If you’ve recently gotten a crown for a broken tooth or are considering one, you’re probably wondering how long it will last. Dental crowns are designed to be long-lasting, but their exact lifespan depends on many factors, from the material used to how well you care for your teeth.
In this guide, our dentists at The Advanced Dental Center of Cedar Knolls explain what affects the dental crown lifespan, how to protect your restoration, and when replacement might be needed.
What Is a Dental Crown?
A dental crown is a custom-made cap placed over a damaged, decayed, or weakened tooth. It restores your tooth’s shape, strength, and appearance while protecting it from further harm. Crowns are also used after endodontic therapy (root canal treatment) or as part of affordable dental implants in NJ.
Crowns can be made from several materials, each offering different benefits for durability and aesthetics.
How Long Do Dental Crowns Typically Last?
According to the American Dental Association (ADA), the average life of a dental crown ranges from 10 to 15 years. However, with proper care, many crowns can last 20 years or longer.
| Crown Material | Average Lifespan | Best For |
| Porcelain/Ceramic | 10–15 years | Front teeth, aesthetics |
| Porcelain-fused-to-metal (PFM) | 10–20 years | Strength + appearance |
| Gold alloy | 20+ years | Molars, heavy biters |
| Zirconia | 15–20 years | Long-lasting durability |
| Emax (Lithium Disilicate) | 15+ years | High strength & beauty |
If you’re curious about porcelain/ceramic dental crowns or the Emax crowns cost, your dentist can recommend the best option based on your tooth’s location and your cosmetic goals.
What Affects the Lifespan of Dental Crowns?
Even the most durable crown can fail early if certain conditions aren’t met. Here are the main factors that determine how many years a dental crown lasts:
1. Material Choice
- Porcelain and ceramic look natural but are more prone to chipping.
- Zirconia and Emax offer exceptional durability with a realistic look.
- Metal crowns resist wear best but aren’t ideal for visible teeth.
2. Dental Hygiene Habits
Good oral hygiene is the single most important factor. Brush twice daily with fluoride toothpaste, floss gently around the crown, and use antibacterial mouthwash.
3. Bite Pressure and Teeth Grinding
Grinding (bruxism) can wear down crowns prematurely. If you grind your teeth, ask your dentist about a night guard or TMJ pain relief options.
4. Gum Health
Healthy gums keep the crown margins sealed and protected. Gum recession or inflammation can expose the crown’s edge, leading to decay beneath it.
5. Dental Technique and Technology
Crowns made using CEREC same-day crowns or designed with CBCT scan dental imaging often fit more precisely, which improves longevity and comfort.
How to Make Your Dental Crown Last Longer
If you want to extend your dental crown’s life beyond 15 years, follow these steps:
- Brush gently twice a day with a soft-bristle toothbrush.
- Floss daily, slide the floss out rather than pulling upward around the crown.
- Avoid chewing ice, pens, or hard candy.
- Visit your dentist every six months for family dental care.
- If you notice discomfort or looseness, book a dental urgent care appointment immediately.
Crowns are an investment; proper care ensures that your restoration lasts for decades.
How Do You Know If a Dental Crown Needs Replacement?
Even the most durable crown won’t last forever. You may need a replacement if you notice:
- Pain or sensitivity around the crowned tooth
- Visible cracks or chips
- Receding gums or dark lines near the gumline
- Loose or unstable crown movement
- Decay under the crown detected by your dentist
If you have a crown for a broken tooth that’s over a decade old, it’s smart to have it checked during your routine visit.
Crown vs Veneers: Which Lasts Longer?
Many patients ask whether veneers last longer than crowns. Here’s a simple comparison:
| Feature | Dental Crown | Dental Veneer |
| Coverage | Entire tooth | Front surface only |
| Durability | 10–20 years | 10–15 years |
| Strength | High | Moderate |
| Purpose | Restore a damaged tooth | Enhance aesthetics |
| Cost | Moderate to high | Moderate |
If you’re considering veneers instead, explore permanent veneers or learn how much veneers cost before deciding.
What Happens If You Don’t Replace an Old Crown?
An old or damaged crown can lead to serious dental problems, such as:
- Tooth decay under the crown
- Cracked tooth structure
- Infection requiring endodontic therapy
- Difficulty chewing or speaking
Early detection prevents costly treatment later, such as full mouth rehabilitation.
Which Crown Material Is Best for Longevity?
If longevity is your top concern, here’s what dentists recommend:
- Zirconia: Extremely durable, resistant to wear, ideal for molars.
- Emax: High-strength ceramic offering both beauty and endurance.
- Gold: Longest-lasting but not aesthetic for front teeth.
Talk to your dentist about Emax veneers or crowns to find the best match for your smile and budget.
Expert Insight: How Technology Extends Crown Lifespan
Modern tools like CEREC, digital scanning, and CBCT imaging allow for ultra-precise fit and reduced human error. According to the Cleveland Clinic and Mayo Clinic, an accurate fit significantly reduces the risk of crown failure, gum irritation, and decay at the margins.
At our practice, we combine technology with advanced materials to help your crown last as long as possible.
FAQs About Dental Crown Longevity
How many years do dental crowns last?
On average, 10-15 years, but high-quality crowns can last 20+ years with good care.
Can a crown last a lifetime?
Rarely, but if it’s well-maintained and your oral hygiene is excellent, it might last several decades.
Do porcelain crowns break easily?
Porcelain is strong but more brittle than zirconia. Avoid chewing hard items to prevent chipping.
Can a crown be repaired instead of replaced?
Minor chips can sometimes be fixed with teeth bonding. However, large fractures usually need a full replacement.
