So I bought this because I was desperate for whiter teeth, although I don't drink coffee at all, I had yellowing to my teeth. Sadly, after using this five times, not only do I have teeth sensitivity (which is fine because I expected it), I also have spots on my teeth that appear to be whiter. It doesn't seem to be overall whitening my teeth as much as it's just whitening certain spots more than others.

Needless to say with no fanfare. Crest 3D White Whitestrips Professsional Effects are by far the most effective most whitening whitestrips on the market. They are easy to use, affordable and after you get through using them the compliments just keep coming in. People notice a difference right away. They will improve your self esteem and you will find that smile of yours again!

I love this product! My teeth have gotten so white compared to when I first started using this product. It has surpassed my expectations. I have not used any other brand so i cannot compare. But i have been so happy with this product that I have not even thought about trying another one.

I have been using these white strips for many years. I just love how they make my teeth whiter and brighter. I get so many compliments on my teeth, even my dentist exclaims how white they are and ask what I use. They even laugh when they have to move the light above me because they are so bright. I would, and have recommended these white strips to my family and friends. I use the professional effects.

These whitening strips were my first I've ever used, and are still going strong many months later. I have bought another set just to keep up. These aren't going to give you a bleaching white smile, but will get some nice shades of white that are noticeable and look good on a smile.

I bought a pack of this last year and used it once a week for 4 weeks and people starting noticing my whiter brighter smile! I stopped using it for awhile because I didn't want to over whiten my teeth. People love comparing their teeth to mine. I now use one once every 3 months.

[This review was collected as part of a promotion.] These whitening strips are easy to use and effective. I see a huge difference in the color of my teeth just after one application. However, I don’t like how sensitive my teeth feel after use for at least a good 24 hours.

LOVE these whitening strips. I didn't think an at-home system would work - these make a huge difference. Have used several times before and will use again. Sometimes teeth/gums do feel oversensitive and need to break for a day or two before resuming.

[This review was collected as part of a promotion.] I love crest whitening strips I think these work amazing. Honestly I believe they work better than stated on the packaging and they only cause me sensitivity if I use them too frequently. I love that they don’t slide like they used to!
