elmex toothpaste children from 2nd to 6th birthday : elmex children toothpaste was developed for the special caries protection of baby teeth. It contains the unique amine fluoride for a triple protection mechanism: the toothpaste forms a calcium fluoride topcoat on the enamel and makes the teeth more resistant to caries-related mineral degradation. In addition, it helps to reintegrate the caries released minerals in the enamel.
