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.
