Consumer Reports tested to see how well eight at-home teeth whitening kits work. The kits cost anywhere from $17- $50.

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

There are kits that use strips that stick on and strips that dissolve. Other kits use trays, including 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 that the i-White kit actually whitened teeth the least of all the kits tested," Williams said.

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

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

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

The two runners-up were: Listerine Whitening Quick Dissolving Strips at $24 and Crest Whitestrips Premium for $35.

"If you want to reduce stains on your teeth, go easy when it comes to drinking tea, coffee, colas, red wine, even clear sodas," Williams said.

Be aware that all the kits Consumer Reports tested caution the product may cause temporary tooth and gum sensitivity and that did happen to some of the testers
