What does “Core build-up” mean?
A core build-up replaces missing structure in the severely damaged crown portion of a tooth with material to create a shape that supports the final prosthesis. Together with the remaining natural tooth, it provides a foundation for a crown or another restoration.
Why is the shape built up first?
When much of the crown is lost to decay or fracture, there may be insufficient shape and support for a crown. The necessary areas are replaced while making as much use as possible of remaining healthy tissue.
Is a post also needed?
In a root canal-treated tooth, a post within the canal may be considered if the remaining coronal tissue cannot retain the core adequately. A core build-up does not mean every tooth needs a post.
Is treatment finished after the core is built?
A core used as one stage of the final restoration is part of the plan for a crown or another restoration. Coronal sealing and protection against chewing forces still need to be completed.
Frequently Asked Questions
Are a core and a crown the same?
A core replaces the missing foundation, while a crown is a prosthesis covering the prepared coronal portion of a tooth. Their roles differ.
Does core material fully replace natural tooth structure?
Even after the shape is restored, the amount and distribution of remaining natural tooth structure matter. More material alone does not provide adequate support from the root or tooth walls.
