Thanks for asking the query,
According to your clinical history i suspect that you had a severely decayed tooth, which was extracted
by the Dentist
, some remanants of the tooth or root pieces can be left in the socket which was not curetted, giving rise to pus formation and foul odour.
Visit to your Dentist and get proper curretage and flushing
of the area using an antiseptic solution.
Follow the post extraction instructions carefully.
Take complete course of antibiotics and analgesics.
Use antiseptic mouthwash rinses twice daily.
Hope this helps out.
