Hi, About a year ago, I suddenly developed shooting pains in the front of my face, above my upper front teeth. I went to the dentist, who x-rayed me, and said I had an abscess, above my left upper 1 tooth. He did root canal treatment, but could not find anything, the pain did not go away, and after several root canals, he referred me to a consultant for an apicectomy. When the operation was done, as he drilled through the bone, he said there was lots of pus to drain away.
