Dental bridges are a reliable way to replace missing teeth, restoring both your smile and your ability to chew comfortably. With proper care, a bridge can last more than a decade—sometimes as long as 15 years. However, like any dental restoration, bridges aren’t indestructible. Knowing the common reasons a dental bridge might fail can help you take steps to extend its lifespan.
Poor Oral Hygiene
The most common reason dental bridges fail is poor oral hygiene. Bridges depend on the health of the surrounding teeth and gums. If plaque builds up, it can lead to decay or gum disease under the crowns that anchor the bridge. Once these supporting teeth are weakened, the entire bridge is at risk. Daily brushing, flossing, and regular dental visits are crucial for protecting both your natural teeth and your bridge.
Weak or Damaged Supporting Teeth
A bridge relies on the teeth on either side of the gap for support. If those teeth are already weak or become damaged over time, the bridge may loosen or fail altogether. Your dentist will evaluate the strength of the surrounding teeth before placing a bridge, but ongoing dental care is necessary to keep them strong.
Bite Problems or Misalignment
If your bite is uneven or your teeth don’t come together properly, excessive pressure can be placed on your bridge. Over time, this extra stress can cause the bridge to crack, loosen, or fail. Adjustments by your dentist can help balance your bite and protect your restoration.
Normal Wear and Tear
Even with good care, dental bridges are subject to daily wear. Chewing hard foods, grinding your teeth, or using your teeth to open packages can all shorten the life of a bridge. Over time, small cracks or loosening may occur, requiring repair or replacement.
Poor Fit or Placement
Sometimes, bridge failure is linked to how the restoration was made or placed. If the bridge doesn’t fit properly, bacteria can slip underneath, leading to decay or gum issues. Choosing an experienced dentist helps reduce the risk of improper placement and ensures the bridge is designed to function correctly.
A dental bridge can last many years, but only if it’s cared for properly and supported by strong, healthy teeth.
