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 brushand 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 separate times to get rid of the black mess i was really disappointed in this product and could not give a recommendation for this it was simply disgusting
