Everything you need to know about Post & Core
Why is post and core needed?
A post and core procedure may be needed sometimes before placing a crown.
A great deal of crown/cap stability depends on the remaining natural tooth structure that extends into its interior. If very little sound tooth structure occupies this space, the crown will be easily dislodged. The core build up is rebuilding the tooth closer to its original dimensions so that the overlying crown is stable and long lasting.
What is a post and core procedure?
Post and core procedure is required to retain a crown in cases where a tooth has lost a significant amount of its original structure to decay or trauma. The loss of tooth structure compromises the support of the crown and hence the longevity of the tooth.
Post and core comprises of two physical parts:
A Post, which is a small rod-like structure that goes inside the canal of a root canal treated tooth.
A core, which is an extension of the post outside the tooth and supports the crown of the tooth.
The post helps mechanically retain the core and the crown of the tooth by taking support from inside of the tooth’s root.
How is the need for a Post and core procedure assessed?
In a decayed tooth, the need for a Post and core is assessed after removing the entire decay on the tooth. The remaining natural tooth structure is then examined. If the remaining natural tooth structure is inadequate to provide support and stability to the final crown, then a post and core is indicated in such a case before a crown is fabricated.
