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

used these for prom back in 2016. they half worked they did make my teeth 2 shades whiter but not a big difference. I would try them again but they tend to more on the pricer side.

My teeth want white instantly after 2 weeks. I was not expecting any of this results at al buh it really surprised me. I had a bit of trouble putting it on but I got the hang of it and I would recommend and buy it again!

Who likes yellow teeth? These are another one of my favorites. I always have these in my purse. Just in case! I probably use these about once or twice a week. But they actually work!

these hurt my teeth terribly. the first time i used them it was fine, the second time and last time, they made my teeth so sensitive i could barely stand it.

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!

These whitestrips were wonderful. The best product that crest has to offer. However, I dont know if I would use them too often as they seemed very strong. Made my teeth pearly white and thats saying a lot as I drink coffee all day every day!

After only about 2 weeks, my teeth are as white as pearls! I get compliments often and inquiries of "HOW?" All I say is.... "Crest, 3D White Whitestrips Professional Effects."

Very good product I put one on every week and for 5 weeks it whiten my teeth and made my smile look better my friends said I look way better with my teeth I would buy

Best kit ever for teeth whitening! I had braces and had some stains. Used this kit every day and no more stains and my teeth have remained white ever since !
