Beware of Charcoal Toothpaste

We have had many questions recently about using charcoal toothpaste to achieve whitening.

Charcoal was used in the 1900’s to treat poisoning and overdoses. It was thought to absorb the toxins. However, using it to clean or whiten teeth can have poor oral effects.


Although you may not notice it immediately, activated charcoal can wear away your tooth enamel. It is too abrasive to safely use on your teeth. Once the enamel layer is worn away, the layer beneath (called dentin), becomes more visible. This layer is naturally yellow which means your teeth could actually become more yellow than they were before you used charcoal toothpaste.
Therefore, we are not recommending charcoal toothpaste. The best way to whiten your teeth is with professional whitening under the care of your dentist.
