my teeth are literally so white! i was surprised how quickly they whitened too! I love my newly whitened teeth and i'm more confident and so much happier than i have been in such a long time! 100% recommend

I personally love these. they help me get my teeth whitened so fast. and it lasts, it's not too expensive but it can be. i personally would definitely recommend trying this out.

I quit smoking and decided why not. After years of minimal brushing and stains, within two days my teeth were significantly whiter. Make sure your dentist says its safe to use before starting!

I honestly do not feel like these give the least bit of a whitening effect. They are high priced and after using them continuously I did not have the outcome I had hoped for. I will be going to a professional next time.

I used both the professional express whitening treatments and the 1 hour express whitening treatments . The second one worked very well for me and I started seeing the results right away. But with the first one I didn't see a big difference

I love whitening strips but they can get expensive and sometimes leave stains on my teeth. I like how the end result is but it's never as white as I want it to be and definitely doesn't last so you have to keep doing it

I love the results of this crest 3D whiting. This product whitens more then other products. I don't have any problems using it. I buy and use this product once every two weeks, I'm very satisfied with results.

I used these before my wedding! It brightened up my smile so much. It did not make my teeth sensitive at all! It was such a help in the making myself looking perfect process! I really loved how it worked.

I love these white strips. I rarely use them but my teeth are incredibly white. I use to use them more often but now there is less of a need to. I feel so amazing when my teeth are nice and white and these do the job.

My husband and I keep a box of these around the house at all times. We'll whiten our teeth every once in a while as it does increase sensitivity, which is pretty unavoidable with a product like this. They work great, though.
