Hi,\n \nI have a crown on my upper Molar right hand side. I had root canal on it. I now have found out I have a abscess in there too. I have a lump in my jaw line. When I discovered the lump my dentist still wanted to crown it. It has now been just under 1 year with this lump. I have no pain. My dentist said it wasn't an Abscess but now she saying it is. I have had no antibiotics. She said my only options are have a specialist try and do the root canal treatment again which will cost around £600 or have it extracted. I don't want to loose the tooth but im not sure the re-root canal is 100% fix. I have never had an extraction before so don't know what to expect if I do go down that route. Surely eating without a Molar is going to be an issue? not to mention the actual procedure itself. I do have a dental fear so I am scared, I just don't know what to do as an extraction I guess is the worse possible outcome. Can I just leave it? im not in pain, the only reason I know I have an abscess is because of the lump I can feel with my finger. I can chew as normal.
