Thanks for asking the query,
Pus discharge from the gums can be because of bacterial infections of the gums and surrounding tissues leading to abscess
formation, this can also be because of tooth infection . Drainage
of pus into the oral cavity leads to nausea, vomitting , halitosis
and stomach infection.
It is aggravated by poor oral hygiene plague and calculus deposition , systemic conditions like diabetes
disorders, use of certain medications.
Visit to the Dentist
and get a checkup done.
Take an OPG x-ray.
Get complete mouth scaling and polishing done .
Use saline water gargles 3-4 times a day it will give a soothing effect .
oral ointment topically over the affected area.
Hope this helps out.
