Although there are toothpastes that are specifically made to be infused with activated charcoal, I decided to try a cheaper but more labor-intensive option: DIY charcoal toothpaste.
All you need is a bottle of charcoal capsules, a toothbrush, and a sink. I would recommend splurging on a new toothbrush instead of dirtying your regular one.
Simply wet your toothbrush and carefully pull the capsule apart in your sink. Then sprinkle its black contents onto the bristles. Pop the brush into your mouth and brush normally for the dentist-recommended two minutes.
Not surprisingly, you’re going to have to rinse more than usual to wash the black residue out of your mouth completely
