Sugar-free chewing gum with sweeteners and citrus and menthol flavor. Good for the teeth. You do not want to miss out on the pleasure of coffee, tea or red wine, but still do something to discolour your teeth? Then Extra Professional White Citrus is just right for you. Because the chewing of these chewing gum dragees reduces tooth discoloration: It contains specially developed microgranules, which spread through the chewing in the mouth, slowly dissolve and replace the toothbrush on the way. And with the sparkling citrus-menthol flavor, the benefit of whiter teeth is not difficult at all.
