Activated charcoal is a highly absorbent substance. It
removes toxins when they adhere to the surface of the charcoal. It is not
absorbed by the body, but passes through the GI system, so chemicals and toxins
adhere to it, which then pass through the body and are expelled by the digestive
system.
Even though it temporarily makes the mouth look extremely
black, it has the same effect as it does when ingested: it pulls toxins from
the mouth and removes stains. All of the
black washes away and it makes your teeth feel extremely clean and smooth.
Activated charcoal is effective in preventing cavities and killing the bad bacteria present in tooth decay and gingivitis.
How to USe Charcoal to Whiten Teeth
Dip a clean, wet toothbrush into the powdered charcoal. Lean
over the container of charcoal and quickly put the charcoal covered toothbrush
in the mouth (this is to protect your sink). Brush in small, gentle circles for
2 minutes, spit carefully and rinse really well.
Your mouth will feel amazingly clean. Use as often as
needed. People have also reported mixing the charcoal with water and swishing
with it for two minutes.
