Understanding Post and Core Treatment
A post and core build-up is a restorative procedure used to strengthen a tooth after root canal treatment when a large amount of the natural tooth structure has been lost. The procedure creates a solid foundation for a permanent dental crown, helping restore strength, stability, and long-term function. At Dr. Mexico Dental Group, we typically use modern fiberglass posts that bond securely inside the tooth and can usually be completed in a single visit. For patients with severely broken or weakened teeth, a post and core may be part of a larger full-mouth rehabilitation plan. When a tooth has only minor damage, a composite filling may be enough; when more structure is missing, a post and core may be needed before a crown.
If you’ve been told you need a post and core build-up after a root canal, our experienced dentists can restore your tooth with modern, durable materials designed to support a long-lasting crown. Schedule a consultation to learn about your treatment options in Tijuana.
Although many people think a root canal weakens a tooth, the real issue is that teeth requiring root canal treatment have often already lost a significant amount of their natural structure due to decay, fractures, or large old fillings. A post and core build-up restores internal support, helping preserve the tooth and prepare it for long-term restoration.
At Dr. Mexico Dental Group, we typically use modern fiberglass posts because they bond securely with advanced dental resin and closely match the flexibility of natural tooth structure. Unlike traditional cast metal posts, fiberglass posts can usually be placed in a single appointment without laboratory fabrication, making treatment more efficient while providing excellent long-term support.
By combining root canal therapy, a properly placed fiberglass post, a durable core build-up, and a custom dental crown, our dentists can often restore teeth that might otherwise require extraction. This conservative approach helps patients keep their natural teeth while restoring normal appearance, strength, and chewing function for many years.
The Fiberglass Post
A fiberglass post is placed inside the root canal after the root canal treatment has been completed. The post is bonded into the root using a strong dental resin, providing internal reinforcement much like steel reinforcing bars strengthen concrete. This support helps the tooth withstand everyday chewing forces.
The Core Build-Up
After the fiberglass post is securely bonded in place, a tooth-colored composite core is built around it. This recreates the missing portion of the tooth, allowing the dentist to prepare the tooth for a strong, natural-looking dental crown.
The Benefits of Post and Core Treatment
Preserve Your Natural Tooth
Rather than removing a damaged tooth, a post and core build-up allows us to restore and preserve your natural tooth whenever possible.
Reinforces Weakened Teeth
Root canal-treated teeth often have extensive decay or large old fillings. A fiberglass post helps reinforce the remaining tooth structure before a crown is placed.
Provides a Strong Foundation
The post and core create a stable base that allows the dental crown to fit securely and function properly for many years.
Helps Prevent Fractures
By strengthening the inside of the tooth, a post and core build-up helps reduce the risk of the remaining tooth breaking during normal chewing.
Restores Normal Function
Once restored with a crown, most patients are able to chew comfortably and confidently again.
Why Choose Dr. Mexico Dental Group?
Modern Fiberglass Technology
We routinely use fiberglass posts instead of traditional cast metal posts because they bond well to modern dental materials, provide excellent support, and often eliminate the need for laboratory fabrication.
Conservative Dentistry
Whenever possible, we focus on saving natural teeth rather than extracting or removing them. A properly restored tooth can often continue functioning for many years.
High-Quality Restorations
We use quality adhesive materials and modern restorative techniques designed to provide durable, long-lasting results.
Personalized Treatment
Every tooth is different. Our dentists carefully evaluate how much healthy tooth structure remains before recommending whether a post and core build-up is necessary.
The Post and Core Build-Up Procedure
Step 1 – Complete the Root Canal
The infected nerve and pulp tissue are removed from inside the tooth. The canals are thoroughly cleaned, disinfected, and sealed to eliminate infection.
Step 2 – Prepare the Root for the Post
A small portion of the root canal filling is removed to create space for the fiberglass post while preserving the seal created during the root canal.
Step 3 – Bond the Fiberglass Post
The post is fitted into the canal and permanently bonded using a strong dental resin cement. This creates internal reinforcement for the weakened tooth.
Step 4 – Build the Core and Prepare for the Crown
Composite resin is placed around the post to rebuild the missing tooth structure. The tooth is then shaped to receive a custom dental crown, which protects the tooth and restores full function.
Frequently Asked Questions About Post and Core Build-up
What is a post and core build-up?
A post and core build-up is a restorative procedure used after root canal treatment to strengthen a tooth that has lost a significant amount of its natural structure before placing a dental crown.
Does every root canal need a post?
No. Many teeth can be restored without a post. A post is typically recommended when too much natural tooth structure has been lost to adequately support a crown.
Why do you use fiberglass posts instead of metal posts?
Modern fiberglass posts bond well with adhesive dental materials, closely match the flexibility of natural tooth structure, are tooth-colored, and usually eliminate the need for laboratory fabrication.
Is the procedure painful?
No. The procedure is performed using local anesthesia, and most patients experience little discomfort during treatment.
Will I still need a dental crown?
In most cases, yes. The post strengthens the inside of the tooth, while the crown protects the remaining tooth from future fracture.
How long do fiberglass posts last?
With proper oral hygiene, routine dental care, and a well-fitting crown, a fiberglass post can provide many years of reliable support.
Can an old metal post be replaced?
Yes. In some situations, an existing metal post can be safely removed and replaced if additional treatment or retreatment is necessary.
Is a post the same as a root canal?
No. A root canal removes infection from inside the tooth. A post is placed afterward to reinforce the tooth when additional support is needed before placing a crown.
Restore and Protect Your Tooth with a Strong Foundation
A damaged or weakened tooth does not always need to be removed. A post and core build-up can restore the strength and structure needed to support a dental crown, helping preserve your natural tooth and return comfortable function to your smile.

Root Canal Treatment If your tooth has an infected or damaged nerve, root canal therapy removes the infection and saves the tooth. A post and core build-up may be recommended afterward when additional support is needed before placing a crown
Root Canal Retreatment If a previous root canal has failed, retreatment can remove persistent infection and give the tooth a second chance. Once healing is complete, a post and core may again be used to reinforce the tooth before restoring it.
Dental Crowns Most teeth restored with a post and core build-up are protected with a custom dental crown. The crown restores strength, appearance, and normal chewing function while protecting the remaining tooth.
Composite Fillings When only a small amount of tooth structure is missing, a composite filling may be all that’s needed. Larger defects often require a post and core before a crown can be placed.
Tooth Extractions When a tooth is too severely damaged to be restored with root canal treatment and a post and core, extraction may be the best option. Our dentists always evaluate whether the tooth can be saved before recommending removal.
