HI my name is Justin. I have been dealing with sever pain for a month or 2 in a tooth that had a root canal about 4 years ago and at that time I had some pain they attributed to being to high so it was ground and antibiotics injected. \n\nCurrently I t is used as an anchor for my bridge and I had a crown installed about 4 months ago the last 2 I have had an abses and pain the last month its been sever. I fear that it was becoming septic but it turned out I had gotten shingles, About 2 weeks ago I had a dentist look so they cleaned it out drilling through the crown and putting a temporary filling, it fell out after a day I returned the next and had it replaced. The next day the pain radiated from the center of th bottom front to my ear any little heat, cold or air hurts terribly.\n\nWill I need to remove this tooth? If so my bridge will be no good I guess. \n\nThanks for any advice you may give.
