How do whitening toothpastes work?

ANSWER

All toothpastes help remove surface stains, because they contain mild abrasives. Some whitening toothpastes contain gentle polishing or chemical agents that provide additional stain removal effectiveness. Whitening toothpastes can help remove surface stains only and do not contain bleach; over-the-counter and professional whitening products contain carbamide peroxide or hydrogen peroxide that helps lighten the color deep in the tooth. Whitening toothpastes can lighten the tooth's color by about one shade. In contrast, prescription strength whitening conducted in your dentist's office can make your teeth three to eight shades lighter.
