Worked absolute wonders! I loved it, I didn't have any problems with it. It didn't make my mouth feel so weird or unloved :) my entire family loves their products we use them all the time :))

I seriously only had to use the a couple times to see dramatic results! They work so good and haven't made my teeth sensitive. I use these around 1 or 2 every two weeks just to keep my teeth white and from staining from coffee and food.

Best whiting strips. Within one use you see results. It literally makes my teeth paper white. Only thing is they can make your teeth really sensitive so I wouldn't use them daily.

Love this product! Whitens teeth so fast I use them all the time and I swear by them, it is truly a great product. I will always continue to but them!

If you have sensitive teeth, pick a different whitening method. If not, this is a super easy and quick way to get your teeth sparkling white. It is a little expensive but you only need to do like 1-2 strips a month to get great results!

I love crest whitening strips. They are a little pricey but they really get the job done. I do not use them every day like the instructions say because you will get a little sensitivity but i highly recommend if you want white teeth

i've used the white strips since they have existed and my teeth are pearly white. i have such white teeth. i get so many compliments and everyone always asks me what i do. i really should sponsor crest lol

I love crest! I've been using this to keep my smile white and clean. I am an avid coffee drinker and I use crest to remove hard stains. It is very effective and a little goes a long way. Will recommend!

I have used this product for 2 weeks consistently. Every night I put a strip on and keep it in for about 20 minutes. I have noticed a difference in my teeth and they are whiter. I'm going to continue doing these strips for about another 2 weeks.

My teeth are a little too sensitive for these. Use them and my teeth hurt for a few days. I've used their Gentle Routine strips, and they work better for my teeth.
