They really work! My teeth were at least 3 shades lighter. Only thing I can recommend is taking it slow when using. They can increase tooth sensitivity! Overall, great at home whitening kit!

[This review was collected as part of a promotion.] I've been using this in order to whiten my teeth for an important event. It's really easy to follow the instructions and you have to make sure to be consistent in order for it to work.

Great for getting your teeth there whitest with minimal effort. My teeth are not too stained but these always take me back to paper white! Could be longer because they don’t cover all your teeth just the ones that show in the front.

I love to have a bright smile. These strips make it so easy to do at home. Lately I have struggled with sensitivity to my teeth. These do not worsen that feeling.

Great whitening strips. I love using them but have a weird flavor. I feel like my teeth have become whiter a lot sooner than other products that I’ve used. I would use this product again.

I love Crest 3D Whitestrips. I use them twice a year. I get many compliments from people asking me if I get my teeth professionally whitened! That's where I advertise for Crest!

I love how white Crest 3D Luxe professional white strips leave my teeth. Even after one session, they are whiter and brighter. The only negative is that my teeth are more sensitive after using this product.

These work if you need 1-2 shades lighter but it’s nothing drastic. If you’re just wanting a pick me up between dental trips, they work. I still recommend seeing a professional though.

These strips work fast! I saw nearly instant results. I’ll usually buy a pack of these before a big event or when I feel like I need a confidence boost. It does tingle a bit but the results are so good I don’t care.

I’ve used so many teeth whitening products- from drugstore to professional and I always end up coming back to these. I love that I can use them without having sensitive/painful teeth for days following. Would (have) recommend to anyone!
