Never needed braces. I am missing my two adult molars on the bottom. I had all my baby teeth. I had my one baby tooth where the adult tooth never came in on the one side until I was in my mid 20s.
They say humans are evolving to have less teeth. We don't need to work as hard chewing rough food as in the past.
YOU DON'T NEED TOO MUCH CHEWING POWER FOR TWINKIES AND CHEESEBURGERS.
