How Long Do Dental Crowns and Bridges Last?

Dental crowns and bridges are effective restorative treatments that help protect damaged teeth, restore chewing function, and enhance your overall smile. Whether you have a tooth that needs reinforcement or a missing tooth that needs to be replaced, these restorations can play an important role in maintaining your oral health. But you may be wondering: How long do dental crowns and bridges last? At Woodfield Dental in London, Ontario, we design crowns and bridges with quality materials and precise placement to ensure long-lasting results. However, the lifespan of these restorations depends on several factors, including care, oral habits, and overall dental health.

Average Lifespan of Dental Crowns

Dental crowns typically last 10 to 15 years. However, with excellent care, many crowns can last 20 years or longer. Crowns are made from durable materials such as porcelain, ceramic, zirconia, or porcelain fused to metal. These materials are designed to withstand everyday chewing and biting forces while maintaining a natural appearance.

Average Lifespan of Dental Bridges

Dental bridges generally last 10 to 15 years, but some can remain functional for 20+ years when properly maintained. A bridge replaces one or more missing teeth by anchoring to the surrounding natural teeth or implants. Because bridges rely on supporting teeth, the health of those teeth and gums is critical for the longevity of the restoration.

Factors That Affect the Lifespan of Crowns and Bridges

1. Oral Hygiene Habits

Brushing twice daily and flossing daily helps prevent decay around the restoration and supports gum health.

2. Diet and Chewing Behaviors

Chewing on hard substances like ice, popcorn kernels, or pens can damage both crowns and bridges.

3. Teeth Grinding (Bruxism)

Grinding can place excessive pressure on crowns and bridges. If you grind your teeth, a nightguard can protect your restoration.

4. Gum Health

Healthy gums support stable and long-lasting restorations. Regular cleanings help prevent gum disease, which can weaken the foundation of crowns and bridges.

5. Dental Exams and Professional Care

Regular checkups allow us to monitor the condition of your restoration and address potential issues early.

Signs Your Crown or Bridge May Need to Be Replaced

Over time, crowns and bridges may experience natural wear. Signs to watch for include:

• Loosening or shifting 
• Sensitivity to hot or cold 
• Visible cracks or chips 
• Receding gums around the restoration 
• Pain when chewing 

If you notice any of these, we may recommend evaluating the crown or bridge to ensure continued comfort and function.

How to Help Crowns and Bridges Last Longer

To maximize the lifespan of your restoration:

• Brush and floss daily — especially around the gumline 
• Avoid using your teeth as tools to open packages 
• Limit very sticky or extremely hard foods 
• Wear a nightguard if you grind your teeth 
• Keep up with dental cleanings and exams every 6 months 

These habits help maintain both your restoration and your overall oral health.
