Charcoal Teeth Whitening

Charcoal has recently become a common ingredient in many skin and beauty products as well as teeth whitening products.

How does it work?
Charcoal is very absorbent and abrasive.  So the claim is that it absorbs toxins and removes surface stains.

Is it effective and is it safe?
I haven’t seen any long term studies about it.  But there are many YouTube videos and bloggers swearing by it. It is likely true that it will render whiter teeth.  Just it’s abrasive properties can cause the removal of the surface layer of enamel that is typically stained, but so will sand if we brush our teeth with it.  The trouble with removing enamel is it doesn’t regenerate like skin does.  Thinning enamel, which is the protective layer of the tooth, leads to sensitivity and higher risk for cavities.
There are so many different charcoal products out there and there is no clear regulation or sufficient studies to verify how effective or safe it is.

In my opinion, it’s not worth the risk, especially when there are other safe products that produce good results without the long term damage of teeth.  Charcoal may have a place in dental products but when it is further studied and regulated.
