Colgate Optic White Pro Series Whitening Toothpaste with 5% Hydrogen Peroxide, Enamel Strength, 3 oz Tube

I rated this 4 stars because it does work to some extent and that is more than I can say for any other whitening toothpaste that I have tried. It also leaves your teeth with a bit of a polished look, which I think is probably how it works. It gets off surface stains, but it does not bleach deeper stains.

Very disappointed that product looked old and expiration date 3 days away! Returning!

I have been using this line of toothpaste since it came out. To start this constantly leaks from the container. It foams up a lot while brushing and the taste is absolutely disgusting! I’m used to this optic white line being a thicker consistency and having a minty/fresh taste. The flavor of this is so absolutely awful I drove to the store to purchase a different one and threw this away. I’m not even sure if this is the actual toothpaste because I looked and the same one I ran out of did not taste like this at all nor foam up. I would not recommend. It also did not whiten nor make my teeth feel clean

Taste great, which was a big concern. I can still feel the peroxide working 10 minutes after brushing my teeth. Fresh lasting feeling.

Works better than the dental tray whitening gel you get from your dentist. I had visible results from day one - or day two, rather - I brush in the evening..

get a different flavor, youll want to throw up after tasting this one

It really does make a noticeable difference right away

Here’s a before photo I took the day I received the toothpaste, a photo taken 1 week later, and a photo taken 2 weeks later. I see a difference. The flavor isn’t the best, it foams a lot, and I think the tube will only last me about a month, but I’ll probably buy it again.

It can be a bit hard on the enamel but that’s manageable as long as you don’t brush for 5 minutes

Im pleasantly surprised at how much I like this toothpaste. Im mid-60s and it has whitened my teeth. I have fillings on both of my next-to-front teeth that are very brown (coffee?). Ive had these stains for over 5 years. I have been using this for about a month. My teeth are whiter and the stains might be lighter, too. I feel like the peroxide is good for my gums. My teeth feel smooth and my mouth feels fresher. I just ordered my 2nd tube and my husband is going to try it. Next time I might get the Colgate Optic White Renewal 3% hydrogen peroxide because it has twice as much product for about the same price. I hope it will give the same effect on my teeth and gums. I have no issue with the taste. I dont notice a flavor. Just feels clean. Works for me.
