White Dark Stains is an easy-to-use teeth whitening product that is safe for your teeth and specifically formulated with Dark Pigment Adsorption Technology. This technology is based on the powerful and binding properties of encapsulated activated carbon micropearls. These micropearls will adsorb, neutralize and eliminate dark stains and bad breath due to smoking, drinking tea, coffee and/or red wine, upon activation. iWhite Dark Stains will also prevent deposit of dark stains.
