Anchor a secure dental crown to a root canal-treated tooth that has lost too much natural structure to hold a standard restoration alone.
A post and core restoration is a specialized procedure used to rebuild teeth that are severely weakened after root canal therapy. By anchoring a strong support post deep inside the root canal space and building a composite core around it, we establish a secure foundation for a final crown. We help you address:
Feature | Post and Core Restoration | Standard Core Build-Up |
|---|---|---|
Primary Indication | Severely hollowed-out tooth following root canal therapy | Tooth with enough remaining internal structure to bond composite directly |
Anchoring Method | Uses a specialized post inserted directly into the root canal space | Relies on direct bonding to remaining healthy enamel and dentin |
Structural Purpose | Provides deep retention for a crown when natural tooth roots carry the load | Rebuilds surface height and shape without entering the root canal |
We verify that your previous root canal treatment is completely stable and healthy before planning your restorative post.
We carefully prepare a secure channel within the root canal and place a high-strength support post.
We build up durable composite material around the post to recreate the internal shape and height of your tooth.
We shape your newly reinforced core and take digital impressions so a laboratory can craft your permanent crown.
When Dr. Mohammad Hammoud restores a tooth following root canal therapy, he ensures the entire root structure is utilized effectively. Placing a dental crown on a root canal-treated tooth without a proper post and core foundation often leads to structural failure because the remaining walls are too thin. By anchoring a post deep into the root, we distribute chewing forces evenly and protect your tooth from fracturing.
If a root canal-treated tooth has lost most of its natural walls, a post provides the deep internal anchorage required to keep a dental crown from dislodging.
No. Because the tooth has already undergone root canal therapy, the nerve is gone, and the procedure is completed comfortably under local anesthesia.
We typically use modern fiber-reinforced composite posts or high-strength metal posts depending on your specific structural needs and bite forces.
Most can, but we evaluate your remaining root health, bone support, and gum status first to ensure the tooth can be predictably saved.
