A one-way fluoride releasing strip for preventing dental caries is provided to suppress washing fluorine away in the strip and prevent dental caries of infants. A fluoride releasing strip for preventing dental caries comprises a support layer and fluorine-containing layer on the support layer. The support layer contains hydrophobic polymer and additionally comprises 20-40 weight part of plasticizer based on the 100 weight part of hydrophobic polymer. The plasticizer is DBP(dibutyl phthalate) or DOP(dioctyl phthalate). The fluorine-containing layer contains drug carrier which is able to seal and release fluorine.
