Activated charcoal is tasteless and also odorless and works by the process of absorption. This activated charcoal use is cost-effective and an all-natural solution for a bright smile. GENTLE, EFFECTIVE & OPTIMAL ORAL HYGIENE: Activated charcoal is very porous and the substance will bind toxins and absorb tannin which are pigments found in some drinks and foods.
