How Long Does a Dental Bridge Last? A Comprehensive Guide for USA Patients


Dental Bridge

Dental bridges are a popular and effective solution for replacing missing teeth and restoring your smile. If you’re considering a dental bridge, one of the top questions on your mind is likely “How long will it last?” In this in-depth guide, we’ll explore the lifespan of dental bridges, factors that influence their longevity, and expert tips to make your bridge last as long as possible. As a leading dental practice serving patients across the USA, Xhaowen Dental is here to provide you with the most up-to-date and reliable information.

Understanding Dental Bridges

A dental bridge is a custom-made restoration designed to “bridge” the gap created by one or more missing teeth. It consists of one or more artificial teeth (called pontics) held in place by dental crowns attached to the natural teeth on either side of the gap (called abutment teeth). Bridges are fixed in place and can only be removed by a dentist.

Dental bridges offer several key benefits:

  • Restore your smile and facial appearance
  • Improve chewing and speaking ability
  • Maintain the shape of your face
  • Prevent remaining teeth from shifting out of position
  • Upgrade from a removable partial denture to a permanent dental appliance

Types of Dental Bridges

There are four main types of dental bridges:

  1. Traditional Bridges – The most common type, involving creating a crown for the tooth or implant on either side of the missing tooth, with a pontic in between.
  2. Cantilever Bridges – Used when there are adjacent teeth on only one side of the missing tooth or teeth. This is not very common anymore and is not recommended in the back of the mouth where it can put too much force on other teeth.
  3. Maryland Bonded Bridges – Made of porcelain, porcelain fused to metal, or plastic teeth and gums supported by a metal or porcelain framework. Metal or porcelain wings often on just one side of the bridge are bonded to your existing teeth.
  4. Implant-Supported Bridges – Dental implants are used instead of crowns or frameworks to anchor the bridge in place. This is considered the strongest and most stable system.

Your dentist can recommend the best type of dental bridge for your particular case. Factors influencing this choice include the location of the missing tooth (or teeth), the health and strength of the abutment teeth, and your budget.

Lifespan of Dental Bridges

On average, dental bridges last five to seven years. With good oral hygiene and regular checkups, it is not unusual for them to last over 10 years or even a lifetime in some cases. However, the longevity of your dental bridge depends on various factors.

Factors that influence how long a dental bridge lasts include:

  • Oral hygiene habits – Brushing twice a day, flossing daily, and using an antiseptic mouthwash can significantly extend the life of your bridge.
  • Lifestyle and dietary habits – Avoiding hard and sticky foods, not chewing on ice or other hard objects, and wearing a night guard if you grind your teeth can protect your bridge from damage. Smoking and heavy alcohol use can also negatively impact your oral health.
  • Dental bridge material – Bridges made of high-quality materials like gold alloys, porcelain fused to metal, or zirconia tend to last longer than all-porcelain or all-resin bridges.
  • Abutment teeth health – The natural teeth supporting the bridge must be strong and healthy. Bridges can fail more quickly if the surrounding teeth and gums are compromised by decay or gum disease.
  • Wear and tear – Bridges in high-stress areas like the back molars undergo more wear and tear from chewing forces. Front tooth bridges typically last longer.
  • Oral health conditions – Certain medical conditions like diabetes, osteoporosis, and immune system disorders can impact oral health and potentially shorten the lifespan of dental restorations.
  • Regular dental care – Seeing your dentist regularly for checkups and professional cleanings is crucial for maintaining your bridge and overall oral health. Your dentist can detect and address any early signs of problems.

Extending the Lifespan of Your Dental Bridge

With proper care and maintenance, you can maximize the longevity of your dental bridge. Here are some expert tips:

  1. Practice good oral hygiene – Brush twice daily with a soft-bristled toothbrush and fluoride toothpaste. Floss at least once a day, making sure to clean under and around the bridge. Use an antiseptic mouthwash to kill bacteria.
  2. Eat a tooth-friendly diet – Avoid hard, crunchy, or sticky foods that can damage or dislodge your bridge. Cut up foods like apples and carrots into bite-size pieces. Limit sugary and acidic foods and drinks.
  3. Don’t use your teeth as tools – Avoid habits like chewing on pens, fingernails, or using your teeth to open packages, as this can put undue stress on your bridge.
  4. Wear a night guard – If you grind your teeth at night, ask your dentist about a custom night guard to protect your bridge and natural teeth from excessive wear.
  5. Address dental problems early – If you notice any signs of trouble with your bridge or surrounding teeth, such as pain, swelling, or looseness, see your dentist right away. Prompt treatment can prevent minor issues from turning into major problems.
  6. See your dentist regularly – Schedule regular dental checkups and cleanings every six months, or more often if recommended by your dentist. This allows your dentist to closely monitor your bridge and address any potential issues early on.

Dental Bridge vs. Implant: Which Lasts Longer?

When it comes to replacing missing teeth, the main alternatives to dental bridges are partial dentures and dental implants. Partial dentures are removable appliances that rest on the gums and are held in place by clasps that attach to the natural teeth. They tend to be the least expensive option upfront but may need to be replaced every 5-7 years.

Dental implants, on the other hand, are titanium posts surgically placed in the jawbone to act as artificial tooth roots. A crown is then attached to the top of the implant. Implants are the longest-lasting tooth replacement option, with a lifespan of 15-20 years or more. They are also the most expensive option, often costing several thousand dollars per tooth.

Here’s a comparison of key factors between dental bridges and implants:

FactorDental BridgeDental Implant
Lifespan5-15 years15-20+ years
Cost$1,500 – $5,000 per tooth$3,000 – $6,000 per tooth
ProcedureNon-surgical; requires 2-3 visitsSurgical; requires multiple visits over several months
Bone densityDoes not prevent bone lossStimulates bone growth
AestheticsLooks natural; metal clasps may be visibleLooks and feels like a natural tooth
MaintenanceBrush, floss, regular checkupsBrush, floss, regular checkups

Ultimately, the best option for you depends on factors like your oral health, budget, and personal preferences. Your dentist can help you weigh the pros and cons and determine the most suitable solution for your unique case.

Common Reasons for Dental Bridge Failure

Even with the best care, dental bridges can sometimes fail prematurely. Common reasons include:

  • Decay in the abutment teeth – If the natural teeth supporting the bridge develop cavities, this can compromise the stability of the bridge.
  • Gum disease – Periodontal disease can cause the gums and bone supporting the bridge to deteriorate, leading to bridge failure.
  • Structural damage – Bridges can chip, crack, or break due to excessive biting forces, trauma, or wear and tear over time.
  • Poor fit – If a bridge is not properly fitted or cemented, it can come loose or fall out.

Regular dental checkups are essential for detecting and addressing these issues early on before they lead to bridge failure.


Dental bridges are a reliable, long-lasting solution for replacing missing teeth and restoring your smile. With proper care and maintenance, a dental bridge can last anywhere from 5-15 years or even longer. Factors like oral hygiene, diet, bridge material, and regular dental visits all play a role in extending the lifespan of your bridge.
