How do crocodiles continuously replace their teeth throughout life?

Quick fact

Crocodiles have a stem-cell-based dental system that continuously generates new teeth to replace lost ones, with each socket hosting up to 5 replacement generations.

Why this is interesting

Crocodiles can go through 8,000 teeth in their lifetime—each tooth has a backup tooth growing right behind it, ready to take over the same day it falls out.
