Activated charcoal isn't anything new, but the substance has been popping up lately in all kinds of wellness and beauty products ranging from supplements to shampoo to toothpaste. We're here to talk about the latter. Some people swear the pitch-black paste whitens their teeth, while others simply prefer plant-based formulas.
According to Sanda Moldovan, DDS, one of the main draws of charcoal is that it's detoxifying. "It attracts plaque due to its negative charge," she tells Byrdie. "Plaque is 99 percent bacteria, which has a positive charge, so the interaction is just what is needed for maintaining a healthy oral cavity." Bear in mind the American Dental Association (ADA) only gives its stamp of approval for fluoride toothpaste, but lots of options contain both fluoride and charcoal.

Dental hygienist Shannon Nanne says charcoal formulas might be a solid alternative for those sensitive to hydrogen peroxide bleaching products, but so far, research on charcoal's teeth-whitening effects hasn't been conclusive. "Patients need to be careful when choosing a toothpaste with charcoal," she adds, explaining that some powders can be abrasive against the teeth.

Our first choice is Hello, a pitch-black toothpaste that promises noticeably whiter teeth with regular use. Unlike some others in its category, it's formulated to be safe for your enamel.
"Many patients with sensitive teeth and gums cannot tolerate the bleaches in whitening toothpaste. Others with dry mouth cannot use products with bleach," says Nanne.
In addition to activated charcoal powder, it contains hydrated silica to boost the brightening effects, coconut to soothe and protect the gums, and fluoride to fend off cavities. (There's also a fluoride-free version.) We're big fans of the slightly sweet, minty flavor too.

Best Charcoal Toothbrush: Orasana Bamboo Toothbrush with Charcoal Bristles
Minimizes mouth bacteria
"I prefer charcoal in the toothbrush bristles because charcoal toothpaste can be quite messy and stain the sink," says Dr. Moldovan, explaining how charcoal-infused bristles have shown to do a better job of eliminating bacteria than regular bristles. "I love the Orasana Bamboo Toothbrush."
Active Ingredients: Bamboo charcoal
Our top choice is hello Oral Care Activated Charcoal Fluoride Whitening Toothpaste, a pitch-black toothpaste that flaunts natural brightening power without damaging your enamel. But if you're open to spending a little more, Curaprox Black Is White Charcoal Toothpaste and Toothbrush Set is an excellent non-abrasive formula that makes your teeth look instantly whiter.
What to Look For in a Charcoal Toothpaste
If your teeth are sensitive or have enamel damage, you should speak to your doctor before using charcoal toothpaste. The abrasive nature of some charcoal toothpaste could potentially wear down the enamel, leading to increased sensitivity and enamel damage that is irreparable.
Fluoride vs. Fluoride-Free
The concept of charcoal toothpaste is often synonymous with fluoride-free products. This is not necessarily a negative thing, but we recommend chatting to your dentist to decide if fluoride is an important ingredient for you.
Charcoal toothpaste often uses essential oils for flavor, while others rely on artificial flavors. Check the flavor and ingredients list to see if it is compatible with your preferred tastes. Essential oils can be strong and some might find them too intense.
What is charcoal?
According to oral care expert Dr. Brigitte White, activated charcoal is a fine black powder derived from certain natural resources (like wood or coconut) and heated to an extremely high temperature. This process makes the powder porous, enabling it to absorb certain toxins and contaminants from the body, like mouth odor and surface stains (think coffee, berries, and red wine).
Does charcoal toothpaste work?
Dr. White explains that there are no long-term studies to determine whether activated charcoal products are safe or effective regarding dental hygiene. Her advice is to be cautious when using them for a prolonged period and seek the advice of a dentist if you’re unsure.
Is charcoal toothpaste safe?
Overall, yes, charcoal toothpaste is safe, but speak to your dentist about specific products if you’re confused or concerned. Some research suggests the claims made by charcoal toothpaste brands can be misleading and the products ineffective.
Does charcoal toothpaste whiten teeth?
There's no concrete scientific evidence to prove that charcoal toothpaste will whiten teeth, but there are a lot of positive testimonials from users. Charcoal is often combined with other whitening ingredients as well for added benefit.
