I don't know anybody else who does this, but I used an idea I read in Family Fun magazine six or seven years ago. We instituted the "World-traveling Tooth Fairy." In advance, I collected coins from many different countries, and with each lost tooth, the tooth fairy left a fun coin and a short note about where she had picked it up, or why she thought the girl would like it. I have twin daughters also, and they are now eleven - the tooth fairy left these coins and notes until the girls were almost eleven. (And they, too, lost teeth at different intervals - this wasn't a problem. The girls are different in SO many ways, that this was just one of those.) ---because I had saved coins over the years, and I had friends and family members who could give to my Tooth Fairy bank, this was not a problem. Another idea that a friend of mine institutes is "a book and a buck" - with each lost tooth, a child gets a book and a $1 bill or coin.
