These white strips really make a difference on your teeth! They can cause some sensitivity for the first few days but are well worth it for the results. You can actually see the difference after only a few days !

These are great if you are willing to consistently use them. I have sensitive teeth and these did not irritate them at all. It took about 4 days from me to really notice a difference but if you are consistent it's worth it!

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!

Leaves gums really dry if it touches them, and mouth chalky but does the job whitening wise for sure, doesnt stay white that long though, a d doing strips to often isnt good for your gums

Love these strips, they really work but you have to use all the treatment. I need to use something for sensitivity as it can hurt so much sensible teeth.

If your teeth are already pretty clean and free of stains you likely will not be seeing much difference as this is mainly to get rid of surface stains

Since using these products, my teeth have definitely seen improvement. I have sensitive teeth but these really don't bother them and produce noticeable differences!

I put these on two years ago when I got my braces off and have not needed to put them on since. My teeth are so so so white and they got rid of all the yellow. Love this product so so so much.

I really like this product. I have purchased whitestrips before a couple years again and they always slipped off. It seems like Crest fixed this issue. They whited my teeth very nicely.

Good product, but I just can't bring myself to use them as often as suggested. I may use them 2-3days in a row every few months or so as a whitening boost.
