If you are in need of a professional cleaning. Save your money. Buy these. I used these years ago and have not needed a retouch since. Truly the best!

i've used them before and they definitely work but they would make my teeth hurt. so i haven't used them in a while,but if i had to use them again i would.

I am really happy with the results of the Crest White Strips. They were easy to apply and stayed on well. The light was comfortable. My teeth turned out so white!

The product works super well almost as well as professional whitening. It does need more consistent usage thought and the results aren't instant. 14 days of use makes them shine bright though!

This is seriously one of the best teeth whitening systems it always does the right thing and makes my teeth look super white at the end especially after a couple times I would really recommend this to anyone that wants to whiten your teeth for cheap

They do work! I don't like too white which looks kinda fake, this is just making my teeth at the color I like! Don't use it too long tough. You need to follow that direction.

Best whiting strips. Within one use you see results. It literally makes my teeth paper white. Only thing is they can make your teeth really sensitive so I wouldn't use them daily.

I love that if I want a quick fix for my coffee stains on my teeth I can just pick up the strip put it on for 10 to 20 minutes and automatically feel so much fresher

Seems to take a bit but these are very whitening! They work well and leave your breath smelling very fresh and minty! I would recommend these, but not for someone who wants there teeth white in one use for an event or something

This stuff really works and is comparable to the whitening at the dentist office however you must finish the whole set. Without doing all the strips it would not show results
