Hi, may I ansrwer your health queries right now ?  Please type your query here...I had my root canal done on the left side 4th teeth of upper jaw 7 to 8mths back, but it still had a small swelling lump above it and when pressed from outside i could feel the pain.  Now the lump n pain  had grown bigger.  the xray shows abscess between the two teeths.  a cyst is formed.  why such a thing is  developed and what would be the inexpensive treatment for it?
HiT hanks for consulting ChatDoctorRead your query, as you have abscess formation this can be deployed due to periodontal pocket formation in gum leads to periodontal abscess or this abscess can be due to infection present at root apex of tooth, don't be worried so much I will suggest you to consult dentist and go for investigations Iowa X-ray of tooth of it is due to infection in tooth you can go for re act or infection in periodontal ligament you can go for its treatment curettage. In meantime do warm saline gargle two - three times a day. Hope this will help you. Wishing you good health.
