Third molars, also called wisdom teeth, are the last set of permanent teeth to erupt in a person’s mouth and are the ones least needed. While the removal of wisdom teeth is the most well-known type of oral surgery, there are many reasons why oral surgery may be required.
A wisdom tooth or third molar is one of the three molars per quadrant of the human dentition. It is the most posterior of the three. Wisdom teeth generally erupt between the ages of 17 and 25. Most adults have four wisdom teeth, one in each of the four quadrants, but it is possible to have fewer or more, in which case the extras are called supernumerary teeth. Wisdom teeth commonly affect other teeth as they develop, becoming impacted. They are often extracted when or even before this occurs.
Oral surgery specializes in treating many diseases, injuries and defects in the jaws, the hard and soft tissues of the oral (mouth) and maxillofacial (jaws and face) region. It is an internationally recognized surgical specialty. In countries such as the UK, and most of Europe, it is recognized as both a specialty of medicine and dentistry, and a dual degree in medicine and dentistry is compulsory. In other countries including the United States, India, Canada, Brazil, New Zealand, Australia, Sweden, and Israel.
