Animals with the sharpest teeth can cause serious damage to your body.

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


Their teeth work pretty much like human teeth: they can bite and crush. But some big mammals can bite down with more strength. They can bite 30 times stronger 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 strength you can put down) is measured in pounds by square inch

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

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