You may be as stunned as I was when I first came across this product. Yes, you can use charcoal to whiten your teeth. Now you probably shouldn’t rum your gums with the coals left from your latest bbq but the hello charcoal toothpaste tablets are formulated with activated charcoal, coconut oil, and real mint. They also have a line of other dental health-related products that compliment their charcoal toothpaste tablets.
