Abstract
A dental bleaching gel composition having a long shelf life for use with an activator system to cause accelerated bleaching action of a peroxide bleaching agent in the bleaching gel composition when applied upon a tooth surface and to a method for applying and activating a dental bleaching gel upon a tooth surface for cosmetically whitening the tooth and/or for the treatment of stains or discolorations over a shortened time period. The dental bleaching gel has a pH independent thickening agent, a stabilizing agent for the peroxide bleaching agent and a FD & C approved dye. The activator system comprises an activator for accelerating the bleaching action of the peroxide bleaching agent and an applicator for storing the activator in a dry form separated from the bleaching gel composition such that upon contacting the applicator to the bleaching gel composition the peroxide bleaching agent contained in the gel is activated with the applicator being used to substantially simultaneously apply the bleaching gel to the tooth or teeth to be bleached.
