Do You Need a Crown After a Root Canal?

Key Takeaways

• Root canal treatment can greatly weaken the structure of the tooth.
• Crowns provide essential protection to a tooth after a root canal treatment.
• Before a crown is placed, a skilled dentist must thoroughly evaluate your treated tooth and overall dental health.
• It needs to be restored if you want to preserve your tooth (the one that has undergone a root canal) for a long time.

A root canal is a necessary dental treatment to save an infected or damaged tooth. It involves removing the infected pulp and preserving the natural tooth structure. However, the root canal treatment doesn't end here. The next step is to give the treated tooth a crown. Many patients wonder whether a crown is necessary to protect and restore the tooth fully.

In Dr. James C.H. Ko's words, "In a root canal treatment, the dentist removes the tooth's inner living tissue that has become infected. But it can make the tooth more brittle and susceptible to fracture. A crown helps your dentist ensure long-term tooth function and protection."

What Happens to a Tooth After a Root Canal?

When a dentist performs a root canal:

• The infected or damaged pulp is removed
• The inside of the tooth is cleaned and disinfected, and
• The root canals are sealed to prevent further infection.

This process changes the tooth's basic structure by:

• Removing the tooth's blood and nutrients supply
• Reducing tooth hydration and flexibility
• Making the tooth more vulnerable to cracking or breaking, Significantly weakening the overall tooth structure.
• Removes infected or damaged pulp
• Cleans and disinfects the tooth's interior
• Seals the root canals to prevent further infection

This process fundamentally changes the tooth's structure:

• Removes the tooth's blood supply and nutrients
• Reduces tooth hydration and flexibility
• Makes the tooth more prone to cracking or breaking
• Significantly weakens the overall tooth structure

Structural Changes

A root canal treatment is critical to preventing the spread of serious infection to the bone. But it makes a living tooth fragile. The removal of internal tissue compromises the tooth's natural strength. A root canal without crown makes the tooth more vulnerable to:

• Fractures
• Breakage
• Structural collapse
• Potential extraction if not properly protected

When is a Crown Necessary After a Root Canal?

Several factors needs to be considered to understand the need for a crown after root canal:

Tooth Location

• Back teeth (molars and premolars) almost always require crowns
  • Experience more chewing pressure
  • More likely to break without additional protection
• Front teeth may sometimes be treated with large fillings

Extent of Damage

Crowns become crucial when:

• Significant tooth structure is lost
• Large portions of the tooth are removed during the root canal
• Tooth is extensively decayed before treatment
• Patient has a history of teeth grinding or clenching

Benefits of Getting a Crown After a Root Canal

• Front teeth with less structural compromise
• Teeth with less biting load

Drawbacks of Avoiding a Crown

• Increased risk of tooth fracture
• Potential need for future extraction
• Compromised chewing ability
• Higher long-term dental costs

3. What happens if I don't get a crown?

Without a crown, the tooth is exposed to an increased risk of tooth fracture. You may even have to undergo a tooth extraction.

4. Are crowns painful to get?

The procedure is typically performed with local anesthesia and minimal discomfort.

1. How long do crowns last?

With proper care, your dental crown may last 10-15 years or longer.
