probably a good idea I am in the same predicament my tooth was very infected (different tooth) ordinary dentist kept taking out filling, packing it with antibiotic gauze and refilling it. Then sh filled allthe four root canals, filled it again and sewed it back up. Thats when I became really ill. Later the same dentist said it was badly infected pulled out the filling, then the tooth, then drilled out the root fillings and just sewed it up. I was left with no pain but have since learnt bacteria or infection could have spread anywhere and my health deteriorated again rapidly. Choose a very good dentist carefully.
