主权项 1. An oral composition comprising: a first abrasive, wherein the first abrasive is selected from the group consisting of silica, alumina, calcium carbonate, and dicalcium phosphate; a water soluble film comprising a second abrasive, wherein the second abrasive is chosen from silica, silicon, silicate, aluminosilicate, bentonite, zeolite, kaolin, mica, alumina, calcium carbonate, cuttlebone, orthophosphate, polymetaphosphate, pyrophosphate, calcium hydrogen phosphate, calcium pyrophosphate, tricalcium phosphate, calcium metaphoshate, potassium metaphosphate, sodium metaphosphate, dicalcium orthophosphate, dicalcium, phosphate dihydrate, siliceous or diatomaceous earth, pumice, resin, melamine, phenolic resin, urea-formaldehyde resin, polycarbonate, boron carbide, silicon carbide, microcrystalline wax, microcrystalline cellulose and derivatives thereof; and a carrier; wherein the first abrasive is a cleaning abrasive having a Mohs hardness of about 1 to about 4, and the second abrasive is a polishing abrasive having a Mohs hardness of about 4 to about 9, and the second abrasive is present in an amount of 2% to 20% by weight of the composition; and wherein the first abrasive has a first particle size and the second abrasive has a seconds particle size, wherein the first particle size is greater than the second particle size wherein the first abrasive is present in an amount of about 1% to about 70% by weight of the composition; the second abrasive is present in an amount of about 5% to about 40% by it of the film; wherein the first abrasive has a hardness that is less than or equal to that of a target surface, and the second abrasive has a hardness of greater than or equal to that of the tar ret surface; and wherein the film comprises a polymer selected from the group consisting of cellulose ethers, acrylates, methacrylates, polyvinyl alcohol, polyalkylene oxides, polyvinylpyrrolidone, copolymers thereof and mixtures thereof.
