How the treatment goes
A tooth extraction starts with local anaesthetic, after which the oral surgeon loosens the tooth from the bone and removes it. A simple extraction takes 20 to 30 minutes. An impacted wisdom tooth, one that stays in the bone or under the gum, needs a small incision, sometimes sectioning the tooth, and 45 to 60 minutes. For lower wisdom teeth, the surgeon first checks on the 3D CT scan how close the nerve is.
