Description
Crest Whitestrips were introduced in 2001. They have become the number one selling teeth whitening product in the US. The product is used by placing a disposable plastic strip directly onto the teeth that contains an enamel safe whitening gel. It is reported to be most effective on yellow and heavily stained teeth.
Since 2010, the new '3D' range was introduced. The new 'Advanced Seal' is a technological advancement from the older Crest Whitestrips. The strips are now non-slip, and also whiten more teeth in the mouth with each strip being larger in length. These are available with the strongest retail 3D Advanced Vivid and 3D Professional Effects Whitestrips.
US Dentists also offer a specialized Crest Whitestrips called 'Supreme', which is 80% more effective than any retail versions due to the higher concentration of Hydrogen Peroxide.
Possible side effects from Whitestrips usage include gum irritation and white spots on the teeth for a few hours after use. Sensitivity can also temporarily occur. Whitestrips can also have a bleaching effect if they come in contact with clothing or skin. Whitestrips are not recommended for children under 12.
The active ingredient is hydrogen peroxide.
According to a 2009 article in The Washington Post, Consumer Reports found Crest Whitestrips Supreme to be the best of the eight teeth whitening products it tested. This product was the most expensive kit tested by Consumer Reports.
