Top-Rated Tooth Whitener

Would you like whiter teeth but don't want to spend hundreds of dollars at the dentist's office? Consumer Reports tested eight drugstore kits, including some that are heavily advertised.

Do you dream of having teeth as white as models? Crest hopes you do-aggressively advertising on TV and on Facebook to promote its Whitestrips Advanced Seal.

Crest promises it will give you a dramatically whiter smiler.

Listerine says its Whitening Quick Dissolving Strip "simply dissolves to noticeably white."

And i-White claims to provide "dentist office results."

Consumer Reports tested to see how well eight-at-home kits work.

They cost anywhere from $17-$50.

"We had over eighty staff members try out one kit each," says staffer Gayle Williams.

There are kits that use strips that stick on-and strips that dissolve.

Other kits use trays, including this one from i-White.

It has a battery-operated light designed to accelerate teeth whitening, but it didn't do so well.

"It turns out the i-White kit actually whitened teeth the least of all the kits tested," said Williams.

Consumer Reports uses a device-a colorimeter-to assess staffers' before and after tooth color.

"Don't expect dramatic results." said Williams. "None of the kits offered a Cover Girl white smile."

But the $50 Crest Whitestrips Supreme did outperform the others-rating very good.

It's available online.

Be aware that all the kits Consumer Reports tested caution the product may cause temporary tooth and gum sensitivity, and that was the case for some people in the tests.
