Oral care product

Abstract

An oral care product comprising a first composition comprising an insoluble calcium salt that is not a calcium phosphate salt, a second independent composition comprising a source of phosphate ions, and a means for delivering each of the compositions to the surface of the teeth.

1 . An oral care product comprising a first composition comprising an insoluble calcium salt that is not a calcium phosphate salt, a second independent composition comprising a source of phosphate ions, and a means for delivering each of the compositions to the surface of the teeth. 
   
   
       2 . An oral care product according to  claim 1 , wherein the insoluble calcium salt is a calcium silicate. 
   
   
       3 . An oral care product according to  claim 2 , wherein the calcium silicate has a Ca:Si ratio of from 1:3 to 3:1. 
   
   
       4 . An oral care product according to  claim 1 , wherein the insoluble calcium salt is a bio-material. 
   
   
       5 . An oral care product according to  claim 1 , wherein the insoluble calcium salt is mesoporous. 
   
   
       6 . An oral care product according to  claim 5 , wherein the mesoporous calcium salt has an average pore size (diameter) of preferably from 0.4 to 4 nm. 
   
   
       7 . An oral care product according to  claim 1 , wherein the insoluble calcium salt is present in the first composition at from 5 to 20% by weight of said composition. 
   
   
       8 . An oral care product according to  claim 1 , wherein the first composition comprises less 0.1% by weight of phosphate ions. 
   
   
       9 . An oral care product according to  claim 1 , wherein the first composition has a pH of from 8.5 to 10. 
   
   
       10 . An oral care product according to  claim 1 , wherein the source of phosphate ions is a water-soluble salt. 
   
   
       11 . An oral care product according to  claim 1 , wherein one or more of the compositions is applied as a gel treatment. 
   
   
       12 . An oral care product according to  claim 1 , wherein the means of delivery involves a dual tube having a first compartment for the first composition and a second, independent compartment for the second composition. 
   
   
       13 . An oral care product according to  claim 1 , wherein the means of delivery involves a tape, in particular an adhesive tape, onto which one or preferably both of the compositions are applied, prior to the strip being placed in contact with the teeth. 
   
   
       14 . An oral care product according to  claim 1 , wherein the means of delivery involves a single tube having the first composition and second composition present as independent compositions within the same tube. 
   
   
       15 . An oral care product according to  claim 14 , wherein the quantity of water within each of the compositions is less than 30% by weight. 
   
   
       16 . An oral care product according to  claim 15 , wherein the first composition has less than 20% by weight of water and the second composition has less than 25% by weight of water. 
   
   
       17 . A method of remineralising and/or whitening the teeth comprising the steps of treating the teeth with a first composition comprising an insoluble calcium salt that is not a calcium phosphate salt and a second independent composition comprising a source of phosphate ions. 
   
   
       18 . A product comprising a first composition comprising an insoluble calcium salt that is not a calcium phosphate salt in combination with a second independent composition comprising a source of phosphate ions for use as a medicament. 
   
   
       19 . The use of a first composition comprising an insoluble calcium salt that is not a calcium phosphate salt in combination with a second independent composition comprising a source of phosphate ions for the manufacture of an oral care product. 
   
   
       20 . The use according to  claim 19  for the whitening of teeth. 
   
   
       21 . The use according to  claim 19  for the treatment of dental erosion. 
   
   
       22 . The use according to  claim 19  for the treatment of tooth decay. 
   
   
       23 . The use according to  claim 19  for the treatment of sensitive teeth.
