The wisdom tooth is the last tooth to emerge and it definitely has nothing to do with the perfection of human intellect. In fact, the wisdom tooth is the last and third set of molar teeth. Teeth grow and develop like other parts of the human body. The tooth must also go through stages to reach the final stage, which means the completion of the growth of the last tooth. Not removing wisdom teeth has complications; especially if it has decay or due to the lack of access to a toothbrush, bacteria and food can accumulate in it and cause infection.In this book, an attempt has been made to provide complete information about the types of wisdom teeth, surgical methods, drugs used, side effects and benefits of surgery, and other information. The audience of this book is dental students, dentists, residents and maxillofacial surgeons as well as ordinary people. In the existing books, a chapter has been dedicated to wisdom teeth, which information is incomplete and has not examined wisdom teeth and surgical methods from all aspects.
