Abstract
A delivery system for controlled administration of a dentin-hypersensitivity-ameliorating composition to targeted areas is described. In particular, a bio-compatible delivery vehicle is described which contains unreacted, reactive materials dispersed therein. These materials form a dentin-hypersensitivity-ameliorating composition when reacted. Furthermore, these materials are separately encapsulated within protective encapsulating matrices to prevent the reaction thereof until delivery of the materials to a dentinal surface.
