1. In a dental treatment system that includes a moisture-resistant barrier layer adapted to be placed upon and worn over a treatment composition used in treating a person's teeth, an article of manufacture comprising:
a substantial dry adhesive activation composition that is sufficiently solid so that it will substantially maintain either a tray-like or a strip-like configuration so as to be adapted for handling and application to a patient's teeth either with or independent of the barrier layer, and the adhesive activation composition having increased adhesiveness to teeth when moistened by saliva or water and, comprising at least one tooth adhesion agent that at least partially contributes to said increased adhesiveness to teeth and at least one bleaching agent activator; and
a substantially viscous and tacky dental bleaching gel, adjacent to said adhesive activation composition, comprising at least one dental bleaching agent, at least one tackifying agent, and a liquid or gel carrier.
