A dental bridge fills the gap left by one or more missing teeth, restoring your ability to chew, speak, and smile with confidence. When you invest in a bridge, you want to know how long it will last. The good news: with proper care, bridges commonly last 10–15 years—and many last 20 years or more. Lifespan depends on the quality of the work, your oral hygiene, and factors like your bite and habits. Here's what you need to know.
Typical Lifespan: 10–15 Years or More
Bridges are built to last. The national average is often cited at around 10 years, but many patients keep their bridges for 15–20 years or longer. The key is maintenance. Just like natural teeth, bridges need to be cleaned and cared for. The supporting teeth (abutments) are especially important—decay or gum disease around them can compromise the entire bridge.
What Affects How Long a Bridge Lasts?
- Oral hygiene — Brushing, flossing (including under the pontic with a floss threader or water flosser), and regular cleanings protect the abutment teeth and gums. Decay or periodontal disease can lead to bridge failure.
- The health of supporting teeth — Bridges rely on the teeth on either side. If those teeth are lost or severely damaged, the bridge fails. Keeping them healthy is essential.
- Bite forces — Grinding or clenching can stress a bridge. A night guard can help protect it.
- Quality of fit and materials — A well-made bridge that fits properly will last longer. Choosing an experienced dentist and quality materials matters.
- Diet and habits — Avoiding hard or sticky foods that could damage the bridge helps. Don't use your teeth as tools.
How to Care for Your Bridge
- Brush twice daily, including around and under the bridge
- Floss daily—use a floss threader or water flosser to clean under the pontic
- Visit your dentist for regular checkups and cleanings
- Wear a night guard if you grind or clench
- Avoid biting into extremely hard foods with the bridge
When Might a Bridge Need Replacement?
Replacement may be needed if:
- The abutment teeth develop decay or are lost
- The bridge becomes loose or the cement fails
- There's significant wear or damage to the bridge
- Gum disease affects the supporting teeth
Regular checkups help catch problems early—before they threaten the bridge.
The Bottom Line
With good care, a dental bridge can serve you well for a decade or more. Treat it like the valuable restoration it is—and it will reward you with years of function and confidence.
