Why does Kinder Karex not contain fluoride?
Especially for children under the age of 6, the addition of fluoride to toothpaste is a subject of much debate. Children in particular swallow a lot of the toothpaste. However, the intake of other sources of fluoride (vitamin D preparations with fluoride, fluoride salt etc.) considerably increases the risk of fluorosis (discoloration of the teeth due to an elevated intake of fluoride). The Federal Institute for Risk Assessment states that when children's toothpaste containing 500 ppm fluoride is swallowed this results in the same intake of fluoride as, for example, from fluoride salt. Based on the new recommendations, the amount of fluoride swallowed can be doubled. In the case of toothpastes with a higher fluoride level (as of 1000 ppm), the risk of fluorosis is even greater.
Kinder Karex Toothpaste uses the tooth-like active ingredient hydroxyapatite. When swallowed, it simply dissolves in the stomach.
Numerous studies have confirmed the efficacy of hydroxyapatite: This substance repairs enamel every time the teeth are brushed, minimises the build-up of bacteria and thus provides effective protection against caries.
