Tooth enamel

In humans, enamel varies in thickness over the surface of the tooth, often thickest at the cusp, up to 2.5 mm, and thinnest at its border with the cementum at the cementoenamel junction (CEJ). The normal color of enamel varies from light yellow to grayish (bluish) white.

is the hardest substance in the body. The shiny, white enamel that covers your teeth is even stronger than bone. This resilient surface is 96 percent mineral, the highest percentage of any tissue in your body – making it durable and damage-resistant.

What is the hardest a human can bite?

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 humans bite through bone?

Severance of a substantial length of fingertip by human teeth is rare and would require considerable force to cut through the supporting bone — see case report.

Can a human bite as hard as a shark?

While a shark's bite force has not been officially measured, it is estimated to be 4,000 lbf (pounds-force). That is twenty times more powerful than average human bite force, ten times more powerful than average wolf bite force, and seventeen times more powerful than average pit bull bite force.

Who bites Harder human or dog?

To give you a comparison, humans have an average bite force of 120-140 psi, and the Nile Crocodile has a bite force of 5,000 psi. The bite force of average dogs ranges somewhere around 230-250 psi, but some have more strength.

The hardest thing you can ask a human being to do is change.

Can u bite your finger off like a carrot?

There are cases of fingers being bitten entirely off, but such an act requires extraordinary force, far greater than 200 newtons of carrot-cutting power. You'll still have to bite through skin, tendons, and some flesh.

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.

The results revealed that human skulls, far from being weak, are quite tough and unusually efficient for their size. Our second molars can exert a bite force between 1,100 and 1,300 Newtons, beating the orang-utan, gibbon and Australopithecus but lagging behind the gorilla, chimp and Paranthropus.

The highest reading, 3,700 PSI, was registered by a 17-foot saltwater croc. “It's the strongest bite force ever recorded,” Erickson says, “beating a 2,980-PSI value for a 13-foot wild American alligator.”
