Hello Dear
Thanks for your query, I will be most happy if I could help you out so no need to worry much.
I have thoroughly gone through your query and your mentioned signs and symptoms suggest that you might be suffering from
dental abscess or say tooth abcess. And the lump bneath that tooth may be the abcess filled
sinus tract through which pus comes out.
It is possible that your filled tooth developed caries (cavity) bneath the filling material and infected the pulp of the tooth which gradually caused the abscess.
• I will advice you to get an appointment with a
dentist as early as possible so that he/she can do thorough clinical examination and will take the radiograph (
X ray) to confirm the diagnosis and start the needful treatment (Procedure+Medication).
• In your case, it is very much possible that
Root Canal Treatment of the offending tooth will solve out the problem.
Hope this will help you. If there is any more query or question regarding this in your mind, you are free to ask me any time.
Take Care
Regards
