Abstract
A system for delivering an oral care substance to the oral surface, the delivery system comprising a strip of flexible material having a sufficient flexibility to form to the contours of the oral surface. The strip of material is readily conformable to oral surfaces without permanent deformation when the delivery system is placed there against. The oral care substance is applied to the strip of material such that when the delivery system is placed on the oral surface the active contacts the surface. The oral care substance also provides adhesive attachment between the strip of material and the oral surface so as to hold the delivery system in place for a sufficient amount of time to allow the active to act upon the oral surface. Methods of delivering the oral care substance to the oral surface include pre-coating the strip of material, having the wearer apply oral care substance to the strip of material, or having the wearer apply the oral care substance directly to the oral surface and immediately applying the strip of material over the applied oral care substance.
