Delivery system for an oral care substance using a strip of material having low flexural stiffness

A method of delivering an oral care substance to a surface of a tooth and its adjoining soft tissue, said method comprising the steps of:

• a. applying said substance onto said surface of said tooth and its adjoining soft tissue;
• 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;
• wherein said delivery system is substantially unnoticeable when worn.

A delivery system for an oral care substance, wherein said delivery system is substantially unnoticable 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 and its adjoining soft tissue when said delivery system is placed thereagainst;
• and
• b. an oral care substance applied to said strip of material such that when said delivery system is placed on a surface of said tooth and its adjoining soft tissue, 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 an oral care 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 and its adjoining soft tissue when said delivery system is placed thereagainst and said strip of material containing an array of shallow pockets;
• and
• b. an oral care substance applied to said strip of material such that when said delivery system is placed on a surface of said tooth and its adjoining soft tissue, 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 an oral care substance comprising:

• a. a strip of material made of polyethylene;
• and
• b. an oral care substance applied to said strip of material such that when said delivery system is placed on a surface of said tooth and its adjoining soft tissue, 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.
