I’ve been using Shine tooth powder for a few weeks now, and I have to say that my teeth feel the cleanest and smoothest ever. I think it’s the super-fine powder. Too early to see if it makes a difference in color or hardness of my teeth.
i also really like the tongue cleaner. I had a plastic spoon-shaped one that I hardly ever used because starting it back far enough made me gag, and the edges didn’t stay smooth with use.
The metal one is much more effective, being shaped so that I can start it way back, and then do each side of my tongue too. Easy to use and very easy to clean too.
