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

I’ve used this twice a day for two months with no change to the whiteness of my teeth. The hydrogen peroxide makes the toothpaste not taste good.

Use this product for three weeks. Took pictures of my teeth (in the same spot and same lighting) and saw no appreciable difference. Two stars for the fact it still works as a toothpaste, nothing more.

Definitely quickly whitened my teeth. Definitely taste like a mouth full of peroxide though

I use Colgate Optic white 3% peroxide daily. Its very clean and makes my teeth brighter. This 5% is even stronger. Its a great pick me up whitening toothpaste, better than any other toothpaste that Ive used.

My toothpaste does not have a mint flavor. Its actually really gross. I am still using it, but I am also having to add a mint toothpaste to it. Is mine bad?

The flavor is not the greatest.

Very strong flavor.

Theres hardly any toothpaste in the tube. Its mostly filled with air.

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..

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. Its very strong and will leave you refreshed, but when brushing, it tastes just awful. Its not even a mint flavor, but rather a strong chemical flavor. This might be a deterrent to good brushing habits for some, but if youre keen on this toothpaste Id highly recommend going with the other flavor if you can find it.
