Which shark has the most teeth?

Which shark species holds the record for most teeth?

Most of these enormous predatory fish have around five rows of teeth along each jaw, typically containing 20 to 30 triangular teeth per row.

The bull shark holds the dental record with a terrifying 50 rows of sharp teeth, and with up to 1,500 teeth at any time, many argue it is the most dangerous shark in the ocean. This is one award-winning smile you should probably avoid, with the bull shark being responsible for the 3rd most attacks on humans, as it likes to loiter in shallow waters where they are most likely to come across people.

Sharks opt for quantity over quality and prepare to lose their unrooted teeth by growing back-ups


A shark’s teeth aren’t anchored by a root like human teeth, and at least one tooth falls out of its mouth per week. Holes are quickly filled with a new tooth from one of the many hidden inside the jaw membrane. Teeth move forward like a conveyer belt to occupy gaps and keep a shark’s bite as deadly as possible.

The shape of these teeth is dictated by the shark’s diet. Catsharks, for example, have thick plate-like teeth for scooping up shelled crustaceans from the ocean floor. Great white and tiger sharks have serrated teeth for tearing through seal flesh and mako sharks have needle-shaped teeth to immediately immobilise slippery fish.
