ABSTRACT:
A delivery system for an oral care substance includes a strip of material having a yield point and thickness such that the strip of material substantially conforms to a shape of a tooth and its adjoining soft tissue via permanent deformation under a pressure less than about 250,000 Pascals 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. The substance has an extrusion resistance sufficient to withstand a normal force applied to deform the strip of material so that the substance is not substantially extruded from between the strip of material and the surface during manual deformation of the strip of material. 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.
