Has anyone here ever regrown their "permanent" teeth naturally? I came across a Paleo blog where people were talking about regenerating their teeth after losing their old ones and was reminded of how I lost my one of my premolars to tooth decay when I was little. I remember yanking it out by myself in a rather lackadaisical manner, actually glad that the rotting tooth had become loose enough to be removed because I assumed that ALL teeth were supposed to be replaced by a second set. No one told me otherwise so when the new tooth popped up a short time later, I thought it was perfectly normal. I wonder if I could still regrow teeth as an adult (naturally, that is, without the use of technology). It would be a safe, easy and inexpensive way to remove a mercury filling that I have.. by removing the whole tooth!
