2 Best Teeth Whiteners -- and the 4 Worst for 2014
See which teeth whitening products made our testers smile -- and which made them want to flee to a dentist
Why: With well over 60 reviews, most of which are negative, Aquafresh White Trays land in the second-to-worst spot on our list. You use the product by placing gel-filled whitening trays on your upper and lower teeth and keeping them in for 30-45 minutes, once a day for up to a week. Readers had numerous complaints with the product, saying that the trays are uncomfortable to wear, the gel tastes bad, the formula irritates sensitive gums and sometimes even turns them white. Plus, the final results are inconsistent. Though some users did end up with whiter teeth, most could not get past the uncomfortable, messy experience of using the product. "Wouldn't recommend it to anyone," said one user, who reported that the tray didn't stay in place, the gel was "nasty," and it generally "didn't work at all." Yikes.
