Good product, but gives you teeth sensitivity.

The directions said to use the one set of strips daily for 14 days. By around the 7th day, my gums had a chemical burn and I had to stop using them. I don't typically have sensitive gums but I guess this stuff is strong.

Excellent product

I had been wanting to try the strips but was afraid it wouldn't take 60 years of stains off my teeth but they did!! I noticed a difference after the first use but there was a really big difference after using for the first week. Now I can smile and not feel so self conscious. Great Product!! Highly recommend!!

Do you want whiter teeth without any of the sensitivity of other whitening strips? If your answer is yes, you must try the Crest 3D Whitestrips Dental Whitening Kit Professional Effects Advanced. I've been using Crest 3D Whitestrips once or twice a year for the last 6 years and I've been very happy with the way they feel on my teeth. I don't have any sensitivity using these strips, whereas some other brands I have. I typically don't have any stains anymore as these strips have done a great job of removing them over the years. These strips have produced the best whitening of my teeth I've ever had!

I'm a school bus driver, and it's very easy for me to put these on.After I drop off my first school because I have ten minutes in between and i put them on before I go get my second school. And by the time I'm done, it's been long enough for me to take them off when I park my bus. So far, i'm happy with the results, and i'm not even done with the process yet.In my teeth already look great

I have been using these strips for some applications and if I don't touch they whiten my teeth quite well. They are easy to apply and adhere well, they don't move much when talking. In my case I have sensitive teeth, so I reduced the time of use and frequency, and I still saw progressive results, without so much pain. The taste is tolerable and not uncomfortable.

These did not work. Some of them would bubble and some did not. Even those that bubbled did not make yellow staining even a little whiter. I have used Crest Whitestrips in the past from drug stores and big box stores and they worked nicely. It makes me wonder if manufacturer's and warehouse club's negotiations for lower prices result in lower quality products too. This is not the first time I have received a lower quality product from a warehouse club than when I bought it directly from the manufacturer.

Doesn't really work to whiten
