Well even after saying this product does not work well I researched a bit more . If you have not had your teeth professionally cleaned recently this product will not work as tartar and plaque will not whiten. So I wasted my money then, now that I have had my dentist clean my teeth I will try again

Fonctionne vraiment bien...seulement dommage que ça soit si cher!

love these whitestrips. saw a difference within a few days

I am buying these whitestrips annually. It saves soooo much money. You just don't need to go to the dentist anymore to make your teeth look whiter. I know, that some people are thinking that this is costly, but you should just try it and see the result.

I used up the whole box but my teeth is still yellowish. Maybe it is marginally whiter, but it is definitely not worth the money. I also found that some strips do not stick well to teeth, so it is like falling off the whole time.

I found that the Crest White strips caused major gum soreness. However, the product does as promised in giving you the white smile you've always wanted. I would probably use this product if I was going to a big event where I know I'll be photographed. I don't think I would use it unless it was necessary because like I said, the gum pain is severe, it would irritate you on a frequent basis. I tried taking a pain reliever to lessen the pain, it did help somewhat, but it is something to consider when purchasing the product. I thought the price was little high because it is cheaper than an actual dentist visit and you get the same results.
