The Bioniq Repair-Toothpaste contains biomimetic hydroxyapatite (BioHAP), better known as biomimetic 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 remineralised by daily brushing with the Bioniq Repair-Toothpaste. That means, in daily use, the Bioniq Repair-Toothpaste with biomimetic enamel repairs microscopically small defects in the enamel surface. Accordingly, teeth will feel more smoothly and for bacteria, it is more difficult to adhere to the teeth. The active principle has been proven by scientific studies.
