A dental composition, such as a paste or gel dentifrice containing triclosan, as an antibacterial agent which acts to decrease plaque on the teeth, and polyphosphate for anti-tartar actions, is packaged in a finger actuatable pump-type plastic dispensing container which is made of or includes a solid poly- meric material, such as a polyfluoroethylene, which is compatible with triclosan, so that excessive loss of its anti-plaque activity on storage is avoided, which losses have been noted when various other plastics have been employed as dispensing container component materials. Alternatively, others of such plastics may be employed for dispensing container parts when a stabilizer, such as a terpene, e.g., limonene, is present in the dentifrice. The dentifrice preferably also contains a tooth hardening propo- tion of a source of fluoride ions, a stabilizing proportion (in conjunction with the fluoride source) for the polyphosphate, of a polyvinyl methyl ether-maleic anhydride copolymer, and normal dentifrice adjuvants.
