Really works but watch out if you have sensitive gums

My dentist said this is a good product, and he was right!

Worked a little but not what is advertised

Good stuff, seems to be helping

I almost wonder if I got a prank box of black licorice flavored toothpaste. That's what it tastes like ti me. It awful. I only use it occasionally for that reason but it does seem to work well. I think it cleans my teeth

Working great so far

Great Product

Love this toothpaste.

Love this stuff! Makes my breath and teeth shine! It's strong and some people might experience sensitivity, but that is because it's powerful. I hope they don't stop making it!

I have used Optic White for years and loved it. This new formula with more hydrogen peroxide tastes chalky and does not freshen breath. I see no difference in whitening power. It doesn't foam up like the original formula. I'm going to have to find a new brand of toothpaste.
