Missing a tooth can shake your confidence, and while procedures such as a dental bridge are a trusted fix, one question lingers in every patient’s mind: How long will they really last?
The truth is, dental bridges are a durable, long-term solution, but their lifespan depends on how well they’re made, placed, and maintained.
In this comprehensive guide, we’ll walk you through everything you need to know: how long does a dental bridge last, what factors influence their durability, tips to extend their life, warning signs of failure, and when it might be time for a replacement.
What is a Dental Bridge?
A dental bridge is a fixed prosthetic device that “bridges” the gap created by one or more missing teeth. It typically consists of:
- Abutment teeth: The supporting teeth or implants on either side of the gap
- Pontics: The artificial tooth or teeth that fill in the space
Dental bridges restore functionality, help maintain facial structure, prevent neighbouring teeth from shifting, and improve your smile. But how long do dental bridges last?
Average Lifespan of a Dental Bridge
The average dental bridge lasts between 5 to 12 years, depending on the type of bridge and how well it’s maintained.
The American Dental Association (ADA) reports that well-maintained dental bridges last longer. They can last up to 10 to 15 years.
Types of Dental Bridges and Their Durability
Choosing the right dental bridge is crucial, not just for appearance and function, but also for durability. Each type of bridge has its own strengths, limitations, and expected lifespan based on design and materials used.
Here’s a breakdown of the most common types of dental bridges and how durable they are:
Traditional Dental Bridge
A traditional bridge is crafted with a fake tooth in the middle, secured by porcelain wings on each side of a real tooth. Such bridges usually last for about seven years, but sometimes, if the nearby teeth develop problems, you might have to replace them earlier.
Cantilever Dental Bridge & Maryland Dental Bridge
A dental bridge using just one tooth for support (called a cantilever) or a metal framework (known as a Maryland) usually lasts about five to seven years.
Implant-Supported Bridge
Implant-supported dental bridges can stay strong much longer than regular ones. If you take good care of them and keep them clean, the implants supporting the bridge can last your whole life.
The table below will illustrate how these types of bridges differ from one another:
| Type of Dental Bridge | Typical Lifespan | Durability |
| Traditional Fixed Bridge | 10–15 years | Very durable |
| Cantilever Bridge | 5–10 years | Less support, lower longevity |
| Maryland (Resin-Bonded) Bridge | 5–10 years | Conservative, but may loosen |
| Implant-Supported Bridge | 15–25 years | Highest stability and longevity |
Factors that Affect How Long a Dental Bridge Lasts
The following are some factors that affect how long dental bridges last:
-
Material Used
- Porcelain-fused-to-metal (PFM) bridges offer strength and aesthetics.
- All-ceramic or zirconia bridges appear more natural but may wear down more quickly.
- Metal alloy bridges are extremely strong and suitable for molars.
-
Oral Hygiene
A major cause of bridge failure is decay of the natural teeth under the crowns. Poor brushing and flossing habits can drastically shorten a bridge’s lifespan.
-
Diet & Habits
Biting hard foods, chewing ice, or using your teeth as tools can stress your bridge. Similarly, grinding or clenching teeth (bruxism) without protection can cause it to weaken over time.
-
Overall Oral Health
Gum disease, bone loss, or infections in the supporting teeth or implants can compromise your bridge.
-
Regular Dental Visits
Routine checkups help detect minor issues before they become more serious. Your dentist can assess the fit and function of your bridge and recommend maintenance or repairs when needed.
Warning Signs Your Dental Bridge May Be Failing
Even the most well-maintained bridge can wear out over time. Be on the lookout for these red flags:
- Pain, sensitivity, or discomfort near the bridge
- Loose or shifting bridge
- Chipped or cracked pontics
- Receding gums or bleeding near the abutment teeth
- Difficulty chewing or speaking clearly
If you notice any of these symptoms, consult your dentist promptly to avoid further complications.
How to Extend the Life of Your Dental Bridge?
The following best practices can help extend the durability of your dental bridge:
Daily Oral Hygiene
- Brush your teeth twice a day using a soft-bristled toothbrush.
- Floss carefully under the bridge using a floss threader or water flosser.
- Use an antimicrobial mouthwash to prevent plaque and gum disease.
Night Protection
If you grind your teeth, wearing a custom night guard can protect both your bridge and natural teeth from premature wear.
Dietary Choices
Avoid chewing hard objects, sticky candies, or biting into ice. These habits can weaken or damage your bridge over time.
Routine Dental Checkups
Visit your dentist every six months for a professional cleaning and evaluation of your bridge’s condition.
Is a Dental Bridge Worth It Long-Term?
A dental bridge may cost anywhere from $2,000 to $5,000, depending on the type, number of missing teeth, and materials used. When maintained properly, bridges are a cost-effective solution, offering long-term benefits for both oral function and aesthetics.
Ask your dentist about payment plans or dental insurance coverage that may reduce your out-of-pocket costs.
Final Thoughts
Dental bridges are the most effective solution for missing teeth. However, it is important to understand how long dental bridges last and what care is needed to ensure they don’t degrade prematurely.
However, if you suspect any issues, it is advisable to consult your oral healthcare provider for maintenance or replacement of your dental bridges.

Frequently Asked Questions (FAQs)
Q1. Can a dental bridge be repaired instead of replaced?
Yes, in some cases, minor repairs can extend the life of your bridge. However, severe damage or decay may require full replacement.
Q2. How do I know if I need a bridge replacement?
If your bridge feels loose, causes discomfort, or shows visible damage, it’s time to consult your dentist.
Q3. Are dental implants a better option?
Implants generally last longer (20+ years) and don’t rely on adjacent teeth, but they’re also more expensive and involve surgery. Your dentist can help you compare both options.
