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!

Super easy to use. You just peel off the strips and apply to your teeth . This product definitely works

Everything about these teeth whitening strips is great besides the price I wish they were a little bit cheaper but in all honesty they work amazing

Ive used a dozen kinds of whitenings trips n pastes & these Professional Effects from Crest are FAR & ABOVE all the others I've tried!

the only white strips i’ve ever used. super easy to use. i’ve heard people say these make their teeth sensitive but i’ve never had that problem!

Great! They work in a pinch! The stuff tastes weird and the feeling of the strips is kind of weird but its worth it!

Hands down this is my go to for whiting my teeth! I used this before my wedding to make sure I had that perfect white smile.

Works very quickly and efficiently. If you have a big event and need to whiten fast these are great!

I found these whitening strips to be very effective at removing stains and whitening teeth, however they did cause some temporary sensitive for me.

I tried these white strips at firts they did there work but after a couple of weeks i couldn’t tell the diffrence
