There’s something about sharks that just captures our attention. Maybe it’s their fearsome reputation or their sleek and powerful bodies.
When it comes to fear-inducing sights, sharks’ teeth might be one of the worst—which leaves us with some questions: how many teeth do sharks have? How big are their teeth? How many different types of shark teeth are there?
We have the answers to all these questions, so keep reading to find out.
How Many Teeth Do Sharks Have
Sharks are one of the most feared predators in the world. They have been around for over 400 million years and have had a reputation for being ruthless killers ever since, with their razor-sharp teeth that can tear through flesh instantly. But how many teeth do sharks actually have?
The answer may surprise you: sharks can have 50 to 300 teeth at any time. Many sharks have teeth that are stacked in rows. Counting both upper and lower jaws, a shark can have up to 15 rows of teeth.
Their teeth don’t have roots, which is why they break quickly and easily. Depending on the shark species, it can take weeks to months for their new teeth to come up. Given the circumstances, they can go through tens of thousands of teeth in their lifetime.
So, how is it possible for a shark to have so many teeth? Well, it’s all thanks to their unique tooth replacement system. As soon as a tooth is lost, another one moves up from the bottom row to take its place. This process happens over and over again throughout a shark’s lifetime.

How Many Teeth May a Shark Grow in Their Lifetime
A shark’s teeth are its most iconic feature. But how many teeth does a shark have in its lifetime?
Most sharks have 5–15 rows of teeth in their mouths at any given time. However, they constantly lose old and grow new teeth. It’s estimated that a typical shark may go through as many as 20,000–30,000 teeth in its lifetime.
The number of teeth a shark has depends on the species. For example, the great white shark has around 300 teeth in its mouth at any time. Comparatively, the whale shark has around 3,000 teeth.
How Many Different Types of Sharks Teeth Are There
With so many different types of sharks comes a wide variety of tooth adaptations. Each type of tooth is perfectly adapted to the shark’s diet and hunting style.
- Needle-like teeth are found on bull sharks and blue sharks. These teeth are long and thin—perfect for puncturing and holding onto their slippery prey and can be deadly.
- Pointed lower teeth with triangular upper teeth are the trademark of great white sharks. These are razor sharp, which makes them ideal to bite and slice through prey.
- Dense flattened teeth are common in nurse sharks and angel sharks. These teeth are designed for crushing and grinding up prey with hard shells like lobsters, turtles, crabs, and other hard-shelled animals.
- Non-functional teeth are found in megamouth, whale, and basking sharks. These sharks don’t use their teeth for hunting or eating because they “filter feed” themselves. This means they swim quite fast, with their mouths open, collecting small prey and plankton in their large gill rakers.
So there you have it—the next time you’re at the beach and you’re lucky enough to find a shark tooth, take a closer look and try to identify which type it is. With over 500 different species of sharks in the ocean, you are bound to find many distinct kinds of teeth out there.
6 Most Fascinating Sharks Teeth Facts
Did you know that sharks have been around for over 400 million years? And that their teeth are some of the most interesting things about them? Here are some fascinating facts about shark teeth:
- Sharks’ teeth are coated in fluoride, which makes them even stronger and more resistant to wear and tear.
- The largest shark tooth (so far) was found by Craig Sundell in the Ocucaje desert of Peru, and it belonged to a megalodon—a prehistoric shark that could grow up to 60 feet long. The tooth measured an impressive seven inches in length.
- Shark teeth don’t have roots like human teeth. Instead, they’re anchored in place by very strong ligaments.
- Sharks can lose up to 30,000 teeth in their lifetime.
- Sharks have the strongest jaws in the world. Unlike other animals, sharks can move both their upper and lower jaws.
- Sharks tend to swallow their own teeth with their food without noticing.
So there you have it, some fascinating facts about shark teeth. Next time you come across one (hopefully in a safe environment), take a closer look and appreciate all the incredible things about these creatures.

Frequently Asked Questions
How many sets of teeth do sharks have?
Sharks have anywhere from 5–15 sets of teeth. The number of teeth a shark has varies depending on the species.
Do sharks get cavities?
Sharks don’t get cavities because their teeth are covered in fluoride. Cavities are caused by bacteria that produce acids that break down the tooth enamel. The fluoride in shark teeth helps prevent cavities by making it harder for the bacteria to produce acids.
Do baby sharks have teeth?
Yes, baby sharks have teeth. They are born with a full set of sharp teeth and use them to feed on prey. Their baby teeth fall out as they grow and are replaced by adult teeth.
How often do sharks lose their teeth?
Sharks lose teeth every week, but they grow back very quickly. They have rows upon rows of teeth; as one falls out, the tooth behind it moves forward to take its place. This is how sharks always have a fresh set of teeth.
So, how many teeth do sharks have?
Sharks have 5–15 rows of teeth (depending on the species), which means they can lose up to thirty teeth a day without experiencing any problems. While this may seem like a lot, it’s important to remember that sharks are constantly growing new teeth to replace those that fall out.
In fact, some species of shark can go through up to 30,000 teeth in their lifetime.
