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

I'm a senior and I love coffee. For a long while I noticed my lower teeth in photos looking dim dingy and yes...yellow. I have tried some methods in whitening but nothing seemed to help much. I took the leap and bought this first at the drug store. I noticed a difference almost right away. I've bought it ever since through Amazon (because it is a similar cost as in the store and I don't have to go get someone to unlock the case, a huge time consuming hassle). It actually does make your teeth look much younger. Highly recommend.

Costco has it at a better price at 4.01oz with a 4 pack instead of 3.

After a few weeks of using this, I definitely noticed whiter teeth, and this toothpaste has such a strong taste, it will leave you feeling refreshed until the next meal. However, this particular flavor I got is really bad. It's very strong and will leave you refreshed, but when brushing, it tastes just awful. It's not even a mint flavor, but rather a strong chemical flavor. This might be a deterrent to good brushing habits for some, but if you're keen on this toothpaste I'd highly recommend going with the other flavor if you can find it.

My teeth are noticeably whiter two weeks in - I'm so happy! Taste isn't amazing but you just need a small drop and it's worth it in my opinion. This works even better than their other whitening products.

I've been using this product for about two months now. I was skeptical about its ability to whiten my teeth but it worked, and the whitening was better than I expected. For me there was little change even after one month -- you do have to persist. I plan on continuing to use this product.

This is a nice tooth paste and after a couple times of using it, it seems to have whitened my teeth just a little bit. I used it twice a day for 2 weeks as indicated. I took before and after pictures of my teeth and after comparing, it really wasn't much of a difference. The shade looked the same actually and not whiter. I'm not sure if it looks whiter in the beginning as like a placebo effect or what, but after comparing 2 week photos I wasn't able to tell a difference. The price isn't bad and the taste is what you expect. I'm not sure if I would try it again.

Best toothpaste on the market. Too bad Colgate pulled the Enamel Repair formula off the shelves. This toothpaste is so good they knew it was a threat to the dentist industry. So they no longer carry it in stores since the "industry" would lose money if people had a product that actually prevented cavities. They do still carry the whitening and fresh breath versions but not the enamel strength one which contains the highest amount of hydrogen peroxide. Sad

This is strong and works. And it works quickly. It won't be necessary to use this daily, three times a week is probably best. I hold it in my mouth for about a minute, as well. This tube doesn't last long, however. But I suspect my husband has been sneaking some for himself, that maybe why it doesn't last long.
