I had very yellow stained teeth, now that I used this product it did not leave them pearly white like I wanted, but my friends have noticed that they are whiter. I will buy a new box in hope that it will get them the kind of white I want them to be!

So many of my friends had great results using the strips, I had to try them. After using them 16 days in a row, I am disappointed. My teeth have only improved about one shade. I expected better results.

I bought this product at a local Festival store about 2 months ago. When attemnpted to use the strips the backing would not come off the as I pulled the actual treated strip. The backing and strip were then impossible to seperate.

I had put off my dental work and had family issues come up that made me totally forget to bleach to prepare for it. I bought these 5 days before and used them and can't believe how well they worked! And no sensitivity at all!

I followed the directions and after 20 days I say very little change in the color of my teeth. With only 2 days left in the treatment my friend asked when I'm going to start my teeth whiting. I feel like this was a waste of my time and money.

I bought this one almost a month ago and have used 22 treatments. My teeth color still stay the same, no sign of brighter smile. I will try the remaining treatments and update.

May I know why there’s an uneven whitening after my first use of 3D professional effects white stripes? Should I continue or stop using the remaining white stripes? Hope to get your reply soon.

I drink lots of coffee and smoke. My teeth were getting yellow so I tried the 3d whiting stripes and they really worked!! I think everyone should try them. Thank you!!!!

I love these! A dentist told my mother I would never have 'white' teeth. But thanks to Crest Professional Effects I do have wonderful white teeth! I get compliments all the time on my white teeth and beautiful smile! Thank you !!!

These work just as well as a professional whitening... Easy and worth the work! Only negative thing I have to say about them is that my teeth have gotten more sensitive.
