it is working but not as fast as expected or promised. but I would buy it again

According to Crest, this whitens your teeth. It didn't for me.

I would brush everyday, twice a day with this toothpaste, and instead of whitening my teeth, (by the way I only bought this because it was on sale), it made them look yellowish, until of course I brushed them again, making them look whiter. This happened every time. I already know it's not my teeth, because when I used other toothpastes, they were the same shade throughout the day, not brush: white, leave: yellow, brush again: white again.+

Way to expensive for toothpaste that really doesn't make a difference in the shade of your teeth. I don't want to have to buy all the side stuff to make the product worth it, you can use baking soda and your teeth will look better.

Doesn't work great... But it tastes good

I had used this product three times a day, with flossing and mouth rinse.. I did not see a noticable difference in the colour of my teeth, let alone did they appear whiter. It tastes good..

I didnt find that this toothpaste was any better than other whitening toothpastes. Just average for me.

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

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.

I can't tell if this toothpaste works well for whitening but for sure I can say that this one is discusting!!! First it tastes bad, second It leaves the mouth with a strange sensation like if you had eat something pasty... I didn't had the impression to feel good in my mouth it was so awfull that I decided to brush my teeth again with my other tooth paste.

This tooth paste has a very strong taste that last but has tiny balls that get stuck in your gums. This toothpaste did nothing for minor stains on my teeth. Wouldn't recommend unless you are looking for a product that has a strong minty flavour.
