Not the most pleasant tasting approach to whiter teeth. But then again, is there really such a thing as a pleasant tasting teeth whitener?
Pour a small amount of hyrdogen peroxide on your toothbrush along with your regular toothpaste - or mix with water and use as a natural mouthwash. Or, dip your toothbrush in hydrogen peroxide and gently brush your teeth. You can also put some on a cotton ball and swab on your teeth for a minute or so before brushing. This helps make your teeth look whiter within weeks.
