Abstract
A two-component dental bleaching system is provided wherein the components are adapted to be admixed and applied to the teeth from a dental bleaching tray. One component comprises a dental peroxide gel having a pH from about 4 to about 7 and the other component comprises an orally compatible alkaline gel having a pH from about 9 to about 13. The admixing of the components provides a dental bleaching gel having a pH from about 8.5 to about 11 to thereby increase the rate of release of active oxygen and accelerate the bleaching action.
