tried once not a huge difference but my uncle has used this lots of times and has worked like a gem !!! his teeth are white

It does cause your teeth to be a tad sensitive but it's worth it. If you want a Hollywood worth sparkling smile then you need the strips.

These absolutely work for whitening but the sensitivity that follows can be a real problem! I think there are healthier options!

Whenever I use these I can't stop smiling because my teeth are so white! Kind of expensive but I think it's worth it

Super easy to use! I can still go about my day while using them. Noticed a difference after the first two uses

Crest whiting strips are good and you will get results, I just personally prefer to do in office whitening.

Great product, quality ingredients and worth the price tag. Highly recommend to anyone who has not tried this yet. You wont be disappointed!

I LOVE THESE! (In moderation of course ) but they work instantly almost and leave your teeth feeling so good!

These always work for me quickly and consistently without the mess a lot of other whitening kits always cause, they're great

Love. If you have sensitive teeth or gums I don't recommend. But they do a fantastic job and whitening my teeth.
