A cracked dental crown can cause discomfort, affect your ability to chew and lead to further complications. The solution depends on the extent of the damage and the materials involved, whether it’s a small crack or a more severe issue. This article explores why crowns crack, how they can be repaired, and the best solutions for different situations.
Can a cracked dental crown be repaired?
Many people wonder whether a cracked dental crown can be fixed or if it needs to be replaced entirely. The answer depends on the type and extent of the damage.
- Minor cracks: Small hairline fractures may be repairable with special dental adhesives or resins.
- Larger cracks: Significant fractures that compromise the integrity of the crown usually require a full replacement.
- Material considerations: Some crowns, such as metal-based ones, may be more difficult to repair compared to porcelain crowns.
It’s essential to visit your dentist for an assessment. They’ll determine if the crack can be repaired or if replacement is necessary. In some cases, your dentist might recommend a temporary fix while you wait for a permanent solution.
Why do dental crowns crack?
Dental crowns are designed to last many years, but can still crack due to various factors. Understanding the causes of a cracked dental crown is key to finding the right solution. Here’s a look at some common reasons why crowns crack:
- Wear and tear: Normal chewing and grinding over time can weaken a crown, leading to fractures.
- Bruxism (Teeth Grinding): Grinding your teeth puts extra pressure on your crown, increasing the likelihood of cracks.
- Improper Fit: A crown that doesn’t fit properly can put excess stress on specific areas, leading to cracks.
- Accidents or trauma: A hard blow to the mouth, whether from a sports injury or dental trauma caused by a motor vehicle accident, can weaken or crack a crown.
- Age of the crown: Over time, crowns can become more brittle and prone to cracking as the materials naturally wear down, especially with constant use and exposure to pressure.
Crowns crack due to external factors, wear, and the materials they’re made from. It’s important to address a cracked crown as soon as you notice any signs to prevent further damage.
Is it better to repair or replace a cracked dental crown?
When it comes to a cracked dental crown, the decision between repairing or replacing it depends on several factors, including the extent of the damage and your personal circumstances. Both options have distinct advantages and potential drawbacks, and your dentist will help guide you in choosing the best solution.
Repairing a cracked dental crown:
- Pros:
- Cost-effective and faster: Repairing a cracked crown is often less expensive than replacement and can typically be completed in just one dental visit, making it a convenient option for those on a budget or with limited time.
- Cons:
- Temporary solution: While a repair can restore some functionality, it may not fully restore the strength and integrity of the original crown. In some cases, the repaired crown might not last as long as a new one, especially if the crack is significant.
Replacing a cracked dental crown:
- Pros:
- Long-lasting and durable: Replacing the crown offers a more permanent solution. The new crown will be stronger and more durable and fully restore the tooth’s function and aesthetics, ensuring better long-term protection.
- Improved appearance: A new crown may also provide a better cosmetic result, as it can be custom-designed to match your natural teeth in colour and shape.
- Cons:
- Higher cost and multiple visits: Replacing a crown typically involves a higher upfront cost and may require multiple dental visits, as the process can take longer due to the need for fitting and creating a new crown.
In the end, your dentist will assess the damage to your crown and help you determine whether repair or replacement is the best option based on the severity of the crack and your individual needs.
Who should you see for a cracked crown?
If you have a cracked dental crown, your first step should be to see a qualified dentist. Choosing a professional experienced in crown repairs and restorative dentistry is crucial for the best outcome. 
- General dentist: For most people, a general dentist can diagnose and treat a cracked crown. They will assess the situation and recommend whether a repair or replacement is necessary.
- Cosmetic dentist: If your crown was part of a cosmetic procedure (such as improving the appearance of your smile), a cosmetic dentist may be the right choice to replace or repair it.
- Specialist: In rare cases, your general dentist may refer you to a prosthodontist, a specialist in restoring and replacing teeth, for more advanced care.
Seeing a dentist promptly is essential to prevent further issues, such as infections or damage to the underlying tooth. Ignoring a cracked crown may result in the need for a root canal or even complete tooth loss, making early intervention crucial.
Which type of dental crown is the most durable?
Not all dental crowns are created equal when it comes to durability. The material your crown is made from significantly affects how long it will last and how resistant it is to cracking.
| Material | Durability | Best For |
| Porcelain | Moderate | Front teeth, aesthetic needs |
| Porcelain-fused-to-metal | High | Back teeth, strong durability |
| Gold | Very High | Back teeth, longevity, wear resistance |
| Zirconia | Very High | Front and back teeth, strength, and aesthetics |
| Resin | Moderate | Temporary crowns or kids’ crowns |
In general, zirconia and gold crowns offer the most durability and resistance to cracking, making them a great option if you want a crown that will last a long time.
Are there ways to prevent dental crowns from cracking?
While some factors contributing to cracked crowns are beyond your control, you can protect your crowns and extend their lifespan in several ways.
- Avoid hard foods: Biting down on hard foods like ice or hard candies can damage your crown. If a crown is already cracked, this damage significantly increases the chance that the dental crown comes completely off.
- Use a night guard: If you grind your teeth, wearing a night guard can protect your crowns from excess pressure.
- Good oral hygiene: Brush and floss regularly to prevent decay and damage around the crown.
- Regular dental visits: Regular check-ups with your dentist ensure that any issues with your crowns are detected early.
These simple steps can help reduce the likelihood of needing a cracked dental crown solution.
Conclusion
A cracked dental crown has a solution, and it doesn’t have to be the end of the world. Depending on the severity of the crack, your dentist may be able to repair it, or they may recommend a replacement. The key is to seek professional help quickly to ensure the best outcome for your dental health. By understanding the factors that cause crowns to crack and the different materials available, you can make an informed decision about your treatment.
