Why do our teeth grow in less perfectly now?

[–] ajikeshi@lemmy.world 78 points 1 month ago* (last edited 1 month ago) (1 children)

because people with very bad teeth survive nowadays

Well, that mf didn't survive either... He's dead....

[–] abbadon420@lemm.ee 24 points 1 month ago (1 children)

But he lived a long and happy life. He died at the ripe old age of 35

Average age is not average for those that reached adulthood. Most adults still lived to decent ages unless you select for very dire situations, like the Black Plague, or specific outbreaks of violence, etc.

That is true, but tooth get worse when you grow older. So to die younger means you'll leave a nicer skull for archaeologists to find. The number 35 was arbitrarily chosen, but I now think your fact was slumbering in my mind when I chose that number.

But... teeth don't change arrangement as you age. Straight teeth are straight teeth unless rare complications happen like you have a lot of wisdom teeth and they shove the other teeth out of alignment.
