The innovative formula of the new toothbrush, mainly recommended for smokers, features bristles infused with calcium carbonate (CaCO3) for effective removal of dental stains caused by smoking. Teeth become whiter and more beautiful thanks to this natural whitening method, which is recognized as the most recommended natural whitening method. The firm bristles allow for optimal removal of bacterial plaque and stains, with Tynex fibers (the tips of the fibers are laser-cut to be gentle on enamel and to better clean interdental spaces) – the latest and most advanced material used for oral hygiene. The ergonomic yet linear handle ensures the correct and easy use of the toothbrush.
