Chogan Black Toothpaste contains activated charcoal to help eliminate bacteria and stains and whiten teeth. This toothpaste remineralizes the teeth and restores the physiological pH in the oral cavity. The sodium phosphate contained in the formula is able to remove magnesium and calcium from the saliva, preventing their deposition on the teeth and the formation of tartar; in addition, food particles and surface discolouration are removed. The formulation of the black toothpaste is natural and vegetable: it contains no animal fats, no alcohol and no ingredients harmful to the body and is non-abrasive. It is effective without being harsh on teeth and gums.
