Korean Charcoal Toothpaste

Korean Charcoal Toothpaste
If charcoal is good enough for my Britta water filter, it should be good enough for my teeth. Such is the logic of Charcle, a Korean toothpaste, which uses the cleaning properties of charcoal as an active ingredient in their toothpaste. The black color is rather unfortunate for something you have to put into your mouth.
