Post & Core
Post and core treatment is a restorative procedure performed after successful root canal therapy to rebuild and strengthen a tooth that has been extensively damaged or weakened. This procedure is essential when there is insufficient natural tooth structure remaining to support a final restoration such as a crown.
Post and core systems can be made from various materials, including fiber-reinforced composites, metal alloys, or ceramic, each selected based on the clinical requirements and aesthetic considerations. Fiber posts are commonly preferred today due to their elasticity, which closely resembles natural dentin and reduces the risk of root fracture.
Modern advancements in adhesive dentistry and digital techniques have significantly improved the precision and longevity of post and core restorations. When combined with a well-fitted crown, this treatment restores function, enhances aesthetics, and prolongs the lifespan of the treated tooth.
Post and Core
What is a Post and Core?
Core: A filling material (composite or other dental material) that rebuilds the main body of the tooth.
Post: A rod (usually metal or fiber-reinforced) inserted into the root canal to help anchor the core in place, especially when there’s not enough tooth structure left above the gumline.
It’s like creating a foundation and support pillar for a crown on a tooth that’s otherwise too weak or broken down.
When is a Post and Core Required?
- You’ve had a root canal, and most of the natural tooth is missing or destroyed.
- There’s not enough tooth structure to hold a crown on its own.
- The remaining tooth is too weak to support normal chewing forces.
Benefits of Post and Core
- Strengthens the tooth: Reinforces a weakened or broken tooth, making it strong enough to hold a crown.
- Improves crown retention: Provides solid support for the crown to stay in place long-term.
- Preserves the tooth: Allows a badly damaged tooth to be saved and restored, instead of being extracted.
- Improves function and appearance: Restores the tooth’s ability to chew and bite, while also improving aesthetics.
- Cost-effective alternative to extraction: Helps extend the life of your natural tooth and avoid implants or bridges.

To anchor a crown when little natural tooth remains.
Fiber-reinforced, metal, or ceramic posts
No, it’s done under local anesthesia.
Usually one sitting (30–60 minutes).
10–15 years with regular check-ups.
