[This review was collected as part of a promotion.] I was surprised on the results after only being able to test this toothpaste for 3 days. My teeth are normally yellow, no matter how often I brush them, because of a rare genetic dental disease. But, I did notice a difference after the first use. They seemed whiter and felt cleaner. It recommends that you use the toothpaste for 6 weeks for full results and I plan to do so. The only thing I did not like about the toothpaste was the overwhelming strong flavor. It's is a strong peppermint flavor that stays with your mouth. It may benefit people on diets. I wasn't able to eat or drink anything for about 3 hours after brush!

My daughter bought this product and I was so impressed on how white her smile became. I bought this product for my husband and I. I’ve tried other products but the active ingredients in this product does the trick. Our smiles are brighter and has removed the coffee stains on our teeth. I feel this is a great value for your money and worth the investment.

[This review was collected as part of a promotion.] I liked this product. Very minty, and I love a toothpaste with whitening. I like the consistency, however, I like a little more paste than this was. To me it was somewhere in between a paste and gel. I love the Colgate brand, and have used it for years and years. I will definitely continue to buy, but I think I like what I use better. Great product though...and whitening is always a bonus!

[This review was collected as part of a promotion.] This toothpaste was very interesting. It warms up quite a bit in my mouth with an electric toothbrush and I've never experienced another toothpaste that heats up like that. The scent kind of reminds me of Bengay but it isn't too bad. My mouth does feel clean afterwards. I used this in the mornings and my regular toothpaste in the evening for a couple weeks and am noticing my teeth are looking brighter. I like this whitening toothpaste better than Crest White Strips because the strips caused a vertical hairline crack that is in my two front teeth to become very visible in the light. It faded again over time but was kind of scary at first and looked horrible. The toothpaste is more mild and I will continue to use it occasionally to keep my teeth a little whiter.

[This review was collected as part of a promotion.] I brushed with the Colgate Advanced Optic white everyday. I noticed my teeth are whiter, they are normally sensitive and this tooth paste with no problems. It doesn't burn when I brush which is nice.

Die Colgate Optic White Advanced Zahncreme hat mich überzeugt! Dank der professionellen Whitening-Technologie entfernt sie sichtbar Verfärbungen und sorgt für ein strahlenderes Lächeln. Ich habe sie regelmäßig angewendet und erste Ergebnisse bereits nach einer Woche gesehen. Die Formel ist sanft zum Zahnschmelz und hinterlässt ein angenehmes Frischegefühl. Besonders positiv finde ich, dass die Zahncreme auch Karies vorbeugt. Für alle, die auf der Suche nach einer effektiven Whitening-Zahncreme sind, eine klare Empfehlung!

[This review was collected as part of a promotion.] I think this is the best whitening tooth paste i have ever used! It made my teeth so much whiter and with the quickness!! It didnt take months- it took like 2 weeks and didnt hurt my teeth or make them more sensitive- i have sensitive teeth so i cant generally use this kind of thing and it nit hurt real bad! I say go with this if your trying to whiten your teeth-quickly!

[This review was collected as part of a promotion.] I've been using this now for a couple of weeks. I have seen a noticeable difference in the color. I have been alternating between the Optic White and a sensitive toothpaste based on past experience with whitening treatments. I picked "bad taste" under cons; it's just a very strong mint flavor. I will purchase in the future when I need a brightening in color.

[This review was collected as part of a promotion.] I typically opt for and prefer a gel toothpaste because I find paste toothpastes are just that, pasty and gritty. I found this toothpaste to be very pleasant, smooth and had a nice strong flavor@ it wasn't peppermint or spearmint but more of a winter mint taste (I'm thinking like 5 gum). The toothpaste really lathered up and cleaned my teeth leaving my teeth feeling smooth and my breath fresh.

[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.
