Hope it works
I have used this only a few days, I hope it works. However, it is VERY fine and messy. I put it on a paper towel as it gets everywhere. the first day I tapped my toothbrush and it went everywhere.  I did buy charcoal tooth brushes and am VERY glad I did as they has thin, fine bristles.  I get it wet then dip it in the charcoal. it does get all over your outer mouth and takes a while to rinse out of my mouth
