To whiten your teeth naturally, wet a toothbrush and dip into powdered activated charcoal. Brush teeth as normal, paying special attention to areas showing the most staining. Sip a bit of water, swish through mouth thoroughly and spit. Rinse well, until spit is clear. Put some toothpaste onto your toothbrush as you would normally do. Dip your toothbrush into the activated charcoal, completely covering the toothpaste with the black powder. Then brush your teeth as usual! While you brush your teeth, your mouth will turn completely black Once you rinse, the color should disappear. If it doesn’t, rinse off your toothbrush and brush your teeth with water only. Follow these steps and you’ll have a bright white smile in no time!
