This work really well. I got a whitening set from the dentist an saw zero results which was disappointing because it was expensive. This however shows results. I have super sensitive teeth, and these caused no form of discomfort

i use these about every month or so, to avoid heavy damage on my teeth enamel. i don't really pay attention too much, but after using these i don't really see a difference. i feel like professional whitening is the only way to make a difference

I have been using these for about 4 years and they are amazing! SO many people ask about my teeth, and I always tell them this is what did it! P.S. I have never written a review before, that is how much I love these.

This product is the best whiting product I have ever used!! I will never use any other brand of strips to whiten my teeth because they always clean my teeth the best!! Don't want to use anything else!!

I really love crest white strips over any other brand. They're@much more comfortable and I can see results fast. I like to follow up with their whitening toothpaste to keep up.

These strips work well whitening my teeth but I do feel some tingling near the gum line towards the end of the directed period to leave them on. Once applied the strips aren't too bothersome but they can be a bit bulky and awkward to apply.

Been using this product for 5 years now. Only use it once a year because if teeth sensitivity. Does excellent job and makes my teeth super white. Leaves my teeth sensitive for a few days but the results are worth it

These are the only teeth whitening strips I use! They are definitely effective at whitening, just after a few days of using them. I always get them before events and it always does the trick for me! Definitely would buy again x100

This definitely works! I used it every other day consistently and it whitened my teeth for sure! The only thing is that it did make my teeth feel pretty sensitive, so I did use some sensodyne toothpaste and it did help!

Weren't as effective as I'd hoped and really irritated my mouth. It burned as it sat on my gums and lips and it's so hard to keep them in when I keep drooling! IMHO, not worth the time or money.
