xrays show inflamed
slight swollen at edge of tooth
but no pain

no pain, no mucus

You are still at the initial stage.
If got mucus probably need to do tooth extraction.
Since you can wait and the toothache still hasn’t started.
Go to polyclinic dental now, get referral letter to hospital dental to see dental specialist. See what he will advise you.
The waiting time for first appt is quite long but can get about 70% discount for whole procedure done. Private is damn expensive if you can’t wait.
