This product works really quickly to achieve the results you want for whiter teeth. I don't use it too often though because it causes sensitivity pretty badly

This product does really whiten teeth but I have really sensitive teeth and it made my teeth hurt so bad. I didn't even get through a few applications without having to throw it away because I was in too much pain.

I couldn't be more excited to say that the whitestrips have made my teeth and amazing vibrant white. I have always had off colored teeth which bothered me but now I have the smile i've always wanted.

I really love this product.Really easy to use.I really do recommend so aforementioned and easy to apply. It really does do the whiting job.10/10 remember

Easy to use but amazing effect. Don't even notice it's on your teeth. Really a good product. I have used this for the last five to six years and I wouldn't recommend any other type.

I am using CREST its very unambiguous product.I love it.its reduced yellowish color quickly not an week its done in few days.Thank you CREST Team members......TEETH+CREST=WHITENING TEETH+OTHERS(COSTLY)=YELLOw

Works great but not the best for sensitive teeth does start to hurt after a couple of uses would use again though it whitens well just have to be careful not to overuse them

I am a coffee and tea drinker and after several years, this has ruined the whiteness of my teeth. I think the effects of this product was well worth the price.

The only teeth whitening system I've used that works. I've done zoom before and it left my teeth splotchy and really sore, but crest isn't super damaging to my teeth but visibly whitens

sooo good. works so well. very easy to use and doesn't taste bad or too strong. jus don't leave them on for too long because of teeth sensitivity, but other than that sooo good!
