This is extremely effective in whitening my teeth. I have been using the Crest White Strips for many years now and I am very satisfied in the end results. They do an excellent job of brightening and whitening my teeth and removing stains. I would say the one drawback is the sensitivity of my teeth afterwards and a couple of days following after using this.

I love these whitening strips! They work very good! I use them everyday! They are a bit pricey but In my opinion they are worth every penny! The pros are they leave your teeth so white and it last for a while. The only cons I have is that if you have sensitive teeth it can make them more sensitive the first couple of times using them.

This worked really well for hubby but I saw no big difference for myself. I suspect it's because my teeth weren't particularly stained just needed brightening. I wanted to be in a different range of white but that wasn't the case. I would recommend though, for people whose teeth are stained.

The BEST teeth whitening kit!! I saw results within 3 days of using, my teeth were instantly whiter! It’s a little bit on the expensive side, but very worth it considering the results. I purchase this product all the time! I would recommend this product to anyone!

I've been using these since high school (10 years) and they are incredible. They make my teeth noticeably whiter after just one use. I typically only use one strip every couple of weeks now for maintenance. The only downside is the sensitivity it causes but only lasts a day or two.

These white strips really work after just one use! I have used these for years and it instantly takes away any stains and keeps your teeth white for a couple months. With any whitening system I did experience light sensitivity but nothing major at all!

I had a coupon, I figured what the heck. I am sitting here with my teeth clenched together for the last 20 minutes now because almost as soon as I put the strips on, the slid back off. They do not stick well at all. Because i spent the money, I am going to try and complete the whole ten day regime. Given this poor initial performance, I honestly do not expect any worthwhile results.

I went for my cleaning this week and my dentist actually thought I had went to someone else to have whitening done. We had discussed it so many times but after reading horror stories on the internet I swayed back and forth. Then I had a chance to try Crest 3D Whitening Strips. I am so happy! It wasn't messy and the results were noticeable after the first use. They didn't burn my gums and whitened gradually so I had no teeth sensitivity that I experienced with other products I tried.

LOVE using these things , I would use them every once or TWICE a month one in the beginning of the month and one towards the end of the month and they make my teeth look professional. If you have sensitive teeth I recommend you using them once a month or you’ll get sharp pains on your teeth when eating cold foods. It can be a bit pricey but I highly recommend this product.

I will be 72 in Jan. '15 and have been using these strips for at least 10 years. I have all my own teeth, minus the 4 wisdom, and really maintain them with frequent professional cleanings. I have very white teeth from using the strips whereas many others much younger than I have the "yellow" look. They don't need to be done very often to keep their whiteness and I do drink coffee,tea,cola sodas but no wine.
