How Many Teeth Do Sharks Have?

If you were trying to take an underwater selfie with a shark in the ocean, you might say “Say cheese!” You might think that sharks have nice shiny teeth that would make for great photos, right?

But wait, you wouldn’t want to take a selfie with a shark? Why not? Oh, because of their sharp teeth…got it. So, just how many teeth do sharks actually have?

The number of teeth a shark has depends on the specific type of shark. There are numerous different types of sharks in the world’s oceans, and the number of teeth they possess can vary greatly.

For instance, great white sharks have around 50 teeth at any given time (their “working” teeth). However, like most sharks, they have multiple rows of teeth in various stages of development to replace the ones that fall out. Some sharks can have over 300 teeth in different stages of growth within their mouths at any one time!

Unlike human teeth, shark teeth are not very strong and tend to fall out easily. But this isn’t a problem for sharks, as they are constantly producing new teeth to replace the ones they lose. In fact, some sharks can have over 50,000 teeth throughout their lives!

Many sharks have teeth arranged in layered rows. Both their upper and lower jaws can have 2-3 or even up to 15 such rows. Since their teeth do not have roots, they break off easily and may only last for about a week. However, new teeth can move forward to replace lost teeth within a day to a couple of weeks. The skin inside a shark’s mouth moves new teeth into position like a conveyor belt.

Although it may seem like a disadvantage to be constantly losing teeth, this system works well for sharks. Over time, sharks have developed powerful jaws that allow them to have a strong bite, making them the top predators of the oceans.

When they bite into a tasty meal, they often lose several teeth. If they couldn’t easily replace those teeth, their powerful bite would be of no use. Therefore, the ability to replace teeth easily has actually helped sharks develop their strong bite.

Since sharks go through so many teeth in their lifetime, fossilized shark teeth can be easily found on the shores of many beaches. Shark tooth hunting has become a popular activity for visitors to beaches with an abundance of shark teeth.
