Children's Toothpaste with BioHAP Instead of Fluoride

The use of fluoride in toothpaste is particularly controversial for children under 6 years of age. Children in particular swallow a large portion of the toothpaste.

Due to the intake of additional sources of fluoride (vitamin D supplements with fluoride, fluoridated salt, etc.), the risk of developing fluorosis (white spots on the teeth caused by increased fluoride intake) increases significantly. For example, the German Federal Institute for Risk Assessment points out that if a children’s toothpaste with 500 ppm fluoride is swallowed, just as much fluoride is ingested as, for instance, through fluoridated salt.

According to the new recommendations, the amount of swallowed fluoride can therefore double. The risk of fluorosis is significantly higher with toothpastes that have a higher fluoride content (from 1000 ppm).

KAREX relies on the tooth-related active ingredient Hydroxyapatite (BioHAP) in all products. When swallowed, it is simply dissolved in the stomach. Numerous studies confirm its effectiveness: Hydroxyapatite repairs enamel with every brushing, reduces bacterial adhesion, and thus provides effective protection against cavities.

Our tooth enamel consists almost entirely of Hydroxyapatite. That is why BioHAP (biomimetic Hydroxyapatite) is used as an active ingredient in oral care. The highly concentrated active ingredient also serves as a source of calcium and protects our teeth against bacterial acids. Numerous studies confirm the benefits of Hydroxyapatite in the field of oral care and prevention.

Yes, BioHAP protects just as effectively as fluoride against cavities. BioHAP forms a protective layer on the tooth surface that prevents bacteria from adhering to the tooth and thus helps prevent cavities and gum inflammation. In addition, BioHAP releases calcium during acid attacks, which protects the teeth.

In contrast to many other fluoride-free toothpastes, KAREX uses Hydroxyapatite (BioHAP) as its active ingredient. This is the substance our teeth are made of. BioHAP protects at least as effectively against cavities as fluoride – without the risks of overdosing.

KAREX is “Made in Germany” and is developed and distributed by the Dr. Wolff Group, a fourth-generation family-owned company based in Bielefeld.

Numerous publications confirm the effectiveness of BioHAP in dental care. These include not only laboratory studies (in vitro) but also studies with test specimens under oral cavity conditions (in situ), as well as, in particular, clinical studies on patients (in vivo).
