Amazing Facts About Shark Teeth

1) Because they’re born with a full set of teeth shark pups can start hunting when they’re 1 day old.

2) Sharks can’t get cavities so they don’t need to floss!

3) Sharks lose at least one tooth per week but they can grow new ones in a day. 

4) Sharks lose thousands of teeth in their lifetime. It’s a good thing they don’t have pillows or they would keep the tooth fairy really busy!

5) The giant megalodon shark is extinct so its teeth are valuable collectors’ items. They can measure half a foot long and some weigh more than a pound.

6) Unlike human teeth shark teeth don’t have roots to keep them in place. They can fall out when a shark bites into its dinner.

7) The shape of a shark’s tooth depends on what it eats. Some sharks spear slippery fish with long, needle-like teeth and others crush crabs and clam shells with thick, flat teeth.

8) Over the course of thousands of years shark teeth turn into fossils on the ocean floor.

9) On fossil websites rare shark teeth can sell for thousands of dollars.
