whatever you decide to do you must get rid of all that bacteria and infection it is the most important thing. The infection in my root canal filled tooth and the one next to it have travelled around my body and i am now in a mess. I was actually told by a dentist who has since looked at the site that it was so bad i should have had it removed by a surgeon in hospital and cleaned extensively. He said people dont realise how damaging this stuff is and can actully by itself cause heart conditions. What the hell have they done to us all and we have to pay the cost in being ill and financially strained. It is one huge scandal.
