How to Whiten Teeth With Charcoal

How to Whiten Teeth With Activated Charcoal

Years ago, a reader from India told me about a natural way to whiten teeth and it is the only method I’ve used since that time. Her suggestion? Whiten teeth with charcoal!

Whiten Teeth With Charcoal?

I was very skeptical that charcoal could actually help whiten teeth. I already kept activated charcoal around the house since we have kids and this highly absorbent substance is often used in hospitals for food poisoning. Because I kept it around the house, I’d also seen first hand what happens when it spills on a kitchen floor (grout = permanently ruined) so I was afraid it would stain my teeth and not whiten them.

How Charcoal Works

Activated charcoal is a highly absorbent substance. It removes toxins when they adhere to the surface of the charcoal. It is not absorbed by the body, but passes through the GI system, so chemicals and toxins adhere to it, which then pass through the body and are expelled by the digestive system.

In the 1800s, two men took lethal doses of poisons (including arsenic) and survived without harm… their secret: they mixed the poisons with activated charcoal powder. (Stating the obvious: do not try to repeat these experiments!)

Activated charcoal is extremely effective at binding to toxins from household chemicals, ingested medicines, and other chemicals from the body, especially when taken within 30 minutes of ingestion. For this reason, it is a great first treatment for any kind of poisoning, but should not be taken within several hours of medications (or even vitamins) that DO need to be absorbed.

I had used Activated Charcoal when I had an awful bout of food poisoning, and it worked wonders! I mixed about a tablespoon of activated charcoal with water and drank quickly. The food poisoning symptoms went away within a couple of hours. This one dose was enough to remedy my food poisoning, but others report having to take this dose several times within a day before finding relief.

Charcoal is not a substance I would take regularly, as it can cause constipation and block mineral absorption if it is taken when it is not needed. Also, it can’t be mixed with dairy products or many foods, as they lower its effectiveness. Charcoal can also cause dehydration in large doses so it is important to consume enough water when charcoal is consumed.

How Does Activated Charcoal Whiten Teeth?

First, please excuse my weird smile in those pictures and the bad lighting in my bathroom… I was  trying to show all of my teeth (I don’t usually smile like that! 🙂 ).

As I said, since the powder stains everything, I had always worried that it would do the same to my teeth (one of my kids dumped it in the kitchen one time and it does stain tile, grout, clothes and shoes… just so you know!).

I did some research and found out that even though it temporarily makes the mouth look extremely black (see picture above!) it has the same effect as it does when ingested: it pulls toxins from the mouth and removes stains. (Fair warning: when you open your mouth, it is completely black and rather scary looking! Right after I did this the first time I was intensely worried that it would stain my teeth.)

To my surprise, all of the black washes away and it makes your teeth feel extremely clean and smooth. After a few uses, my teeth were noticeably whiter too (you can sort of tell in the picture above… the lighting didn’t do it justice though).

Further research I’ve done on this showed that activated charcoal can actually be helpful in changing the pH and health of the mouth, and as such is effective in preventing cavities and killing the bad bacteria present in tooth decay and gingivitis. For this reason, I now use it as part of my remineralizing protocol for teeth, along with my remineralizing toothpaste.

Of course, it is important to check with your own doctor and dentist before using this or any substance internally or orally.

How I Used Charcoal to Whiten Teeth

Dip a clean, wet toothbrush into the powdered charcoal (or dump a capsule of charcoal on the toothbrush). Lean over the container of charcoal and quickly put the charcoal covered toothbrush in the mouth (this is to protect your sink). Brush in small, gentle circles for 2 minutes, spit carefully and rinse really well.

Your mouth will feel amazingly clean…. your sink, not so much! Use as often as needed. Readers have also reported mixing the charcoal with water and swishing with it for two minutes.

Where to Get Activated Charcoal

Most natural health stores carry activated charcoal in loose powder or capsule form and it is also available online. I keep both the powdered and capsuled forms on hand in case it is needed for poisoning and I keep the powder in a small glass jar for tooth brushing. Make sure that the charcoal is from wood or coconut sources and not petroleum-based.

It is also very important to note the difference between food/supplement grade activated charcoal and other forms of charcoal. I hope it goes without saying, but I’ll say it to be safe:

Do not use any other form of charcoal besides activated charcoal in your mouth or internally. Do not use leftover charcoal from a BBQ grill or charcoal briquettes. Do not use charcoal pencils or any other type of charcoal.

Charcoal Whitening FAQs

I’ve received some of the same questions about this process multiple times so I’ve asked friends who are dentists and done further research to try to answer them:

Does it Stain Crowns/Veneers/Fillings?

I don’t have any of these in a visible place to be able to share any firsthand experience. Readers have reported trying this method of teeth whitening without a problem on these types of surfaces, but I’d definitely recommend checking with your dentist before using this or anything else if you have any of these.

Does Charcoal Pull Calcium From the Teeth?

Another question that I’ve received often. As always, check with a dentist if you have concerns about your teeth and before using any substance to whiten them. From the research I found, charcoal binds mostly to organic compounds and not minerals so there should not be a concern of it pulling calcium from the teeth.

Is Charcoal Too Abrasive for Teeth?

This is one concern that some dental professionals have expressed about whitening teeth with charcoal and it is a valid concern. I was unable to find any research that evaluated how abrasive charcoal was to the surface of the teeth. A suggestion from my friend who is a dentist is to use the charcoal without brushing or scrubbing.

She suggested that anyone worried about charcoal being abrasive or anyone with sensitive teeth could accomplish the same thing by simply dabbing charcoal onto the surface of the teeth with a finger or cotton swab and letting it sit on the surface of the teeth for two minutes before swishing with water and rinsing.

This would allow the charcoal to come in contact with the surface of the tooth long enough to remove surface stains without the brushing or scrubbing action that could be too abrasive.

What Kind of Stains Does Charcoal Work On?

My dentist friend also advised me that activated charcoal will only work on surface stains that it is able to bind to, especially those from drinks like coffee and tea. This is because it creates its absorbent properties which allow it to pull these stains from the teeth. It won’t usually work on teeth that have yellowed from antibiotics or other internal problems.

Whiter Teeth? An Update

After using the activated charcoal for a few months and swishing with diluted regular 3% hydrogen peroxide when I remember (at the recommendation of a dentist) I am really happy with how white my teeth have become!

Here’s a recent picture (cropped from a photo at a family wedding so it looks pixellated). Notice the difference?

What do you think? Am I crazy? Would you try it for whitening your teeth?

Activated charcoal is a simple way to naturally whiten teeth and promote oral health at home.
