Abstract
Disclosed are methods of treating and protecting teeth against erosion by use of oral compositions comprising polymeric mineral surface active agents, metal ions such as stannous and zinc and combinations thereof. The present methods provide improved resistance of teeth to erosive demineralization or dissolution and prevention of tooth damage by subsequent exposure of teeth to erosive chemicals such as acidic foods and beverages.
Claims8
A method of protecting a subject's teeth from erosion comprising administering to the subject's oral cavity an oral care composition comprising a polymeric mineral surface-active agent selected from the group consisting of condensed phosphorylated polymers;
- polyphosphonates;
- polycarboxylates and carboxy-substituted polymers;
- copolymers of phosphate- or phosphonate-containing monomers or polymers with ethylenically unsaturated monomers, amino acids, or with other polymers selected from proteins, polypeptides, polysaccharides, poly(acrylate), poly(acrylamide), poly(methacrylate), poly(ethacrylate), poly(hydroxyalkylmethacrylate), poly(vinyl alcohol), poly(maleic anhydride), poly(maleate) poly(amide), poly(ethylene amine), poly(ethylene glycol), poly(propylene glycol), poly(vinyl acetate) or poly(vinyl benzyl chloride);
- and mixtures thereof, wherein said polymeric mineral surface-active agent is substantive to teeth and deposits a layer that protects teeth from erosive damage immediately after use of the oral composition and for a period of at least about one hour or longer thereafter.
A method of protecting a subject's teeth from erosion comprising administering to the subject's oral cavity an oral care composition having a pH of from greater than about 4.0 to about 10.0 and comprising a source of metal ions selected from the group consisting of stannous, zinc, copper, and mixtures thereof, wherein said metal ions form insoluble compounds or complexes that deposit on the tooth surface, thereby forming a film or coating that protects teeth from erosive damage immediately after use of the oral composition and for at least about one hour thereafter, and wherein the composition is essentially free of ethylenediaminetetracetates and phytates.
