Activated Charcoal Teeth Whitening: Is It Safe and Does It Work?

If you’re on Instagram, there’s a 99% chance that at some stage, you will have seen photos of Insta influencers smiling, with their teeth covered in a black, grainy foam. It’s quite ironic that a toothpaste that looks like mud is turning people’s heads with the promise of a whiter, brighter set of teeth! 

Activated charcoal for teeth whitening is a growing trend for patients who are seeking a more natural teeth whitening alternative to in-chair teeth whitening and take-home teeth whitening kits. These traditional methods use bleaching agents to remove extrinsic teeth stains from smoking cigarettes or consuming foods and drinks like red wine or coffee, as well as intrinsic tooth discolouration from ageing, medication or trauma.

Activated charcoal toothpaste and activated charcoal teeth whitening powder are being promoted as being effective for creating a whiter and healthier smile, which unfortunately dental professionals are not sure about. 

What is activated charcoal?

Activated charcoal is a powder made from coconut shells, bone char, peat, petroleum coke, and coal. The ingredients are processed at a very high temperature, making it activated and more porous. 

Does activated charcoal whiten teeth?

When answering the question, “how does activated charcoal whiten teeth?”, many activated charcoal teeth whitening companies will state that the abrasion of the powder along with  the negatively charged, porous texture of activated charcoal helps to trap toxins from your teeth and mouth, removing the stains. 

The reality is, the discolouration in your teeth is not a toxin! Therefore, the theory that this charcoal can whiten your teeth is not yet proven. 

Is activated charcoal safe for your teeth?

Brushing your teeth with activated charcoal has been associated with several risks, which are important to keep in mind when researching at-home teeth whitening:

  • Enamel erosion: Activated charcoal is abrasive and can wear down tooth structure. Once this is deteriorated, it cannot be naturally repaired. The outer part of the tooth structure is enamel, the white and brighter part of the teeth. The inner part of the tooth structure is called dentine and this has a yellowish darker shade. When you brush with an abrasive paste daily, morning and night, eventually the enamel will wear down, which means your teeth will be less white. 
  • Tooth sensitivity: Not only the appearance of the teeth are affected by erosion, but you are also increasing the chances that you will experience tooth sensitivity. This means that you can feel pain or sensitivity when brushing your teeth or when you consume cold/hot foods or drinks. 
  • Lack of tooth decay prevention: Another risk when continually using activated charcoal toothpaste is that it does not help in preventing tooth decay due to the lack of fluoride in these products. You may have an increase in plaque build up  and possibly more chance of gum disease and dental decay occurring. We recommend using a non-abrasive toothpaste with fluoride to prevent tooth decay, and making sure you have a regular 6-monthly check-up and clean to keep your teeth in top shape.

These are just a few facts about teeth whitening you need to know!
