These strips work fast without the sensitivity. Its hard not to just keep putting them on everyday ! lol

i use these packs about twice a year and they always give me great results without leaving my teeth feeling super sensitive afterwards, recommend

Sometimes they make my gums sensitive but I do feel like they make a small change but nothing major.

I love these. I think they work great, and would never waste my time/money getting professional whitening since these work so good.

Comfortable to wear, much more so than the original ones. Does help get teeth whiter but not as much as I would like

They work !!! If you want some white looking teeth this is what you need to reach for . I just wish the white stayed longer !

Okay product. Gets teeth white, but makes my teeth very very sensitive. I wish I could get the white smile without the painful teeth.

The only ones that work in my opinion. crest has the best products for dental hygiene! I love these they really help with the staining on my teeth

Just like their toothpaste their whitening strips are amazing! I love these so much! They are the only thing that works!

It whitened my teeth, but sometimes my gums didn't feel great afterwards and I could feel it all over.
