8. Crest Whitestrips Supreme Professional Strength

Crest Whitestrips Supreme provides an aggressive whitening solution by offering the highest concentration of whitener ( 14% Hydrogen Peroxide ) in any Whitestrips. So it offers the greatest potential for achieving dramatic color changes. 30 Minutes twice a day, you will have 3 shades lighter after 10 days. However, the elevated concentration of whitener makes the likelihood of experiencing side effects greater than other Whitestrips. It is not to be an entry-level product nor a prudent choice for the first time user. We recommend it to people who require stronger whitening as you have heavily stained teeth and not sensitive.
