The third set falls out at 9–15 years of age, and set four lasts until 18–28 years of age.

This can last from a day to four months.  At Hluhluwe–Umfolozi Game Reserve, South Africa, introduced young orphan elephants went on a killing spree that claimed the lives of 36 rhinos during the 1990s, but ended with the introduction of older males. By contrast, Japan and Hong Kong, which were also part of the industry, were able to adapt and were not badly affected. Unlike most mammals, which grow baby teeth and then replace them with a single permanent set of adult teeth, elephants are polyphyodonts that have cycles of tooth rotation throughout their lives. Other threats to wild elephants include habitat destruction and conflicts with local people. Male Asian elephants are usually about 261–289 cm (8 ft 7 in–9 ft 6 in) tall at the shoulder and 3.5–4.6 t (3.9–5.1 short tons) whereas females are 228–252 cm (7 ft 6 in–8 ft 3 in) tall at the shoulder and 2.3–3.1 t (2.5–3.4 short tons).
