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.

Famous quotes containing the word description:
“The next Augustan age will dawn on the other side of the Atlantic. There will, perhaps, be a Thucydides at Boston, a Xenophon at New York, and, in time, a Virgil at Mexico, and a Newton at Peru. At last, some curious traveller from Lima will visit England and give a description of the ruins of St Paul’s, like the editions of Balbec and Palmyra.”
—Horace Walpole (1717–1797)
“I was here first introduced to Joe.... He was a good-looking Indian, twenty-four years old, apparently of unmixed blood, short and stout, with a broad face and reddish complexion, and eyes, methinks, narrower and more turned up at the outer corners than ours, answering to the description of his race. Besides his underclothing, he wore a red flannel shirt, woolen pants, and a black Kossuth hat, the ordinary dress of the lumberman, and, to a considerable extent, of the Penobscot Indian.”
—Henry David Thoreau (1817–1862)
“God damnit, why must all those journalists be such sticklers for detail? Why, they’d hold you to an accurate description of the first time you ever made love, expecting you to remember the color of the room and the shape of the windows.”
—Lyndon Baines Johnson (1908–1973)
