Delivery system for an oral care substance

Abstract

A tooth whitening substance formed into a thin layer is provided. The tooth whitening substance includes a polyox resin and a tooth whitening active. The polyox resin adheres the thin layer to a plurality of teeth for a sufficient time to allow the tooth whitening active to act upon the plurality of teeth.

1 . An oral care delivery system comprising: 
 (a) a strip of material;    (b) an oral care composition; wherein said oral care composition comprises a tooth bleaching agent and fluoride;    (c) wherein said delivery system is applied to the surfaces of a plurality of teeth and wherein the overall thickness of said oral care delivery system is less than about 1 mm.    
   
   
       2 . The oral care delivery system of  claim 1 , wherein said oral composition is a stripe on said strip of material.  
   
   
       3 . The oral care delivery system of  claim 1 , wherein said oral care composition further comprises water.  
   
   
       4 . The oral care delivery system of  claim 1 , wherein said tooth whitening composition is a peroxide.  
   
   
       5 . The oral care delivery system of  claim 1 , wherein said oral care composition further comprises carboxypolymethylene.  
   
   
       6 . The oral care delivery system of  claim 1 , wherein said oral care composition further comprises glycerin.  
   
   
       7 . The oral care delivery system of  claim 1 , wherein said strip of material is flexible.  
   
   
       8 . The oral care delivery system of  claim 1 , wherein said strip of material is polyethylene.  
   
   
       9 . The oral care delivery system of  claim 1 , wherein said strip of material is sized to cover a front surface of a plurality of teeth.  
   
   
       10 . An oral care delivery system comprising: 
 (a) a flexible strip of material;    (b) an oral care composition; wherein said oral care composition comprises hydrogen peroxide, and phosphate;    (c) wherein said delivery system is applied to the front, incisal edge and lingual surfaces of a plurality of teeth.    (d) wherein the overall thickness of said oral care delivery system is less than about 1 mm.    
   
   
       11 . The oral care delivery system of  claim 10 , wherein the oral care composition has a viscosity between about 200 and about 1,000,000 cps.  
   
   
       12 . The oral care delivery system of  claim 10 , wherein said flexible strip of material is a flexible polymeric film.  
   
   
       13 . The oral care delivery system of  claim 11 , wherein said flexible polymeric film is sized to cover to cover between 7 teeth and an entire row of teeth.  
   
   
       14 . The oral care delivery system of  claim 10 , wherein said oral care composition further comprises carboxypolymethylene.  
   
   
       15 . A method of treating a plurality of teeth, the teeth having facial, lingual, and incisal surfaces, comprising: 
 a) adhesively attaching an oral care product comprising a flexible polymeric film and an oral care composition to the facial, incisal edge and lingual surfaces of a plurality of teeth, wherein the oral care composition is pre-applied to the polymeric film and comprises a peroxide, carboxypolymethylene, and fluoride and wherein the oral care composition is applied as a stripe to the polymeric film;    b) conforming the flexible polymeric film to the surfaces of the plurality of teeth;    c) peeling the flexible polymeric film from the plurality of teeth;    d) repeating steps (a) through (d), wherein each repetition utilizes a new tooth bleaching product;    wherein the tooth bleaching product has a thickness of less than 1 mm.    
   
   
       16 . The method of  claim 15 , wherein the polymeric film has a texture.  
   
   
       17 . The method of  claim 15 , wherein the oral care product is transparent.  
   
   
       18 . The method of  claim 15 , wherein the oral care product has a flexural stiffness of less than about 3 grams/cm.
