Why humans are the only species who get wonky teeth and require orthodontic treatment??
In: Biology
Changes in our diet: softer food means our teeth tend to “over-develop”.
> Corruccini reasoned that tooth size is preprogrammed to fit a jaw subjected during growth to levels of mechanical stress in line with a natural childhood diet. Subsequently, when the jaw does not get the needed stimulation during development, the teeth become crowded at the front end and impacted in the rear. He confirmed this hypothesis with experimental work on monkeys evincing that those fed softer diets had smaller jaws and impacted teeth.
