Disclosed method involves contacting a dental surface with zinc phosphate, wherein zinc phosphate is presented in an oral care composition containing an orally acceptable carrier. After contact of tooth surface with zinc phosphate, surface of tooth is exposed to material causing chemical staining. Chemical staining caused by such exposure is inhibited by bringing the tooth surface into contact with zinc phosphate. Oral care composition contains zinc phosphate in amount of 1 wt % to 5 wt % of the total weight of the composition.
