Crest Whitestrips
From Wikipedia, the free encyclopedia
Crest Whitestrips is the name of a tooth whitening product made by Procter & Gamble.
Introduced in 2001, Crest Whitestrips has been used worldwide by selling to over 14 million homes.[citation needed]
The active ingredient is hydrogen peroxide. The product is used by sticking a strip to the teeth and usually has some minor to moderate effect. It is most effective on yellow teeth, but less so or almost ineffective on gray teeth.[citation needed]
Like most teeth whiteners, a side effect of Whitestrips is a slight stinging sensation in the gum that may be occasionally piercing. Occasionally white spots will appear on teeth, but only last for a couple hours.[citation needed] If Crest Whitestrips come in contact with clothing or skin, bleaching will occur. Crest Whitestrips are not recommended for children under 12.
Priced around $25 USD, Regular Whitestrips are advertised to whiten teeth in 2 weeks. Conversely, Whitestrips Premium (priced around $30 USD) are advertised to whiten teeth in as little as 3 days. The effect can last up to a year after the application.[citation needed]
[edit] Ingredients
Crest Whitestrips contain Water, Glycerin, Hydrogen Peroxide, Carbomer 956, Sodium Hydroxide, and Sodium Saccharin.
