Elephants have a total of 26 teeth: two incisors, which are the tusks (tush in female Asian elephants), plus 12 premolars and 12 molars. An elephant can go through six sets of replacement molars throughout its life.
These teeth are large, grinding molars that they use to chew up their food using a backward-forward grinding action. As these teeth begin to wear out, they move forward towards the front of the elephant’s mouth. As they move forward, new molars come in at the back of their mouth.
