Received a free sample in the mail from Proctor and Gamble and tried it for the full 2 hours - First I LOVED the way they clung to your teeth, did not move around at all and you had to literally peel them off after! This was a huge improvement from 30min versions I had tried before! I did see a significant difference in the degree of yellowing on my teeth but not as great as hoped (as they are bad lol) After a few treatments I think these would really do the trick! You would need to use multiple strips to cover your back teeth as well.

I've had my teeth professionally whitened many years ago and loved how beautifully white my teeth were. I don't have that kind of money to spend now as a Mom with a family so I thought I'd give these a try. Sadly, it was not a good experience. I suffer with very sensitive teeth and keep it under control using sensitive toothpaste. Using the Crest White strips brought all the painful sensitivity right back and it took a long time for it to go away. I would have loved for these to work because they are fast and cost effective but I think I'll have to spend the money and do it professionally again if I want whiter teeth!

I have never had more sensitive teeth in my life !! I will say this, the stuff works. It really does, it made my smile incredibly white and people noticed... However, I didn't want to smile. Because, god forbid a gust of wind land upon my teeth!! I was unpleasantly surprised to have at least a week of overly sensitive teeth --from the chemicals I'm assuming. They do say pain is beauty.. But is paying an arm and a leg also beauty? I'm left wondering if the plain-jane store name brand might have given me the same result for a fraction of the cost. If I'm going to have to suffer with sensitivity I'd at least like to save a dollar or two

after so many years of wine,coffee and many more stuff i dont have a nice white teeths so i give a try to this whitestrips and wow i see a little difference right away after the first use so it good

Love them...they work awesome...will purchase in the future.

This product has been one that I have tried to use to keep my teeth white. These whitestrips do work well but the pain you'll endure after is totally not worth it! Left my teeth feeling sensitive for a few days after! Save the money & try something else!

Did not work well for me after 3 hours on

I was very excited to try the white strips! My gums hurt after for 2 days and they were so tender! I was so disappointed and thought i was going to have to go to the Dr.'s
On a good note i did visually see whiter teeth!

I was given this as a sample and i was excited to try it. I left it on for the recommended time but i experienced a lot of sensitivity after i took the strips off. took my teeth two days to recover! i would never use them again!

Tried these and I could see some difference but they make my teeth super sensitive afterwards. They're easy to use and keep on but I'm not sure I'd try them again because of how sensitive they made my teeth.
