Activated Charcoal Toothpaste – Can It Really Whiten Teeth?

Charcoal ToothpasteActivated Charcoal, What is It?

Charcoal is simply the carbon, along with some ash, that is left over from burning something up where the water has been removed, usually through fire. Charcoal is usually made by heating wood or other plant matter in an oxygen deprived environment. This used to be done by forming a pile of logs around a chimney that is also made of logs and then covering it all with dirt and straw so that no air could get in. The logs were set on fire by putting something combustible through the chimney. The logs would burn very slowly over the course of about a week and would turn into charcoal. Modern methods use sealed metal containers or other such implements that make it quite a bit more efficient to make charcoal.

Charcoal can come from pretty much anything that was once alive, either plant or animal. Charcoal that is used in activated charcoal and is sold and marketed for that purpose generally comes from hardwood trees.

Some vegan/vegetarians get concerned at this point about the source of charcoal, but in my research I have never come across a company that sells charcoal for human consumption that uses anything but plant-based products as the base for their charcoal. I have never found a company that uses animals and probably never will because it would be a very inefficient source for producing charcoal. Animals have a much higher moisture content than a tree or most plants, which means that they will produce less charcoal per pound that goes into the fire. So vegans and vegetarians can rest easy. If for some reason you are still concerned check with your local supplier or health food store or call the company directly.

Charcoal is used mainly as a fuel for cooking throughout the world. In westernized countries we generally only use charcoal for bar-b-que (charcoal briquettes!).

Charcoal that is used for your bar-b-que cannot be used for toothpaste and teeth whitening. Not because it is chemically different, though most briquettes have other chemicals added to make them burn better so in that way they would be chemically different. The important difference is that the charcoal has not been activated.

Activated charcoal, sometimes called pulverized charcoal, is charcoal that is put through either a physical or chemical process to make it have many small pores. These pores enable the charcoal to adsorb chemicals and other compounds.

Adsorption is a process where a gas or liquid adheres to a surface. This is different from absorption which is a gas or liquid entering a bulky mass, such as a tissue absorbing water. Because activated charcoal has many micro pores there is a large amount of surface area to enable the adsorption process. How much surface area does activated charcoal have? In one gram there is approximately 2 square meters of surface area. This is the miracle of charcoal, so much surface area to adsorb unwanted chemicals, bacteria and stains on teeth.

Using Charcoal as a Toothpaste

Our teeth always become stained from coffee, tea, berries and so many other things. Activated charcoal can help you with this. It can make your teeth white and shining and allows you to remove all these stains. It also brings good oral health and it does that by changing pH balance in mouth. This helps in prevent cavities, bad breath and diseases of gum.

While it may seem that using charcoal on your teeth would bring the opposite result of whitening charcoal is actually a very effective tooth whitener and beneficial as a toothpaste additive. The dental industry is getting rich on a variety of teeth whitening products. White teeth is something that is very desirable, especially if your teeth have significantly yellowed from smoking, coffee drinking or other reasons. Charcoal is a very low cost (compared to packaged whitening products) method to whiten your teeth. You do need to be careful about overusing charcoal or any whitening product on your teeth because you do not want to wear down your tooth enamel.

It absorbs toxins and wave on your teeth and in this way it makes your teeth white. This use is very cheap and not at all expensive also it’s an easy solution for bright smile. Do not forget to protect your things you are putting it at, as it can stain the fabrics and cement.

Want to make your teeth white without using any other chemical, all you have to do is wet your tooth brush and dip it into powder of activated charcoal. Then brush your teeth like you do normally, but pay special attention to the stained areas. Sip, swish and spit the water through mouth. Rinse it thoroughly until the spit is clear and clean. If you want best results, you should brush your teeth with activated charcoal more than two times in a week. If you have crowns or caps, remember that activated charcoal can stain them. And if you think using it is making your teeth sensitive, stop using it right away.


To be honest, I was pretty skeptical. Like most everyone else, I heard about using activated charcoal toothpaste from Doctor Oz. I thought, what the heck, I’ve had gum problems in the past, I’ll give it a try.

I ordered a tube of SUMIGAKI JAPANESE CHARCOAL TOOTHPASTE off Amazon, it seems to be the most popular.

The paste is indeed black in color, that takes some getting used to. The taste is not what you’re used to from traditional toothpaste. It has a hint of fruity flavor, slightly grape, but very minty. Some people have reported they do not like the flavor, but I found it quite pleasant. The minty flavor and sensation most definitely lasts longer than colgate etc. My wife says that she immediately noticed an improvement in my breath.

As for whitening my teeth and overall gum health, I’m happy to report positive results there as well. After about 2 weeks, I thought my teeth were several shades whiter. My wife agreed. But the final verdict was up to my dentist,

I went to see his office last week for a teeth cleaning. The Dental Hygienist wanted to know what I was doing differently with my teeth. It was much cleaner around my gum line and I had far less plaque than usual. I told her about the charcoal toothpaste I was using, When the Dentist came in to see me they both wanted to know where to get the toothpaste.
