Abstract
Described herein is a novel teeth whitening chewing gum formulation comprising bivalent metal peroxide(s) and anhydrous organic acids. Upon mastication in the oral environment, the acids react with the peroxide to form hydrogen peroxide in situ, in an environment stimulating the decomposition of such peroxide to form water and radical oxygen. The system is characterized by its efficacy and convenience. The teeth whitening composition of the preferred embodiment is also virtually insensitive to storage conditions, allowing for an extended shelf life.
