This method could replace teeth whitening treatments that we all know
It seems strange to use black powder in order to whiten teeth, but it really works. Charcoal is effective in absorbing tannins. Tannins are compounds that are found in tea, herbal tea, coffee, snuff, spices, wine and other food. Another good reason why to use charcoal is because it helps to set the minerals (such as calcium) in teeth, it can’t damage the enamel of the teeth, so you can use it every day.
How to use it:
The procedure is very simple. Carefully open one capsule of activated carbon (that you can find in pharmacy) and pour it into your mouth. Use a toothbrush, and assign it only for this purpose. Brush teeth thoroughly for about 10 minutes, than spit and rinse thoroughly. After this, brush your teeth as usual. You should notice dramatic change within a week.
