How does activated charcoal whiten teeth?
During the process of heating, the charcoal will have a lot of internal spaces and pores. The porous texture of activated charcoal helps to trap toxins from your teeth and mouth, dissolves tea, coffee, and wine stains, removes the plaque, and makes your teeth look brighter. The stains have a positive charge, while the activated charcoal has a negative one. The two will attract each other when meeting. So the stains can be adsorbed by the charcoal.
