I've been using this on and off for a while now. Why? Cause each time I use it I don't really feel like it's making that big of a difference. Perhaps it's because I see myself every day, but I'm not sure. I see an impact, but I don't know how much. Still, no discomfort which is a very posi thing.

This toothpaste is absolutely everything. I am a clean mouth freak and brush my teeth three or four times a day. This toothpaste not only whitens my teeth, but it also leaves my mouth feeling fresh and clean. I HIGHLY recommend this product to others.

This is my favorite toothpaste by far! It's in between a gel and a cream toothpaste. It's almost a little bit gritty. I know that doesn't sound great but i promise it is. it really cleans deep and makes your mouth feel like you just came from a dentist!

This is my favorite toothpaste. It has a very refreshing minty flavor that is just strong enough to make my mouth fresh without being painfully minty. It was keeps my teeth from yellowing. I can't say it has made my teeth whiter, but has definitely prevented them from becoming any yellower!

I ONLY use this toothpaste! Not only is the minty fresh smell after everlasting, but my teeth have definitely become whiter compared to other toothpastes, charcoal powders, and whitening kits! The price is perfect and it's definitely the best toothpaste around. 

Nothing great here.  I use whiteners because those that make these products don't have what we need to make teeth white.  I like white teeth and brushing and scrubbing every morning shouldn't be the only way to get that.  So, I whiten and tben gently brush.  Done.

I love this toothpaste! It tastes amazing and it really does whiten your teeth! I use it every morning and night and after just 4 days my teeth were visibly whiter. Also, I didn't get nerve pain as I have had in the past with other teeth whitening products.

Love this toothpaste. It leaves my mouth feeling clean and I can tell a difference in the whiteness of my smile when I run out of this and use a backup product. This toothpaste hasn't given me any issues with tooth sensitivity, which several other leading whitening toothpastes tend to do to my teeth.

Crest toothpaste is my favorite toothpaste that I will only use! I like the Crest 3D White Whitening toothpaste Radiant mint flavor because the flavor isn't very strong or weak it's just right for me, I have used other Whitening toothpaste products but Crest 3D White Whitening is what works best for me! I like my teeth looking bright white! I have a pet peeve about teeth....I always receive compliments about how pretty my smile and teeth are....so for me especially what I look for in a guy he has to have those nice straight white pearly teeth!! All crest products perform very well for me and my family!!

I saw a significant difference in my teeth discoloration after using this toothpaste for a couple months. I had yellow spots on my teeth from where my braces had been and those have been lightened significantly. This isn't a perfect solution; it didn't get rid of the discoloration completely. You'll have to use crest white strips if you want something completely effective.
