Why do wisdom teeth have to be removed in the first place? Here is a quick summary of the reasons why wisdom teeth have to be removed and I also touched upon the point how NICOs form from the empty space of the wisdom tooth.
The picture shows the case of my sister, a very special case, where the wisdom tooth is placed in the sinus area.
We need to ask the question as to why wisdom teeth play such an important role in western industrialised countries. They are often displaced transversely in the jaw, have insufficient room to erupt and therefore re- quire surgical removal. An error of nature?
