Hoping someone can help, I had a root canal done a few months ago, recently started having the worst pain ever went to the dentist he took xrays and seems either there is some root left behind or a it seems a file have broken off in off canals which by the look of the xrays seems to be the case due to how straight it is and might be trAppin some neres. I have been given two options and not sure what to do, either see a specialist and see if the can remove it or get the tooth extracted? Can any help?
