FAQ
What is a post and core?
A straight answer first, then the context behind it, from the technicians who do the work.
THE SHORT ANSWER
A post and core is a two-part restorative foundation placed inside a tooth after root canal therapy. The post anchors into the root canal space for retention; the core rebuilds the coronal tooth structure lost to decay or fracture. Together they create the stable base a crown needs to seat correctly and function long-term.
THE CONTEXT
What sits behind it
When a tooth has lost too much natural structure to retain a crown on its own, a post and core fills that gap. The post, typically cast metal, fiber-reinforced composite, or zirconia, seats into one or more prepared root canals. The core material, usually composite resin or cast metal, reconstructs the missing coronal anatomy. Final crown prep then follows on that rebuilt foundation rather than on compromised tooth structure.
For endodontists and their restorative referral partners, post and core turnaround directly affects how quickly patients move from completed root canal therapy to a protected, crowned tooth. A delay of more than a few days increases the fracture risk on an unprotected tooth. Lab fabrication of a cast post and core typically runs 3-5 business days; prefabricated post with a direct composite core can be placed chairside the same appointment, depending on the clinical situation.
Dani Dental fabricates cast post and core restorations with same-day prescription acknowledgment and a 3-business-day standard turnaround from impressions received. Each case ships with the technician's direct line so the referring restorative dentist can confirm seating specs before the patient's crown appointment, keeping the handoff clean across both offices.
