    KINDER KAREX is suitable for babies from the first tooth. Thanks to the tooth-related active ingredient Hydroxyapatite (BioHAP), the toothpaste is suitable for all young children from 0 years of age who are not yet able to spit properly. Babies and young children can effectively protect their teeth against cavities with KINDER KAREX. The flavor has been chosen by children for children.

    About 97% of our tooth enamel and around 70% of our dentin consist of Hydroxyapatite. Tooth enamel forms the outer protective layer of the teeth. Bacteria attach to the enamel and, with the help of sugar from food, produce harmful acids. These acids dissolve the enamel, and cavities develop.

    KINDER KAREX Toothpaste contains the tooth-related active ingredient Hydroxyapatite, which adheres to the tooth while brushing. With daily brushing, even small defects in the enamel can be repaired by the active ingredient Hydroxyapatite, and a protective layer can form on the tooth. This protective layer makes it more difficult for bacteria to adhere to the tooth. KINDER KAREX with Hydroxyapatite thus provides effective protection against cavities.

    KINDER KAREX Toothpaste is also suitable for electric toothbrushes. KINDER KAREX Toothpaste is easy to dose and can be applied well even on smaller brush heads.
