The present invention relates to oral care compositions comprising stannous ions, a mint-type flavor oil, a protectant component that prevents generation of off odor and off taste in the composition, and orally acceptable carriers. The mint-type oils include peppermint, spearmint and corn mint. Suitable protectant components include copper salts and carbonyl compounds such as ascorbic acid； cis-jasmone； 2,5-dimethyl-4-hydroxy-3(2H)-furanone； 5-ethyl-3-hydroxy-4-methyl-2(5H)-furanone； vanillin； ethyl vanillin； anisaldehyde； 3,4-methylenedioxybenzaldehyde； 3,4-dimethoxybenzaldehyde； 4-hydroxybenzaldehyde； 2-methyoxybenzaldehyde； 4-methoxybenzaldehyde； benzaldehyde； cinnamaldehyde (3-phenyl-2-propenal)； hexyl cinnamaldehyde； &alpha；-methyl cinnamaldehyde； ortho-methoxy cinnamaldehyde； &alpha；-amyl cinnamaldehyde； and combinations thereof. The oral care composition may be a dentifrice.
