How strong is the human bite force, and how does it compare to animals? - #4825

Anonymously

I recently heard that the human bite force is pretty strong, but I don’t know how it compares to other animals. What exactly is the human bite force, and how is it measured? I read that it’s around 160 psi (pounds per square inch)—does that mean we can bite through tough materials? Also, does jaw size and muscle strength affect how powerful someone’s bite is? How does the human bite force compare to animals like dogs, lions, and sharks? Are there any risks of damaging teeth if someone bites down too hard? Also, do certain conditions, like bruxism (teeth grinding), affect bite strength?

The human bite force is around 160-200 psi (pounds per square inch), which is strong enough to break down food but not typically powerful enough to bite through tougher materials like bones. This force is measured using specialized equipment that determines the pressure applied when a person bites down, often in a controlled clinical setting. Jaw size, muscle strength, and dental health all contribute to how powerful someone's bite is. Stronger jaw muscles or a larger jaw can generally produce a stronger bite force. When compared to animals, humans have a relatively weak bite force. For example, a dog’s bite force can range from 200 to 700 psi, while lions and sharks have bite forces in the thousands of psi. These animals’ jaws are designed to bite through meat, bone, and tough materials. Biting down too hard can potentially damage teeth, especially if you’re biting on something hard or have weakened teeth. Conditions like bruxism (teeth grinding) can put extra stress on your teeth and jaw muscles, potentially affecting bite strength and leading to tooth wear, pain, or damage over time.
