All Bioniq® Repair-Toothpastes have an extremely gentle formulation. This means they can also be used if a patient has implants and in the case of fixed or removable dentures. As well as hydroxyapatite (BioHAP), the main active ingredient, Bioniq® Repair-Toothpastes also contain cleansing substances and mild surfactants. Gentle abrasive particles are also used to avoid damaging implants, crowns or fillings.
