Abstract A three component system and method for whitening teeth. The first component is a pre-conditioning mouth rinse comprised of a dilute aqueous solution of acetic acid and N-L-alpha- aspartyl-L-phenylalanine methyl ester. This component cleanses the pellicle film on the user's teeth and improves the uptake of molecular oxygen by the enamel from the second component which comprises a bleaching gel including hydrogen peroxide. The preferred concentration of hydrogen peroxide is approximately six percent. The third component is a polishing and pigmenting cream or paste that includes an abrasive substance and a pigmenting agent. The abrasive agent is preferably an alumina silicate and the pigmenting agent is preferably titanium dioxide particles.
