Post Crowns
Post crowns are employed when a tooth has undergone root canal treatment. The compromised tooth crown is removed to the gum line, and the dentist creates a dual-ended “post” to fit within the root canal. One end of the post is cemented into the root canal, while the other end securely holds the crown in place. This post can be either prefabricated stainless steel or custom.
Reasons for Needing a Post Crown
- Tooth has undergone root canal treatment and most of the crown portion is lost.
- Insufficient natural tooth left to hold a normal crown.
- Tooth needs extra support to handle chewing forces.
- Repairing a tooth damaged in an accident.
- Securing a bridge or denture in place.
Advantages of Post Crowns
Post crowns could save teeth that otherwise would need extraction. They provide strength and stability for the crown and restore chewing ability and appearance.
In simple terms, a normal crown is placed over a tooth that still has enough structure. A post crown is supported by a post inside the root when the tooth is too weak on its own.
