[This review was collected as part of a promotion.] I have been using the Crest 3DWhite Professional Ultra White toothpaste for about a week now and have already noticed a difference in the brightness of my teeth. The 4% hydrogen peroxide formula is the highest of any toothpaste and leads to the effective whitening while the extra strength fluoride offers the cavity protection I am looking for. I also enjoyed the texture and consistency of the paste with a tube that allows you to squeeze out the precise amount you desire. One thing I noticed is that the flavor of the toothpaste is a bit strong when compared to other products I have used in the past but it did not bother me at all. I actually found that it left my breath extremely fresh for quite sometime after brushing. I would highly recommend this product, especially to anyone looking for a toothpaste with maximum whitening benefits.

A lot of products advertise results right away and that is sometimes misleading. However, I did get significant results with this product after several weeks, using it twice a day. My teeth are much whiter and they also seem to glow a bit, which is great! Just don't expect results right away. Like most things, it takes time and consistency to see results.

[This review was collected as part of a promotion.] If your teeth are starting to yellow a bit then this is the product for you! After just a few days I can already tell a difference!! It tastes great and foams nicely to get in between your teeth too. Usually with products like this I experience sensitivity immediately but so far so good! I will continue to use and will recommend to all my friends and family!!

I love smiling so keeping my teeth as white as possible is a must. this system altogether is just amazing! I usually would see the dentist every 6 months just for a cleaning and now I go just for a check up cause my teeth are just a pretty shade of white !

Eh, like with most other whitening toothpastes, this one is no different. It does its job as a toothpaste but has minimal effect on whitening the teeth because the duration of contact with the whitening agents is not long enough in a regular brushing routine.

The only toothpaste I will use! The whitening agent is effective and I love that they offer the guaranteed whitening or your money back. I combo this with the whitening mouth wash and between the two, your teeth are pearly white and breath is left fresh as ever. I have never had a cavity so I swear by it!

I have been using this toothpaste for years! I have tried to try different ones but always come back to this one. It leaves my mouth feeling fresh and clean and my teeth are white! I use the 3D whitening strips a few times a month and the combination of the two works well for me!

I remember my first time using it like 5 years ago and it was amazing! I got more white teeth than ever had before. So later so many times I’m buying it I never get same effect anymore. But still I tried organic and blabla, this one I’d prefer for now. Probably it can’t help coffee addict people

I have been using this toothpaste for years. I really like it because it leaves my mouth feeling really refreshed and clean. I don’t know that it has done too much to whiten my teeth overall but I still love to use it because I feel like it cleans better than other toothpaste.

I love this toothpaste. The mint taste is good, the whitener helps between using the white strips, or helps to boost the use of them. My only complaint is the lid. It’s hard to keep it clean because the toothpaste is so thick and gets gummy at the opening.
