Activated coconut charcoal has an amazing ability to attract substances and bind them. When added to our Charcoal Whitening Toothpaste, it works to extract toxins and stains from your mouth. It kills tooth decaying bacteria that may lead to gingivitis while leaving your teeth whiter and your mouth cleaner.
