So the other day my wife ended up picking me up charcoal toothpaste along with a charcoal infused toothbrush. Apparently it's becoming a thing now in toothpastes. Has anyone else used it? It is strange, I mean it comes out black and when you spit it's a dark grey. Surprisingly it's suppose to be good for you teeth, along with removing stains. Picture is for reference, I don't know what brand she got me.
