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 is the potential danger of animal bites for humans?

Depending on various factors, including the type of animal, the size and strength of the animal, the location and depth of the bite, the presence of infection, and the promptness and adequacy of medical treatment, animal bites can vary greatly in severity.
There are several considerations:
  1. There are animal bites that can cause deep lacerations, tissue damage, or even the loss of limbs.
  2. Animal bites have the potential to introduce bacteria from the animal's mouth into the human body, resulting in infections such as tetanus, and rabies, or bacterial infections such as Pasteurella multocida, which is commonly associated with cat bites.
  3. Some animals like snakes, spiders, scorpions, bees, and wasps have venomous bites. These bites can put poisonous substances into the victim's body, which could cause serious reactions or even death if not treated quickly.
  4. Some parts of the body, such as the face, neck, or joints, maybe more dangerous due to the risk of damage to critical structures, such as blood vessels, nerves, or joints.
  5. Some people may be allergic to parts of certain animals' saliva or venom, which can cause allergic reactions that range from mild itching or swelling to severe anaphylaxis.
  6. Animal bites can cause serious problems like tissue damage, sepsis, or long-lasting pain if they aren't treated or taken care of properly.
  7. Rabies can be spread through animal bites, especially from animals like dogs, bats, raccoons, or foxes. Rabies is a fatal viral infection of the central nervous system that demands immediate medical care and post-exposure prevention to avoid the onset of symptoms.
Basic first aid and proper wound care can be used to manage many animal bites, but it's important to seek medical attention for any animal bite that breaks the skin. A quick medical evaluation and treatment can reduce the risk of complications and help the wound heal properly.
