Our teeth are exposed to constant mechanical and chemical attacks. Chewing, brushing when we clean our teeth, and acidic food and drink all attack the teeth. Once it has been worn down, enamel cannot be reproduced by the body. The artificial enamel in Bioniq Duo repairs microscopically small defects and forms a protective layer against wear when used regularly. In this way, Bioniq Duo fights the cause of pain-sensitive teeth in a natural way. Hydroxyapatite crystallites (artificial enamel) occlude exposed dentinal tubules and adhere to the surface of the teeth. This repairs the surface of the enamel and dentin and effectively reduces sensitivity to pain.
