A conventional toothpaste is dispensed on a toothbrush along with a quantity of an abrasive free dentifrice containing hydrogen peroxide as an active constituent. Abrasion constituents of the conventional toothpaste interact with the hydrogen peroxide constituent of the dentifrice to accelerate the breakdown of the hydrogen peroxide constituent and the release of active oxygen. The employment of corn starch as a base for the hydrogen peroxide dentifrice also results in a significant reduction in dentin abrasion levels as compared with the conventional toothpaste alone.
