Charcoal teeth whitening: danger

Our teeth play a vital role in our daily lives. Their good condition is essential for the smile and food. Many solutions can take care of teeth and prevent cavities. The use of charcoal is one of the best known methods for whitening teeth. However, harms have been discovered regarding this solution. So we decided to talk about the dangerous aspects of charcoal teeth whitening.

First of all, what type of coal is it?

This is « activated carbon », the main uses of which are found in hospital emergency departments. Indeed, this substance is renowned for its ability to absorb toxins in case of poisoning or overdose. This same property explains why its use to clean has become more democratic. Thus, many individuals brush their teeth by adding a little charcoal to the brush.

With regard to obtaining activated carbon, it results from the combustion of various species of trees such as oak, poplar and coconut. It is then a plant product, clinically proven to be free of toxic elements. Its formula is similar to swallowed charcoal to treat intestinal disorders.

Why this dangerous aspect?

It is above all the abrasive property of coal that constitutes this dangerous aspect. Its impact is mainly felt at the level of the enamel, but can also affect the root and the inner layers of the teeth.

Thanks to its abrasive characteristic, carbon perfectly removes stains: blackening and yellowing. However, this also leads to the deterioration of the enamel which is the outermost and protective layer of the teeth. Moreover, this destruction is irreversible which results in erosion, thinning and discoloration. When this peripheral layer thins, the abrasive product will reach the inner layers.
