Although it has a strong black color, active charcoal whiten your teeth well and removes the yellow stains from tea and coffee.
If you regularly clean your teeth with active charcoal, you can prevent the formation of tartar and cavities.
Once a week use the following method:
Crush one tablet of active charcoal and then use the toothbrush on which you had previously put the toothpaste and dip into the powder. So brush your teeth for a minute or two, and if necessary, put the brush back in the active charcoal powder. You can also use only active charcoal, without toothpaste, but avoid this if you have a thin tooth enamel so you do not damage it.
