There are some biological/anthropological theories out there postulating that so many folks need braces in Modernity because our food is so soft and rich that it requires much less work to chew compared to the foods of our ancestors.
If our caveman ancestors were chewing every last bit of meaty gristle and cartilage they could find in order to survive, then they probably spent a lot longer working their jaw muscles each and every day than we do with a tender Wagyuu steak, and that exercise made the muscles bigger and stronger. Those bigger denser muscles would be constantly pushing and pulling on their jaws as they age which – even though the effect would be very very small – would continuously affect your bone morphology as you grow and age.
The theory goes that our cavemen ancestors had straight teeth because that amount of jaw exercise was what the body’s bone-and-teeth development environment was evolved to properly work in… and our modern “lack of exercise” for our jaws affects our jaw development similarly to how near-total lack of walking and running exercise would affect a child’s leg-bone development.
