PROBLEM TO BE SOLVED: To provide a teeth bleaching material able to more safely express effect in a shorter time than conventional one without using a specific instrument and easily applied to treatments, a method for producing the teeth bleaching material and a mount for bleaching teeth.SOLUTION: The teeth bleaching material comprises a fine powdery high molecular compound imparted with ability for generating active oxygen. As an ingredient for imparting the ability for generating active oxygen, either one of hydrogen peroxide, urea peroxide, a perborate, a percarbonate, a perphosphate, a persulfate, calcium peroxide or magnesium peroxide is used. The mount for bleaching teeth is prepared by blending a high molecular resin with the teeth bleaching material prepared by mixing the high molecular compound with the ingredient imparting the ability for generating active oxygen, drying and pulverizing the mixture to be the fine powdery material, and molding the blend.COPYRIGHT: (C)2008,JPO&INPIT【課題】活性酸素発生能を有する成分を固形化することにより、従来技術よりも安全で、短時間で効果を発揮でき、かつ特別な器械は不要で、治療が容易である歯牙漂白剤、歯牙漂白剤の製法及び歯牙漂白用装着体を提供する。【解決手段】歯牙漂白剤は、活性酸素発生能を付与した高分子化合物の微粉体からなる。活性酸素発生能を付与する成分には、過酸化水素、過酸化尿素、過ホウ酸塩、過炭酸塩、可憐酸塩、過硫塩素類、過酸化カルシウム、過酸化マグネシウムのいずれかを用いる。歯牙漂白用装着体は、活性酸素発生能を付与する成分と高分子化合物を混和して乾燥し、微粉化して生成した歯牙漂白剤と高分子樹脂とを混和して成形する。【選択図】なし
