Hello...i had an apicoectomy 2 weeks ago.  I have a white bump over my tooth.  I researched online and they said it was a fistula.  Is it common for this to happen?  Went back to the dentist and put me on anitbiotics.  Would that clear it up or it is indicating a problem?  I have no pain,  Thanks!
Thanks for your query, I have gone through your query. The bump over the tooth can be an abscess or a pus discharging sinus tract secondary to tooth or gum infection. The antibiotics alone will not solve the problem. You need to get the cause treated, that is got the tooth treated with root canal treatment. If it is a gum infection, you can get the teeth cleaned. So consult an oral physician and get it evaluated, and you need to take a radiograph to confirm the diagnosis. I hope my answer will help you, take care.
