I got it on sale so i was pleased with that since its a tad pricer than i normally spend on toothpaste.
I got noticeable results within two weeks and i plan on continuing use.
My boyfriend was also pleased with this product.

I love this product within 2 weeks of use my teeth became so white

I noticed whiter teeth in a week and it tasted great

Not all that happy with this toothpaste. I found it less effective than many other whitening toothpastes I have used.

Still one of my favorite brand of toothpaste so far and the taste is good and fresh, It work well!

Great product! My dental hygienist recommended this product because spots were less visible on teeth after a couple of weeks. It works great!

This toothpaste has some great qualities. As a smoker I notice that my teeth can get stained very quickly, but after I first time used this toothpaste I noticed a difference in the color, at the end of the first 14 days, I did notice a real improvement in the color about one shade whiter. It really leaves your whole feeling fresh as well.

Not sure how it works, wasting $ at least to me

Clean, white, bright! Crest 3D White is my new favourite toothpaste! Never had my teeth feel and look so good!

Used it for a few weeks and saw no difference. I also found myself washing out my mouth multiple times to get rid of a lasting flavor.
