Fabulous product. If you follow the instructions as directed and also be discipline and follow all the guidelines you will see a dramatic difference. This product initially made my teeth white and bright.

Love these white strips! I use them every time I want to give my teeth a little extra love in color. It definitely works - I use it last thing at night and it's never given me any sensitivity issues!

I love these Crest Whitening Strips! This is the only brand of whitening strips I will use! I find they don't make my teeth too sensitive and they do a great job of whitening my teeth in that time! They're great!

They are good but my dentist said it's not good for the enamel or your teeth if you overdo it. So I limit it to once every 1-2 months. If you have sensitive teeth, your teeth will feel sore afterward.

i am a big fan off teeth whitening and these whitening strips actually work and help fight stains. i'm an avid coffee drinker so these are great in my opinion

I always get asked how I get my teeth to be so white. People can't believe it's done at home when I say it's crest 3D whitening strips. They're super easy to use and are completely fool proof.

I've use this product a couple times and I am definitely not impressed with it at all. The strips did not want to stay on and I never saw any results.

Love these crest white strips! I use them regularly when I have an event or something to go to and they don't make my teeth super sensitive like some teeth whitening products do.

After just one use my smile is soo white and bright. It doesn't slip while using which is very useful. It does though make my teeth a little sensitive.

The only whitening strips that have actually made a difference. I use it once a week however if you're teeth are sensitive you should do it less often because it will cause shocks of sensitive in your teeth.
