The wisdom tooth extraction is the most common minor oral surgery. Wisdom teeth, also known as third molars, usually appear between the ages of 17 and twenties till later in life. An extraction becomes necessary if the wisdom teeth affect other teeth during their development, if they are non-conservable or they have already become impacted. The extraction of a completely erupted wisdom tooth (i.e.; the tooth is visible in the mouth) can be performed as a simple extraction under local anaesthetia (to numb the tooth and the surrounding tissues) and needs only the use of instruments to elevate (lift) and forceps to widen the alveolar bone by slowly wiggling the tooth back and forth until it loosens enough to remove it.
