A dental bridge is a common way to replace one or more missing teeth, but is it permanent? This is a question many patients ask when choosing their options. While dental bridges are made to last for years, their longevity depends on how well you care for them, the type of bridge used, and your overall oral health. Discover what to expect from the dental bridge procedure at Auburn Bay Dental and how to make it last.
Key Takeaways
- Dental bridges are not permanent and typically last between 5 and 15 years.
- Different types, traditional, cantilever, Maryland, and implant-supported, vary in durability and suitability.
- Proper oral hygiene, regular dental visits, and avoiding harmful habits can extend the lifespan of your bridge.
Do Dental Bridges Last Forever?
Many people assume that bridges are permanent, but this isn’t entirely true. They are long-lasting but not lifelong. Studies show that approximately 97% of dental bridges remain functional beyond five years.
Further research reveals that approximately 74% remain intact after 15 years. This indicates that bridges generally offer excellent durability over time.
With proper oral hygiene and consistent dental checkups, some can even last well beyond 15 years.

Which Types of Dental Bridges Last Longer?
Bridges are used to replace missing teeth by connecting artificial teeth to nearby natural teeth or implants. However, not all offer the same durability. The type you choose can affect how long it lasts and how well it functions over time.
Traditional Bridge
Lifespan: 10-15 years
This type of bridge uses remaining teeth on either side of the gap as anchors to support one or more artificial teeth. Crowns are placed over these healthy teeth, known as abutment teeth, to hold the bridge securely in place.
This type is one of the most widely used options to replace missing teeth, especially when the remaining teeth are strong and stable. They provide a durable solution for everyday functions like chewing and biting.
Cantilever Dental Bridge
Lifespan: 5-10 years
A suitable choice when there’s only one healthy tooth next to the gap left by a missing tooth or when there aren’t two strong abutment teeth available to support a traditional bridge. The pontic (replacement tooth) is placed in the gap and secured to the remaining tooth on just one side.
When supported by a dental implant, the cantilever type can achieve excellent long-term outcomes. A 2010 study reported a 5-year success rate of 94.3% for implant-supported fixed prosthetics used to replace a single missing tooth.
Maryland Dental Bridges (Resin-Bonded)
Lifespan: 5-8 years
Features a metal or ceramic framework with small “wings” that are attached to the back of the adjacent teeth. This type is considered more conservative since it doesn’t rely on crowns for support.
They’re a good choice for replacing missing front teeth when the surrounding teeth are healthy and strong. However, they’re generally not recommended for back teeth like molars.
Implant-Supported Bridges
Lifespan: 15-25 years
Unlike other types that rely on nearby teeth for support, this option is anchored by implants surgically placed into the jawbone. It offers exceptional stability and is useful when multiple teeth in a row are missing or when the surrounding teeth aren’t strong enough to support a traditional dental bridge. It also helps preserve bone density and serves as a long-lasting, reliable solution for tooth replacement.
Extend the Lifespan of Your Bridges
Unlike dentures, these dental appliances cannot be removed by the wearer. However, they do have a limited lifespan.
On average, they can last between five and seven years, but with proper maintenance, some can last over fifteen years.
- Brush and floss at least twice daily
- Schedule regular checkups and professional cleanings
- Avoid chewy or sticky foods
- Wearing a night guard helps prevent teeth grinding
- Maintain a balanced diet that’s low in sugar and acidic foods
Signs You Need To Replace Your Dental Appliance
Eventually, the question shifts from how long a bridge lasts to knowing when it’s time to replace it. This is a normal part of dental care that everyone experiences sooner or later. You should consider a replacement if you notice the following:
- Visible cracks or chips
- Gum recession
- Discomfort or irritation
- No longer fit properly
Bridges Last Longer But Not “Permanently”
While these dental appliances may not be truly permanent, they can offer a strong, stable, and long-lasting solution for replacing missing teeth. The type of bridge you choose, your daily oral hygiene habits, and regular dental checkups all affect how long your bridge will last.
With proper care, many can serve you well for over a decade, and in some cases, even longer. If you’re considering a bridge or wondering whether your current one needs replacement, our nearby dentist at Auburn Bay Dental can guide you through every step of the process.

Frequently Asked Questions
Which is better, an implant or a bridge?
A bridge is a practical and dependable option for restoring your smile and avoiding further dental issues. In many cases, it’s preferred over an implant because it doesn’t require surgery (except for implant-supported options) and involves a shorter treatment and healing time.
Are bridges stronger in the front or back of the mouth?
Back. Front dental appliances may offer good durability, they may wear down more quickly over time compared to stronger materials. A Maryland bridge (also known as a resin-bonded bridge) is a common option.
Do temporary bridges exist?
Yes. A temporary bridge is a part of the process before placing a permanent one. It protects the exposed dentin and prevents bacteria and food from entering the prepared teeth.
