Root canal: You will do the root canal first and then restore the tooth, usually with a crown.

The tooth will need a root canal IF the pulp does not respond normally to testing. I that case root canal first and the cavity is taken out during the procedure and a restoration is placed. If the pulp responds normally, or within normal limits, just have the cavity repaired and the tooth retested in 4-6 weeks. You may not need a root canal treatment.

Simultaneous: Endodontist will remove all disease tooth material, then seal the root canals. Your general dentist will then cap the tooth to seal and support the crown of the tooth. It's a collaborative effort.
