Colgate Optic White Renewal Teeth Whitening Toothpaste, Enamel Strength, 3 Oz Tube, 2 Pack

Overall, this toothpaste is OK, and may be good for some to use it for a short periods of time to whiten their teeth. But be aware that using it for a long time may lead to developing a brown hairy tongue - had to learn this first hand after only few months of use:((. Apparently, high peroxide content in the toothpaste is a known cause for hairy tongue (as it turns out), and after stopping the use of this paste, my scary looking hairy tongue cleared out in a week. I think I will stick with less fancier toothpastes from now on...

I had braces for 5 years, so I bought this in hopes of whitening my teeth. And it does a great job at that! I’ve used it twice now and I can already tell there’s a huge difference, and my teeth feel so clean- like I just came back from the dentist. The only con for me is that I have sensitive teeth (from the braces), and it does hurt them a bit. But it’s not to the point where I can’t use it. I’m hoping after a while it’ll help with that sensitivity since it’s not a natural thing- there’s a reason for it. But I would definitely recommend this for anyone needing a whitening paste!!

Apparently whatever the whitening product is, is not good to use in your mouth.

I have noticed that my teeth appear whiter with this product.

I bought this without much expectation，but this is great！The toothpaste has a nice taste that is not too sensitive for my teeth. More importantly，after two months of using it，my teeth are whiter.

As the tube is used up getting the last of the paste out is becoming difficult

Not sure of whitening capabilities and didnt love the flavor but better price than pharmacy.

Great amount for the price, it’s worth it but there are cheaper brands.

I used to alternate with sensitive toothpaste and another version from this line in order to combat a bit of sensitivity I had. This has really helped reduce sensitivity and while I still use the sensitive tooth paste a bit, it’s much less. My teeth are still bright and feel clean.

Have used this for several years now. It really does whiten your teeth several shades with just daily brushing. Great minty flavor. I am elderly and teeth tend to yellow a bit, but this brightens them right up. There are several kinds that you think are the same. They come in the same boxes. But it must say OPTIC WHITE
