filling was used to cover up the hole left from the root canal. is that the normal procedure or should a new crown be placed?

Engineering: A post may be placed in the tooth to engineer the maintenance of strength, and then a core filling material is constructed on top. This can give adequate strength to have a crown placed on this tooth for the longer term usefulness.

Tooth build up: From your question it seems like you already have a crown and then they had to do a root canal through the crown. In that situation, just filling the hole by doing a build up is enough provided the existing crown is in good shape. However if there is no existing crown on that tooth and the root canal is done , then you need a crown on the tooth for further protection after the root canal

Even if patient has a crown it is dependent upon the size of the endodontic access aperature, if it is quite large it can reduce the viability of the crown structurally. Have dentist look at it and see if a new crown is needed. If it was done on a virgin tooth (no metal/ceramic) crown, then a post and core and crown should be fabricated to give longest term structural integrity to the tooth.

Crown & root canal: It depends who and when the crown was made. If dentist 'a' does a crown (ie; all zerconia or all gold) well and than the patient has a root canal shortly after, through a small opening than its acceptable to close the hole with a permanent filling and not replace the crown. Ask your dentist whats correct for your tooth.
