Delivery system for a tooth whitener using a strip of material having low flexural stiffness

The delivery system of claim 13 wherein the said tooth surface are not required to be prepared before application of said delivery system.

A method of delivering a tooth whitening substance to front side of a plurality of adjacent teeth, said method comprising the steps of:

• a. applying said substance onto a comfortable strip of material having a sufficient flexibility to form a curved shape around a plurality of adjacent teeth and said strip of material being readily conformable to tooth surfaces and to interstitial tooth spaces without permanent deformation;
• and
• b. applying said conformable strip of material with said substance thereon to said plurality of adjacent teeth without permanent deformation of said strip of material such that said substance contacts said surface, said substance providing an active onto said plurality of adjacent teeth, said substance also providing adhesive attachment between said strip of material and said plurality of adjacent teeth to hold said delivery system in place for a sufficient time to allow said active to act upon said surface.

A delivery system for delivering a tooth whitening substance to a plurality of adjacent teeth, said delivery system comprising:

• a. a strip of flexible material having a sufficient flexibility to form a curved shape on a plurality of adjacent teeth, said strip of material being readily conformable to tooth surfaces and to interstitial tooth spaces without permanent deformation when said delivery system is placed thereagainst and said strip of material containing an array of shallow pockets;
• and
• b. a tooth whitening substance applied to said strip of material such that when said delivery system is placed on a surface of said teeth, said substance contacts said surface providing an active onto said surface, said substance also 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.

A delivery system for delivering a tooth whitening substance to a plurality of adjacent teeth, said delivery system comprising:

• a. a strip of flexible material made of polyethylene;
• and
• b. a tooth whitening substance applied to said strip of material such that when said delivery system is placed on a surface of said teeth, said substance contacts said surface providing an active onto said surface, said substance also 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.
