I had an impacted 3rd molar tooth on the lower right jaw. This condition leads to another problem which is the formation of the 'operculum', which later cause 'pericoronitis'.
After that scenario, Dr decided to postpone my surgery to another time. Before they sent me off, they stabilised my condition first. After I was fine, suddenly Dr wanted to continue the surgery again and I said "Okay".
After that, everything went well and my 3rd molar was successfully pulled-out. Dr stitched back the incisional wound he made and I went back with painkiller prescription.
