibiting dentinal hypersensitivity by applying a dentinal hypersensitivity inhibitor on a dentin surface. The dentinal hypersensitivity inhibitor contains at least one tetracalcium phosphate particle, an alkali metal salt of phosphoric acid, and at least one acidic calcium phosphate particle. The tetracalcium phosphate particle has an average particle diameter of 0.5 to 40 μm. The dentinal hypersensitivity inhibitor contains a blended amount of the tetracalcium phosphate particle of 5 to 55 parts by weight relative to 100 parts by weight of a whole amount of the dentinal hypersensitivity inhibitor and a blended amount of the alkali metal salt of phosphoric acid of 1 to 100 parts by weight relative to 100 parts by weight of the tetracalcium phosphate particle.
