Dental bridges are a common restorative solution used to replace one or more missing teeth. They “bridge” the gap between healthy teeth, restoring function and appearance. While dental bridges are not permanent, they are designed to be a long-term solution with proper care. Understanding the lifespan of dental bridges, including the factors that affect their longevity and how to maintain them, is key to getting the most value from this dental investment.
Average Lifespan of Dental Bridges
On average, a dental bridge can last 5 to 15 years, with some lasting even longer. The wide range in lifespan is due to several variables, including the type of bridge, the materials used, the patient’s oral hygiene, and overall dental health.
Traditional bridges (those anchored to natural teeth with crowns) tend to last a decade or more if the surrounding teeth and gums remain healthy. Implant-supported bridges, which are anchored by dental implants instead of natural teeth, may have even greater longevity of 30 or more years because they do not rely on neighboring teeth for support.
Factors That Influence Longevity
Several key factors impact how long a dental bridge lasts:
- Oral hygiene: Just like natural teeth, bridges require regular brushing and flossing. Poor oral hygiene can lead to decay in the abutment teeth (the teeth supporting the bridge) and gum disease, both of which can undermine the bridge’s stability.
- Material: Dental bridges can be made from various materials, including porcelain, ceramic, metal alloys, or a combination. Porcelain fused to metal bridges are common, offering strength and a natural look. All-metal bridges typically last longer but may be less aesthetically pleasing.
- Diet and habits: Chewing on hard foods, ice, or non-food objects can damage or wear down a bridge prematurely. Teeth grinding (bruxism) is another risk factor that can shorten a bridge’s life.
- Dental visits: Regular checkups and professional cleanings allow a dentist to monitor the bridge and surrounding teeth for any signs of wear, decay, or gum disease.
- Proper fit and installation: The skill of the dentist and the quality of the installation also play a significant role in determining how long the bridge will last. Seek out a dentist with experience and the proper credentials!
How to Prolong the Life of a Dental Bridge
To ensure the longest possible lifespan for a dental bridge, patients should:
- Brush twice daily and floss.
- Use an antibacterial mouthwash to reduce plaque and bacteria.
- Avoid hard or sticky foods that may stress the bridge.
- Visit the dentist twice a year for cleanings and checkups.
- Address any signs of discomfort, shifting, or damage immediately.
Dental bridges are a reliable and effective way to restore missing teeth, often providing many years of function and aesthetic benefit. With good oral hygiene, regular dental care, and mindful habits, many patients enjoy their bridges for well over a decade.
