An average elephant has two tusks, which are technically extended incisors, and then four molars with one molar conforming to each half of the upper and lower jaw respectively for a total of six teeth. Elephants wear through their molars over time and go through an average of six sets of four over the courses of their lives

The total number of teeth an elephant has is 24, six in each half jaw. No more than two of the six teeth are in wear at the same time in each side of a jaw (the only exception is in young elephants which may use three.) Teeth grow from the back of the jaw and follow a linear pathway of movement forwards as the preceding tooth is progressively worn down in the front. Each tooth drops out as it reaches the front of the elephant's jaw.

As an elephant gets older one of the most limiting factors in its ability to live a longer life is the teeth. Once the last molar the elephant has wears out it is incapable of chewing its food properly and either death from starvation or malnutrition will occur. Interestingly, about 10% of the older aged elephants will have an additional seventh molar, but it is never as developed as the others.

The tusks are actually upper incisors, not canines. They are the only incisors the elephant has. Tusks are fundamentally no different than ordinary teeth.
