How long does it take for a shark's tooth to grow?

Answer 1

Sharks have rows of teeth (flattened down) behind those they are currently using to bite with. If one breaks, one of these replacement teeth moves forwards (rotates up) to replace it withing 1 or 2 days.

The spare teeth are constantly replaced throughout the shark's life.

Answer 2

Sharks grow new teeth their entire life; they are constantly producing them. If you were to look into the mouth of a shark, you would see up to 7 rows of teeth waiting to replace the ones that fall out. (The teeth are secured by the gums alone, so they fall out easily). It's like a giant conveyer belt, and a new tooth can replace the old one in as little as 24 hours. Cool, eh?
