Absolutely love these whitening strips! They're perfect to just put on while you do your makeup and take off and they leave you with a pearly white smile! They do unfortunately make your teeth a bit sensitive but all whitening products do that. Highly recommend !!

These work really well BUT they're so expensive I can never use them for too long because I hate spending money on them!! It's frustrating because they really do work. Also they make my teeth extremely sensitive like if I leave them on for longer than 30 mins I'll be in hella pain!

The most cost effective and efficient product I've used to whiten my teeth without having to go to the dentist! I drink a lot of coffee and will use these with good results. People tend to notice and I always can tell in pictures! They make my teeth so white!

I bought these because so many people swear by them but unfortunately I didn't get the results I was hoping for. They made my teeth incredibly sensitive so I couldn't use them every day which may be the reason I didn't get good results, but they were disappointing on the whitening aspect. I will be looking to try a different product next time.

When I have an event coming up I can use Crest 3D White Professional Effects Whitestrips Teeth Whitening Strips Kit 40 Treatments Twin Pack once in a week and see a difference. These whiting strips don't leave my teeth feeling extra sensitive. I feel they are cleaning while protecting them. I would highly recommend them and they are worth their price.

Love this product for my pearly whites! Easy application process and the strips don't slip off like they used to. Pricey but a great alternative to heading to the Dentist and much cheaper. Would recommend for a super white, looks like you went for a dental appt. smile!

I love these. They have transformed my smile to noticeably whiter! People ask me all the time how my teeth are so white. All of the white strips work, but professional effects is the best. I have a lot more confidence due to this product. Thank you Crest! :)

I'm a dentist and usually recommend crest white strips to patients looking for an easy, cheaper, effective whitening treatment. It's safe to use and produces great results when used correctly. It can cause mild temporary sensitivity, but overall great product!

Finally!!!! A teeth whitening strip that doesn't make my teeth ache in pain. I love these strips, they give quick result and they are easy to use! My favorite thing about this is that I can whiten my teeth pain free + there is no icky after taste from the whitening strips. 100% these are one!

Crest 3D Whitestrips Professional Effects are the best thing you can do for your teeth if you want a whiter, brighter smile. They can change the look of your teeth almost overnight and they cost less than a professional treatment would cost. Besides that, you never have to leave the comfort of your home.
