Works very well, kind of expensive and sometimes hurts my teeth if they're sensitive but the effects are worth it, they leave your teeth very very white

I love using these! I had braces when I was in middle school and my teeth were not cute when I got them taken off. I bought some of these and I still use them today because they are such a good product.

i loveddd this product. i have retainers so id put my retainers on over them and keep them on all night. it is very expensive though so i dont use them a lot.

Love these! Super easy to use and not tacky after like a lot of the other brands. They stay on super well and results are instant! I take them with my everywhere I definitely recommend these to anyone who wants a brighter smile!

These whitening strips are the best I absolutely wont use anything else but these !Every time I use them I get so many compliments about how white my teeth are .These are just as good as the higher dollar ones for sure.

After trying these, I will never try anything else! You really only need one box and after that, you just have to maintain with good brushing and oral hygiene! I get compliments on my teeth all the time and it's 100% due to these strips.

These are my go-to whitening strips. I only have to use them once and then I can go several weeks/months without using them again. I don't like how they make my teeth sensitive the next day or two after using them though.

All I can say is wow!! The first day I noticed a change! It's like having it done at your dentist without the big price tag! I use it about four times a week the first week. I achieved my desired shade and now it's once a week and I drink coffee!

I'm glad I tried thses #Crest3D white strips. I noticed a change in the coloration of my teeth the first week after using these strips. So I'd be buying this product from now on.

It really works! If i felt sensitivity i just skipped one or two days and continued using it. I feel much better now that i can smile without being selfconscious of my teeth!
