How many sets of teeth do sharks have?

Answer

How many sets of teeth sharks have can vary by species. Most sharks have around five sets of teeth. The front set is the main set of teeth, it does the largest amount of work and is the biggest in size. The rows get increasingly smaller, with the fifth row being the smallest and almost completely flush to the inside of the shark's mouth. The teeth shift around as the front teeth get damaged, with the other rows moving forward and a new tooth growing in the fifth row.
