- Whiter teeth in as little as three days
- Very easy to use
- Dentist recommended and approved
Users report some teeth sensitivity and soreness with repeated use. Additionally, be aware that the strips are only large enough to cover 4 to 5 teeth at a time. So if you're looking to whiten all of your teeth, not just those in the front, the box of strips may not last as long as you would think.
Results: Crest claims that Crest Whitestrips will remove 10 years of tough, set-in stains and whiten teeth 25x better than any leading whitening toothpaste, and boy do they deliver. Regardless of the few complaints regarding side effects and time frame, reviewers can all agree that this product truly works. Crest Advanced Seal Technology will hold the strips in place throughout the duration of the treatment, allowing you to talk and even drink water while whitening. Additionally, Crest Whitestrips are one of the only whitening remedies that does not require using a thermoform tray! Effective and convenient. Need we say more?
Time Frame: For just 30 minutes a day, Crest Whitestrips will begin to brighten your smile in as little as three days! Though some reviewers did not report a noticeable difference for five to ten days, everyone can agree that you will see fabulous results after using just one box of strips.
Side Effects: Since this product does contain hydrogen peroxide don't be alarmed if you do experience some tooth sensitivity or gum soreness - totally normal. However, if you're someone with severe dental sensitives, you may want to consult your dentist before giving this product a try.
Price: At just under $30 for a box of 28 strips (14 treatments with upper and lower), this is one of the most cost effective whiteners on our list! Totally worth the investment.
