AMAZING!!
I had been using the Crest HD whitening 2 step program off and on for about a week or two.  It made my teeth very sensitive so I couldn't use it daily.  I saw this at the health food store and thought I would try since I knew about activated charcoal and clay properties for the rest of the body.  I was blown away.  The FIRST time it whitened my teeth more than the other stuff in over a week.  The second time I was even more excited.  Now after a two weeks, I don't want to use anything else.  I actually am not a fan of tooth paste flavors. I use this, drink my coffee and no weird taste issues. I don't even want to use another toothpaste in the mornings!!  I use a Tom's brand mouth wash after if need be but I can tell my sensitive spots are lessening and I won't whiten another way again. IN the shower is easiest since it can be messy but I am getting good at the sink method by now. Presents for the whole family this year!
