I swear by these whitening strips. I've been using them twice a week for the past couple years and get compliments a lot on how white my teeth are. I think they work just as good as professional whitening done by a dentist

This product by far works!! I purchased the "tray" and whitener from my dentist previously. Crest 3D Whitestrips are easier, less messier and convenient!!

I love these my teeth got so many shades whiter. I use them quite often and they don't compare to any other teeth whitener. However I do think they are quite pricey but I'm overall satisfied.

Great whitening results in a short amount of time. May cause some sensitivity if you have sensitive teeth but you can use it every other day instead of every day to minimize any side effects.

I saw a wonderful difference in my teeth after a week! so I stopped and now I am just saving them for when it gets closer to holidays for the perfect smile!(:

the white strips work great! buttt they make your teeth extra sensitive. every once in a while when i'm using them, it shocks a nerve in my teeth, then it hurts every time i eat/ drink something cold. i recommend them if your teeth are strong

I recently used these and I was not impressed with them. I didn't notice much of a difference on my teeth. I have used the one hour express and those are good!

Still using and waiting for results! I think that in order to see results it has to be used completely! I have heard my teeth are whiter so I think it is working. Can be a little pricey but cheaper than professionally whitened.

very good product. might make your teeth a little sensitive, but it's a good product and does the job, just follow the instructions very well and don't leave them on long

This ones are a good option if you are looking for a quick whitening kit at home they really do work and I been using this ones for quite some time now.
