摘要： A method for strengthened porcelain tooth is disclosed, which comprises depositing one or more inorganic salts of metals selected from rubidium, cesium, and potassium on the surface of a porcelain tooth obtained by sintering a dental porcelain material containing feldspar as a main raw material and sodium, and heat treating the porcelain tooth at temperature of 380.degree. C. or higher but lower than the melting point of the inorganic salt and the strain temperature of the porcelain tooth. According to the method of this invention, the porcelain tooth can be strengthened with ease while maintaining translucency and color tone as in a natural tooth, without using any special device.
