PROBLEM TO BE SOLVED: To obtain a dental/oral composition capable of preventing and curing dental diseases such as dental caries, periodontal diseases (pyrorrhea alveolaris, etc.), diseases of oral cavity and the like and effective for preventing color changes of teeth and dental materials, bleaching of discolored teeth, removing bad breaths and provide a method for the same. SOLUTION: This dental/oral composition contains a photocatalytic titanium oxide or its precursor; at least one species selected from a silicon compound such as a tetraalkoxysilane and the like, a silicone resin or its precursor; and a liquid medium or the phtocatalytic titanium oxide or its precursor and the liquid medium. This method for fixing the photocatalytic titanium oxide or forming its film to coat the dental/oral composition on teeth, gingiva, oral membrane and dental materials in the oral cavity or coating on the dental materials out of the oral cavity. |
