Abstract: A dentifrice composition is disclosed comprising a soluble calcium sequestering agent that is not an oxidizing agent, wherein the composition has an RDA value of below 30 and an IVSR value greater than 50 (when compared to a Control) and an orally acceptable vehicle, wherein the calcium sequestering agent is present in a proportion of 1-20 wt % and an abrasive is present in a proportion of 0-5 wt % of the composition. The composition is highly effective in removing stains from natural teeth and prosthetics and will not damage the tooth or prosthetic due to excessive abrasion.

Abstract: A dentifrice composition comprising an abrasive system comprising a combination of a crystalline aluminosilicate having an average crystallite size below 1.0 ?m and a water-soluble, orally acceptable calcium sequestering agent plus an orally acceptable carrier. The crystalline aluminosilicate may have an RDA of less than 120 and a calcium binding capacity of at least 100 mg CaO per gram of anhydrous aluminosilicate. The water-soluble, orally acceptable calcium sequestering agent may be sodium tripolyphosphate.

Abstract: A dentifrice composition comprising an abrasive system comprising at least one abrasive silica which may be selected from a first silica having a Radioactive Dental Abrasion (RDA) in the range 30 to 150 and a second silica an RDA in the range 100 to 300, and a crystalline aluminosilicate having an average crystallite size below 0.2 ?m plus an orally acceptable carrier. The content by weight of the first silica being greater than that of the second silica and the RDA of the second silica being greater than that of first silica.
