A core buildup is a restorative dental procedure that involves the replacement of missing or damaged tooth structure with a dental material to provide a foundation for a crown.

Here’s some information about core buildup in dentistry:

Core Buildup:


The primary purpose of a core buildup is to create a stable foundation for a dental crown. This procedure is typically done when a tooth is significantly decayed, broken, or has undergone root canal therapy, leaving insufficient natural tooth structure to support a crown.


The dentist removes any decayed or damaged tooth structure and shapes the remaining tooth to receive a core buildup. A core material, often a strong and durable dental composite or amalgam, is then placed and shaped to recreate the natural form of the tooth.

Post-Root Canal Treatment:

Core buildup is commonly performed after root canal treatment, where the pulp of the tooth is removed. The buildup provides strength to the tooth, which is essential for supporting a crown, preventing fractures, and restoring normal function.

Crown Placement:

After the core buildup is in place, a crown (cap) is fabricated and cemented onto the core. The crown protects the tooth, restores its shape, and provides aesthetic appeal.

Materials Used:

The materials used for core buildup can vary and may include dental composites, amalgam, or other restorative materials. The choice depends on factors such as the tooth’s location, the extent of damage, and the dentist’s recommendation.

Strength and Durability:

Core buildup materials are chosen for their strength and durability to ensure the long-term success of the restoration. The goal is to create a stable foundation that can withstand normal biting forces.


Patients are advised to care for their restored tooth as they would for a natural tooth, with regular oral hygiene practices and routine dental check-ups.

Always consult with your dentist for personalized information and advice based on your specific dental needs and conditions.
