His group at the University of New South Wales have studied the strength, sturdiness and biting power of the sabre-toothed cat , the great white shark , and the Komodo dragon. Now, he has turned his attention to a predator whose skull is far less impressive but yields surprises all the same — us. Some have even suggested that our weedy jaw muscles made way for our large brains and thus facilitated their evolution. The notion of weak human chops was based on very unrefined models that treated our jaws as two-dimensional levers. Of course, in real life, we chew in three glorious dimensions. To really understand how strong our mandibles are, we need to add that third dimension to the models.

Human bite force

Updated: Mar 2, Do you know which animal has the strongest bite? Our jaws have evolved to be quite efficient -- in fact, if our skulls were scaled to the same size, human jaws would actually be more efficient and powerful than primates! The average human bite force is between PSI pounds per square inch. However, this pales in comparison to many wild animals, many of which use their teeth not only to chew, but also to grip and tear. As any veterinarian will tell you, any dog bite can be dangerous due to their sharp teeth and potential of bite wound infection. Always treat dogs and their teeth with the respect and care they deserve! FunFact : Wolves which all domesticated dogs were descended from have an average bite force of PSI. Spotted Hyenas have a fearsome bite force of PSI. Polar Bears have the strongest bite force of all bears, with a bite force of PSI. Gorillas are mainly plant-eaters - the only non-carnivore on this list! They use their powerful jaws to chew and tear through bark and roots, and their large teeth are also used to display force and aggression. Bull Sharks have an estimated max bite force of PSI, and the strongest bite force of all sharks. Jaguars have the strongest bite force of all big cats at PSI. The Hippopotamus has the strongest bite of all land animals at about PSI.

Males can grow up to 7m in length and weigh in at around 1,kg, with the females being slightly smaller. To get the FREE science newsletter in your inbox! Open in a separate window.

This is possible with the help of such a huge bite force. One reason is that our jaws are smaller compared to other animals. Additionally, our teeth are not as sharp and pointy as those of other animals. These factors play a big role in our weaker bite force. However, our molars exert a bite force that beats the likes of primates like orangutans and gibbons, but gorillas and chimpanzees have stronger bites. Although human bite force is quite low, it is quite impressive for primates our size. Humans have found ways to adapt and overcome our weaker bites.

Analysis of variance was used with MBF as a dependent variable, age group and gender as random factors, and BMI as a control variable. In young adults, the female force became greater the males, then decreased in adulthood. The masticatory function is acquired by eating experiences and is especially influenced by the consistencies of food. The maximum bite force MBF , based on masticatory function and related to individual anthropometric characteristics such as sex and age, has been discussed in the literature. The masticatory process consists of cutting, grinding, and spraying steps.

Human bite force

Bite force quotient BFQ is a numerical value commonly used to represent the bite force of an animal, while also taking factors like the animal's size into account. The BFQ is calculated as the regression of the quotient of an animal's bite force in newtons divided by its body mass in kilograms. The authors predicted bite forces using beam theory, based on the directly proportional relationship between muscle cross-sectional area and the maximal force muscles can generate. Because body mass is proportional to volume the relationship between bite force and body mass is allometric. Consequently, small species would be expected to bite harder for their size than large species if a simple ratio of bite force to body mass is used, resulting in bias. Applying the BFQ normalizes the data allowing for fair comparison between species of different sizes in much the same way as an encephalization quotient normalizes data for brain size to body mass comparisons. It is a means for comparison, not an indicator of absolute bite force. In short, if an animal or species has a high BFQ this indicates that it bites hard for its size after controlling for allometry.

Bull shark bite force is used for: A widely varied diet, from oysters and turtles to baby hippos and other sharks. These factors play a big role in our weaker bite force. Check our past science newsletters. Reliability of maximum bite force measurements in age-varying populations. Recent Posts See All. Bite force determination in adolescents with and without temporomandibular dysfunction. Bite force also declined between 12 and 19 years of age. Animals Single orca seen killing great white shark for first time ever. The images below show an example of these virtual models, displaying the forces that act upon the skulls as they chomp down on the second molar. But our jaw muscles can produce a strong bite through less effort than those of other primates. Table 2 Statistical analysis of variables and age group—gender interaction with no significant relation to the maximum bite force. Jaguars have the strongest bite force of all big cats at PSI.

Braz Oral Res. In fact, human ancestors had stronger bites than modern humans and losing strength in the jaw through adaptation allowed for more space for the brain, and higher intelligence. How is Bruxism Diagnosed and Treated? Male participants had higher values for MBF compared with girls in the pubescent period. Bite force and occlusion. The average strength of a human bite is pounds per square inch PSI , but this pales in comparison to nature's champion chompers. The inclusion criteria of the sample were as follows: be at least 11 years old for female participants and at least 12 years for male participants, with a maximum age restriction was 60 years, and have complete permanent dentition and absence of dental mutilation, regardless of the type of dental occlusion. This difference decreases from the age of 25, since the force for the male participants increases less abruptly, as shown in Table 3 , approaching the average for female participants. Monthly Newsletter. Spotted Hyenas have a fearsome bite force of PSI. What is the bite force of a human? Humans have weak jaws to eat cooked food. Subsequently, dental conditions were assessed and also the dental composition was examined through clinical observation to ensure the presence or absence of dental mutilation and orthodontic treatment. Gorillas are mainly plant-eaters - the only non-carnivore on this list! Science These 4 medicinal herbs may help keep men healthy.
