What is the weirdest thing you've seen in toothpaste? For a couple of years now, charcoal seems to be popular in toothpastes. This particular toothpaste by Colgate claims to deep clean with the charcoal! The toothpaste is white in color with some black streaks. So it is not black toothpaste. I wonder how this works. Maybe it's from the prehistoric days when humans or animals used natural things or whatever was available to brush their teeth!
