Abstract: A delivery system for an oral care substance includes a strip of material having a flexural stiffness less than about 50 grams/centimeter as measured on a Handle-O-Meter per ASTM test method D2923-95. The strip of material is readily conformable without permanent deformation to a shape of a tooth and its adjoining soft tissue when the delivery system is placed thereagainst. The delivery system also includes an oral care substance applied to the strip of material such that when the delivery system is placed on a surface of the tooth and its adjoining soft tissue, the substance contacts the surface providing an active onto the surface. The substance also provides adhesive attachment between the strip of material and the surface to hold the delivery system in place for a sufficient time to allow the active to act upon the surface.

Abstract: A delivery system for a tooth whitening substance includes a strip of material having a flexural stiffness less than about 50 grams/centimeter as measured on a Handle-O-Meter per ASTM test method D2923-95. The strip of material is readily conformable without permanent deformation to a shape of a tooth when the delivery system is placed thereagainst. The tooth whitening substance is applied to the strip of material such that when the delivery system is placed on a surface of the tooth, the substance contacts the surface providing an active onto the surface. The substance also provides adhesive attachment between the strip of material and the surface to hold the delivery system in place for a sufficient time to allow the active to act upon the surface. A method of delivery includes pre-coating the strip of material, having the wearer apply substance to the strip of material, or having the wearer apply the substance directly to the surface before applying a strip of material.
