Many toothpastes are coming out on the market containing activated charcoal. The idea behind using activated charcoal comes from its ability to absorb and bind to drugs and toxins, thus ridding the body of unwanted substances. Activated charcoal is often used by hospitals and poison control to manage a poisoning of certain substances. This is currently the only medically approved use of activated charcoal. However, there are studies indicating its use in treatment for other medical conditions.
Many products claim to have various benefits for your oral health, including being antimicrobial, antifungal, antiviral, and detoxifying. Scientific studies have demonstrated none of these abilities. A 2017 issue of the Journal of the American Dental Association found no evidence that dental products with charcoal are safe or effective for your teeth.
Additionally, using products containing charcoal are actually very abrasive on your teeth. Abrasive products like charcoal toothpaste remove enamel and make the teeth look more yellow, instead of whitening as many products claim. When you wear away the enamel, the next layer of tooth, dentin, may be exposed, which has a yellow appearance.
Make sure to consult with Drs. Katie and Stephanie before using any whitening products with your children, as many whitening products are not safe for kids.
