I want to love this product but unfortunately my teeth gets really sensitive to this. It's hard to eat or drink anything cold the next day. Even sucking cold air into my mouth is sensitive. I wish there were more options for people with sensitive teeth. 

Even thought it is very bad for your teeth this product is my guilty pleasure. I use it about once a week if I need it. But I bought it a couple of times and was never disappointed. I definitely recommend it works very well and whitens after 2 or 3 times. Crest 3D White Luxe Professional Effects Whitestrips Teeth Whitening Kit

Lets face it, we all want a perfect white smile but in wanting so work needs to go into it. I grew up with crooked teeth and they werent the whitest I wanted them to be so what happened I had braces for 6 years and after they were taken off I had to start phase two:whitening. I religiously brushed and rinse 3x a day only using 3D white products and added the professional whitening strips to my regimen. After a few days the results were mind blowing! I had that perfect white smile I had wanted, a 180 difference since I was 13.The packaging is different but the results are amazing!

[This review was collected as part of a promotion.] These crest white strips are so helpful when you need a quick teeth whitening! I’ve used these for a couple days now before bed and I already notice a difference! It’s gradual but definitely there! I’m hoping for even more after a few weeks of use! They are a little tricky to apply but I’m starting to get the hang of it. I found that making sure your teeth are somewhat dry helps them stick better. Eat at home whitening!

The only whitening strips that I've ever used that I notice a difference as soon as I take them off. My teeth are really sensitive and they definitely make mine hurt but beauty is pain baby (ps this is completely UNEDITED) yeah, they really that white lol colored contacts by qosmeticabeauty on insta!

Work to whiten teeth a couple of shades whiter if you consistently use and follow directions. Strips are designed to fit all so you tuck under/ over to fit your teeth, this can cause the strips to move around if you are not careful but once used to it they work great!

Whenever my fiancé and I need to whiten our teeth, we are both coffee drinkers. This is the only one that has been tried and true. It's a little pricey, but not bad if you do it twice a year. It gives you the results you need, in not a lot of sessions.

These were actually recommended to me by my dentist so I started using them I have had a couple of days where my teeth were sensitive but I don't know if that was completely from the white strips most of the time I can use them and they are OK and they do really good at whitening my teeth

These absolutely work! They whiten your teeth and if you use them consistently you can get blinding white teeth. The only downfall for me is that they can make my teeth a bit sensitive. I find myself buying these every once in a while to freshen up my teeth and remove stains.

So basically a bad depressive episode caused me to neglect my teeth and then endless amounts of coffee didn't help. After working myself out of it and finally taking care of myself, I still couldn't smile with my teeth. I was self-conscious. I thought about getting them professionally whitened but opted to try this. BOY. I saw results by the third day like the box said I would. By the fourth day, I could almost cry. I'm not done with my 20 treatments yet but this has seriously changed everything. It makes me so happy. I can't believe I could have just done this the whole time. Thank you crest, for this lovely product and giving me my smile back.
