Crest is a household name when it comes to dental hygiene.
The Crest Whitestrips are advertised on television, in the newspapers, and are relatively easy to find in stores as well. This system is very similar to the boxed Whitestrips you get in most drugstores, with the addition of a whitening light that helps to speed up the whitening process, so you can see whiter teeth in less time.
To use, you peel the strips, place them on your teeth for an hour, and use the light to boost the whitening process. After about 10 days, you will really see the difference the product makes.
These strips aren’t much different from the Whitestrips you get in stores; with the addition of the light, and perhaps some minor style changes, they are essentially the same. Crest Whitestrips are also a bit of an expensive product, and you do have to buy refills if you want to continue whitening your teeth. There is also the added side effect of tooth sensitivity. Eating and drinking may become difficult during this whitening treatment.
