The lion’s 30 adult teeth include 12 incisors, four canines, 10 premolars, and four molars. At 3 months of age, a lion’s permanent teeth begin to erupt through the gums and continue to develop until 13 to 15 months of age.
On average, animals have 20 to 40 adult teeth. Generally, marsupials have 30 to 50 teeth. Animals that do not belong to the mammalian order that consume insects tend to have considerably more. The lion’s canine teeth are designed to sever the spinal cord of prey by squeezing between the cervical vertebrae; they also separate meat from bone while feeding. The jaws of a lion can only move vertically and exert roughly 690 pounds of force.
