摘要： PROBLEM TO BE SOLVED: To provide a bleaching agent set for teeth by solving a problem such that when titanium oxide powder having a photocatalytic activity and blended by 5 wt.% in conventional bleaching agents for the teeth is excited by light from outside, the light hardly reaches to the titanium oxide, etc., staying on the teeth to exhibit the bleaching effect caused by light shading effect which the titanium oxide has by itself, and a method for bleaching the teeth.
SOLUTION: This method for bleaching the teeth is provided by using the bleaching agent set for the teeth constituted by a first component consisting of an organic solvent containing at least one kind of powder having the photocatalytic activity selected from titanium oxide, titanium nitroxide and titanium oxide doped with nitrogen and preferably further containing at least one kind of a metal oxide, a metal salt and metal powder, a thickening agent and water, and a second component consisting of a compound generating hydrogen peroxide in water, a thickening agent and a carrier, first attaching the first component on the surface of the teeth, then bringing the second component into contact with the surface of the teeth to be irradiated with the light and bleach the teeth.
