       6 . The method of  claim 1 , wherein the tooth bleaching gel comprises a flavor.  
   
   
       7 . The method of  claim 1 , wherein the tooth bleaching gel further comprises glycerin.  
   
   
       8 . The method of  claim 1 , wherein the flexible polymeric film has a thickness about 0.0013 mm.  
   
   
       9 . The method of  claim 1 , wherein the tooth bleaching gel is continuously coated along a longitudinal axis of the flexible polymeric film.  
   
   
       10 . The method of  claim 1 , wherein flexible polymeric film is provided as a single layer of polymer.  
   
   
       11 . The method of  claim 1 , wherein the tooth bleaching gel is homogenous.  
   
   
       12 . The method of  claim 1 , wherein the tooth bleaching gel has a viscosity between about 200 and about 1,000,000 cps.  
   
   
       13 . The method of  claim 1 , wherein the flexible polymeric film is sized to cover between 7 teeth and an entire row of teeth.  
   
   
       14 . The method of  claim 1 , wherein the overall thickness of the tooth bleaching product is less than about 1 mm.  
   
   
       15 . The method of  claim 1 , wherein  1 (a) to  1 (f) are repeated once a day for between about 7 and about 14 days.  
   
   
       16 . The method of  claim 15 , wherein each repetition of  1 (a) to  1 (f) uses a new flexible polymeric film.  
   
   
       17 . The method of  claim 1 , wherein the tooth bleaching gel is provided in the form of a stripe along the flexible polymeric film.  
   
   
       18 . The method of  claim 1 , wherein the flexible polymeric film is substantially flat prior to use.  
   
   
       19 . A system for bleaching a plurality of upper teeth, the teeth having facial, lingual, and incisal surfaces, comprising: 
 a) a plurality of tooth bleaching products, each tooth bleaching product comprising a substrate that receives a tooth whitening gel, wherein the substrate consists essentially of a flexible polymeric film that is sized to cover the facial, lingual, and incisal surfaces of a plurality of teeth, wherein the polymeric film adhesively attaches to the facial and lingual surfaces of the plurality of teeth during use and wherein the polymeric film is conformable to interstitial tooth spaces during use;    b) the tooth bleaching gel comprising a tooth bleaching active; and    c) wherein the system comprises a sufficient number of the tooth bleaching products to apply a new polymeric film once a day for between about 7 days and about 14 days.    
   
   
       20 . The system of  claim 18 , wherein the tooth bleaching active is hydrogen peroxide.  
   
   
       21 . The system of  claim 18 , wherein the tooth bleaching gel further comprises carboxypolymethylene.  
   
   
       22 . The system of  claim 18 , wherein the tooth bleaching gel further comprises between about 0% and about 40% water by weight of the tooth bleaching gel.  
   
   
       23 . The system of  claim 18 , wherein the tooth bleaching gel comprises a flavor.  
   
   
       24 . The system of  claim 18 , wherein the tooth bleaching gel further comprises glycerin.
