‘Wisdom teeth’ is the name given to the third and last group of molars to erupt. They are meant to appear between the ages of 17 and 21, however the timeline differs from person to person.
Wisdom teeth may have enough room to erupt and may not require any additional treatment. Though, more often than not, wisdom teeth become impacted or erupt in a strange angle or location.
The extraction of impacted wisdom teeth may be recommended because of the problems that may cause, including infection, decay of adjacent teeth, gum disease, cysts and tumors.
Sometimes, wisdom teeth that have already erupted may also require removal if they are badly decayed, interfering with your bite, nonfunctional, involved with or at risk of gum disease, or causing problems with adjacent teeth or restorations.
