Elephants use these tusks as weapons, to dig up food, and to tear bark off of trees. When polished and kept clean, they are rumored to be very attractive to the lady elephants. After the tusks grow in, the elephant grows a pair of teeth in the back of their mouth. 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 elephantâs mouth. As they move forward, new molars come in at the back of their mouth.
Elephant dentition is unique. In most animals, including humans, teeth are produced from the top and bottom of the mouth. In elephants however, the teeth are developed from the back and push forward. Elephant have six sets of molars in their lifetime and as a tooth wears out through relentless grinding, another pushes forward to replace it. At birth, calves have four small developing molars which they will lose at about two years old. Each successive set of teeth will last for a longer period of time until the final set appears at about 30 years. The worn down teeth wear off into a shelf which will eventually break off and fall out.
