[This review was collected as part of a promotion.] Colgate has been my go to brand, and colgate optic white advanced stain prevention has just reinforced that. I drink a lot of coffee and tea so my teeth become pretty stained. There was a visible difference in the shade after using this tooth paste.

[This review was collected as part of a promotion.] I used this product daily in the morning and at night. It left my mouth feeling fresh and clean. It also helped brighten and keep everyday stains off my teeth. It does a very powerful taste which I love but it did cause some sensitivity to my tongue.

[This review was collected as part of a promotion.] The Colgate Optic White Advanced toothpaste left my teeth feeling clean and whiter. The foaming action of the hydrogen peroxide leaves a refreshing feeling in your mouth. I was pleased that it did not cause tooth sensitivity as some whitening products can.

[This review was collected as part of a promotion.] I was a little skeptical at first. But after a few days, I could physically notice a difference in the whitening of my teeth. I'm a BIG coffee and tea drinker and with this toothpaste,I no longer have to worry about the stains! Definitely recommend!!!

Throughout my life I have only used Colgate products I am sad to say that is no longer the case. I have been using optic white since it first came out and I love it but not only was the price increased by $2 for the box of 2, the size was decreased from 4 oz to 3.2 oz and the packaging looks significantly cheaper. This is not the first time the size was decreased but I liked it so much I chose to keep using it. This is the final straw and it is sad but after being a Colgate user for over 49 yrs. I will now be switching to Crest. Shame on you Colgate.

[This review was collected as part of a promotion.] I was very pleasantly surprised with this toothpaste! I am an individual that doesn't normally care what toothpaste she uses. Though (since I love my coffee) I typically purchase something that says it has whitening properties. I didn't realize what a good whitening toothpaste was until getting half way through this tube. It really makes a difference!

[This review was collected as part of a promotion.] I really enjoyed this toothpaste. My mouth felt very fresh with the flavor and they feel extra clean. It's hard to say after a week if my teeth are much whiter, but overall I like the taste and clean sensation it gave me.

[This review was collected as part of a promotion.] This toothpaste is pretty good. Taste isn't too bad, but it's hard to see any changes in only one week. Hopefully the longer I use it the better the results will be. I would recommend this product to family and friends.

[This review was collected as part of a promotion.] Hydrogen Peroxide is good for cleaning your teeth, so I liked that this toothpaste had it in the this formula. The taste is also better than most whitening toothpastes which I really liked. Didn't see any difference in whitening yet, but will keep using.

[This review was collected as part of a promotion.] At first I was not expecting a toothpaste to make my teeth noticeably different. After day 2 of using Colgate optic white I could see the difference and this is from someone who drinks a lot of soda and eats processed food and some of this snacks I love definitely stain my teeth. The other plus is the way it makes my mouth feel so I clean and fresh. I have found my new toothpaste hands down.
