Method and device for teeth whitening using a dry type adhesive

Abstract

A dry type adhesive device for teeth whitening in which a peroxide tooth whitening agent is stabilized is disclosed. The dry type adhesive device for tooth whitening comprises a matrix type adhesive layer and a backing layer wherein the adhesive layer contains a peroxide as a teeth whitening agent and a hydrophilic glassy polymer as a base polymer so that the hydrophilic glassy polymer provides strong adhesion to teeth when hydrated at the enamel layer of the teeth in the moist oral cavity and the whitening agent is released. In particular, although the dry type adhesive device is touched with the hands or contact the skin during attaching to the teeth prior to hydration, no stickiness and releasing of the whitening agent takes place, thus being safe. In addition, since the dry type patch has strong adhesive strength to the teeth and excellent adhesion maintenance after being hydrated and attached to the teeth, it can remain attached to the teeth for a long time and thus exhibits excellent whitening effect even low concentrations of a whitening agent. Furthermore, the dry type adhesive device can provide excellent whitening within a short period of time.
