When I say “charcoal toothbrush” you probably think “CIA torture report.” You should actually be wondering “cutting edge dentistry or snake oil?” Yes, the charcoal toothbrush is an actual product that’s available here for about $10.
The important part is that this is activated charcoal, which is the kind that gets used in water filters and odor removers an the like. The manufacturer describes the bristles’ properties thusly: “Binchotan charcoal is blended into each bristle of this toothbrush which helps give off negative ions, helpful for deodorizing and removing plaque, preventing bad breath, and harmful bacteria from growing within the brush.”
The Amazon page is also full of BS reviews like this gem: “Just what my grandson ordered for Christmas, thanks!” Absolutely nobody’s grandson got excited about a toothbrush for Christmas. This kid probably also wanted Brussels sprouts, a copy of Quicken Rental Property Manager 2015, and some homework.
