Here are four easy ways to say the same idea, using words a 6-year-old will understand:

  • If a shark loses a tooth, a new one slides up to take its place.
  • When a shark's tooth falls out, another tooth moves forward.
  • A shark's old tooth can drop out and a new tooth pushes forward.
  • Sharks have spare teeth that move up when one comes out.

Quick step-by-step explanation:

  1. Sharks have lots of teeth in rows.
  2. Sometimes a tooth falls out.
  3. Right away, the tooth behind it moves forward so the shark always has teeth to eat with.
