If your dentist has recommended a post and core treatment after a root canal, you may wonder why it is necessary. When a tooth has lost a significant amount of its structure due to decay, trauma, or previous dental work, a post and core restoration provides the support needed before placing a dental crown. This article explains the procedure, benefits, and when it is recommended.
Who Is This Article For?
This article is for patients who have recently undergone root canal treatment, those advised to get a dental crown, individuals with severely damaged teeth, or anyone looking to understand why a post and core restoration may be recommended before crown placement.
Post and Core consists of 2 Parts
- Post: Usually a small rod made up of metal or fibre and inserted into the root space of the tooth with a couple of millimetres above the canal orifice. The post is used to hold the core filling material. Post is inserted into the root canal hence a root canal treated tooth.
- Core: Core is a build-up of filling material which holds the post in place. It replaces missing tooth structure so that a crown can be placed over it. The core is made up of composite polymers such as light cure GIC or resin materials. Core is used to hold the crown in place.
Dental restoration can be a single unit or a retainer crown for dental bridges. A dental crown’s stability depends on the amount of tooth structure that extends into the interior. If a very little tooth structure occupies the space the crown can be dislodged by forces directed on it. The core re-builds the tooth closer to its original shape thus increasing the crown stability and long-term success.
Indications: Large part or all of the tooth structure lost is seen in decay or tooth trauma. A post and core can be done only if the tooth has undergone a root canal treatment.
Treatment procedure for root canal
After the Endodontics procedure, some of the Gutta Percha is removed from the canal space to place the post. The post space is created using specialized instruments available in different sizes. An appropriate post is selected and verified with the help of an IOPA. Post length should be 3/4th of the entire tooth length in order to acquire stability. Post is then coated with luting materials like GIC or resin. A stable core build-up material is then placed to form the tooth crown. Post and core is considered as an alternative to tooth extraction, thus saving the natural teeth.
Post and core is a dental restoration procedure which is performed after a root canal treatment. The purpose of a post and core is to save an existing tooth that has lost a significant amount of its internal structure. A post and core helps anchor a dental crown on top of a tooth to shield it from further damage.

FAQ’s
1. Is a post and core necessary after every root canal?
No. It is recommended only when the tooth has lost significant structure and requires additional support for a dental crown.
2. Is post and core treatment painful?
The procedure is performed on a tooth that has already undergone root canal treatment, so patients generally experience minimal discomfort.
3. How long does a post and core restoration last?
With proper oral hygiene and regular dental check-ups, it can last for many years.
4. Can I get a dental crown without a post and core?
Yes, if enough healthy tooth structure remains. Your dentist will determine whether a post and core is necessary.
5. Does a post strengthen the tooth?
A post primarily helps retain the core and crown. It does not strengthen the tooth itself but provides support for the final restoration.
