The root canal
has been done 3 years back and is paining now does not means that the only solution is extraction. we can re do the root canal procedure. In this we remove all the root canal filling material and then again prepare the canals, clean it with medicament, disinfect it and the re fill it with sterile material in the canals till apex. after that we secure it with the crown over it.
The best person who is expert in Re- RCT are the endodontics, if your dentist
is not ready to do it, I suggest you should take a second opinion
and check it with endodontics about it.
In many cases the re-treatment cannot be done, that endodontics will judge.
