Thanks for asking the query,
Wisdom tooth extraction
is difficult procedure and often associated with post extraction complications like pain, swelling, prolonged numbness
, difficulty in mouth opening, fever, malaise
You dont worry about the symptoms as they will subside after sometimes.
There could be a chance of some broken root peice left in the socket i would suggest you to visit the concerned Dentist
take an x-ray of the tooth if present it can be removed surgically.
Follow the post operative instructions given by the Dentist properly take lukewarm saline rinses and antiseptic mouthwash gargles twice daily.
Hope this helps out.
