Closeup of jaw of Bull Shark, Carcharhinus leucas, showing development of rows of teeth. 
The teeth of sharks don’t have roots, so they usually fall out after 
about a week. However, sharks have replacements arranged in rows and a 
new one can move in within one day to take the old one’s place. Sharks 
have five to 15 rows of teeth in each jaw, with most having five rows. Photo credit:
