Choose one of our Binchotan charcoal infused Adult Soft Dupont nylon bristle toothbrushes to get a brilliant smile. Charcoal bristles are known to absorb chemicals such as chlorine from tap water. The charcoal works by acting like a magnet for plaque and tannins that may stain teeth. This effect is enhanced by combining our charcoal bristle toothbrush with activated charcoal toothpaste!
