Still undecided

I bought this at the drug store since they were on sale. I've been using about 3 times a week. Could be the reason why i'm not getting the desired results.
Does leave a bit of tooth sensitivity though (which is nornal).

keep my teeth white

These are the best white strips I have ever used. I drink lots of coffee which results in yellowing teeth so I have been using crest white strips for as long as I can remember. They have always worked well but they use to be slimy and hurt sometimes, not these. They go on and stay on very well NO slime :) and they dont hurt at all. I am not good a committing to wearing them every day but I do put one on once and while to brighten up my smile. one or two applications usually does the trick for me even my dentist always comments on how white my teeth are.

I received a free sample and decided to try it. At first I was dissapointed; My usual brand is Listerine strips, and they are very thin. This brand is very very thick, and they were hard to apply to my bottom teeth at first (which are slightly crooked). Once I finally got the strips on, I found they felt a little awkward and thick, but I got used to them after about 5 minutes.
After a half hour I realized that I had no gummy feeling in my mouth, which I always had with my usual brand. What a nice difference! And they stayed put for the entire hour; no slipping or gooey-ness.
I didnt like having them on for a full hour, as my usual brand is only 30 min, but I am strongly considering swithing just for the ease and comfort of the gooey-less crest ones!

I extensively researched at-home whitening products, before attempting teeth whitening and user reviews steered me to this product. While it is the only one I have tried, I was impressed to notice visible result. I did experience slight sensitivity following its use, but it was not enough to discontinue its use and it quickly went away.

I also verified with my dentist before use and was assured that it will not damage my enamel. All in all, I'm pleasantly surprised with the results, but I do kept it up with lifestyle habits such as avoiding red wine and drinking coffee with a straw.

I would definitely recommend this product and have repurchased for myself.

You had to leave it on for an hour which is long but other than that I liked the product and would buy it in the future. My teeth got slightly whiter and was great

J'ai utilisé le crest 3d et en peu de temps j'ai pu remarquer que mes dents ont blanchies rapidement.je recommande donc ce produit. Je vais l'utiliser à l'avenir.

After i got my braces off i needed something to brighten my smile. after using these strips for 2 weeks my teeth lightened about 6 shades. that was over 4 years ago and they are still as white. i cannot believe the results and plan on repurchasing soon

I LOVE these white strips. I was unsure if I should spend the $70 for these.... but I am glad that I did. It came with 20 strips. I didn't even use all of them because I was happy with how white they were. I still have 3 left!

Crest professional white strips works just as well as professional teeth whitening at removing stains from your teeth. I always get comments on how white my teeth are and it thanks to this teeth whitening treatment

I found this product worked well but did not have a lasting effect. If you have sensitive teeth I would not recommend this product as does not cater well to sensitive pearly whites.
