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).

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

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

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

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.
