A new tooth whitening composition provides sustained release of high levels of whitening agent and is moisture-activated without significant swelling. A preferred system for applying the composition to the teeth is flexible, self-adhesive, and well-tolerated by users. In certain embodiments the tooth whitening composition comprises a mixture of tooth whitening agents, with a first whitening agent selected so as to release peroxide gradually upon contact with moisture and produce an alkaline pH, and a second whitening agent selected so as to release peroxide rapidly upon contact with moisture.

This invention relates to the use of hydrophilic, biocompatible adhesives in drug delivery systems, wound dressings, bioelectrodes, and other systems in which hydrophilic, biocompatible adhesives are desirable. In particular, the invention relates to water-swellable, water-insoluble polymers that in combination render a composition adhesive upon contact with moisture, wherein a first water-swellable, water-insoluble polymer is cationic, a second water-swellable, water-insoluble polymer is anionic, and the polymers are ionically associated with each other to form a polymer matrix.
