I White Dark Stains Toothpaste is using Dark Pigment Adsorption Technology. This technology is actively targeting dark stains by adsorbing and eliminating colored substances. The Dark Stains technology that has been developed to remove stains relies on 3 main actions: 1-Capturing dark stains and eliminating bad breath (thanks to the activated charcoal). 2- Loosening and splitting of dark stains (PAP will attack the stains and split them into smaller and less colored molecules). 3- Shielding the enamel: creating a protective layer on the enamel. Benefits: • I White Toothpaste helps remove coffee, tea, and tobacco stains. • Helps to get rid of bad breath. • I White toothpaste works great for teeth whitening.
