The outstanding results on the mode of action of hydroxyapatite have already been demonstrated in more than 200 international studies including clinical trials. During brushing, the microcrystalline structure of hydroxyapatite is proven to adhere to the enamel surface. It remineralises microscopic defects whereby it form a protective layer that prevents the natural enamel from daily wear and tear.
With the daily use of Bioniq® or KinderKarex Toothpastes, teeth not only feel smoother, but also stay cleaner for longer, as the bacteria find it harder to build up on the surface of the teeth. The formation of dental plague is reduced preventing cavities and protecting healthy gums. Sensitivity to pain is also reduced. At the same time hydroxyapatite also has a visual effect, due to the white nature of the biomimetic crystallites tooth-discoloration caused by so-called extrinsic stain, for example from nicotine, tea or red wine can be reduced.
