I have used these many times in my life. But this 2020 year, I skipped taking care of myself. I took a picture 2 weeks ago and now (2 weeks use). See for yourself, the difference is visible

These strips are Awesome!!! They amazed me by taking atleast 14 yrs of very bad stains off my front teeth. I love my new beautiful smile Thank you crest :)

This Crest Brilliance toothpaste works like magic! If you brush your teeth with it after every meal like the bottle suggests, you will have white teeth! It really works!

I used this product as instructed and it made my teeth so much whiter! I noticed an incredible whiter shade of my teeth! And I was getting compliments from everyone on how white and beatiful my teeth were! Definitly my all time favorite product!!

I bought this whitestrips, it is cool. This is one of the most effective whitestrips for teeth whitening. Crest is the best brand if you want to get white smile. And if you want that everybody ask...ohhh..you have so white smile.

I've used these and also recommended them to my patients. You will see significant results within 1-3 times of using them. I now only have to use them every once in a while, usually for special occasions. =)

I purchased the crest 3D whitestrips reluctantly, taking a chance,but the results blew me away I saw a difference in about a week or so. I continue to buy this product being a great investment!

I have been using Crest 3 D whitestrips for less than a month. By my 4th treatment my yellow teeth were WHITE! I smile all the time now. I haven't smiled with my teeth showing for over 20 years!

This professional effects 3D Whitestrips rated the best in reviews so I decided to try it. After 2 treatments I already see results! Can't wait til all treatments are done!

[This review was collected as part of a promotion.] These strips are the best I have ever tried. Teeth were 20% whiter after one use and. Will use them a lot more. They did not cause teeth sensitivity afterwards, and they were comfortable to wear.
