Getting a dental crown is a smart way to restore and protect a damaged tooth. But how long do dental crowns last, and is there anything you can do to keep them in great shape for longer?
Whether you’ve just had a crown placed or are considering one, understanding how to care for it properly can make a big difference to its lifespan and your long-term dental health.
Key Insights
- Most dental crowns last 5 to 20 years, depending on the material and how well you care for them.
- Porcelain crowns look natural but usually last 5 to 10 years, while metal or zirconia can last over 15 years.
- Dental implant crowns typically last 10 to 15 years, though the implant itself can last for life.
- Brushing, flossing, and avoiding hard foods help keep your crown in great shape.
- Teeth grinding can damage crowns. Ask your dentist about a nightguard if needed.
- A perfect fit from an experienced dentist gives your crown a better chance of lasting longer.
- If you notice pain, chips, looseness, or gum changes, your crown may need replacing.
How Long Do Dental Crowns and Dental Implant Crowns Last?
Most dental crowns last anywhere from 5 to 20 years, depending on the material used and how well you care for them. Here’s a general guide to average crown lifespans:
- Porcelain crowns: 5 to 10 years
- Ceramic or zirconia crowns: 10 to 15+ years
- Porcelain-fused-to-metal: 10 to 20 years
- Metal crowns: 15 to 20+ years
What about how long dental implant crowns last? The titanium post can last a lifetime with proper care. However, the implant crown that sits on top may need replacing every 10 to 15 years, especially with wear and tear over time.
Factors Affecting Longevity
Several key factors influence the durability of your crown, some of which you can control while others depend on your unique dental setup.
Crown Material and Tooth Location
Stronger materials like metal or zirconia tend to last longer, especially on back teeth that take the brunt of chewing. Porcelain looks natural but is better suited for front teeth, where bite pressure is lower.
Oral Hygiene Habits and Diet
Poor brushing, sugary snacks, or acidic drinks can wear down the crown or cause decay underneath it. Daily brushing, flossing, and regular dental checkups all contribute to better crown longevity.
Teeth Grinding or Clenching
If you grind or clench at night, the pressure can chip or crack your crown. A nightguard from your dentist can help protect it while you sleep.
Fit and Placement Accuracy
An accurately fitted crown from an experienced family dentist will naturally last longer and be less prone to complications like looseness or gum irritation.
Maintenance and Regular Checkups
Like natural teeth, crowns need ongoing care. Visiting your dentist for regular cleanings helps detect early signs of wear, decay, or other issues.
Signs Your Dental Crown May Need Replacing
If your crown is nearing the end of its life, you might notice:
- Sensitivity or pain when chewing
- Visible cracks or chips
- Looseness or movement
- Gum irritation or receding gums around the crown
- A dark line at the gumline (for porcelain-fused-to-metal crowns)
If you notice any of these signs, your crown may need replacing. Don’t wait – early action can prevent more serious problems.
Crown Dental Care Tips to Extend Lifespan
To get the most from your crown, follow these tips:
- Brush twice daily with a soft-bristle toothbrush
- Floss gently around the crown
- Avoid chewing ice, hard lollies, or using your teeth as tools
- Wear a nightguard if you grind your teeth
- Book regular checkups with your family dentist
