Wisdom teeth are the most posterior molars. Seen from the centre, it is the 8th tooth on the left and right of the upper and lower jaw.
Generally speaking, every human being has four wisdom teeth. The name “wisdom teeth” comes from the fact that they only erupt in adulthood, at an age where people are presumably “wiser”. In Latin, they are called “dentes intellectus”. In many cases, wisdom teeth have to be extracted because there is a discrepancy between the size of the jaw and the number of teeth. These disproportions cause the wisdom teeth not to erupt or to erupt only partially (partially impacted). Partially impacted teeth often lead to inflammation.
