8 Simple Ways to Whiten Teeth at Home
Use Activated Charcoal

Activated charcoal is quickly becoming one of the more famous home treatments for teeth whitening. The granules in charcoal are highly porous, making them highly capable of binding and absorbing bacteria and tiny bits before they stain or discolor the teeth. To whiten at home, mix one teaspoon of activated charcoal with water to make a paste and brush, paying close attention to stained parts of the enamel for maximum effect. Leave this paste on for two to three minutes, then rinse the mouth until all of the charcoal is gone. Using this treatment a few times a week is proven to whiten teeth and produce an overall brighter smile.
