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.
