BlanX Advanced Whitening is the first whitening toothpaste that derives from natural Arctic Lichens which help to restore teeth to their natural whiteness. The Arctic Lichens offer a deep cleaning action whilst killing bacteria and removing plaque. A non-abrasive and peroxide free toothpaste that is suitable for daily use to whiten teeth without harming tooth enamel. During an expedition to the North Pole, scientists noticed that the local population had extraordinarily white and healthy teeth. Their only oral hygiene consisted of rubbing their teeth with a lichen that grew abundantly at those latitudes. Lichens produce natural antibacterial substances which can control the amount of bacteria present on your teeth helping to prevent plaque that leads to tooth discoloration. From this observation, the researchers were able to isolate the active ingredient present in the lichen and create the unique formulation.
