A tusk from an adult male elephant weighs between 100 and 175 pounds, according to SeaWorld Parks and Entertainment, while a tusk from an adult female elephant weighs between 40 and 44 pounds. The heaviest tusk ever recorded weighed in at 220 pounds.
The tusks of Asian elephants are smaller than those of African elephants. Both African and Asian elephants have 26 teeth, including their two tusks, which are their upper incisors. Elephants have 12 molars; each is the size of a brick and weighs 4 to 4.5 pounds.
New teeth develop at the back of the elephant's mouth. They move horizontally in the mouth until they become worn out as they approach the front. An elephant's teeth are replaced six times during its lifetime.
