Solid or semi-solid acidic oral compositions having reduced tooth erosion characteristics are prepared by adding a calcium compound to an acid composition so that the mol ratio of calcium to acid ranges from 0.3 to 0.8, and the effective pH of the composition, if necessary after adjustment with an alkali, is from 3.5 to 4.5.

La présente invention a trait à des compositions orales solides ou semi-solides possédant des propriétés d'inhibition de l'érosion des dents. On obtient ces compositions en ajoutant à une composition d'acide un composé de calcium de manière à ce que le rapport molaire entre le calcium et l'acide se situe entre 0,3 et 0,8 et que le pH utile de la composition (corrigé si nécessaire avec un alcali) soit compris entre 3,5 et 4,5.
