What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do crocodiles grow new teeth all their lives?

The Big Idea

Crocodiles lose teeth all the time. But they never run out! Why do they grow new teeth all their lives?

Wearing Down

Step one: Wearing Down. A crocodile's teeth wear down or break. But it can grow new ones again and again.

A Spare Inside

Step two: A Spare Inside. Each tooth is hollow, and a replacement is waiting inside. It moves up when the old one falls out.

Many Sets

Step three: Many Sets. A crocodile might replace each tooth dozens of times in its life. Some estimates suggest an alligator can go through thousands of teeth. You only get two sets, so brush well!

A Closer Look

Let's take a closer look! Wears out. Waits inside. Dozens of times. Two sets only.

Quick Facts

Think Like a Scientist

Now, think like a scientist! Look in a mirror. Count your teeth. Draw a crocodile mouth. Draw a new tooth growing inside each old one. How many teeth did you count?
