Charcoal toothpaste may scrub away some surface stains, but strong evidence that it whitens teeth is lacking, and it may wear down your enamel over time. If you’re tempted to try it, here’s what you should know first.

Plenty of teeth-whitening myths circulate about brightening your smile at home instead of using a whitening kit or professional whitening. Some can damage your teeth, while others may help a little. One of the most popular is charcoal toothpaste. Beavers & Broomfield Family Dentistry can clear up the myths: Does charcoal toothpaste work? Is it safe? And how does it compare to other options?

What Is Charcoal Toothpaste?

Charcoal toothpaste is regular toothpaste with activated charcoal added. Activated charcoal is made by heating materials like wood or coconut shells to very high temperatures, then treating the result to make it highly porous. People have used it for medical and filtering purposes for years. It is not the same as the charcoal you grill with, so please don’t brush with a briquette.

Does Charcoal Toothpaste Whiten Teeth?

Does charcoal whiten teeth? It can make them look slightly brighter, but mostly by scrubbing. Charcoal is a mild abrasive, so it can buff away surface stains from coffee, tea, and red wine, much like exfoliating the outside of your enamel. That’s different from true whitening, which changes the shade of the tooth itself.

A 2017 review in the Journal of the American Dental Association found insufficient scientific evidence that charcoal toothpastes safely or effectively whiten teeth. The authors also noted that none of the 50 charcoal products they reviewed carried the ADA Seal of Acceptance, which shows a product has been evaluated for safety and effectiveness.

Is Charcoal Toothpaste Safe for Your Teeth?

The safety of charcoal toothpaste hasn’t been proven, and the biggest concern is its abrasiveness. Using it often can wear down your enamel, the hard outer layer that protects your teeth. Enamel doesn’t grow back once it’s gone.

Thinner enamel can lead to tooth sensitivity and a higher risk of cavities. It can also make your teeth look yellower. The layer underneath the enamel, called dentin, is naturally yellow, and it shows through as enamel wears thin. So overusing charcoal toothpaste can leave your teeth looking darker instead of whiter.

Fluoride matters here too. It helps strengthen enamel, which is why most toothpastes contain it. Many charcoal toothpastes don’t, and the 2017 review found that very few of the products it examined listed fluoride. If you use one, check the label.

For daily brushing, stick with a fluoride toothpaste, ideally one with the ADA Seal. If you’re curious about charcoal, talk with your dentist first. We can check your enamel and tell you whether it makes sense for you.

Other Teeth Whitening Myths

Social media is full of home whitening hacks, and many can do more harm than good.

  • Lemon juice or apple cider vinegar: The acid can soften and wear away enamel.
  • Baking soda paste: It’s a mild abrasive, so frequent use can wear enamel the same way charcoal can.
  • Oil pulling: Swishing coconut or other oils in your mouth hasn’t been shown to whiten teeth.

Safer Ways to Whiten Your Teeth

The good news is that safer, better-studied options exist.

Whitening Toothpaste

Whitening toothpastes can help remove surface stains and keep new ones from building up. The results are subtle, and they won’t change your tooth color dramatically. Look for the ADA Seal on the box.

Home Whitening Kits

Whitening strips and trays use a peroxide-based gel to lighten stains. Results vary, but they may lighten teeth by a few shades after a couple of weeks. Home kits usually don’t whiten as much as professional treatment, and the results may not last as long. They can also cause temporary tooth sensitivity or gum irritation, so follow the directions carefully.

Professional Teeth Whitening

Professional teeth whitening is the fastest and most effective option. At Beavers & Broomfield Family Dentistry, treatment takes about an hour. We protect your gums, apply a peroxide-based whitening gel, and may use a curing light or laser to activate it. Many patients see a difference in a single visit, and additional visits can brighten your smile further.

Whitening can make your teeth more sensitive for a few days afterward. We may apply a fluoride rinse to help ease it, and if your teeth are sensitive, we can spread treatment over several visits with less whitener. Read more about preventing tooth sensitivity or choosing the right sensitive toothpaste.

Whitening doesn’t change the color of fillings, crowns, or veneers, so we’ll examine your teeth first and recommend what works best for you.

FAQs About Charcoal Toothpaste and Teeth Whitening

Does charcoal toothpaste really whiten teeth? 

It may remove some surface stains, but strong evidence that it whitens teeth is limited. It doesn’t change the natural shade of the tooth the way professional whitening can.

Can charcoal toothpaste damage your teeth? 

It can. Charcoal is abrasive, and frequent use may wear down enamel, which can cause sensitivity, make teeth look more yellow, and raise your risk of cavities.

How often can I use charcoal toothpaste? 

There’s no established safe frequency. Because of the enamel and fluoride concerns, we recommend a fluoride toothpaste for everyday brushing and checking with your dentist before trying charcoal.

What is the safest way to whiten my teeth? 

Professional whitening supervised by a dentist is the safest and most effective option. ADA-accepted whitening toothpastes and home kits can also help when used as directed.
