Does Charcoal Whiten Teeth

Activated charcoal has emerged as a popular natural teeth whitening remedy. It is believed that charcoal can reduce the appearance of surface stains and grant a brighter smile. Everybody desires pearly whites and a radiant-looking smile. But the big question is, ‘Does charcoal whiten teeth?’ In this post, we’re going to explore the benefits of charcoal for whitening teeth and the potential risks of excessive use.

What is Activated Charcoal?

Activated charcoal is a fine-grain powder acquired from materials such as wood, coconut shells, and various other natural substances. This powder is produced through an oxidation process achieved by exposing the material to high heat. Nowadays, activated charcoal is found as a common ingredient in face scrubs, masks, and toothpaste formulations, as it is believed to remove toxins and bacteria.

How To Whiten Teeth With Charcoal?

Charcoal toothpaste has gained popularity as many people believe in its teeth whitening effects. Unlike ingredients such as hydrogen peroxide or carbamide peroxide, which bleaches teeth, charcoal works differently. It sticks to the tooth surface due to its absorbent properties and helps remove bacteria and plaque, major causes of yellowing teeth.

To use activated charcoal powder:

  • Dip a wet toothbrush into the powder.
  • Gently brush your teeth for a minute.
  • Thoroughly rinse your mouth with water to remove any residue.
  • Limit usage to thrice a week to avoid potential dental issues due to overuse.

However, because there’s a lack of scientific evidence supporting the effectiveness of charcoal for teeth whitening, dentists and professionals advise caution when using this product. There are some concerns:

  • The black colour of charcoal may potentially further stain teeth and get trapped in the crevices or lines of aged teeth.
  • Its abrasive texture could wear down the tooth enamel, exposing the dentin, the yellow tissue beneath the enamel, leading to increased yellowing and tooth sensitivity.
  • It’s not recommended to use on dental restorations such as crowns, dentures, and veneers, as the dark colour might accumulate in the lines or cause tooth discoloration.

Benefits Of Brushing Teeth With Charcoal

  • It may help combat bad breath.
  • It’s mildly abrasive which may reduce bacteria and plaque buildup.
  • Activated charcoal toothpaste may be effective in whitening lighter stains.
  • It could help in maintaining whiter teeth after a professional cleaning session.


Activated charcoal has become a trendy DIY teeth whitening solution, but its effectiveness lacks scientific evidence. It should be used with caution, especially if you have existing dental issues. It’s always a good idea to share your concerns with a Turramurra dental professional before using natural remedies. They can provide better alternatives and personalised advice for you.
