Do’s and Don’ts of Post and Core Procedure in Dentistry

In the world of dental restoration, the post and core procedure stands out as an essential means of salvaging the natural tooth structure and providing a robust foundation for the placement of a crown. However, this procedure requires precision and thorough understanding by both the dentist and dental clinic staff. Whether you’re a seasoned dental professional or a curious patient, it’s vital to be well-informed about the do’s and don’ts of this treatment. Join us, a leading dental clinic, as we explore the nuances of post and core, shedding light on the best practices and when this procedure, executed by skilled dentists, is the right fit for your dental needs.

What is Post and Core in Dentistry?

The term ‘post and core’ in dentistry refers to a dental restoration procedure necessary when the natural crown of the tooth is severely damaged or compromised. The core is the foundation that supports the post, which in turn provides stability to the crown placed on top. This technique is often employed when there is insufficient tooth structure for a crown to be placed directly, or when additional support is needed.

The Purpose of Post and Core

Post and core procedures have both functional and aesthetic purposes. Functionally, they restore the tooth’s ability to withstand the pressures of daily biting and chewing, while aesthetically, they can improve the overall appearance of the tooth.

When is a Post and Core Necessary?

There are several scenarios in which a post and core becomes necessary:

  • After a root canal treatment to rebuild tooth structure.
  • When a tooth is severely damaged by decay or trauma, leaving little healthy structure for a restoration.
  • To support the retention of large restorations that can’t be adequately supported by the remaining tooth structure alone.

Do’s and Don’ts of Post and Core

Performing a post and core requires meticulous attention to detail, and there are certain practices that must be followed to ensure a successful restoration.

The Do’s of Post and Core:

Do Proper Case Selection

Not every tooth that undergoes root canal treatment requires a post and core. Case selection should be based on the amount of tooth remaining, the tooth’s position in the mouth, and individual patient factors.

Ensure Adequate Tooth Structure

A post and core is only as strong as the remaining tooth structure it’s placed in. The tooth should have sufficient structure to support the post and core without the risk of fracture.

Material Selection

Choosing the correct post and core materials is critical. Factors to consider include the strength of the material, the fit in the canal, and the material’s compatibility with the final restoration.

The Don’ts of Post and Core:


Excessive preparation can weaken the tooth and increase the risk of root fracture. It’s important to be conservative in the removal of tooth structure.

Use of the Wrong Post

Selecting the wrong type of post can lead to poor retention, fit, or adaptation in the canal. This can result in broken posts or cores or failure of the final restoration.

Poor Isolation

Isolation is crucial in preventing contamination of the post space. Any contamination can lead to failure of the post and core, the root canal treatment, or the final restoration.

When to Do Post and Core

Deciding whether to proceed with a post and core procedure involves several considerations. Indications for this procedure include but are not limited to:

  • Teeth that have been weakened or lack sufficient retention for a crown.
  • Teeth that have received root canal therapy.
  • Teeth with extensive decay or prior large restorations.
  • When a crown is needed, but there is inadequate tooth structure to support it directly.

Different Scenarios for Post and Core

Post and core procedures can vary based on the specific tooth involved and the desired outcome. Each scenario demands a unique approach.

Post and Core for Molars

Molars present unique challenges due to their location and function. The post and core must be robust enough to endure the significant forces placed on these back teeth during chewing.

Post and Core with Crown

The combination of a post and core with a crown, usually involving a two-visit procedure, can provide excellent functional and aesthetic outcomes, particularly for anterior teeth.

Post and Core Without Root Canal

Uncommonly, a post and core may be placed without a root canal. This could be considered in select cases where the tooth is healthy, and no further endodontic (pertaining to root canal) treatment is indicated.

Post and Core vs. Build-Up

While post and core and build-up are both tooth foundation procedures, there are distinct differences in their application and purpose.

Understanding Build-Up

A build-up restores fractured or decayed teeth. It involves a filling material that builds up the tooth, but unlike a post and core, may not include a post.

When to Choose Build-Up Over Post and Core

A build-up is generally used on teeth with one or several surfaces to restore, typically when there is enough tooth structure remaining to support a crown.


The post and core procedure is a critical element in dental restoration, bridging the gap between severe tooth damage and functional aesthetics. By understanding the nuances and application of this technique, dental professionals can ensure the best possible outcome for their patients. It’s always recommended to consult with your oral healthcare professional for personalized advice on whether a post and core is the right choice for your dental health needs. Remember, the goal is not just to restore a tooth, but to maintain a healthy smile for a lifetime.
