Just my humble experience - I had the failed root canal from hell once and learned some things. The new Dentist referred me to an Endontist. When they say specialized it is meaningful. An Endodontist uses an anaesthetic that is way different - mild after effect smooth all the way. They use a different x-ray system that gets the critical angles to see twisted and hidden roots. It was an interesting experience and actually cost me less than the Dentist that did the first job. I learned that molars are tricky and that it is easy to miss a hidden root in one. While I cannot refer it was a very positive dental experience that made me a believer in the Endodontist.
