How Long Does a Dental Bridge Last?

Most dental bridges can last 5 to 15 years, but with good care, they can remain strong for 20 years or more. In this guide, you’ll learn what affects a bridge’s lifespan and how to make yours last longer.

What Affects Dental Bridge Longevity?

Several factors work together to determine how long do dental bridge lasts, including the type of bridge, materials used, placement location, daily care, and the health of supporting teeth and gums.

Type of Dental Bridge and Materials

The kind of bridge you choose and what it’s made from directly impacts how long it will last. Here’s a comparison:

✅ Summary:

• Fixed bridges are the most common and are cemented to neighboring teeth.

• Implant-supported bridges last the longest thanks to their strong foundation in the jawbone.

• Removable bridges are easier to clean but typically wear out faster.

Your dentist will help choose the best material and type based on your bite, budget, and overall oral health.

Placement in the Mouth

Dental bridges placed at the front of the mouth typically last longer due to less chewing pressure.

In contrast, bridges on back teeth absorb more bite force and may wear faster—especially if you grind or clench your teeth.

To prevent early damage, your dentist may recommend a night guard.

Health of Supporting Teeth

A dental bridge relies on healthy abutment teeth and gums for long-term stability.

If decay or gum disease affects these foundations, the bridge can loosen or fail.

Keeping your supporting teeth and gums healthy helps your bridge last longer.

Care for your dental bridge

Plaque around your bridge or nearby teeth can lead to decay, gum disease, or infection—common causes of dental bridge failure.

Practice good oral hygiene and visit your dentist regularly. These habits help your bridge last longer and reduce the risk of costly repairs or early replacement.

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 choosing how to replace missing teeth, think about more than just the cost. How long will each option last, and what care will it require over time?

Dental bridges and implants can both improve your smile. However, they differ in how long they last, how much upkeep they need, and their long-term worth.

In general, dental implants last longer than bridges. Most dental bridges last 5 to 15 years. In contrast, implants can last 20 years or more.

 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 implants with the function of bridges, offering the best of both worlds for many patients.

How to extend the lifespan of a dental bridge?

1. Maintain Excellent Daily Oral Hygiene

Brush 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 bridge and supporting teeth.

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. Visit Your Dentist Every 6 Months

Professional cleanings remove the buildup your toothbrush can’t reach. Regular check-ups help detect early wear, gum issues, or minor fractures before they turn into 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 gums strong. Don’t skip treatment for gum inflammation or decay in nearby teeth—your bridge relies on them for support.

✅ Summary: Consistent home care + regular dental visits + healthy habits = a dental bridge that may last 5–15 years or more.
