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.

Teeth whitening composition in the form of a chewing gum

Disclosed are compositions for bleaching teeth comprising at least two parts blended together before each application. The compositions offer extended shelf life and accelerated bleaching action while significantly reducing the possibility of user discomfort. In preferred embodiments, one part of the composition comprises peroxides of monovalent or bivalent metals such as sodium, potassium, magnesium, calcium, strontium, and zinc, and another part comprises an aqueous solution of one or more acids able to convert said metal peroxides into hydrogen peroxide, such reaction occurring under conditions resulting in the acceleration of the generation of radical oxygen and, consequently, the teeth whitening process. The inventive compositions allow for adequate water in the composition to avoid tissue desiccation and associated user discomfort without compromising the shelf life of the composition.
