I will admit, this charcoal teeth whitener has shocked me totally. I have been using it for two weeks now, and the results are mind flowing after every single usage. It is quite easy to use, you only need to get a small portion of the tooth powder, then dip a wet toothbrush into the jar, then brush your teeth for around 2 to 4 minutes, then rinse your mouth with clean water. You can use it in the shower to make the cleaning much easier. Plus, it is all-natural and organic. Definitely recommend, great product!!!
