Thanks for asking the query,
According to your clinical symptoms i suspect that you have developed an Periodontal abscess
, this can be due to poor oral hygiene
, plague and calculus deposition, hormonal
imbalance, use of certain medications.
I would suggest you to go for professional scaling and polishing, curettage.
Take a complete course of antibiotics and analgesic
If not tooth related the growth can be excised surgically.
Apply mucopain topically over the affected area.
Maintain a good oral hygiene, use antiseptic mouthwash gargles twice daily.
Hope this helps out.
