Dental crowns are one of the most common restorative dental treatments, providing both functional support and cosmetic enhancement. Whether you need a crown due to tooth damage, decay, or aesthetic concerns, one question always comes to mind—how long do crowns last?
The answer isn’t straightforward. The longevity of a dental crown depends on several factors, including the type of material used, oral hygiene habits, bite force, and overall dental health. Some crowns can last decades, while others may need replacement after just a few years.
In this Supremia Dentistry guide, we’ll take a deep dive into dental crowns, covering everything from different crown types and their lifespans to how to care for them, signs of wear, and when to replace them.
What Are Dental Crowns?
A dental crown is a tooth-shaped cap placed over a damaged or weakened tooth to restore its strength, function, and appearance. It protects the structure from further damage while allowing you to chew and smile confidently.
Crowns can be customized to match the color and shape of your natural teeth, making them aesthetic and functional solutions for various dental problems.
Why Do People Need Dental Crowns?
Dentists recommend crowns for multiple reasons, such as:
- Protecting a weak or cracked tooth (e.g., after a large filling or root canal).
- Restoring a broken, worn-down, or misshapen tooth.
- Covering and reinforcing a dental implant.
- Holding a dental bridge in place.
- Improving the appearance of severely discolored or misshapen teeth.
If your dentist has suggested a crown, it’s likely because your tooth needs extra support that a simple filling or bonding can’t provide.
Importance of Crown Longevity
The longevity of a crown is crucial for several reasons:
- Cost-effectiveness: Replacing crowns frequently can be expensive, so a longer lifespan translates to significant cost savings.
- Oral health: A well-maintained crown protects the underlying tooth from further decay or damage, preserving your natural tooth structure.
- Comfort: A properly fitting crown ensures comfortable chewing and biting, allowing you to enjoy your favorite foods without pain.
- Aesthetics: A crown that lasts maintains your smile’s appearance, keeping your smile looking its best for years to come.
Average Lifespan of Dental Crowns
As mentioned earlier, the average lifespan is 5-15 years. But this is just an average. Some crowns last much longer, while others may need replacement sooner.
This range highlights the importance of understanding the factors that influence crown longevity.
How Long Do Different Crown Materials Last?
The material your crown is made from plays a significant role in its longevity. Different materials have different strengths and weaknesses, which directly impact their durability and lifespan.
Factors That Impact Crown Longevity
Several factors can influence how long your crown lasts. These include the material used, your oral hygiene, your bite, and the skill of the dentist placing the crown. We will explore those factors in detail in the following sections.
When Should You Replace a Crown?
Knowing when to replace a crown is just as important as knowing how long it should last. Ignoring a damaged or failing crown can lead to more serious dental problems.
We’ll discuss the signs that indicate a crown needs replacement later in this article.
Types of Dental Crowns and Their Longevity
Let’s explore the different types of crowns and their typical lifespans:
Porcelain Crowns
Porcelain crowns are popular for their natural look, mimicking the color and translucency of natural teeth. They are a great choice for restoring front teeth where aesthetics are paramount.
Pros and Cons of Porcelain Crowns
- Pros: Excellent aesthetics, biocompatible, natural-looking.
- Cons: Can be brittle, more prone to chipping than metal crowns, may not be suitable for back teeth with heavy biting forces.
Lifespan and Durability
Porcelain crowns typically last 7-15 years with proper care.
Metal Crowns (Gold, Silver, and Alloys)
Metal crowns are made from gold, silver, or other metal alloys. They are known for their strength and durability.
Pros and Cons of Metal Crowns
- Pros: Highly durable, can withstand biting forces, long-lasting.
- Cons: Less aesthetic, metal taste can be a concern for some, may not be suitable for people with metal allergies.
Lifespan and Durability
Metal crowns are the most durable, often lasting 10-20 years or even longer.
Porcelain-Fused-to-Metal (PFM) Crowns
PFM crowns have a metal base covered by porcelain. They offer a compromise between strength and aesthetics.
Pros and Cons of PFM Crowns
- Pros: Good balance of aesthetics and strength, more affordable than all-porcelain crowns.
- Cons: Porcelain can chip, metal margin may become visible over time, not as aesthetically pleasing as all-porcelain crowns.
Lifespan and Durability
PFM crowns generally last 7-12 years.
Zirconia Crowns
Zirconia crowns are made from a strong, ceramic material. They offer excellent durability and a natural appearance.
Pros and Cons of Zirconia Crowns
- Pros: Highly durable, aesthetically pleasing, and biocompatible.
- Cons: Can be more abrasive to opposing teeth and can be more expensive than other options.
Lifespan and Durability
Zirconia crowns can last 10-15 years.
Composite Resin Crowns
Composite resin crowns are made from a tooth-colored resin material. They are a more affordable option.
Pros and Cons of Composite Resin Crowns
- Pros: More affordable, can be matched to the color of your teeth.
- Cons: Less durable, prone to chipping and staining, not as long-lasting as other options.
Lifespan and Durability
Composite resin crowns typically last 5-7 years.
Factors That Affect the Lifespan of Dental Crowns
Several factors can influence the longevity of your dental crown:
Material Quality and Strength
The quality of the materials used and the skill of the dental technician fabricating the crown are essential. A well-made crown from high-quality materials will last longer.
Oral Hygiene and Daily Care
Brushing, flossing, and regular dental checkups are crucial for maintaining crown health.
Proper oral hygiene helps prevent decay and gum disease, which can affect the health of the underlying tooth and the surrounding gums.
Teeth Grinding and Bite Force
Bruxism (teeth grinding) and excessive bite force can damage crowns. These habits can put undue stress on the crown, leading to cracks, chips, or even breakage.
Placement and Fit of the Crown
A properly fitted crown is less likely to experience problems. A crown that doesn’t fit correctly can lead to issues like food impaction, gum irritation, and even bone loss.
Gum Health and Underlying Tooth Condition
Healthy gums and a strong underlying tooth are essential for crown longevity. If the gums are unhealthy or the underlying tooth is compromised, the crown’s lifespan can be significantly reduced.
Signs That a Dental Crown Needs Replacement
Keep an eye out for these signs:
Cracks, Chips, and Wear
Visible damage to the crown, such as cracks, chips, or excessive wear.
Pain or Sensitivity
Pain when biting or sensitivity to hot or cold, which could indicate a problem with the crown or the underlying tooth.
Loose or Detached Crown
A crown that feels loose or has come off completely. This requires immediate attention from your dentist.
Gum Recession Around the Crown
Receding gums can expose the margin of the crown, making it more susceptible to decay and other problems.
How to Extend the Life of Your Dental Crown
Here are some tips to maximize your crown’s lifespan:
Proper Oral Hygiene Practices
Brush twice daily, floss once daily, and use mouthwash. Pay special attention to cleaning around the crown to remove plaque and food particles. A soft-bristled toothbrush is recommended to avoid scratching the crown.
Avoiding Hard and Sticky Foods
Avoid chewing on hard candies, ice, or sticky foods, as these can damage the crown. Sticky foods can also pull on the crown, potentially loosening it.
Using a Mouthguard for Teeth Grinding
If you grind your teeth, wear a nightguard to protect your crown from excessive force. A custom-fitted mouthguard from your dentist is the most effective option.
Regular Dental Checkups and Maintenance
Visit your dentist for regular checkups and cleanings. These visits allow your dentist to monitor the health of your crown and address any potential problems early on.
Professional cleanings also remove plaque and tartar buildup, which can contribute to gum disease.
Are Crowns a Permanent Solution?
While crowns can last for many years, they are not a permanent solution.
It’s important to have realistic expectations about the lifespan of your crown. While they are designed to be durable, they are still subject to wear and tear.
