Crest Whitestrips Pro Effects
Crest Whitestrips Pro Effects were originally called “Crest Whitestrips Premium Plus,” which was introduced in 2005. But, that name wasn’t catchy enough, so Crest decided in 2008 to rename it to “Crest Whitestrips Pro Effects.”
Still the same product, the Pro Effects Whitestrips contain 10% hydrogen peroxide and are designed to be worn for 10 days – the package comes with 40 strips.
These Whitestrips are stronger than Crest Whitestrips Premium because of the additional 3 days of use.
Crest Whitestrips Pro Effects are recommended for users with darker than normal staining who want an extra three days of whitening to be sure the stains are removed and for users without sensitive teeth. Crest Whitestrips Pro Effects, along with Crest Whitestrips Advanced Seal, are the strongest teeth whitening products available over the counter.
This product gets four stars. It whitens teeth very well but suffers from the lack of adhesion; although its whitening works well, it is difficult to keep on the teeth, making achieving the whitening effect harder to accomplish.
