I CANNOT SAY ENOUGH. These work and are my absolute favorite line. To see the best results you really have to be consistent in using them but they really do work. I 100% recommended this to people and have never felt any adverse effects. Crest 3D White Luxe Professional Effects Whitestrips Teeth Whitening Kit

I used this product after noticing my teeth were stained from smoking and drinking dark sodas. It really works great after only about using three strips I noticed a huge difference of about three shades. After i was done with the entire treatment I would say i've went 5-7 shades whiter! I use these every month once a month to keep up the whiteness and its great everyone notices how white my teeth are now :)..... I would recommend these to everyone!! XOXO

Growing up, my parents (bless them) didn’t exactly stay on top of my dental care. My teeth were yellow and I had over a dozen cavities when I finally decided to be an adult and face my fears. I asked my dentist about teeth whitening and he told me not to bother with professional whitening, and to just get these. Can I just say, I love my dentist? These are a game changer. I can now smile openly without insecurity!

I purchased this box two times back to back and haven't had to purchase another since because that is how long my teeth have stayed white. It is absolutely true that you see results in three days and even more true when they tell you it is long-lasting! I love this product and will return if my teeth ever even need it again.

I love this whitening strips they really help my teeth bring out their natural white pearly color they’re a little bit pricey but I totally recommend them the value is higher than you could imagine I would recommend this to anyone who needed white teeth

The crest 3 d whitening strips worked well for me! I’ve only bought this product once or twice due to the price! The product was easy to use and made my teeth white In minutes! I would recommend this and I will be buying 3 d whitening strips again in the future.

i have natural yellow teeth (which suck), but after using this product for the allotted amount of time really helped whiten them! i highly, highly recommend these strips for people who can not afford to get teeth whitened professionally or just have troubles. it's very good and lasts long!

Yes these work ! I was wowed I’ve been using them for a few years now and I rarely do it anymore but my teeth are pearly white , it will probably sensitive on your teeth at first but it’s well worth it trust me look at my Snow White teeth . Thank you Crest

I have been ordering the Crest 3D Luxe Professional Effects for a year or so and recently I went to reorder and the package was different. When I put the strips on, they were thicker and didn't stick as well. The box is blue now not purple and it no longer says luxe.

[This review was collected as part of a promotion.] Starting off strong with a simple yet attractive package that is easy to open! The strips are super easy to remove from packaging and apply to your teeth. Directions are simple and the results are amazing. You wear these for 45 minutes at a time and after just the first use, I definitely noticed improvement in whitening on my teeth! happy to say that I haven’t noticed any tooth sensitivity so far after 3 uses now! The strips stay stuck to your teeth during the full 45 minutes, which is awesome because there has been other ones that stay very slippery and tend to slide off
