There is no way to count them. A shark's teeth are constantly growing and replacing any that are knocked out, so there's just no way to figure out how many they will have.
They usually replace the teeth instead of losing them. But usually the teeth are replaced every two weeks. A lemon shark replaces its teeth every 8-10 days. Young great white sharks replace there teeth every 100 days and old great white sharks replace their teeth every 230 days. The cookiecutter shark sheds the whole lower jaw at once.
Sharks have multiple rows of teeth arranged in several layers. They continuously shed and replace their teeth throughout their lifetime, with some species capable of producing thousands of teeth in a year.
Many teeth fall out each time a shark bites., so in a lifetime sharks have about 2000 teeth. But I think the megaladon has about as much as the great white does, only much bigger. (at a time).
12,000,345 teeth
whale sharks have 3000 little teeth but they do not use many due to their special ways of feeding
Sharks' teeth are arranged in series; when one tooth is damaged or lost, it is replaced by another. Most sharks may have about 5 series of teeth at any time. The front set is the largest and does most of the work. A bull shark might have 50 "rows" of teeth, with 7 teeth in each "row" (one for each series). This would therefore be 350 teeth (approximately, since some rows might be incomplete).

The great white sharks actually have that many teeth and they have three rows of them. This applies to all sharks that they have many rows of teeth or just many teeth.
