Leaves gums really dry if it touches them, and mouth chalky but does the job whitening wise for sure, doesnt stay white that long though, a d doing strips to often isnt good for your gums

This is a nice product, definitely see a difference in the shade of your teeth. I just wish it wasnt so expensive!! If it wasnt I would add it to my regular teeth brushing regimen.

These have come such a long way! They used to slide off your teeth and be so annoying, but now they actually stay on! They’re the best for an event or just wanting to keep your teeth whiter!

crest white strips are my go to whitener,  how easy, just apply and you can continue whatever you are doing, the whitestrips stay applied better then other brands, 

I love the strip for a fast result I can put them on when I’m getting ready they really help with special events when I want my teeth extra white I love them they do what they claim.

This product works but is very expensive so I rarely purchase it. Also, like almost all whitening products it makes my teeth feel sensitive so I don't use it to often. It does work though and make my teeth appear whiter and brighter. Great results.

I have tried plenty of products from retainers where you insert the gel to professional grade teeth whitening treatments and I have by far received the best results from these! I notice a difference instantly and I love how affordable they are!

my favorite self care product. use these approximately once every 6 months and get constant compliments on my white smile! the best i’ve ever tried and more affordable. not as damaging as others and i would highly recommend these!

These keep my teeth white but also makes then sensitive. I will continue using however I usually apply one strip a week instead of daily. This way I can keep drinking my hot coffee every morning.

I used both the professional express whitening treatments and the 1 hour express whitening treatments . The second one worked very well for me and I started seeing the results right away. But with the first one I didn't see a big difference
