Wisdom teeth are the teeth farthest back in the dental arcades and sometimes refuse to emerge. To benefit from complete dentition, the back of the jaw should have sufficient growth. However, since most people’s jaws do not allow the required space, the wisdom teeth cannot erupt. To summarize, if the growth of the jaw is inadequate, the wisdom teeth will remain impacted. If they take too long to erupt, they are very likely to be semi-impacted (they only superficially erupt through the gum). Most dental professionals consider that it is wise to extract wisdom teeth that cause complications. Pain, an infection, or crowding of neighbouring teeth can all be avoided by extraction.
