Key takeaways:
- Activated charcoal is believed to absorb stains off the teeth since it has been used in emergency rooms to absorb toxins in cases of poisoning/overdosing.
- There are no long-term studies that provide proof for the benefits of activated charcoal in whitening the teeth and removing bad breath.
- Dentists recommend that people who want to try activated charcoal toothpaste start sparingly and with lots of caution.
If you do decide to use activated charcoal toothpaste, dentists agree that you should do so cautiously and sparingly. Brush with it no more than once every other week, and not for an extended period of time, even if your teeth feel normal.
