How Long Does a Dental Bridge Last?

Most dental bridges last about 5 to 15 years. With proper care, some bridges can last for 20 years or more. However, the exact lifespan of a bridge depends on several factors, including the type of bridge, the material used, and your daily oral hygiene habits.

As shown in the illustration, the lifespan varies by bridge type: Traditional bridges (5–10 years), Implant-supported (15+ years), Cantilever bridges (5–7 years), and Maryland bridges (5–10 years).

In this guide, you’ll learn the key factors that affect how long dental bridges last and get five simple, expert-approved tips to extend the lifespan of your dental bridge.

What Affects Dental Bridge Longevity?

Type of Dental Bridge and Materials

The kind of bridge you choose and the material used to make it directly impact how long it will last. Here’s a comparison of the different types of dental bridges:

Your dentist will help you select the most suitable bridge type and material based on your specific needs, budget, and overall dental health.

Placement in the Mouth

Where your dentist places your bridge plays a key role in its longevity. A bridge replacing a front tooth faces less chewing pressure and is likely to last longer.

However, your back teeth do the heavy work, absorbing the full force of your bite. This causes bridges on back teeth to wear out more quickly, especially if you have a habit of grinding or clenching.

If you grind your teeth, talk to your dentist. They may recommend a night guard to protect your dental bridge from early damage.

The Health of the Supporting (Abutment) Teeth

Think of your supporting teeth—also known as adjacent teeth—as the foundation of a house. A dental bridge anchors to these natural teeth for stability and strength.

If this foundation becomes weak due to problems like decay or advanced gum disease, it can no longer support the bridge. This will cause the bridge to feel loose or fail, regardless of how well-made it is.

4. Daily Oral Hygiene and Plaque Control

Practicing good oral hygiene is another critical factor. Poor cleaning allows harmful plaque, a sticky film of bacteria, to build up along the gum line and at the edges of the bridge.

This buildup can lead to new cavities on the supporting teeth or infections in the gums, both of which are common reasons a dental bridge needs to be replaced.

Signs It Might Be Time for a Replacement

Cracks or Loosening

If you notice chips, visible cracks, or a loose feeling while chewing, the bridge may no longer fit properly. This can lead to further damage if not addressed.

Pain or Swelling

Pain, redness, or bleeding around the bridge could indicate gum inflammation or infection beneath the surface. Don’t ignore these symptoms – schedule a check-up right away.

Decay Under the Crown

Even though the dental crown is artificial, the natural teeth underneath can still develop decay. This weakens the support for the bridge and may require full replacement to prevent future issues.

Dental Bridge vs. Dental Implant: Which Lasts Longer?

When considering a dental bridge or other options to replace missing teeth, it’s important to think about more than just the cost. How long will each option last, and what care will it require over time?

Dental bridges and dental implants can both restore your smile. However, they differ in their average lifespan, maintenance needs, and long-term value.

In general, dental implants often last longer than bridges. Most dental bridges can last 5 to 15 years. In contrast, an implant can last a lifetime with proper care. A dental implant also helps prevent bone loss in the jaw, which a bridge does not.

If you’re looking for a long-term solution, especially as a younger patient, a dental implant may be the better investment. Here’s a quick comparison to help you decide:

If you’re considering your options, talk to your dentist about implant-supported bridges as well. These combine the stability of teeth or implants with the function of bridges, offering an excellent tooth replacement option for many patients.

How to extend the lifespan of a dental bridge?

As discussed in the factors above, the longevity of your bridge is largely in your hands. Here are five simple, expert-approved tips to help you get the most out of your dental bridge:

1. Practice Good Oral Hygiene

Brush and floss twice a day using a soft-bristle toothbrush and fluoride toothpaste. Floss daily, especially under the bridge, using floss threaders, interdental brushes, or a water flosser. This prevents plaque buildup around the supporting teeth and the bridge itself.

2. Avoid Chewy or Sticky Foods

Steer clear of caramels, gum, and hard candies. These can loosen, crack, or damage the bridge over time.

3. Schedule Regular Dental Check-ups

Professional cleanings remove the buildup your toothbrush can’t reach. Regular dental check-ups help your dentist detect early wear, gum issues, or minor fractures before they become bigger problems.

4. Wear a Night Guard If You Grind Your Teeth

Grinding (bruxism) puts excessive pressure on your bridge. A custom night guard protects both the bridge and your natural teeth.

5. Support Gum and Tooth Health

Eat a balanced diet rich in vitamins C and D to keep your teeth and gums strong. Don’t skip treatment for gum inflammation or decay in surrounding teeth; your bridge relies on them for support.

Frequently Asked Questions

How often should a dental bridge be checked?

You should have your dental bridge checked every 6 months during your regular dental checkups. These visits help your dentist catch early signs of wear or problems.

What happens if my dental bridge fails early?

Early failure usually happens when poor oral hygiene or pressure on the supporting teeth weakens the structure. Your dentist will examine the cause and recommend whether repair or replacement is best.

Which lasts longer, a dental bridge or a denture?

On average, a denture lasts 5 to 8 years, while fixed dental bridges are designed to last 10 to 15 years or more. Bridges also tend to feel more stable and natural in your mouth.

Does insurance cover the cost of replacing a dental bridge?

Coverage varies; some plans only pay to replace a dental bridge after five years or not at all. Check your policy to avoid surprise costs.

The cost to replace a bridge without insurance typically ranges from $2,000 to $5,000. Understanding your out-of-pocket costs can help you plan financially for future dental care.
