An oral, tooth-treating composition which comprises 0.04 to 10% by weight of stannous fluoride and not less than 0.1% by weight of a phytic acid compound, the molar ratio of the phytic acid compound to stannous fluoride being in the range of from 0.01 : 1 to 4 : 1 and the composition being acidic, is effective in inhibiting dental caries and shows a prolonged effect after application. When a difficultly soluble stannous compound such as stannous pyrophosphate is further blended preferably so that a portion of the difficultly soluble stannous compound is in a precipitate form, the composition is good in storage stability. The oral composition may be used as dentifrices, mouthwashes, oral bands, topical solutions, cavity sealers, prophylactic pastes, dental flosses and the like. |
