You can use activated charcoal or common ground charcoal from your kitchen to remove discoloration from your teeth.
It’s believed that charcoal can remove pigments and stains from your teeth because it’s highly absorbent.
It’s said to also get rid of bacteria and toxins in the mouth. There is a toothpaste that contains activated charcoal and claims to whiten teeth.
This is how to use activated charcoal or raw charcoal to brush off stains on your teeth. Open a capsule of activated charcoal and put the contents on your toothbrush.
Gently brush your teeth using small circles for 2 minutes. Be especially careful in the area around your gums as it can be abrasive. Then, spit it out. Don’t brush too aggressively.
If your teeth are sensitive or you want to limit the abrasiveness of the charcoal, you can dab it on your teeth. Leave it on for 2 minutes.
You can also mix activated charcoal with a small amount of water to make a mouthwash. Swish this solution for 2 minutes and then spit it out. Rinse your mouth thoroughly with water after using activated charcoal.
However, research has found that activated charcoal can be abrasive if left in the mouth for too long and, may alter tooth-colour restorations, leading to loss of tooth structure.
