Always Convinced — With BioHAP Instead of Fluoride

Clinically confirmed: KINDER KAREX Toothpaste is the first and only fluoride-free toothpaste with Hydroxyapatite to be approved in Canada by the health authorities (Health Canada) as an anti-cavity toothpaste. It is therefore a so-called "Natural Health Product." This product status can only be achieved when scientifically sound clinical data on efficacy and safety are available. In addition, the efficacy of the toothpaste with Hydroxyapatite has been confirmed by the Canadian Dental Association (CDA).

Fluoride has long been used in cavity prevention, but it can carry risks — especially for children. KAREX is therefore taking a new approach: We rely on BioHAP, the scientifically proven active ingredient that prevents cavities just as effectively as fluoride — but without the risks. This makes KAREX the modern, safe choice for tooth protection for everyone — from the very first tooth.

BioHAP stands for biomimetic Hydroxyapatite — the main component of our natural tooth enamel.

BioHAP helps protect against cavities and remineralize damaged tooth enamel.

Numerous scientific publications confirm the effect of Hydroxyapatite in oral care. BioHAP is at least as effective as fluoride in cavity prevention.

Small children usually cannot spit out toothpaste properly yet and swallow a large portion of it – with BioHAP this is harmless. No strict dosage requirements as with fluoride-containing toothpastes.

The permanent damage to tooth enamel (fluorosis) is caused by an overdose of fluoride. KAREX is effective without fluoride. Toothpaste with BioHAP can be swallowed without hesitation.
