A chipped dental crown can be both frustrating and concerning. Whether the damage is barely noticeable or clearly visible when you smile, it’s important to have the crown evaluated promptly. While some chipped crowns can be repaired, others may require replacement depending on the severity of the damage and the crown material.
In this guide, we’ll cover everything you need to know about chipped crown repair, including costs, treatment options, crown materials that are more prone to chipping, and when it’s time to see a dentist.
What Does a Chipped Crown Look Like?
A chipped dental crown can appear in several different ways depending on the material and extent of the damage.
Common signs include:
- A small missing piece along the edge of the crown
- Rough or sharp surfaces
- Visible cracks in the porcelain
- Changes in the crown’s shape
- Dark or metallic areas showing through
- Sensitivity when biting or chewing
Many patients first discover a chipped dental crown when they feel a rough edge with their tongue rather than seeing the damage in a mirror.

Why Do Dental Crowns Chip or Break?
Dental crowns are made from tough, durable materials and can last 15 to 20 years or longer. However, one or more of the following factors may increase the chances of crown chipping or damage over time.
1. Biting Hard Foods
Chewing hard foods such as ice, nuts, hard candy, or popcorn kernels can place excessive pressure on a crown and cause it to chip.
2. Teeth Grinding (Bruxism)
Chronic grinding or clenching of teeth can weaken the crown over time, increasing the risk of cracks and chips.
Wearing a night guard may help prevent a crown from chipping in patients with bruxism.
3. Accidental Trauma or Injury
Falls, sports injuries, or direct impacts to the mouth can damage the crown and lead to chipping.
4. Normal Wear and Tear
Daily chewing and years of use can gradually wear down crown materials, making them more susceptible to damage.
5. Poor Bite Alignment
An uneven bite can create excessive force on specific areas of the crown, leading to fractures or chips.
6. Using Teeth as Tools
Opening packages, biting fingernails, or holding objects with your teeth can put unnecessary stress on a dental crown.
7. Weak or Thin Crown Material
Crowns that are too thin or made from less durable materials may be more likely to chip under pressure.
8. Underlying Tooth Structure Problems
Decay or weakening of the tooth beneath the crown can reduce support and contribute to crown damage.
9. Improper Crown Fit
A crown that does not fit correctly can experience uneven pressure, increasing the chance of chipping.
10. Age of the Crown
Older crowns may become more vulnerable to damage as materials naturally deteriorate over time.

Can a Chipped Crown Be Repaired?
Yes, a chipped dental crown can be repaired depending on the extent of the damage.
Small chips are often cosmetic and can be restored using composite bonding or smoothing techniques. In these situations, the crown may continue to function normally after treatment.
However, deeper fractures can weaken the restoration and make replacement the better long-term option. Even if you have a chipped crown with no pain, it is worth having it assessed. Pain is not always present when a crown is damaged, and delaying treatment may allow the chip to worsen.
How to Repair a Chipped Crown?
Dentists choose the repair method based on the location and severity of the chip.
Composite Bonding
A tooth-coloured resin is applied to restore the missing portion of the crown. This is commonly used for minor cosmetic defects.
Polishing
If the damage is limited to a rough edge or tiny surface chip, polishing may be enough to improve comfort and appearance.
Crown Replacement
When a significant portion of the crown has fractured or its structural integrity has been compromised, replacing the restoration may be the most predictable solution.
If you notice a chipped crown, avoid chewing hard foods on that side until you can see your dentist.

Which Crown Types Chip Most Frequently?
Certain crown materials are more prone to chipping than others.
Porcelain-Fused-to-Metal (PFM) Crowns
PFM crowns are among the restorations most commonly associated with chipping.
These crowns consist of a metal framework covered with a porcelain outer layer. Although the metal provides excellent strength, the porcelain veneer can fracture over time. When this happens, the underlying metal becomes visible as a dark, silver, or grey area.
All-Ceramic Crowns
All-ceramic crowns (porcelain jacket crowns) offer exceptional aesthetics and a natural appearance. While they are durable, they can be more vulnerable to chipping under excessive force, especially in patients who clench or grind their teeth.
Zirconia Crowns
Monolithic zirconia crowns are among the strongest restorations available today. They are generally less likely to chip than traditional porcelain-based crowns and are often recommended for patients with heavy bite forces.
Metal Crowns
Gold and full-metal crowns rarely chip because they do not contain porcelain. Instead, they tend to wear gradually over many years.

How Much Does It Cost to Fix a Chipped Crown?
The chipped crown repair cost depends on the severity of the damage and the treatment required.
A minor chip affecting only the surface of the crown is often less expensive to address than a fracture that impacts the crown’s strength or appearance. The material used for the restoration and the overall condition of the crown can also influence treatment costs.
Factors that may affect the cost include:
- The size of the chip
- The crown material
- The location of the tooth
- The age of the restoration
- Whether repair or replacement is needed
As a rough estimate, prices usually fall between $300 and $3,000. An examination by your dentist is the best way to determine the most appropriate treatment and associated costs.
Conclusion
A chipped dental crown is a common dental issue, but it doesn’t always mean the crown needs to be replaced. Minor chips can often be corrected through conservative chipped dental crown repair techniques, while larger fractures may require a new restoration. PFM crowns are particularly prone to porcelain chipping, which can expose the metal core beneath the surface, whereas zirconia crowns are generally more resistant to damage.
Whether you’re concerned about appearance, comfort, or the chipped crown repair cost, an early dental assessment can help protect both the crown and the underlying tooth.
