Filling in crown after root canal

A root-canal-treated tooth may need a filling, core, onlay, or crown depending on remaining structure, cracks, tooth type, and chewing forces.

Root canal treatment seals cleaned canals, while a filling replaces a limited defect, a core rebuilds shape, and a crown covers a prepared tooth.

Avoid hard chewing on a temporary restoration and return for the definitive restoration; the dentist assesses tooth walls, cracks, bite, and retention.

Seek care for pain on biting, a loose or cracked restoration, swelling, bad taste, or a lost temporary filling.

Ask whether a bonded filling, onlay, or crown best protects the remaining tooth and whether a post is needed for retention.
