Will Activated Charcoal Whiten My Teeth?

Answering Questions About the Popular Toothpaste Ingredient

Activated charcoal has been touted as a miracle tooth for whitening your teeth, but is it really something you should use on your smile?

There’s a new wellness ingredient that has been taking the world by storm: Activated Charcoal. Most commonly found in skincare products like face masks and other beauty products, charcoal has been toted as an all-natural way to achieve many things including a whiter smile.  

Does this wonder ingredient actually whiten teeth? We dive into the popular trend and dispel the rumors surrounding its miraculous smile benefits.  


What is ‘Activated Charcoal’ and How Does it Work?

Charcoal is a rough material that can damage the surface enamel of your teeth when used in place of toothpaste.

Seemingly new to today’s beauty market, activated charcoal has a long history of use dating back to the ancient Romans and English working class of the 1800s. Created by burning carbon-rich materials such as bamboo, wood, coconut shells, olive pits, or coal, activated charcoal is porous like a sponge and is typically used to soak up substances like medication or poisons before it can be absorbed in the body.

In the past, it has been used in place of toothpaste and scrubs, but is this ingredient an effective tool for whitening teeth?


The Dangers of Using Charcoal Toothpaste

The short answer to this question is no, activated charcoal is not a good way to whitening your teeth. In fact, according to the Pharmaceutical Journal, there have been no scientific studies that have proven the advertised benefits of charcoal for teeth whitening.

What may first appear as whiter teeth can really be the first signs of enamel erosion. Charcoal is an incredibly abrasive material and its grittiness, though heralded as a surface stain remover, actually wears down the surface enamel of your teeth.

Signs of Enamel Erosion

Translucency • Rounded Edges • White Spots • Yellowing • Tooth Sensitivity


When continuously used, enamel (which acts as insulation against sensitivity brought on by hot and cold substances) is scrubbed away to reveal the soft layer of our teeth called ‘dentin.’ Yellow in color, dentin contains the nerves and blood vessels which, when exposed, lead to severe pain and discomfort. As our surface enamel is not a material that can grow back, the longer dentin is exposed, the more likely we are to developing cavities, tooth decay, and eventual tooth loss.

Best Way to Whiten Teeth

In-Office Whitening is a safe and painless way to improve the appearance of your smile!

If you’re concerned about the color of your smile, one of the best proven methods of brightening teeth is with in-office dental whitening – one of the many cosmetic procedures we offer at Alexandria Smiles. Not only is this proven to be safe when performed by trained and qualified medical professionals, the procedure is quick and painless with impressive results.

Another safe (and natural) way to maintain a white smile is by avoiding foods and drinks that stain your teeth. Examples include coffee, cola, tea, red wines, and other dark-colored foods. Be sure not to smoke or use tobacco either, as these are also common causes for yellowing teeth.

The most important tip we have for a white smile is to maintain a regular dental hygiene routine. By brushing twice daily and flossing once a day, your teeth will stay healthy and your mouth will benefit greatly. Are you interested in brightening your teeth?
