Wisdom teeth, also Known as the “third molars”, are as important as other teeth, but more prone to problems during their eruption (breaking through the gum tissue). Since wisdom teeth use to erupt usually between the ages of 17 and 21 — there often is little space left in the mouth.
As a result, they may erupt in sideways, only partially, or become trapped (impacted) which leads to pain, infection, and gum line and facial swelling. When any of these conditions arise, your dentist may determine that extraction is necessary.
Extraction is defined as a process of removal of a teeth under local anesthesia (numbing) which includes removal of grossly decayed teeth with infection that cannot be healed , teeth without decay teeth with gum disease that cannot be reversed, and root stumps without crown structure.
Impacted teeth are those teeth that remain un-erupted, buried in the bone or slightly submerged than the neighboring teeth due to lack of space for eruption or delay in falling of the milk tooth.
The most commonly impacted teeth are the Third molars or wisdom teeth.
The third molars are the last teeth to erupt in our oral cavity. It is most commonly called as the wisdom teeth.
Most commonly the third molars erupt in an abnormal position which often leads to as a impacted teeth.
Otherwise the inadequate space in the oral cavity can also lead the third molars as an impacted teeth.
WHY EXTRACTION OF THIRD MOLARS ARE NECESSARY:
When a third molar erupts in a wayward direction, it may neither aid in chewing or in proper cleaning of the teeth. Food getting lodged between the third and second molar due to the improper positioning may cause the teeth to decay , leading to loss of both teeth.
The impacted teeth may form cysts when they are locked within the bone. Such cysts silently erode the jaw bone without showing any symptoms. Therefore it is necessary to check these impacted teeth periodically with regular xrays .
Inadequate space in the oral cavity leads to extraction of third molars so that adequate space can be given to the other teeth.
The abnormal position of the third molars can cause many problems like caries in the adjacent tooth, pressure on the next tooth that can cause crowding in the front teeth. sometimes the teeth can erupt near or on the mandibular nerve causing severe pain. in these cases extraction of third molars are required.
The other indication for extraction of third molar is for orthodontic treatment.
Most often, dentists recommend removal of these impacted teeth due to the potential problems that it can cause later .
REMOVAL OF THIRD MOLARS:
For a fully erupted third molar a normal extraction is done but for an impacted teeth a minor surgical procedure is needed which is minimally invasive. it can also be done in conscious sedation or even general anesthesia.
