20,000 Teeth In a Lifetime?!?
Humans only get two sets of teeth in their lifetime, our baby teeth (which can start growing in the womb) and permanent adult teeth. Nature has a lot more variety than that, however. Some animals like sharks continually produce new teeth throughout their life, and can have over 20,000 teeth in a lifetime. Others like horses and rodents have open-rooted teeth that never stop growing; they simply wear down the exposed part while chewing. While we don’t take care of the dental needs of our finned or four-legged friends, it’s an important part of your pet’s health to have their teeth checked regularly by a veterinary dentist.
