Review title is Simply Disgusting..... [SEP] I decided to give this product a try.  It is probably one of the most revolting products I have ever used.  The charcoal powder is put on a wet toothbrush and then you brush.....and the taste is disgusting.  The black spew dirtied the sink, and required me scrubbing it after each use.  As for the whitening properties, I could see no difference with the exception of the fact after scrubbing my teeth with this noxious powder, I had to brush my teeth with my toothpaste 3 separate times to get rid of the black mess.  I was really disappointed in this product, and couldn't give a recommendation for this.  It was simply disgusting.
