I read somewhere bottle feeding versus breastfeeding is the difference for some of the crooked teeth problems of modern first world countries. Much less incidence of crooked teeth where mothers nurse their young.

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.
