I usually don't make any kind of reviews unless I absolutely love it & this is absolute love.
I've been using Birch daily for some time, and I'm a pretty big fan. My teeth are noticeably whiter. It tastes good and because it uses white charcoal, it doesn't leave my mouth, toothbrush, sink, etc. covered in black soot.

I've been using it for about 2 weeks now and I've noticed that my teeth are already whiter. It has a nice mint flavor - not too strong. My mouth feels cleaner somehow using this over my regular toothpastes. My mouth definitely feels fresh all morning. I definitely recommend it.
