Black on White: Activated Charcoal and Your Teeth

Black on White: Activated Charcoal and Your Teeth

The teeth whitening trend has turned black, thanks to activated charcoal. From YouTubers to bloggers, the Internet is diehard for this dark paste.

Take a look at the science behind the trend:

What is it?
Activated charcoal is different from the kind that fills naughty children’s stockings or the stuff you throw on the grill. Charcoal becomes “activated” when high temperatures are mixed with gas. This combination causes it to expand and become porous, trapping the impurities around it.

The Claim
Manufacturers claim their charcoal-containing toothpaste and toothbrushes can “kill microbes and absorb gasses causing odor.” This claim has yet to be tested, as research is still ongoing.

We do know that charcoal is abrasive. If it’s too tough on teeth, the product can prompt pearly whites to look more yellow than before. Strong substances can wear away enamel and expose dentin—the softer, yellowish layer of a tooth. 

Better Safe than Sorry
Its effectiveness has failed to be proven, and the safety of charcoal whitening products is a big question mark.

Remember: The tooth-whitening market is a billion-dollar industry, so if charcoal were safe and effective, big brands would be selling it.
