In just a few days I saw amazing results! My teeth started getting whiter & I was surprised. I am definitely going to be purchasing more

I noticed whiter teeth after just one use. I am excited to have pearl white teeth again!! Highly recommend these!!

This definitely delivers when trying to get pearly whites! However, you must continue to use them regularly to keep your teeth white

These make my teeth shine! I wear these every once in a while when I need a pick me up and they really do the trick! 

Increased the whiteness of my teeth after one use would highly recommend to anyone who wants a brighter smile

These were great...until it made my teeth super sensitive and I couldn't stand having them on for even 10 minutes.

10/10 definitely recommend! I noticed a huge difference in the whiteness of my teeth after 1 use. Not even being dramatic

Love Crest strips but definitely leave my teeth so sore and so sensitive!! Could be different for others.

amazing. works so so good. also make your teeth very sensitive so be careful. literally makes your teeth so white you will be shook

The whitening strips did work however it did make my teeth become sensitive so I would use them every other day or every two.
