Thanks for asking the query,
Wisdom tooth extraction
is not a simple procedure and often associated with post operative complications like pain, swelling, prolonged numbness
, fever , malaise.
Nausea and vomitting is due to the use of antibiotics and analgesics prescribed to you , i would suggest you to stop the medications and take complete rest, you can take antiemetic drug .
You dont worry about the symptoms as they will subside after sometimes.
Follow the post operative instructions given by the Dentist
Maintain a good oral hygiene
Use antiseptic mouthwash rinses and lukewarm saline gargles.
Hope this helps out.
