Crest whitestrips are about as good as you can get OTC. You need to go to a dentist to get something stronger. The one visit whitening treatment works, but it often leaves your teeth very sensitive. I recommend the system where you get custom made trays to put the bleach in and wear at home. You usually get pretty good results with a week or two of one hour a day applications.
Yo J-Money, what kinda of OTC teeth whitener do you recommend I use to get my chicklets sparkly white? These Crest Whitestrips don't do anything..
