The combination of the foregoing active ingredients is particularly effective against plaque when used in the compositions of the present invention. The compositions of the present invention include a dentifrice carrier containing at least 1 % by weight of a benzoic acid salt and detersive amounts of an oral surfactant. In a preferred embodiment of the present invention, a toothpaste formulation is provided, which has, as one of its active ingredients, at least about 6 % by weight of a benzoic acid salt. The carrier is any paste, or gel or the like capable of being applied to a toothbrush and brushed onto the teeth.
