Should root canal be finished if root is calcified?

Calcified canals: The answer to that would best be discussed with an endodontist and general dentist in combination familiar with the tooth, bone support, periodontal condition, bite, adjacent teeth, occlusion, teatment alternatives in addition to other factors. We can't give you a blanket yes or no answer. In generally boils down to prognosis, risk assessment and a subjective value judgment by you ; your dentist.

Ideally: If there is an infection, then the root canal must be finished. If there is no infection, then it is a bit more complicated. If the tooth needs a major restoration like a crown, then ideally the root canal should be finished. If no treatment is planned for the tooth, then it may be okay to leave it unfinished for now, but it needs to be monitored closely in case it does develop an infection.

Depends: Sometimes a natural root canl can be done by the body, where a tooth will calcify inwardly in the canal and actually create it's own root canal treatment. If infection is present, a minor surgical approach may be needed- an apicoectomy, which cleans out the root area directly.

Root Canal: The answer is yes, in an ideal world. The reality is that if a canal/canals in a tooth are extremely calcified, they may not be able to be accessed without drilling so deep into the tooth that the tooth is at risk to being non restorable. Your dentist can advise you on this. They should give you the risks/benefits of chasing a calcified can versus non treatment.

See an endodontist: Negotiation of calcified canals is often a very difficult procedure, but an endodntist, an adequate technique with as small instruments as possible and a microscope may be a key to success. See an endodontist.
