In your area Gwalior there are many quakes who can't perform specific dental treatments such as RCT. So be careful. Now, considering your dentist
is reputed one, let him perform whatever is needed in your case because he can visualize and know the problem better. If required, a re -RCT can be done. Why I am saying this because RCT itself can cure tooth related problem, now what operation is required to take out germs, God knows. Just be careful.
