I dont think this product works as well as others on the market. The strips come off really easy and slide around in your mouth. 

This product really helped whiten my teeth more!! It is very effective and I recommend it if you plan on whitening your teeth!!!

Love this product! Gets the job done, but it made my teeth really sensitive so I had to stop using it!

This product definitely works, but my teeth are so sensitive that I was in pain for a couple days after using.

These are good for popping in when you are watching a show. I dont know if they are as effective as these new systems with whitening lights

Left my teeth feeling sensitive. Which I believe is true of all white strips. I did see a difference in minor caffeine staining.

These strips really did help whiten my teeth and kept them white. It’s a much more affordable and easier way for whiter teeth.

These strips are awesome, they definitely show a difference after use, only con I have is they do make your teeth feel sensitive afterwards.

I’ve been known to spend hundreds on teeth whitening and this is the most reasonably priced product that I can count on when.

I am a social cigarette smoker and wine drinker most of the time and crest strip has remained my teeth fabulous white
