TOOTH BLEACHING AGENTS AND METHOD OF BLEACHING TEETH

摘要

A tooth bleaching agent comprising (a) titanium dioxide initiating photocatalytic action by irradiation with light, (b) a chemical compound generating hydrogen peroxide in aqueous solution, (c) an inorganic thickening agent or an organic thickening agent, (d) phosphoric acid and (d) condensed phosphate is proposed. A tooth bleaching method characterized by bleaching tooth by applying the breaching agent onto the surface of a tooth followed by irradiating the applied surface with light is also proposed. The tooth bleaching agent of the present invention and the bleaching method thereby show significant results such as (1) excellency in long-term storage and stability, (2) substantial improvement for workability on production and application, (3) easy application onto a tooth surface, (4) high safety assured by good bleaching results with low concentration of hydrogen peroxide, high bleaching results and the like
