The secret to whiter teeth, a really clean mouth, fresh breath, and healthy gums is very easy. On top of brushing your teeth at least once a day and flossing, do a hydrogen peroxide rinse daily. To do this use 1 tbsp of hydrogen peroxide and swish it around in your mouth for 10 minites, then rinse your mouth with water. Your mouth will feel great! It is also a good idea to have water be the liquid that you consume the most, which means less soda pop and coffee. Lastly try to consume as little sugar in your diet because sugar rots teeth and causes cavities.
