Wisdom teeth as commonly known as are the third molars of human dentition.
They are called so, as they erupt at the age of 18-25 at which it is assumed that an individual becomes wiser.
These teeth erupt at an age, when rests of the 28 permanent teeth are well settled in the dentition. Due to the evolution the human jaws are getting smaller and hence there will not be sufficient space left for the erupting third molars. So they either get locked in the bone leading to impaction or they erupt at wrong angulation. Either of these can create problems to adjacent teeth and the surrounding soft tissues.
