A method of whitening teeth, including an application of functionalized calcium phosphate additives generated via a solid-state method. The additives were produced by placing predetermined amounts of inorganic and inorganic materials and milling media into a vessel rotatably connected to a turntable platform, an amount of an organic material into the vessel, rotating the vessel in a first direction while turning the turntable platform in a second direction counter to the first direction, with the resultant material defining the functionalized calcium phosphate. The inorganic material may include calcium phosphates of varying phases, structure, and composition. The organic material may include anionic surfactants, cationic surfactants, neutral surfactants, carboxylic acids, polymers, copolymers, block copolymers, and combinations thereof. Once produced, the additives were added to comestibles, such as in confectionery and foodstuff formats, for delivery to the teeth and dental structures.
