Wisdom teeth, or third molars, are the last teeth to develop and appear in your mouth. They come in between the ages of 17 and 25, a time of life that has been called the “Age of Wisdom.”
What is an Impacted Tooth?
When a tooth is unable to fully enter the mouth, it is said to be “impacted.” In general, impacted teeth are unable to break through the gums because there is not enough room. Nine out of ten people have at least one impacted wisdom tooth.
How serious is an impacted wisdom tooth?
If left in the mouth, impacted wisdom teeth may damage neighboring teeth, or become infected. Because the third molar area of the mouth is difficult to clean, it is a site that invites the bacteria that leads to gum disease. Furthermore oral bacteria may travel from your mouth through the bloodstream, where it may lead to possible systemic infections and illnesses that affect the heart, kidneys and other organs.
Research has shown that once periodontal disease is established in the third molar areas, the problem is persistent and progressive, but may improve following extraction of the teeth.
In some cases a fluid-filled cyst or tumor may form around the base of the untreated wisdom tooth. As the cyst grows it may lead to more serious problems as it hollows out the jaw and damages surrounding nerves, teeth and other structures.
