My dentist in Chestnut Hill recommended an endodontist, Dr. Allison Abbot, whose office is on 2050 Butler Pike, Ste. 300 (610-834-7770). Warning: it can take a while to get an appt. I waited too long (because the pain kept coming and going) and wound up having an emergency root canal with my dentist. Not a good idea. Therefore, I don't have personal experience with Dr. Abbot. I can't comment on the insurances. I would find a dentist I liked and see what insurances he/she accepted and how much coverage you have. I liked Delta Dental the best but now have Met Life high option, which isn't great because our dentists are all out of network.
