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

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

• a. applying said substance onto a comfortable 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;
• and
• b. applying said conformable strip of material with said substance thereon to said surface without permanent deformation of said strip of material such that said substance contacts said surface, said substance 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 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 said surface of said tooth;
• b. applying a conformable 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, over said substance on said surface permanent deformation of said strip of material, said substance 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 a tooth whitening substance, wherein the delivery system is substantially transparent and is almost unnoticeable when worn, comprising:

• a. a strip of material having a flexural stiffness less than about 0.6 grams/centimeter as measured on a Handle-O-Meter per ASTM test method D2923-95, said strip of material being readily conformable without permanent deformation to a shape of a tooth when said delivery system is place thereagainst;
• and
• b. a tooth whitening substance applied to said strip of material such that when said delivery system is placed on a front surface of said tooth, 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 a tooth whitening substance comprising:

• a. 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, said strip of material being readily conformable without permanent deformation to a shape of a tooth 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 tooth, 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 a tooth whitening substance comprising:

• a. a strip of 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 tooth, said substance contacts said surface providing an active onto said surface, said substance also providing adhesive attachment between said strip of material on a said surface to hold said delivery system in place for a sufficient time to allow said active to act upon said surface.
