<p>New oral hygiene compositions comprise dissolved monofluorophosphate, carbonate and metasilicate ions, substantially free of alumina, in proportions sufficient to produce a solution in the mouth containing from 4 to 8 x 10-2 mol.1-1 monofluorophosphate, 2 x 10-4 to 4 x 10-3 mol.1-1 carbonate and from 1.5 to 3 x 10-3 mol.1-1 metasilicate ions. Such compositions, which may be presented as toothpastes, give enhanced fluoride release, compared with known similar compositions lacking metasilicate ions, and thus give improved protection against dental caries.</p> |
