Did you know that the human jaw is capable of exerting up to 125 kg of force in a single bite? On average, the female bite registers at 50 kg, while the male bite registers at 70 kg. There is a wide variance in pressure between the front and the back teeth, with the back teeth (molars) bearing most of the stress.
Can the human jaw break itself?
Trauma or broken jaw
Trauma can occur during an accident, fall, assault, or a sports-related injury. Trauma can result in your jaw being broken, fractured, or dislocated. A slight fracture will usually heal on its own. A major break in the jaw could require surgery to help the jaw heal properly.

Who has the strongest human jaw?
In August 1986, Richard Hofmann (b. 1949) of Lake City, Florida, USA, achieved a bite strength of 442 kg (975 lb) for approximately 2 sec in a research test using a gnathodynamometer at the College of Dentistry, University of Florida, USA. This figure is more than six times the normal biting strength.
Can the human jaw bite through bone?
However, uncooked mammalian cortical bone is extremely resilient. The limiting factor is that the human jawbone is made of uncooked mammalian cortical bone: clearly the human jawbone cannot bite through a thicker bone than itself, because it would break itself first.
Can humans bite off fingers?

Lions are powerful creatures, but they do not have the strongest bite. They bite with 650PSI (other estimates claim 1000PSI), and they have 4-inch canine teeth that can bite deeply into animals. Hyenas have one of the strongest bites in the animal kingdom, over 1100 PSI.
How strong is a Megalodons bite?

People with this condition gnaw at and eat their skin, leaving it bloody, damaged, and, in some cases, infected.
How much bite force does it take to bite off a finger?
In 1956, tests were conducted on cadavers to determine the force needed to successfully sever a finger and scientists discovered that it takes about 1,485 newtons just to cause fractures. That’s right–fractures. Bones, tendons, skin, and nails beef up our fingers more than you could imagine.
Is it possible to be born without a mouth?
Otofacial syndrome is an extraordinarily rare congenital deformity in which a person is born without a mandible, and, consequently, without a chin. In nearly all cases, the child does not survive because it is unable to breathe and eat properly.
