Which restoration may be needed after a 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.

How does a filling differ from a crown after treatment?

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

What should you do while awaiting the final restoration?

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

When could a restoration problem need prompt dental care?

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

Should the tooth have a filling, onlay, crown, or post?

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