At the Center for Dental Excellence in Nashua, I’m often asked how long dental bridges last. The truth is, a dental bridge lifespan can vary significantly depending on the materials used, oral hygiene habits, and individual patient factors. On average, most dental bridges last between 10 to 15 years, though some can last much longer with proper care.

Understanding the expected longevity of your dental bridge helps you make informed decisions about your treatment and long-term oral health. This guide will walk you through the typical bridge durability, what affects tooth bridge longevity, and how to maximize the life of your restoration in Nashua’s unique environment.

What Is the Typical Lifespan of a Dental Bridge?

The typical dental bridge lifespan ranges from 5 to 15 years. With optimal care and professional maintenance, many bridges last well beyond that range.

As a dentist in Nashua, I’ve seen traditional bridges last 20 years or more in patients who maintain excellent oral hygiene and visit regularly for checkups. However, lifestyle habits, materials, and oral health all play a role in determining bridge durability.

Dental bridge lifespan: What to expect

• Porcelain-fused-to-metal bridges: Often last 10–15 years
• Zirconia bridges: Highly durable and can last 15–20 years
• Metal-only bridges: Less common, but may exceed 20 years in certain cases

Lifespan of a dental bridge vs other restorations

• Dental implants: Typically last 25+ years with proper care
• Dentures: Last 5–10 years but may require relining
• Crowns: Usually last 10–15 years

While implants tend to offer the longest-lasting results, a well-placed and maintained bridge remains a reliable solution for replacing missing teeth.

What Is the Average Dental Bridge Lifespan?

On average, the dental bridge lifespan is about 10 to 15 years. This estimate considers general usage, common wear and tear, and routine dental maintenance.

Average dental bridge lifespan based on materials

• Porcelain-fused-to-metal: A popular choice for its balance of strength and aesthetics, typically lasting 10–15 years.
• Zirconia: Known for its strength and biocompatibility, with average lifespans of 15+ years.
• Gold or metal alloy: Rarely used for front teeth due to appearance, but can last 20+ years in molars.

How long do dental bridges last with proper care? 

With excellent oral hygiene and regular checkups, I’ve seen many Nashua patients enjoy their bridges for nearly two decades. Key care factors include:

• Brushing twice a day with fluoride toothpaste
• Daily flossing, including under the bridge
• Avoiding excessive pressure from grinding or chewing ice
• Scheduling professional cleanings twice per year

We also recommend using a floss threader or interdental brush to clean underneath the pontic (the false tooth) to prevent plaque buildup that can shorten your bridge’s life.

What Affects the Lifespan of a Dental Bridge in Nashua?

Several factors influence tooth bridge longevity, including the patient’s oral hygiene, lifestyle, and the materials used. In Nashua, seasonal temperature changes and dietary habits can also play a minor role.

Common causes of bridge failure or wear

• Decay in abutment teeth: If the supporting teeth develop cavities or infections, the entire bridge may need to be removed.
• Gum disease: Periodontal issues can destabilize the teeth that hold the bridge.
• Poor bite alignment: Can cause uneven pressure and stress on the bridge.
• Accidents or trauma: Physical injury to the mouth can damage or loosen a bridge.

Role of oral hygiene and diet 

Proper brushing and flossing are essential to avoid decay and inflammation that compromise bridge durability. Avoiding hard foods (e.g., ice, popcorn kernels) and limiting sugary snacks also helps preserve the bridge.

Is the Lifespan of a Dental Implant Bridge Different?

Yes, dental implant bridges typically have a longer lifespan than traditional bridges. While traditional bridges rely on natural teeth for support, implant-supported bridges are anchored directly into the jawbone.

• Traditional bridge: 10–15 years average
• Implant-supported bridge: 15–25+ years

Implants are made from biocompatible titanium, which fuses with the bone and provides long-term stability. The bridge itself may need to be replaced due to wear, but the implants often remain intact for decades.

Pros and cons of implant-supported bridges

Pros:

• Longer lifespan
• Improved chewing function
• No damage to adjacent teeth

Cons:

• Higher initial cost
• Requires oral surgery
• Longer healing time

If you’re interested in implant-supported bridges for lasting tooth replacement, we’d be happy to discuss your eligibility during a consultation at our Nashua office.

How Can Nashua Patients Extend the Life of Their Dental Bridge?

To get the most out of your dental bridge, prevention is key. I recommend the following steps to all my Nashua patients to ensure maximum bridge durability.

At-home care tips to protect your bridge

• Use a soft-bristled toothbrush to avoid damaging the bridge’s surface
• Clean underneath the bridge daily using a floss threader or water flosser
• Wear a night guard if you grind your teeth while sleeping
• Avoid chewing hard objects like pens, ice, or fingernails

How often to visit your Nashua dentist for checkups 

Regular dental visits allow us to monitor the integrity of your bridge and the health of the supporting teeth. I typically recommend:

• Exams and cleanings every 6 months
• Annual x-rays to detect hidden issues under the bridge

When to consider replacing your bridge

You may need a replacement if you experience:

• Looseness or movement in the bridge
• Pain around the abutment teeth
• Gum recession or visible decay
• Visible wear, cracking, or discoloration

Knowing the signs of wear helps us act early and avoid more costly repairs down the line.

Common Questions About Dental Bridge Lifespan

Can a dental bridge last 30 years?

Yes, it’s possible for a dental bridge to last 30 years, especially if it’s well-made and maintained. While this isn’t typical, I’ve seen long-lasting results in patients with excellent oral health and habits.

Can teeth decay under a bridge?

Yes. Decay can occur if plaque builds up around the edges of the bridge, especially near the gumline. Regular flossing and cleanings help prevent this.

How often should a dental bridge be replaced?

Most bridges are replaced every 10 to 15 years. However, early replacement might be necessary if there’s structural damage or issues with the supporting teeth.

What is the downside of a bridge?

One limitation is that it requires grinding down healthy teeth for support. Also, if the underlying teeth fail, the bridge must be removed and replaced.

What happens to a dental bridge after 10 years?

Over time, a bridge may show signs of wear such as cracks or looseness. It’s essential to have it inspected routinely to catch early issues before they worsen.

Plan for a Long-Lasting Dental Bridge in Nashua

Understanding your dental bridge lifespan is essential to protecting your oral health and investment. Most bridges last 10 to 15 years, but with proper care and early intervention, many last much longer. Your habits, hygiene, and regular checkups are key to maximizing bridge durability.
