Charcoal toothpaste has exploded on social media with promises of whiter teeth and natural detox benefits. Charcoal is now a common ingredient in face masks, exfoliators, and pore strips - so much so that it barely surprises consumers anymore. But when charcoal toothpaste hit the market around 2019, it certainly caught people’s attention.
So, what do dental professionals think of this new trend? Unfortunately, not much - and for good reason.
Dentists say: “Charcoal toothpaste can be harmful”
Researchers have analysed more than 50 different charcoal-based toothpastes, and the results have raised serious concerns within the dental community. Here's what they found:
- Lacks fluoride: Over 90% of charcoal toothpastes tested did not contain enough fluoride - an essential mineral that protects teeth from decay.
- No protection against cavities: These toothpastes were ineffective against 95% of the bacteria that cause tooth decay and gum disease.
- Minimal whitening effect: Despite the marketing claims, charcoal toothpastes had too few whitening agents to make a noticeable difference.
- Damaging to enamel: Charcoal particles are highly abrasive. Rather than polishing the teeth, they can strip away enamel, which doesn't regenerate once it's gone.
In fact, countries like the United States, Japan, Australia, China, and South Korea have discussed restrictions or bans on oral care products containing charcoal micro-particles due to these risks.
In Australia, charcoal toothpaste only entered the market recently, promoted as a “safe and effective” whitening option. However, according to experts from the Australian Dental Association, the American Dental Association and the British Dental Association, that claim doesn’t hold up.
These reputable organisations caution against the use of charcoal-based dental products due to the potential for enamel erosion and the lack of fluoride - both of which are critical factors in maintaining oral health.
Professor Damien Walmsley from the BDA stated, “Charcoal-based toothpastes offer no silver bullets for anyone seeking a perfect smile and come with real risks attached. So don’t believe the hype.”
