[This review was collected as part of a promotion.] I used this product for 1 week, brushing two times a day. I found that after brushing my breath was fresh and my teeth felt smoother than when using my previous toothpaste. I was hoping to see an immediate whitening result, but within the 1 week of use I have not seen a noticeable difference in the whitening of my teeth. I am hoping with prolonged use, two weeks or more, I will see a difference in the witness of my teeth. In all, I like this toothpaste!! It takes care of all my dental need such as cavity prevention, providing fluoride, Providing formula for whitening teeth and removing stains, and lastly it is safe or the enamel of my teeth. I especially like how my teeth feel smooth and grime free upon brushing....better than other toothpastes I have used in the past!

[This review was collected as part of a promotion.] This toothpaste gets my teeth really clean and my mouth refreshed. I have already noticed my teeth looking whiter and more sparkling in the two weeks I've been using this. At first the taste kind of got to me but it has grown on me. Do wish this was not so thin when you start getting around your mouth to brush, as it can be messy. Otherwise, it does seem to be doing a great job.

[This review was collected as part of a promotion.] My daughter has used this twice a day for a week. There is a slight difference. Over time I think her teeth will change a shade or two. I think this would be great for whitening maintenance after using whitening strips

[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.] This product definitely does its job of whitening teeth and preventing stains. Your teeth feel very clean after using this product. I wish it did have a better taste. Overall, I would recommend this whitening toothpaste.

[This review was collected as part of a promotion.] The Colgate Optic White Advanced toothpaste did a good job cleaning my teeth and freshening my breath. I used the toothpaste twice daily and it left my teeth looking noticeably whiter. I felt that the flavor of the toothpaste was too strong for me.

[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'm very happy with the Colgate® Optic White® Advanced Stain Prevention. The taste is minty and refreshing but not overpowering. It leaves my teeth feeling clean for a long time. It also has improved the overall color of my teeth, but it will probably take some time to notice it more. I recommend this toothpaste to everyone!

[This review was collected as part of a promotion.] I have never used a stain prevention tooth paste before, so this was new to me. and I received this item as a sample for an honest review. The flavor was a little off. Its minty but has something else that stands out. Im assuming its whatever prevents the staining thats strong. Its not bad that I wouldnt use he tooth paste, but it was what I noticed first. With that being said, I can feel this clean my teeth. Its stronger then regular tooth paste. I will continue to use this sample, and see if after 6 weeks it has done anything different to my teeth.

[This review was collected as part of a promotion.] This Colgate Optic White Advanced toothpaste is excellent. The texture is great, smooth and provides a sleek and clean finish. It's cool that it is vegan, and has a peroxide patent. The toothpaste definitely provided whitening and smile confidence and protection. Would highly recommend.
