Let us say that another human bites you. It can certainly cause some severe damage to your skin and flesh.

But never as the damage as the sharpest and strongest teeth on some animals can cause.
In some unfortunate cases, it can be lethal.

The outcome of a shark bite
Animals with the sharpest teeth can cause serious damage to your body.

In animal teeth, you will find nerves and vessels, sensations of hot and cold, etc. Animals can also get infections, and their teeth can break, too!


Their teeth work like human teeth: they can bite and crush. But some big mammals can bite down with more strength. They can bite 30 times more potent than any human occlusion!

How is the strength of the occlusion measured? 

PSI - Pounds Per Square Inch.

The strength of the pressure of the occlusion (that means how hard you can bite and the power you can put down) is measured in pounds by square inch

It means you measure the pressure from one object against another applied on a square inch.

The higher the PSI number is, the stronger the bite is. Let's look at the world`s most dangerous bites in the animal kingdom.

What animal has the sharpest teeth?
