Although i found this product to be somewhat effective in making my teeth whiter, i couldn't continue using them since they would make my teeth so sensitive and actually hurt quite bad!! because of the pain it caused, its obvious to me that they aren't that safe and I'm sure my teeth would be better off without!! I think a natural remedy is where I'm heading with teeth whitening from now on!

Truthfully when it comes to Crest Whitestrips, I kind of feel like they're a huge rip off. I mean, they're good for that instant whitening feel but it really doesn't last more than a few days. For the price of $60, it's just not worth it. The only time I use them is when I get them free through a dentist friend.

I tried the crest white strips and really have nothing good to say about them. They hurt my teeth after wearing them and I saw no difference in the colouring of my teeth. I did fallow the directions and only kept them on for the recommended time frame.

With the price being a bit expensive I was expecting a lot from it and that it would work really well. But it only whitened my teeth a little bit and the bad part was it made my teeth too sensitive especially to cold. It was a bit harsh to my gums as well. It`s an okay substitute for the real thing from the dentist.

Got a free sample of Crest Whitestrips and finally tried them this evening. I couldn't stand the way it felt on my bottom teeth and took that one off after half an hour. I've had the top one on for an hour and a half and can't wait to take it off in half an hour. Do people really wear these for two hours a day? I find the peroxide is making my tongue a little numb. I definitely won't be buying these. Have my doubts over their effectiveness in any case. Thankfully I have fairly white teeth naturally, and see a dentist every six months for a good cleaning.

I love how Crest whitestrips whitens my teeth and how easy it is to remove the strips and apply them. I like to cut them, so not to apply them under my teeth, as I feel that makes my teeth more sensitive. The price is reasonable and comparable to other brands as well.

YEOUCH!!!! I have extremely sensitive teeth and these just about killed me. They literally strip enamel off of your teeth (told to me by my dentist) which exposes stuff you do not want to be exposed if you have sensitive teeth. Sure, they made my teeth white, but was it worth the pain? NOT A CHANCE.

Works really well to brighten teeth - you might need to retouch up later in the year but it's definitely a great product.

watching the commercials you'd think you can walk around town with the product but I found it foams up & since I don't wanna swallow the fluid, I'm constantly discharging into the sink. It does a good job but I'm not fond of the taste.

I use this every once in a while it is easy to use and works great. Wouldnt use it for everyday use and can not replace basic teeth stuff.
