Wisdom teeth or third molars are the last permanent teeth to form and move into the mouth and usually emerge at around 16 to 18 years of age and will be fully developed by the age of 22 or 23. With the help of radiographs (X-Rays), we can predict if there is enough room for the wisdom tooth to completely or partially erupt or become impacted. Surgery is much simpler for younger patients as bone is not as dense and roots are not yet fully developed and younger patients tend to heal more rapidly.
Oral bacteria can work their way down to the impacted wisdom teeth, frequently causing infection in the surrounding gums and bone. Cysts in the surrounding bone, resorption of adjacent teeth roots, and pressure may also push other teeth out of line, possibly creating a need for orthodontic treatment. In rare instances, if the cyst is not treated, a tumour may develop and more extensive procedures may be required for removal.
