<h4 class="dechead">On One Hand: There Might Be Some Change
Many studies have been performed on whitening toothpastes and some indicate a minimal change in tooth color. In 2006, a Consumer Reports study resulted in a slight endorsement of Colgate Ultra Brite All In One Advanced Whitening toothpaste. It was seen as the only one of the 41 tested toothpastes to show any significant whitening benefit.
On the Other: They Mostly Remove Stains
A study backed by the Daily Mail in England showed that no whitening toothpaste fared any better at whitening teeth than ordinary toothpaste. At best, some of the whitening toothpastes eliminated stains, which actually is all many of them claim to be able to do. Removal of stains can make teeth appear brighter, but it doesn't change their color.
Bottom Line
Whitening toothpastes are considerably more expensive than ordinary toothpaste but have not shown marked results. If you want to whiten your teeth, professional whitening performed by a dentist is the surest bet.
