2 Best Teeth Whiteners -- and the 4 Worst
See which products made our testers smile -- and which made them want to flee to a dentist
Why: Readers were extremely disappointed with this ineffective, frustrating whitening kit. Here's how it's supposed to work: you apply a whitening gel to plastic applicators, which are promised to conform easily and comfortably to your teeth. You leave the plastic trays in your mouth for four 20-minute intervals, washing your mouth with water in between. Sound like trouble? Most readers found that it was. "No matter how well you get the whitening trays to conform to your teeth and how long you leave it on, it barely whitens your teeth at all," one reader complained.
But even those who did receive slightly whiter teeth at the end of the treatment ended up with worse problems. "Although, it did whiten my teeth by 2-3 shades, it left me with horrible damage to my gums. If I could give this a zero I would!" another reader reported. Plenty of reviewers experienced similar gum and teeth irritation. Affordable or not, approach this product with caution.
