WORKS AS ADVERTISED!
What a delight to have found this teeth whitener that does its job.  Who would've thought that BLACK CHARCOAL, a mega stainer, can remove stains and restores teeth's original shade!  Mind boggling, but it sure works!  When using this product, I wear a disposable glove on the hand that I use to brush since this leaves stains around my fingernails that are hard to wash off.
