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