I've been using the product for 3 days and I'm delighted. However, after brushing my teeth on the third day, I noticed that one of my crowns had turned gray. I stopped using it immediately and switched to cleaning with baking soda once a day. The gray color hasn't gone away and I didn't use charcoal. I'm not saying the charcoal caused the discoloration. I'm not sure. But I'm afraid to keep using it and risk making it worse. Hope this works for you!
