There are 32 permanent teeth, out of which four wisdom teeth begin to grow a little late.
Now, when our ancient ancestors used to eat plant material and raw meat, they required big strong jaws and wisdom teeth to chew their food.
However, as they learned to cook food, they no longer required those big jaws. Hence, through evolution, the jaws started to get smaller and smaller. But the wisdom teeth did not disappear through evolution. They still exist. But since they appear a little late, the remaining teeth usually take up the available space in the small jaw, leaving no room for the wisdom teeth. Hence, they begin to grow at odd angles and push other teeth causing pain, swelling, tooth decay and even infection. Hence, in such cases, wisdom teeth can prove to be harmful and not useful.
