Hello there ,
Thanks for writing your query,
procedure disinfects the tooth by removing the infected nerve
tissue and the root canals are cleaned,shaped and filled with permanent restorative material.
has placed a root canal medicament in the access cavity probably with aloose temporary filling till the infection subsides.
This indicates the treatment is not completed , once the canals are cleaned and the tooth is devitalised you will be free from symptoms pf pain and sensitivity permanently.
Once the treatment is completed , the tooth can be restored by a post and core preparation with a prosthetic crown coverage.
i hope this helps ,
