Whether you’re curious about sharks or have spent time around them, you’re probably wondering how many teeth sharks have.

Here’s what you need to know about sharks and how many teeth they have.

How many teeth does a shark have?

Common species of shark have 50 to 350 teeth at a time.

Over their lifetime, sharks will have thousands of teeth, and some shark species will have 20,000 or more teeth.

Sharks’ teeth are in rows in their mouths, with anywhere from 5 to 15 rows of teeth, and some species of sharks have even more.

These rows of teeth are not always in use but they are there to move as sharks lose their teeth.

The exact number of shark teeth will depend on the species of shark.

How many teeth are sharks born with?

Unlike humans, shark pups are born with a full set of teeth.

They may not have as many rows of teeth as fully mature adults would have, but baby sharks are independent at birth.

They swim away from their mother and immediately begin hunting on their own, which is why they are born with a full set of teeth.

Why do sharks have so many teeth?

Sharks have a large number of teeth due to the way their bodies are built.

Sharks have no bones.

Instead, they are made of tough cartilage.

This allows them to move quickly and efficiently in the water.

Since sharks have no bones, their teeth are not as secure in real jaws as human teeth.

Therefore, they lose teeth very easily, which means they must have other teeth to replace the teeth that have fallen out.

The new teeth move into place in a conveyor belt fashion, and it takes approximately 24 to 48 hours for a new tooth to come in and replace the lost tooth.

Sharks use their teeth to hunt, so if they don’t have other teeth because they lose them, it will be a big problem for them.

How many teeth does a shark lose in its lifetime?

Dangerous Sharks in the Aquarium

It is estimated that sharks will lose 20 or more teeth per week, meaning that sharks may lose several dozen teeth per month.

Adding this to a shark’s lifespan of 20 to 30 years, this means that sharks can lose 20,000 or more teeth throughout their lifetime.

Do sharks have teeth when they bite something?

Since shark teeth aren’t protected by a bone, they can lose them so easily, so they pop out when they bite into something.

For this reason, people who are victims of a shark attack may have a shark’s teeth embedded in their skin where the shark bites them.

According to experts, the number of teeth of sharks is almost infinite.

Although they may lose thousands of teeth over their lifetime, they can continually regenerate new teeth to maintain the number of teeth they have lost.

There have been no reported sharks that have lost teeth, and it is believed that sharks will continue to grow new teeth as often as needed.

Sharks are thought to have evolved an almost unlimited number of teeth because of their dire need for teeth to hunt and survive.

Which shark has the most teeth?

whale shark with large open mouth underwater

Of all the shark species, the whale shark has the most teeth.

The whale shark is the largest species of shark, but also one of the friendliest.

Whale shark teeth are considered non-functional.

What are the Different Types of Shark Teeth?

Lower teeth in preserved jaws of sharks

Sharks can have four main types of teeth, depending on the exact species of shark.

Species that have needle-like teeth include the bull shark and the blue shark.

3. Shark Teeth of Shark Lower and Triangular Upper

The pointed lower and triangular upper teeth are typical shark teeth that people think of when drawing a shark’s mouth.

These teeth are needed for hunting and biting large mammals.

These teeth have serrated edges that can actually rip off prey.

The Great White Shark is one of the most famous species of shark to have these teeth.

4. Non-functional Shark Teeth

Some sharks have teeth but they are not needed.

Species such as whale sharks or basking sharks feed only on plankton and do not need teeth to hunt their prey.

However, they still have teeth which means they serve no purpose in a shark’s mouth.

It can be extremely difficult to tell how old a shark’s teeth are.

If they are fossils, this could mean that they are potentially 10,000 to tens of millions of years old.

A good way to try to determine the age of a shark’s tooth is by taking a sample of the sediment in which the tooth was found.

This test can be done to determine the approximate age.

However, if a shark tooth is found washed up on the beach, the sediment will not be helpful.

Some experts who work frequently with shark teeth can determine the species of shark from which the tooth came from and then give an approximate age of the tooth.

Why do some sharks have black teeth?

shark teeth

Shark teeth are colored differently because of the sediment in which they are mixed.

This is why shark teeth are not all white.

Some will be lighter in color, but others may be brown or black.
