Review title is Great Natural Tooth Whitener THAT WORKS! [SEP] Once I got over the shock of having BLACK teeth while I was brushing, I LOVED THIS STUFF.  Hahahaha...  I was panicked for a moment there but once I swished the blackness out of my mouth, all was good.  I noticed whiter teeth within 2 days!  I went a step further and added pelu powder and my teeth got even whiter!  Can't say enough good things about my Mud.  Will definitely buy more when this jar is gone!
