[This review was collected as part of a promotion.] I tried Colgate optic white for about a week. You can taste the peroxide in it and it stings a little as you brush. It doesn't leave a weird aftertaste though so that's good. After looking at my before and after picture, it does seem like it has whitened my teeth a little.

[This review was collected as part of a promotion.] I used it twice a day. I would prefer 4 - 6% peroxide for better whitening. Professional teeth whitening is very expensive. Consumers are looking for a toothpaste that can replace professional whitening, even if it costs more, but we want a guarantee that it will work. Thank you for affording me this opportunity to test your product.

[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.

[This review was collected as part of a promotion.] This Colgate Optic White Advanced toothpaste is great. There is a slight foam action in the beginning of your brushing. The texture is great, smooth and provides a sleek and clean finish. The product is vegan and uses peroxides. The toothpaste definitely provided whitening and protection. Would highly recommend.

[This review was collected as part of a promotion.] This toothpaste is great. Leaves your breath feeling clean immediately. I am a coffee drinker, so to have a toothpaste that can help with stain prevention is perfect. I will continue to use this toothpaste.

[This review was collected as part of a promotion.] I loved my free sample of Colgate optic white stain prevention I received from Home Tester Club. It works great and leaves your mouth feeling refreshed. It works great on coffee stains . I would definitely recommend.

[This review was collected as part of a promotion.] I am very Impressed with Colgate Optic White Advanced toothpaste as not only did it leave me with EXTRa clean fresh breath( almost as if just used a mouth wash), but I could see a difference in the shade color of my teeth after only just a couple of uses! My teeth have definitely gotten at least two shades wider since using this toothpaste I've been using for roughly almost 3 weeks now! The claims are deeply whitens for up to four shades... I am two shades in and can't wait for the next two! This toothpaste also has stain prevention, is enamel safe and also provides protection against cavities. I'm loving the core, herbal minty wintergreen flavor/ sensation! This is a MUST HAVE for those wanting whiter teeth and helping your teeth and gum stay healthy all of the time! Five star product for sure- i've already started to recommend to family and friends!

You guys need to try the toothpaste that I just used . I bought it because my teeth were really yellow. It's called Colgate Optic White Advanced. I brushed my teeth really good and vigorously for 5 minutes. THAT TOOTHPASTE IS THE BEST TOOTHPASTE IVE EVER USED! When I was done brushing my teeth, my teeth looked whiter, my teeth felt stronger, and it felt like I just got my teeth cleaned at the dentist office. IT WAS THAT GOOD! You guys need to start buying this. It deeply whitens your teeth up to 4 shades. I still feel I nice coat of what ever came from toothpaste on my teeth, and it feels like my teeth are stronger.

[This review was collected as part of a promotion.] I see it for two weeks for me to have an honest opinion, I have been using it everyday mornings and nights and I can honestly tell you that it's amazing. It has a great taste and my teeth are whiter.

[This review was collected as part of a promotion.] I really like that it foams up really makes you feel like you're getting your teeth really cleaned and the flavor is not overpowering you're not gonna carry the flavor all day your mouth which is really annoying and I really like the design on the bottle standalone
