The Truth About Charcoal Toothpaste: Benefits and Risks

In recent years, charcoal toothpaste has become a trendy product in the oral care world, boasting claims of natural teeth whitening and detoxifying benefits. But what does science say about it?

The Rise of Charcoal Toothpaste

Activated charcoal is not the same as the charcoal you use to grill. It’s made by heating carbon-rich materials to high temperatures, increasing its absorptive properties. In skincare and healthcare, activated charcoal is lauded for its detoxifying effects. When it comes to oral care, charcoal toothpaste claims to absorb toxins and stains, leading to a brighter smile.

The Benefits

Natural Whitening: Charcoal toothpaste can provide some whitening effects by removing surface stains on the teeth.

Toxin Removal: Activated charcoal can absorb and bind with toxins, potentially improving oral health by reducing bacterial load.

The Risks

However, the American Dental Association (ADA) has expressed concerns about the use of charcoal toothpastes:

Abrasive Nature: Some charcoal toothpastes can be too abrasive, potentially leading to enamel erosion and dentin exposure. This can make teeth more susceptible to cavities.

Lack of Fluoride: Many charcoal toothpastes don’t contain fluoride, a mineral crucial for preventing tooth decay and strengthening enamel.

Insufficient Evidence: The ADA mentions that there’s not enough evidence to verify the safety and efficacy claims of charcoal toothpastes.


While the idea of naturally whitening teeth is appealing, it’s essential to be informed. Before making a switch, it’s a good idea to consult with your dentist to ensure the toothpaste you choose is both effective and safe for your oral health.
