In order to have whiter teeth, the only thing you need is active carbon!
Even though it may seem messy and disgusting, many people successfully whitened their teeth using this ingredient.
Being the dark gemstone of natural medicine, charcoal is one of the most powerful natural remedies that help in the treatment of many diseases, from dysentery to post-radiation effects. It is obtained by processing of coal in a steam chamber in which it opens, increasing its surface that can attract more ingredients. There are no side effects when used in the treatment of acute poisoning.
BMSS Addendum: After reading this article, I decided to buy some activated charcoal at my local organic store today. I bought the charcoal in capsule form and all I need to do is to empty the capsule and brush my teeth with the contents. You can find a large assortment of activated charcoal HERE. I’ll report back on my progress somewhere down the road.
