That's a fancy word for surgical root canal that goes in through the gum and tip of the root
, rather than drilled from the tooth
. It depends on how much of an abscess
there is, where it's originating from, etc. But the dentist was right to refer you to an endodontist. Root canals CAN fail, and it isn't necessarily the result of dentist error. At this point it's much better to visit a specialist than try to get retreatment from the original dentist, IMO.
