Cast Post and Core
Cast Post and Core
A restorative dental procedure used to rebuild and strengthen a tooth that has undergone root canal treatment and has lost a significant portion of its structure. It provides a solid foundation for placing a crown, restoring both function and appearance.
During the procedure, a post is custom-made (cast) to fit securely into the cleaned root canal of the treated tooth. The “core” is then built around the post to replace the missing tooth structure and support the crown. This process ensures the restoration is stable, durable, and capable of withstanding normal chewing forces.
When Do You Need This Procedure
You may need a Cast Post and Core if you have a tooth that has undergone root canal treatment and has lost a significant portion of its structure due to decay or damage. It is also recommended when a tooth is too weak to support a crown on its own. By reinforcing the internal structure, the post and core help prevent tooth fracture and extend the life of your restoration.
Important to Know About Cast Post and Core
The Cast Post and Core procedure plays a crucial role in restoring teeth that have lost most of their structure after root canal treatment. It provides the necessary support for a crown, ensuring the tooth remains strong and functional for many years.
It’s important to know that this procedure is not a standalone restoration — it serves as the foundation for a dental crown, which protects the rebuilt tooth from further damage. Regular dental visits and good oral hygiene are essential to maintain the integrity of both the post and crown.
With proper care, a Cast Post and Core can help preserve your natural tooth and prevent the need for extraction or more complex treatments in the future.
Frequently Asked Question
Is a Cast Post and Core procedure painful?
No. The procedure is performed under local anesthesia, ensuring you remain comfortable and pain-free throughout. Since it’s usually done after a root canal, the tooth is already non-vital (no nerve), so you’ll feel minimal to no discomfort during the process.
How long does a Cast Post and Core last?
With proper oral hygiene and regular dental check-ups, a Cast Post and Core can last 10 years or more. Its longevity depends on maintaining good oral health, avoiding excessive pressure on the tooth, and ensuring that the overlying crown remains intact and well-fitted.
