This is too fine of a grind.
I've had teeth whitening activated charcoal before, but this one is just too fine of a grind. Try to put it on a wet toothbrush, and watch is swirl everywhere like fairy dust. Dry powder is fine, if you blow it off the surface IMMEDIATELY.<br />But let it touch just a drop of water, and it's everywhere. It doesn't really whiten, either.
