Interesting! So people in the first world countries do have more crooked teeth? I wonder if jaw shape could have anything to do with it too. I wonder if people with more narrow jawlines have more incidence of crooked teeth. But that is an interesting theory about the breast-feeding. It does benefit babies in so many ways.
