He would more likely do the RCT through the crown. If the crown is permanently cemented the dentist would have to
cutCuts and puncture wounds it off. Obviously the crown then would have to be remade. If the RCT was done through the crown a filling could be placed to salvage the crown.
If My Doctor want's to redo again is he going to bill again?(1000 dollars was already billed for rootcanal + crown)
I think he is responsible for the way he treated and he shouldn't bill further.
Please advice.
