Patent ID: 7276229

Claim:
A method of reducing tooth erosion caused by acid in orally administered compositions comprising (i) providing a first acidic orally administrable composition; (ii) adding to said first acidic orally administrable composition: (a) a calcium compound present in an amount of 0.01 to 0.75 mol per mole of acid; (b) a viscosity modulating polymer material which is a polysaccharide selected from the group consisting of an alginate, locust bean gum, gellan gum, guar gum, gum arabic, tragacanth, carrageenin, acacia gum, xanthan gum, pectin, cellulose gum, or a combination or mixture thereof; and (c) controlling or adjusting the effective pH of the resulting composition to less than or equal to 4.5, and (iii) thereby providing a second acidic orally administrable composition which has a lower tooth erosion potential than said first acidic orally administrable composition; and (iv) orally administering said second acidic orally administrable composition to a mammal.
