I figured it’s that they ate all the animal. They always boiled the bones and that strengthened their teeth.

I bet if you look at ancient people in tropical areas they had less teeth as well as less need for them.

Interesting, I would assume that prehistoric times required "perfect" teeth (and even overall geometry and jaw structure). You need a high quality grinding / cutting tool to rip meat easily.
