Delivery system for a tooth whitener using a permanently deformable strip of material

A method of delivering a tooth whitening substance to a front surface of a tooth, said method comprising the steps of:

• a. applying said substance onto a conformable strip of material of sufficient length to cover a plurality of adjacent teeth having a yield point and thickness such that said strip of material substantially conforms to the curvature of the wearer's mouth, gaps between the adjacent teeth, and a shape of a tooth via permanent deformation under a pressure less than about 250,000 Pascals;
• and
• b. applying said conformable strip of material with said substance thereon to said surface such that said substance contacts said surface, said substance providing an active onto said surface, said substance also having sufficient viscosity and tackiness for providing adhesive attachment between said strip of material and said surface to hold said delivery system in place for a sufficient time to allow said active to act upon said surface, said substance having an extrusion resistance sufficient to withstand a normal force applied to deform said strip of material so that said substance is not substantially extruded from between said strip of material and said surface during manual deformation of said strip of material;
• wherein said conformable strip of material is unobtrusive so as to be wearable without interfering with normal social discourse and is of a size that individually fits an upper or lower row of a wearer's teeth when placed against the teeth.
