Lemon : Regular Cleansing of teeth

Lemon can be used in the regular cleansing of your teeth. Keep your eye out for a toothpaste containing lemon as one of the ingredients, or add a drop of lemon juice onto your normal toothpaste. Some people also rub their teeth with the outer shell (the inner side touching your teeth) of a lemon after removing the juice. But be careful, lemons are highly acidic, so if your mouth starts burning, rinse your gums and mouth quickly with water.
