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

Really think this product does work. Except you really need to use these things for a while to see a difference but I'm actually really liking how these are making my teeth look and would for sure buy again.

Really helps to whiten my teeth in a fairly quick time frame. Only negative is that sometimes I experience some tingling if I have the strip on my gums after wards, easily relieved by Tylenol and time.

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 !

I LOVE my crest whitening strips! I get compliments all the time on how white my teeth are! I've tried other products and nothing ever compares! I will always be a crest fan!

These are my go-to whitening strips. I only have to use them once and then I can go several weeks/months without using them again. I don't like how they make my teeth sensitive the next day or two after using them though.

The best way to whiten at home if you ask me. Fast, efficient and economical. It's the best of all worlds for someone wanting white teeth fast and without seeking a professional - would highly recommend to a friend

Best whitening strips I have ever used. They will make your teeth sensitive so I usually have to skip days in between but they make my teeth whitest white.

Extremely easy to use! I've used them for about 3 years now and I wouldn't change a thing! Once you apply them, they are so comfortable I wear them in the shower and doing my makeup! The results are great! Highly recommend!

It is amazing. I used this like a week before my wedding, and everybody asked how I did it!! Lol in my wedding pictures my teeth are really white. I'd highly recommend this to everyone who is in need of teeth whitening process.
