How long are sharks teeth?

The length of a shark's teeth depends on the type of shark. The largest living shark, a whale shark, has teeth that are relatively small, even tiny. The smallest living shark, the dogfish, also has tiny teeth, while the great white shark has teeth the size of about 36 mm, or 1.43 in. But the largest shark to have ever lived, the megalodon, could grow teeth longer than seven inches long.
