If you want white teeth buy these strips! My teeth started to get a yellow tint and I seen results in less than a week. Highly recommend

Was given this as a gift for Christmas and I love it. I accidentally fell asleep and they burned so don't fo that!

I love these been using it for year my teeth look so white ! Cons are your teeth will be sensitive for a few days but oh my goodness so worth it

I love these white strips and they work better then high end products out there! But they leave my teeth feeling super sensitive.

Hate that Crest tests on animals but these really work and people comment on my white teeth all the time. Up your game Crest- stop the cruelty!

Do not waste your money! The Crest 3D whitening strips do not work whatsoever. I've tried them twice but I wouldn't try it again.

I've noticed a good improvement with this product that works relatively quickly. I get lots of compliments about the noticeable difference

Super easy to use! I can still go about my day while using them. Noticed a difference after the first two uses

Wowwww. I was amazed at how much whiter my teeth looked after one week!!! Love these i recommend these a d im on my 3ed package.

THE BEST WHITENING STRIPS EVER ! i swear by these, they leave my teeth pearly white after every use
