Abstract: A method and system for whitening teeth using at least a whitening gel, a whitening toothpaste, and a whitening rinse. Preferably the system employs a predetermined weight percentage of a peroxide based bleaching agent to effect tooth whitening. In certain formulations the components may use carbamide peroxide or hydrogen peroxide as a bleaching agent. The system may be used at home and preferably does not require clinical visits. The method includes the steps of brushing the teeth daily and before each bleaching with a whitening toothpaste, bleaching the teeth with a whitening gel twice daily, and rinsing with a whitening rinse. Daily brushing with a whitening toothpaste and preferably rinsing with a whitening rinse follow these whitening treatments. A system or kit for whitening teeth includes all of the components necessary to follow the aforementioned method, including a whitening gel, whitening toothpaste, a whitening rinse, and one or more mouth guard trays.
