A shark can have as many as 50,000 teeth in it's lifetime with 5 to 15 rows in it's upper and lower jaw.
Shrews can have between 30-32 teeth depending on the species. They have sharp incisors for gnawing and tearing food, as well as molars for grinding.
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).
Adults naturally have 32 permanent teeth. In some cases adults can lose 1 to 4 wisdom teeth through surgery if they are impacting other teeth. No adult teeth are lost naturally though.
The Tiger shark can have up to 3,000 teeth in its body at a time. Over its lifespan it can have up to 30,000 teeth!The Sand Tiger Shark can have about 3000 or more teeth at once. Throughout its lifetime it can have about 30 000 teeth.
for natural teeth, most people have a set of baby or milk teeth first. When these fall out as the adult teeth grow in.Some rare cases of multiple rows of teeth have been noted. Loss of the set of adult teeth may require full or partial artificial sets of teeth or dentures. These can be replaces many times.
Humans have two sets of teeth in their lifetime.
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.
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 are constantly shedding and regrowing their teeth. Over a lifetime they can lose and grow up to 50,000 teeth.
