Tooth Whitening: Is Cheaper Better?

Lately, I've been thinking of having my teeth whitened at Brite Smile, but the idea of spending a few hundred dollars for gleaming chompers doesn't sit so well with my inner cheapskate. So this morning, I asked my dentist which method he recommended.

"Honestly," he said—and I paraphrase—"I'd just get some Whitestrips." He went on to say that while Brite Smile would give me slightly better results than Whitestrips, he didn't think the difference was worth the significantly larger cost.

He's not the only one. My former dentist once told me the same thing: Whitestrips are effective and relatively inexpensive. Thought you all might like to know that in my completely informal survey, the at-home stuff gets the thumbs-up from dentists. It's been a few years since I've done Whitestrips, so I'm curious: Do you think they work? Or would you rather save up and do something like Brite Smile?
