Review (4/5): Teeth felt smooth & polished after 1st use
PURCHASED IN LOCAL HEALTH FOOD STORE (not on amazon)
Have been using for about a week. Tasteless, odorless and no ill effects so far. Teeth felt polished after 1st use, really smooth like i'd had a cleaning by hygienist. Not noticeably whiter but my teeth are not terribly discolored to begin with. I brush at night, keep my mouth fairly closed around the toothbrush and spit low into the sink with water running. After the first time I quickly learned how not to get black specks everywhere! I floss afterwards to ensure none of the bits are stuck in teeth.
I still brush my teeth in the morning with a fluoride free toothpaste (periobrite) and brush my tongue with close-up cinnamon toothpaste because I like the taste. I also do oil pulling with coconut oil occasionally. I was tempted to rate it lower due to the price as there are other activated charcoal toothpowders on amazon for half the price, but I haven't tried them to compare how many ounces, how long it lasts etc.
