The go to when whitening my teeth. They always work well and whiten my teeth within just a few weeks.

I would totally get them again. They stay in place and they worked one of the better things I've tried

i have tried these but they haven't worked too well. i see a small difference but not as much as i want for my teeth!

Crest 3D whitening strips are the best teeth whitening product I've ever used by far. I honestly can't believe how good my teeth look now.

Works well but you have to use a lot of strips before noticing a big difference. If you leave it on too long, it definitely hurts after

Good results, as expected with whitening strips. Visible results within few days of application ( as instructed ).

Only takes a weeks worth of use to get my teeth looking sparkling white. The only product that doesn't leave too much goop on my teeth

This product really helped whiten my teeth more!! It is very effective and I recommend it if you plan on whitening your teeth!!!

I like these but they leave me feeling a little too sensitive sometimes! But they do what they should and I do think they help!

Works pretty well,I usually use the 30min one and it does helps makes my teeth look white. I use it every other week or before a night out
