Upper molar with full gold crown .
Suspected cracked root .
Suspected calcification of nerve .
Dental hospital recommend that my dentist removes gold crown and checks if root is cracked .
My dentist says this is a no go as removal will break tooth and he is saying root filling through crown and then "we'll see " if root is cracked .
Also saying that it's possible nerve is calcified ( hosp didn't mention this ) and that this may prevent root filling .
We didn't discuss removal but I'm wondering if I shouldn't ask for that ...
