A dentifrice composition is disclosed comprising a soluble calcium sequestering agent that is not an oxidising agent, wherein the soluble calcium sequestering agent is a polymeric material comprising a phosphonate group. 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. The compositions are also useful for combating the problems associated with acid erosion and/or tooth wear.
