LED Teeth Whitener

CLAIM: By using the hydrogen peroxide with the LED light, you can whiten teeth better (up to six shades), faster (just 10 minutes, three times), and with less irritation than you'd experience with some standard strips.

EXPERT OPINION:"Hydrogen peroxide will lift stains," says New York dentist Pia Lieb. But the light source is straight, not "semi-lunar" like teeth, she says, so some chompers may get more light than others.

OUR VERDICT: Maybe not worth all the drooling. After 10 minutes, our lips ached and our teeth looked only a little brighter.
