All Bioniq 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 the main active ingredient, hydroxyapatite, Bioniq Toothpastes also contain cleansing substances and mild surfactants. Gentle abrasive particles are also used to avoid damaging implants, crowns or fillings.
