Do i need a post and crown after root canal
A post retains a core when little tooth remains, while a crown may protect a root-treated tooth from biting forces.
The short answer
A post is used only when remaining tooth structure cannot retain the core; a crown or another cuspal restoration is chosen when the tooth needs protection from biting forces.
Why might a root-treated tooth need extra support?
Root canal treatment removes pulp from inside the tooth. The decision depends on remaining walls, cracks, tooth position, bite, and how much sound enamel and dentine remain.
What restoration should you arrange after treatment?
The dentist examines the tooth and may use a bonded core, onlay, or crown. A post is placed inside a prepared canal only when the core needs retention.
When should you seek care for problems after treatment?
Return promptly for pain on biting, a loose or broken temporary filling, or gum swelling near the treated tooth.
What should you ask about your tooth restoration?
Ask how much tooth remains, whether a post adds retention, and which final restoration will seal and protect the tooth.
