I've been using Aquafresh whitener trays with pretty good success...but I have little staining. I gave them to my BF, who has had minimal success, but he has much heavier staining.

What does everyone else use OTC? (over the counter). thanks~!

I'm curious as well I've tried the Crest whitening strips - but they make my teeth painfully sensitive

I've used the crest whitestrips and am pleased with the results. Yes they do make my teeth more sensitive while I am using them, but I plow ahead and get it done anyway.

The Crest Night Effects are wonderful! It's a paste instead of strips, but you put it on at night, then next morning brush it off and in 14 days they are beautiful!

Which Crest White Strips... aren't there about 4 different kinds?

Has anyone heard anything about the Rembrandt system? it's a bit more involved (and spendy)...before I put out the $$ for it, I'm trying to gather more info.
