Hydrogen-peroxide is the only substance clinically proven to whiten teeth. This is why all "whitening" dental products list hydrogen peroxide as the active ingredient.
However, all dental products also have synthetic flouride in them, which is toxic to human health, specifically, synthetic flouride can be classified as a neurotoxin.
THIS PRODUCT HOWEVER, does NOT contain flouride. Most importantly, the ingredients are based on traditional and effective dental cleaning and whitening techniques.
