How can a wisdom tooth be removed if it is shattered?

[MPowerMark]

One of my lower wisdom teeth cracked and broke into two last week with one chunk comming out of my mouth. Problem is i have a dentist appointment later this afternoon but the other part of the tooth is really loose and feels like it is about to fall out. What will a dentist do? to remove a wisdom tooth surely you need to remove the root also? but how can this be done if there is no tooth to grip onto? If a dentist tugs on what is left of my wisdom tooh it's easily going to come out. Would a dentist plug the hole so the nerve isn't exposed or could i potentially be in for abit of an awkward and painful operation/procedure?
