Also, and I think it was White Tiger, said that White Oak Bark could also do this. But when I looked it up, it said that it had some warnings about ingesting it. So I was afraid to put it on my teeth. I ended up getting Dr. Christophers Tooth and Gum, because it has this in it. After I oil pull, I dip my finger in it and coat my teeth, and let it sit there awhile. I've only been doing this for a couple of months, so I can't say 100% if this will work.
Anyway, I saw your post and wanted to give you that info.
