Fixing a Broken Crown

A dental crown is designed to protect and strengthen a damaged tooth, but it isn’t indestructible. Over time, crowns can break, crack, or become loose. If this happens, it’s important to address the issue as soon as possible to prevent further damage to your tooth. Here’s what you need to know about fixing a broken crown and getting your smile back on track.

Fixing a Broken Crown

Why Do Crowns Break?

Dental crowns are made from durable materials like porcelain, ceramic, or metal. They can still break under certain conditions. There are several common causes of crown damage. Chewing ice, hard candy, or nuts can put excessive pressure on the crown, causing it to crack or chip. Bruxism, or grinding your teeth at night, can wear down or weaken the crown over time.

A fall, sports injury, or other accident can lead to a broken crown. Crowns don’t last forever. Over time, the materials can degrade, making them more prone to damage. If a crown isn’t fitted properly, it may be more likely to loosen or break.

How Dentists Fix Broken Crowns

The treatment for a broken crown depends on the extent of the damage. We have several ways that we can repair your broken crown. 

  1. Minor Chips or Cracks: If the crown is only slightly damaged, your dentist may be able to repair it with dental bonding or polish the surface to restore its appearance.
  2. Reattaching a Loose Crown: If the crown has come off but is still intact, your dentist can clean it and securely reattach it with dental cement.
  3. Replacing the Crown: If the crown is severely damaged or cannot be repaired, your dentist will take impressions of your tooth and create a new custom crown.
  4. Addressing the Underlying Tooth: In some cases, the damage may extend to the natural tooth beneath the crown. Your dentist may need to treat decay, perform a root canal, or adjust the tooth before placing a new crown.

Preventing Crown Damage

To extend the life of your dental crowns and avoid future problems, follow these tips:

  1. Avoid Hard or Sticky Foods: Steer clear of foods that can crack or dislodge your crown.
  2. Wear a Nightguard: A custom nightguard can protect your crowns and natural teeth if you grind your teeth.
  3. Practice Good Oral Hygiene. Brush and floss regularly to prevent decay or gum disease, which can weaken the tooth supporting the crown.
  4. Visit Your Dentist Regularly: Routine checkups allow your dentist to monitor the condition of your crowns and address any issues early.

When to Seek Emergency Care

A broken crown is usually not a dental emergency, but you should seek immediate care if:

  • You’re experiencing severe pain or swelling.
  • The underlying tooth is exposed and extremely sensitive.
  • There are sharp edges from the broken crown that could injure your mouth.

A broken crown doesn’t have to disrupt your life. With prompt attention and the right care, your dentist can restore your smile and protect your oral health. If you have concerns about a damaged crown, don’t hesitate to reach out to your dentist for guidance.

Frequently Asked Questions

What should I do if my dental crown falls off?

If your crown falls off, keep it safe and contact your dentist immediately. Avoid chewing on the affected side, and use dental cement or toothpaste to temporarily reattach the crown if needed. Your dentist will assess whether it can be re-cemented or if a replacement crown is required.

Why does my crown feel loose, and how can it be fixed?

A loose crown can result from weakened cement, tooth decay underneath, or damage to the crown itself. Your dentist will remove the crown, clean the area, and either re-cement it or recommend a replacement if the crown or underlying tooth structure is compromised.

How does the age of a crown affect the decision to repair or replace it?
The age of a dental crown plays a significant role in the decision to repair or replace it. Older crowns, typically over 10–15 years, may have weakened materials or underlying tooth decay, making replacement more practical. Newer crowns with minor damage, like chips, are often repairable with bonding or polishing, provided the structure is intact.

What are the potential risks of delaying the repair or replacement of a damaged crown?
Delaying the repair or replacement of a damaged crown can expose the underlying tooth to decay, infection, or further structural damage. A loose or cracked crown may also cause discomfort, gum irritation, or difficulty chewing. Prolonged neglect increases the likelihood of needing more extensive and costly treatments, such as root canals or extractions.

How does the material of the crown affect repair options?
The crown material affects the repair approach significantly. Porcelain and ceramic crowns can often be repaired with composite resin or bonding for minor chips, while metal crowns are typically more durable but harder to repair. In cases of severe damage, replacement is more likely, regardless of the material. Your dentist will evaluate the best option based on the crown type and damage.

What should I do if food gets stuck around my crown?
If food gets stuck around your crown, floss gently around the area using a floss threader if needed, and rinse with water or mouthwash. Persistent food traps may indicate a poor crown fit or gum recession. If the issue continues, consult your dentist to adjust or replace the crown to prevent decay or gum irritation.
