I have been fighting with a chronic fistula for over 3 yrs now. It began on the outside of tooth #3. Which had had 2 root canals on it. They finally decided to pull the tooth because of the chronic infection. It would swell up the whole side of my face. They would put me on an antibiotic and it would go away for a while and then come back. So we just pulled it. After tooth was pulled we decided to do an implant. So 3 or 4 months after extraction the oral surgeon did a bone graft. waited for 3 months and put the implant in. Even during this time the fistula would fill up and i would pop it and so on. After the implant went in I did another round of antibiotic (amox). After a couple of weeks my face swelled up again. The oral surgeon said the implant failed and would need to come out. He also discovered the #4 tooth had a a large crack in it. So he removed both the implant and bone graft. Then removed the #4 tooth. Again waiting to heal several months. In the mean time the fistula continues. I waited for 4 months and went back to oral surgeon. He again placed the implant in. This time did not need to do the bone graft. I explained to him that it will indeed infect and swell up but he did not put me on an antibiotic. 1 week later face is swollen and infection returns. He puts me on an antibiotic (amox) and said to just give it some time.
About a month later fistula fills up again and I decide to get a second opinion. The new oral surgeon did an xray and said that the implant was failing again and I should have it removed. He put me on Clyndamicyn. And now today (1 month later) fistula is filling up again and is aching.
So with all that being said...What the heck is causing this fistula? There are no teeth back there anymore. Do I have the implant removed again? HELP!!!
