My teeth look 20 years younger!
Wow, this is the first toothpaste that has actually worked in whitening my teeth. For reference, they were mildly yellow, I'm a daily coffee with creamer drinker. I feel like this toothpaste has taken the color of my teeth back to how they were in my 20s. I like the fresh taste and smooth texture. The tube is smaller than regular toothpaste, but I believe in quality over quantity. I'd rather pay a little more for a quality product with better end results!

You need to read this....A+ stuff!
Ok, I have to give my honest opinion here.... I had (yes past tense) two teeth that had small stains on them and the last time I had my teeth cleaned at my Dentists office he stated he could not remove the stains... So, I read the reviews on this toothpaste, did some more research on Google and got it today. After lunch, I brushed my teeth and looked and the stains and they seemed to look lighter. I thought hummm.? Really? Then after dinner, I brushed my teeth again and just looked into the mirror out of curiosity (been a few hours) and I don't see either stain at all ... completely GONE! I am being very honest and so surprised that both stains were gone... Yeah, I know what you're thinking when you are reading this...B.S. right? Well, I am so surprised myself that I ordered two more tubes since they're on sale and I plan on giving one of them to a friend that has some coffee stains on her teeth and see if it works for her too... So, I would have to say that by purchasing the two tubes that I did, was way cheaper than going to my Dentist that stated they couldn't get rid of the stains. I'm totally 100% impressed with this Crest 3D White .. my new go toooooo forever! P.S. I am a ice tea drinker by heart and sometimes coffee too. Signed: So impressed by this stuff and it actually taste good and made my mouth feel fresh and my breath was fresh for a long time too....A+++++ toothpaste!
Quick Shipping as well.....

Beautiful white teeth
This works great. I always keep my teeth, nice and clean and bright and white and usually I have to buy Dental whitening, but this is the first time I found a product that you can just brush your teeth a few times a week and it keeps your teeth, nice and white.

Refreshing toothpaste that helps to deep clean your teeth.
Good tasting toothpaste that cleans my teeth well. It seems to have a tiny bit of grit to it to help remove stains on your teeth.
The tube is quite small. So, you do not get a lot of toothpaste. But a little goes a long way. I think that it did make my teeth a bit whiter. I did not have any sensitivity to it at all.

Works!
This is an updated review changed from 4 stars to 5 stars after using it for a week. This toothpaste actually removed Matcha Green Tea stains that were between my teeth and other tight areas my hygienist couldn't get into. I'd say this is a product for stubborn stains and I wouldn't use it more than maybe a week at a time because it's expensive for the small size you get and I'm not entirely sure what the long term effect is on the teeth.
