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.

I can’t believe how well these worked! My teeth passed the “tissue test” for sure. The only downside was my teeth are sensitive and became even more so while using these. I had to switch to a sensitive toothpaste, but I was so happy with the results. I used it two years ago, and my teeth are still whiter than they used to be. I think I’ll only use it as maintenance once every few years.

I’ve used various versions of Crest Whitestrips over the years and I’m quite happy with their newest products. I’m giving 4 stars because I do experience sensitivity with their products, but they are effective and I can deal with that as I typically use them 2-3 times yearly to keep up my white smile.

I'm 67 years old and used this whitening product because of an article I read in AARP's magazine that suggested ways to be appealing to your grandchildren. One of the suggestions was that you whiten your teeth. I'd been thinking about it previously so this article was the impetus I needed to buy the product. The effect is great! I plan on doing the strips every year from now on!

It’s effective in whitening your teeth for sure! But I hate the fact that it made my teeth feel extremely sensitive, and I couldn’t eat anything cold or hot without it irritating my teeth. The sensitivity lasts for a few days but it eventually goes away. However, if you are looking for a “at home” whitening solution and don’t have sensitive teeth, then try it out

For the price these whitening strips are very good and after trying them for a few days the difference in the color of my teeth was definitely noticeable. I have worn the strips for an hour at a time and gone about my daily business. When it comes to taking the strips of its a bit difficult to do so and this part is where i got to taste the whitening ingredients which was not very pleasant. If you could make it easier to remove the strips after the treatment it would be brilliant.

I am a fanatic about my teeth, and this product does exactly what I want! I have a whiter/brighter smile! I use the crest 3D professional white strips (whole box) twice a year! Some sensitivity at first, but doesn't last. I think everyone should give this product a try, it is well worth it and the money!

I loved these, i have sensitive teeth and it did not hurt like a different brand did. I got so many compliments from people because it made a noticeable change in my smile. I am a heavy soda drinker and I didn’t have to change my habits and the strips still worked

The best way to whiten your teeth! I get comments all the time for my white teeth and my dentist actually told me that I have a "movie star smile." You don't have to use them all the time to get results either. I used them every few days at first but now I only use them every few months. Highly recommended!

Good for special events or pictures when you need to brighten your teeth in a pinch. You can definitely notice the brightening by a few shades, however I find the effects do not last very long and they are a bit pricy for a box of strips. I would imagine these are also damaging to the enamel; however, they get the job done for when you need them!
