Activated Charcoal Teeth whitening, how to use, Before After Results, Side Effects & Reviews

Strong desire to have teeth whitened pushes many people to limits that you dare not endear. However, with the social media promising more hope, some of these methods have gone viral such as the use of activated charcoal for teeth whitening. Read on to find out how this method works, results and possible side effects

Why Activated for Teeth Whitening?

Everyone desires teeth that are sparkling white. You probably know by now that tooth color is primarily determined by dentin when it reflects light. This is further modified by the enamel when it absorbs and scatters light.

Note that if you desire any change in color of your teeth, then they better be bare and not crowned or cusped. It is believed that everything in this universe has a yin and yang. Just as there is day and night and man has left and right, front and back, the use of black to make white is unquestionably contradictory.

However, for the existence of one, there has to exist its opposite and this is what the ancient Chinese philosophy postulates.  It further says that they are complementary and interconnected. Here’s the yin and yang that you might want to ponder on, whether brushing your teeth with black toothpaste can actually increase their white.

Before we shade the light on this matter, you need to understand what activated charcoal is. Firstly, it is not the normal charcoal but rather one that is reheated and oxidized and that exhibits properties that allow it to adsorb materials(highly porous).

Surprisingly enough, a gram of activated charcoal is able to help adsorb surface worth 32,000 sq ft. This powerful property of activated charcoal has made it a wonder in the medical field with its use as an adsorbent material in cases of an oral ingestion of poisons such as paraffin.

Care should be taken however to note that there are three main types of teeth discoloration inclusive of intrinsic, extrinsic and senile discolorations. Extrinsic discoloration is mainly caused by intake of coffee, soda or wine among other foods and drinks.

Habits such as smoking and taking alcohol are also causative agents. On the other hand intrinsic refers to an onset in the inner layers, particularly the dentine. When it is affected, it darkens and exhibits a yellow color and this falls culprit of too much fluoride especially during your childhood.

There have been other causes such as tetracycline regimen at the age of 7 years and younger when the teeth need to develop

Intrinsic – mostly causes by coffee, soda and wine among other food and drinks that may cause staining. This is alongside habits like smoking

Extrinsic – discolors the tooth from the inner layers, from the dentine. This layer may darken and exhibit a yellow colour. Among the causative agents include too much fluoride during childhood when teeth are growing and developing.

When mothers in their second trimester take tetracycline antibiotics or administer them when you are 7 years younger, teeth discoloration may occur. Other forms of discoloration occur due to internal bleeding of a permanent tooth and genetic predisposition.

Senile – with age the dentine yellows with time as the enamel gets thinner. This may be caused by reduced care of the teeth hygiene by the old. Also, due to slow replacement of the white part, the dentine.

Teeth generally become more darkly pigmented with age and exposure to such materials as tea and coffee, and it has long been a goal of dentistry to provide a means to safely and effectively reverse this darkening process. Historically there are two approaches to the problem.

The first involves removing pigmentation that has adhered onto the surface of the teeth. This is commonly achieved through the use of abrasives, sometimes augmented with solvents.

While rapidly effective, these techniques have the disadvantage of only being able to remove extrinsic stains, leaving all internal pigmentation unchanged. Thus, the whitening effect is extremely limited.

A more recent innovation involves a method of using oxidizing agents to penetrate into the tooth structure and bleach out the undesired pigmentation. The active agents are usually either weak solutions of hydrogen peroxide or carbamide peroxide, which is more stable than hydrogen peroxide.

While effective on both extrinsic and intrinsic discolorations, one major problem encountered with this second approach is the enormous amount of treatment time needed to gain adequate penetration of the tooth structure by the whitening agent.

At present, the method of application of the whitening agent utilizes either custom or stock trays that are shaped to hold the bleaching agent against the teeth to be whitened. These trays are then filled with the peroxide, and worn for long periods of time, sometimes even overnight.

After a series of lengthy treatments, the teeth will usually begin to show the desired whitening effect. The length of these treatments can be discouraging and increases the cost. It is therefore desirable to find a method to more rapidly whiten the teeth.

Studies by Evidence Based Medicine, The American Dentists Association and The Food and Drugs Administration have not approved the use of activated charcoal as a tooth whitener. The FDA has approved its use in other indications and therefore this makes it an off-label use.

Whether this may form part of the reason why people are turning their options to black toothpaste lies on the following considerations:

1.      There are activated charcoal toothpastes in the market

You might think that this is a totally strange idea that whitens teeth until you meet it on the shelves of the supermarkets.

One, ‘Black is White toothpaste’ manufactured by Curaprox Inc. has in it activated charcoal aimed at whitening the teeth. In addition to whitening, it is also able to remove stubborn stains on the teeth.

It has other properties owing to its ingredients such as nano-hydroxyapatite. This ingredient particularly is responsible for the deposition of the calcium complex that forms your bone and teeth.

2.      Activated charcoal has adsorptive properties

is a known powerhouse that will help you suck impure matter on your teeth through adsorption. It basically does this by providing a porous surface on which the impurities can be adsorbed.

So, what it does, is leave the teeth cleaner than before. This known mechanism was approved by the World Health Organization in the 1900s but not on discolored teeth however as an indication.
