hello there ,
Extraction of the tooth is done along with drainage of the periodontal abscess
involved with the tooth.
Once the abscess is drained the area is curretted to remove all the irritants and the socket is compressed.
any remnant infection in the socket may lead to spread of abscess in the periapical and submandibular area.
you need to get an x ray done the affected area to confirm the presence of infection, approach a dentist
for the treatment.
i would suggest you to go for symptomatic treatment at home like gargling with lukewarm saline water or antiseptic mouthwash like chlorhexidine
continue with the course of antibiotic Augmentin
625mg along with analgesics like aceclofenac
two times daily for 3 to 5 days .
i hope this helps,
