Love the results these give me, they definitely make a huge difference. My only complaint is that they will leave the teeth feeling sensitive after, i would limit to using these only once a week.

These worked amazingly well. They didn't make my teeth a lot more sensitive which was sad because my teeth are already pretty sensitive. It also left a pretty gross film on my gums.

This strips work like magic, however, they do make my teeth a little more sensitive than usual. The product is a little pricey but for those welling to spend a little money I do recommend this product

The crest white 3-D stripes are really effective. Ive been looking for products to reduce the stain on my tooth an none worked. However these stripes removes 75% of my stain.

I used it for prom 2011 when I was a junior and it made my teeth really white. A lot of people notice. You don't need to spend a lot of money going to the dentist when you can just buy these

I like this product and use it when I need to. When you're consistent, you will see a whiter smile that others will notice BUT it is pretty pricey, especially if you want to consistently use the product at home.

These whitening strips work so well, you can notice in instant difference in the shade of your teeth just by using the whitening strips one time. It's pretty pricey for the amount in it but it works for really well.

My first time getting my teeth whitened was so painful, my gum line was chemically burned. With these whitestrips there is minor sensitivity but overall it's great even only at day 5/14!

these work great! i used an entire box and noticed a huge difference in my teeth! they look so much better and gave me amazing results. i used 3 per week. on the more expensive side but worth it. id buy it again!

I often suggested Crest whitening strips to my dental patients. I retired a few years ago but wanted these for a college aged granddaughter after noticing her boyfriend had whiter smile than she did! He admitted he's used Crest Strips!
