Abstract: Dental erosion is a universal oral disease， and the incidence of dental erosion is increasing year by year according to the improvement of living standard. Hydroxyapatite dissolution reaction will happen when enamel is in acidic conditions；the calcium phosphate salts， which is dissolved from enamel，can spread out on the teeth surface，and this process is called demineralization .Once demineralization occurs， which often affect the health and aesthetic of teeth，it mostly can not be reversed. The control of dental erosion has got the hotspot of research both at home and abroad in the last few years. Researchers have affached great importance to stannous fluoride’s protective effect on teeth. The mechanism of the control of dental erosion and the impact factors of experimental study to verify the effectiveness were reviewed as follows.

Key words: dental erosion, demineralization, stannous fluoride
