Thanks for asking the query,
I would like to tell you that surgical extraction of tooth is not a simple extraction , it is somewhat complicated surgical procedure and there are many post extraction effects like pain , swelling , prolonged numbness
, fever , malaise
is due to the use of antibiotics and analgesic
prescribed to you .
swollen lymph nodes can be because of tooth infection.
A complete extraction wound healing takes about 3 months but pain go off completely in 3-5 days . There could be a chance of some broken root piece or a dry socket to rule out this you need to visit to your Dentist
and take an x-ray .
Take complete rest start with amoxiclav
625 twice , tab zerodol twice also take multivitamin
and antaacid tab rabeprozole 20 mg all this for 5 days .
Take lukewarm saline gargles , antiseptic mouthwash gargles twice daily.
Hope this helps out.
