Thanks for asking the query,
I would like to tell you that wisdom tooth extraction
is not a simple extraction and it is often associated with post operative complications like pain, swelling, fever, malaise, difficulty in mouth opening, swallowing.
You dont worry about the symptoms as it will subside after sometime.
Difficulty in swallowing is due to swelling in the uvula, normally after anesthesia
swelling and numbness
lasts for about 24 hours, visit to the concerned Oral and Maxillofacial Surgeon if it last for more than 24 hours.
Follow the post operative instructions given by the Dentist
Take complete rest, take complete course of antibiotics and analgesics.
Meanwhile at home go for symptomatic treatment like lukewarm saline gargles , antiseptic mouth rinses
Hope this helps out.
