The Bioniq ® Repair-Toothpaste contains biomimetic hydroxyapatite, better known as artificial enamel. It accumulates on the surface of the teeth and protects them. But even more, it is not just a matter of accumulation and the development of a protective layer. The (demineralised) acid-weakened teeth are provided with minerals by daily brushing with the Bioniq ® Repair-Toothpaste. That means, in daily use, the Bioniq ® Repair-Toothpaste with artificial enamel repairs microscopically small defects in the enamel surface. Accordingly, the teeth feel smoother and it is more difficult for bacteria to adhere to the teeth. The active principle has been proven by scientific studies.
