Good luck, let me know what happens!
After a month of so of doing this, I felt what felt like a piece of the back of my bottom front teeth fell off, I was rather concerned! Pulled it out and inspected it; turned out, the oil pulling has loosened a piece of tartar and removed it!
Apparently this can also help regrow broken teeth, and I have a couple fillings that have fallen which I haven't replaced yet, so we will see... Good luck!
