Abstract
The invention relates to oral compositions for combating dental caries. The compositions comprise a fluorine-containing anti-caries agent such as sodium fluoride or sodium monofluorophosphate and a particulate hydroxyapatite as abrasive. These ingredients are surprisingly compatible in that there is a reduced loss of available fluoride upon storage.
