Abstract
An oral composition for removing tooth stains, such as those caused by an association of a chromogen with a layer of proteinaceous acquired pellicle on a tooth surface is provided. The composition includes (i) a destabilizing agent to disassociate and solubilize the chromogen from the layer of proteinaceous acquired pellicle, and (ii) a complexing agent having affinity for the disassociated chromogen to prevent its reassociation with the layer of proteinaceous acquired pellicle. The oral care composition is formulated to provide an oral pH equal to or above a pH for destabilizing the chromogen from its bond to the proteinaceous acquired pellicle, but less than a pH which can destabilize the chromogen from its bond to the complexing agent.
