Apple cider vinegar is a common cooking ingredient with a variety of health benefits, including the ability to whiten your teeth.
The vinegar is made from fermented apples, and when used as a teeth whitener it not only gently removes stains but also kills bacteria.
To use, dilute a half teaspoon of apple cider vinegar in a cup of water and gargle with it before brushing your teeth.
Be careful not to over-do it. Like any whitening substance, too much can weaken the enamel on your teeth. Once a day is plenty, and check with your dentist first.
