Post & Core Build-up
Strengthen severely damaged teeth after a root canal. Our custom post and core build-ups provide a solid foundation for your permanent crown.
Welcome to our guide on Post & Core Restorations!
After a root canal or severe decay, a tooth often loses a significant amount of its natural structure. A post and core build-up is a critical restorative procedure used to strengthen the tooth before placing a final crown.
What is a Post and Core?
A 'post' is a small, strong rod inserted deep into the cleaned root canal. The 'core' is a custom-shaped composite material built around the top of the post. Together, they create a solid, artificial foundation (like the rebar inside a concrete pillar) that securely anchors your final dental crown.

Benefits of Post & Core Build-ups
Ensuring your restored tooth lasts a lifetime.
Structural Integrity
Provides essential internal support for teeth that have lost more than 50% of their natural crown structure.
Secure Crown Anchor
Creates a stable core that prevents your final porcelain crown from breaking or falling off during heavy chewing.
Biocompatible Materials
We use modern fiber posts or cast-metal posts that flex naturally with your tooth, reducing the risk of root fractures.
Save the Tooth
Allows us to save teeth that are broken down to the gumline, avoiding the need for an extraction and an implant.
The Build-up Process
Canal Preparation
Following a successful root canal, a small amount of the filling material is removed to create a precise space for the post.
Post Insertion
A custom-sized post (often made of flexible glass fiber or cast metal) is securely bonded deep into the root canal.
Core Creation
Strong composite resin is applied around the top of the post and cured with a special light to build up the 'core' of the tooth.
Crown Preparation
The new solid core is shaped, an impression is taken, and a permanent, custom-made crown is placed over it.
Aftercare for Your Restoration
Once the final crown is placed over the post and core, treat it exactly like a natural tooth. Brush twice daily, floss regularly, and avoid chewing ice or hard candies that could crack the porcelain crown.

The cost of a post and core build-up is separate from the root canal and the final crown. It depends on the type of post used (pre-fabricated fiber vs. custom cast metal). Our team will provide a transparent estimate.
