Crest Whitestrips Supreme
Crest Whitestrips Supreme, first introduced in 2003, are the strongest Whitestrips available, but they are not availalbe over the counter.
These Whitestrips have a 14% hydrogen peroxide content, making them the most intense of the teeth whitening products. They come with 84 strips, 42 each for the upper and lower sets of teeth, and are designed to be worn for 21 days.
Crest Whitestrips Supreme are recommended for users with the most intense stains, but the users must not have sensitive teeth, as this product can and likely will cause some sensitivity.
We award this product four stars because of it works very well; its performance is simply unmatched. Supreme Whitestrips will dramatically whiten your teeth. It did not get a perfect score because, like most other Whitestrips, it sometimes slides off the teeth, making it difficult to use, and its non-availability over-the-counter makes it harder to purchase.
