Do whitening toothpastes really work?
Whitening toothpastes, like all other toothpastes, contain carbamide peroxide to remove surface stains. Whitening toothpastes may have additional polishing agents and special chemicals that are more effective against stains than regular toothpastes. While whitening toothpastes can make your teeth appear a little lighter, by getting rid of stains, they do not actually bleach your teeth. Whitening toothpastes are ideal for people who smoke, drink coffee and tea and eat certain foods that can stain your teeth.
Whitening toothpastes are also good to use after you have undergone a teeth whitening procedure to keep surface stains from building up on your teeth. If you decide to use a whitening toothpaste, be sure that it contains fluoride for extra protection against tooth decay.
