How much force can humans bite down with

The bite force exerted on teeth can be significant, and it varies across different parts of the mouth and from person to person. In general terms:

1. Molars:

The bite force is strongest in the molar area, towards the back of the mouth, where it can range from approximately 45 to 100 kilograms (kg) of force. Some studies even report higher figures in some individuals.

2. Incisors and Canines:

The bite force at the front of the mouth, where the incisors and canines are located, is typically less than in the molars. It can range from around 20 to 40 kg of force.

These figures are average estimates and can vary based on factors such as age, sex, dental health, and individual muscle strength. The maximum bite force in humans is generally less than that of many carnivorous animals, but it is adequate for the range of foods that humans typically consume.

It's important to note that regularly exerting maximum bite force can lead to dental problems, such as tooth wear or fractures, and temporomandibular joint disorders. Therefore, while the teeth and jaws are capable of exerting a significant force, they function best under normal, moderate forces during regular chewing.

What are the highest forces exerted on a bite?

The highest bite force measured in a human is a subject of some variability and debate in scientific research. However, it's generally agreed that the maximum bite force in humans can be quite substantial.

Regularly exerting such a high level of force on your teeth could lead to dental damage or temporomandibular joint (TMJ) issues. Most people use only a fraction of the maximum capacity (40kg-100kg) in their daily lives.
