Crocodile teeth facts 

With their sharp, dagger-like teeth, and extreme biting force (the strongest in the animal kingdom) crocodiles are intimidating dinosaur-like creatures who both humans and animals try to avoid wherever possible.

Paleobiologist Gregory M. Erickson and colleagues put all 23 living crocodilian species through an unprecedented bite test. Saltwater crocodiles—slammed their jaws shut with 3,700 pounds per square inch (psi), or 16,460 newtons, of bite force. By contrast, you might tear into a steak with 150 to 200 psi (890 newtons). Hyenas, lions, and tigers generate around 1,000 psi (4,450 newtons).

How many teeth does a gharial have?

How many teeth does a baby crocodile have?

Despite baby crocodiles having much smaller appetites than their larger adult counterparts, they still hatch with a rather impressive amount of teeth for a young reptile – around 60 to 80 individual teeth, depending on the species. 

Additionally, baby crocs also begin their life with a special adaptation that is only found in certain species of reptiles, birds, and monotremes (platypuses and echidnas) – the egg tooth.

What is an egg tooth?

Although the inside of their mother’s egg is the perfect place for baby crocodiles to start their initial development, they will soon have to escape these confines if they want to avoid suffocating. 

As they grow larger, baby crocodiles naturally require more oxygen, and the only way for them to get this is by hatching out into the big wild world. Thankfully, this task is made easier by the presence of their handy egg tooth.

Interestingly, the egg tooth isn’t a real tooth, it is a sharp piece of hardened skin that is located on the top of their snouts. Using this protrusion, the hatchling crocodiles will rub their face against the inner membrane of the egg until they manage to tear it apart. 

From here, they will use their nose to push against the egg until they can break free of the outer part of the shell. 

The baby crocodiles will stick their snouts into the air and remain still for a few hours until they are ready to completely leave the egg. At times, some baby crocodiles may need encouragement from their mother, who will take the egg in their mouth and gently push down on it, encouraging the baby crocodiles to finally break free.

What type of teeth do crocodiles have?

Crocodiles, unlike most species of animals, have heterodont dentition. Essentially, this means that their teeth are differentiated into different forms like incisors, molars, and canines, the same forms as human teeth.

Can crocodiles grow teeth back?

Famous for their sharp and deadly gnashers, crocodiles are classified as a polyphyodont, a species of animal with the unique ability to replace their teeth. Unlike humans, crocodiles often lose or break their teeth when hunting or chomping down on the tough hides of prey. 

Thankfully, this is not a problem for the ancient reptiles, as a new tooth will develop as soon as an old one is broken or lost. Interestingly, most crocs rarely have all their teeth at one time, and instead, continuously lose and grow them through the course of their lives.
