Q. Hi I have had an abcess on one of my front teeth for about 6 weeks. I had 3 courses of antibiotics and have now started having root treatment with my own dentist, there is also still a lump over the top of it but it has gone considerably smaller since the root treatment started. At my last visit she recommended that I see a specialist to have this treatment done. Does this mean that it is really bad and I could lose my tooth. Thanks
