The exclusive formula of Biorepair® Pro White toothpaste combines the properties of microRepair®, biomimetic particles that can repair enamel and dentine, with the innovative patented technology of the whitening PVP polymer. The micro-particles remineralize the enamel, repairing it and protecting it from the erosion it is exposed to every day, restoring your teeth’s natural whiteness and leaving the surface smoother. At the same time, the PVP technology creates a thin filter that captures substances that can stain before they are deposited on the teeth, making them brighter day after day.
