Does charcoal toothpaste work?

It has been claimed to whiten teeth, but is it worth the hype?

The teeth whitening business is estimated to be worth $11 billion with everyone and their mother trying to achieve their biggest, brightest, whitest smile.

Nowadays sparkling pearly whites are achievable — not to mention affordable — thanks to ever-evolving tech and treatments with charcoal toothpaste being one of the trendiest on the market.

What is charcoal toothpaste?

Charcoal toothpaste is a natural product made by slow-burning natural materials, such as coconut shells or bamboo, that are oxidised under extreme heat. This causes it to become more porous, so it can basically act like a magnet and pull out toxins and chemicals.

It is used in beauty products, supplements and even in hospitals where it treats patients that have been poisoned or have had a drug overdose.

It acts in the same way on teeth with tiny pores binding to surface stains and removing them. 

While it is said to remove stains – such as coffee, tea, red wine, tobacco etc. – charcoal toothpaste doesn’t actually “whiten” teeth.

Due to its absorbent properties, activated charcoal is also said to alleviate intestinal gas, lower cholesterol levels, prevent hangovers (although it doesn’t absorb alcohol) and help regulate bile flow problems during pregnancy.

Does charcoal toothpaste actually work?

The dental industry has been known to pour cold water over many whitening treatments, in particular DIY whitening kits, that can damage enamel, but many dentists believe that activated charcoal is totally worth the hype … but it comes with a warning.

It is said to remove stains (but does not whiten), balances oral pH and improves halitosis (bad breath) and helps our overall dental health.

However, according to the Independent, a study earlier this year in the British Dental Journal found that the abrasive property of charcoal can cause erosion of enamel much more quickly than using regular toothpaste.

Dr Linda Greenwall, lead author of the study and member of the British Dental Bleaching Society, who conducted the research, urged consumers to check the ingredients of charcoal-based toothpastes before use to ensure they contain fluoride. 

Calcium and phosphate are also needed in order to strengthen enamel, she added.

“When used too often in people with fillings, it can get into them and become difficult to get out,” Dr. Joseph Greenwall-Cohen, co-author of the study from the University of Manchester Dental School, told the BBC. “Charcoal particles can also get caught up in the gums and irritate them.”

As its long-term effects and safety are still not known, some dentists have advised to err on the side of caution if you’re using a charcoal-infused paste and to brush very gently to avoid wearing down the surface enamel.

Other dentists suggest not to brush with the charcoal at all, but to slather it on teeth and leave it for up to five minutes.

Can you make it yourself?

As well as there being dozens of charcoal toothpaste-type products on the market, there are numerous instructions online for DIY charcoal toothpaste.

Dr. Burhenne on AskTheDentist.com has created a popular recipe that should take around 20 minutes and includes the ingredients: 2 teaspoons activated charcoal; 3 teaspoons calcium carbonate; 1 teaspoon food grade bentonite clay; 2 1/2 teaspoons xylitol; 4 teaspoons distilled water; and 2 teaspoons cold-pressed organic coconut oil.

But if you are not up for trying that, here are five popular activated charcoal toothpastes in Australia:
