If you’ve been told you need a post and core before getting a dental crown, you may be wondering:
What is it? Why do I need it? And how does it fit into the treatment plan?
Don’t worry — we’ve got you covered. A post and core is a common restorative procedure used to help rebuild a tooth that’s been significantly damaged, especially after a root canal. It plays a key role in strengthening the foundation for a long-lasting crown.
Here’s what it is, why it’s needed, and what to expect from the procedure.
🦷 What Is a Dental Post and Core?
A post and core is a two-part structure that’s placed inside a severely damaged or root canal-treated tooth to provide internal support before placing a crown.
The post is inserted into the tooth’s root canal to help anchor the restoration.
The core is a buildup material that replaces missing tooth structure and helps support the crown.
Together, the post and core act like an artificial foundation, giving your new crown something strong and stable to attach to.
🔍 When Is a Post and Core Needed?
You may need a post and core if:
- You’ve had a root canal, and the tooth no longer has enough structure left to support a crown
- A large portion of the natural tooth is missing due to decay, fracture, or previous restorations
- Your dentist wants to ensure maximum strength and stability for the crown
Not every root canal-treated tooth requires a post and core — but in cases with minimal remaining tooth, it’s often the best way to protect your investment in the crown.
🛠 What Materials Are Used?
Posts can be made of metal, fibreglass, or ceramic, depending on the tooth’s location and aesthetic goals.
Cores are typically made of tooth-coloured composite resin or dental amalgam for back teeth.
Your dentist will choose materials based on strength, durability, and appearance — especially for front teeth where a natural look is important.
👣 What’s the Procedure Like?
The post and core procedure typically follows a root canal and happens before your crown placement:
- Root canal is completed and the tooth is disinfected and sealed.
- Your dentist or specialist places the post into the cleaned canal, using dental cement to secure it.
- The core buildup is shaped around the post to mimic the natural tooth structure.
- Once healed, the tooth is prepped for a crown, which is then placed in a follow-up appointment.
It’s usually done with local anaesthetic, and most patients experience minimal discomfort.
💡 Why Is a Post and Core Important?
- Restores teeth with significant damage or missing structure
- Provides a strong base for crowns to prevent breakage or loosening
- Helps distribute bite forces evenly to reduce risk of future fractures
- Supports long-term function and appearance
Without a post and core, a crown on a weakened tooth may not hold up — leading to failure, fracture, or even tooth loss.
🗓 How Long Does It Last?
With proper care, a post and core — along with your crown — can last many years. The key is:
- Good oral hygiene (brushing, flossing, regular cleanings)
- Avoiding habits like grinding or chewing ice
- Routine dental check-ups to monitor the restoration
Final Thoughts
A post and core may not be something you think about often, but it plays a vital role in restoring strength, function, and confidence to your smile — especially after root canal treatment. If your dentist recommends one, it’s to give your crown the best possible chance of long-term success.
