Crest Whitestrips Renewal
THIS PRODUCT WAS DISCONTINUED IN 2008 AND IS NO LONGER AVAILABLE
Crest Whitestrips Renewal, first introduced in 2006 and later discontinued in 2008, are in the middle-range of teeth whitening products.
With a 9.5% hydrogen peroxide content, these Whitestrips are slightly less intense than the Pro Effects and Advanced Seal Whitestrips. Coming in a package with 40 strips, these Whitestrips are designed to be worn for 10 days for 30 minutes twice daily.
Crest Whitestrips Renewal is recommended for users with darker than normal stains and for users without sensitive teeth.
This product gets only three stars; although it works well, there are better over-the-counter choices readily available.
