I brushed twice daily for 6 weeks with Colgate's Optic White toothpaste and saw no difference in the whiteness of my teeth (as verified by selfie photos).

[This review was collected as part of a promotion.] Definitely a great toothpaste that brightens up my teeth in a flash. The flavor is nice and refreshing without being overpowering.

[This review was collected as part of a promotion.] I replaced my normal product with this product. It did clean my teeth very well. I think it would be great if it had a better taste.

[This review was collected as part of a promotion.] This toothpaste has a great taste to it without being overpowering. Im not sure about its whitening ability as thats a long term thing but it definitely removes stains for me.

[This review was collected as part of a promotion.] I love the way the Colgate Optic White Advanced makes my teeth feel after brushing with it!!! My teeth feel so smooth and have whitened my teeth since using!! I highly recommend this product.

honestly I started using it a few months ago and the change has been drastic in my teeth, I could say that they have lightened up to 3 tones since I started brushing my teeth with this product without a doubt so far it is my favorite!

I got this at my local grocery story. I love this brand and this specific optic white line since it definitely whitens my teeth. I see that it makes a difference to the shade of my teeth.
