How Long Do Dental Bridges Last? Factors That Influence Their Lifespan
If you’re missing one or more teeth, a dental bridge is a trusted way to restore your smile. But before starting treatment, most patients ask: how long do dental bridges last? The answer depends on the type of bridge, your oral health, and how well you care for it. This guide explains everything you need to know about dental bridge longevity, care, and alternatives – so you can make an informed decision.
What Is a Dental Bridge?
A dental bridge is a fixed dental restoration that fills the gap left by missing teeth. It’s made up of:
- Crowns – placed on the teeth adjacent to the gap for support
- Pontic – the artificial tooth that replaces the missing one
By restoring your bite and appearance, bridges prevent surrounding teeth from drifting, improve chewing and speech, and help maintain your facial structure.

Types of Dental Bridges
Not all bridges are the same. The type recommended depends on your needs:
- Traditional Bridge
- Involves two crowns on either side of the gap with a pontic in between.
- Most common type, suited when healthy adjacent teeth are available.
- Cantilever Bridge
- Supported by only one crown instead of two.
- Less common and usually used in areas with less chewing pressure.
- Maryland Bridge
- Uses a metal or porcelain framework bonded to the back of adjacent teeth instead of crowns.
- More conservative but less durable than traditional bridges.
- Implant-Supported Bridge
- Anchored by dental implants rather than natural teeth.
- Provides excellent stability and can last longer than traditional bridges.
Average Lifespan of Dental Bridges
On average, dental bridges last between 5 to 15 years. With excellent oral hygiene and regular dental visits, many last beyond 15 years – and in some cases, over 20.
Implant-supported bridges often last longer than tooth-supported bridges because implants integrate with the jawbone, reducing the risk of decay or failure in supporting teeth.
Factors That Affect Bridge Longevity
Several factors influence how long your dental bridge will last:
- Oral Hygiene: Bridges rely on the health of supporting teeth and gums. Plaque build-up, gum disease, or untreated decay can shorten their lifespan.
- Material Choice:
- Porcelain fused to metal bridges are durable but may show a dark line at the gum over time.
- All-ceramic or zirconia bridges offer excellent aesthetics and strength.
- Metal bridges are extremely durable but less natural-looking.
- Location in the Mouth: Bridges at the back of the mouth face more chewing pressure, which can lead to faster wear.
- Habits and Lifestyle: Smoking, teeth grinding, or chewing hard objects like ice can all reduce the lifespan of a bridge.
- Professional Care: Regular dental checkups allow your dentist to monitor the health of supporting teeth and gums, detect issues early, and maintain your bridge.
Caring for Your Dental Bridge
Looking after your bridge properly can extend its lifespan:
- Brush twice a day with fluoride toothpaste
- Floss daily using floss threaders or interdental brushes to clean under the pontic
- Use antibacterial mouthwash if recommended by your dentist
- Avoid chewing very hard foods that could damage the bridge
- Visit your dentist for routine checkups and professional cleaning
Bridges vs Implants: Which Lasts Longer?
A common comparison is between dental bridges and dental implants:
- Dental Bridges
- Average lifespan: 5-15 years
- Less invasive and quicker to fit
- More affordable upfront
- Relies on neighbouring teeth for support
- Dental Implants
- Average lifespan: 15-30 years or more (the implant post can last a lifetime)
- Helps preserve bone and doesn’t involve adjacent teeth
- Higher upfront cost and requires surgery
- Longer treatment timeline

Replacement and Cost Considerations
Over time, bridges may need replacement due to wear, gum changes, or damage. The replacement process is straightforward but requires professional assessment.
Costs vary depending on the type of bridge and material used, but in Australia, you can generally expect:
- Traditional or cantilever bridges: $3,000-$5,000
- Maryland bridges: $1,500-$3,500
- Implant-supported bridges: $5,000+, depending on the number of implants needed
While bridges are an investment, they offer significant functional and cosmetic benefits that improve daily life.
Common Questions About Dental Bridges
Can a bridge last a lifetime?
While rare, a bridge can last more than 20 years with exceptional care, but most need replacement at some stage.
Do bridges decay?
The bridge itself doesn’t decay, but the supporting teeth underneath the crowns can if not cleaned properly.
Is a bridge painful to get?
The procedure is not painful, as it’s performed under local anaesthetic. Some mild sensitivity is normal afterwards.
Do I still need checkups with a bridge?
Yes – regular visits ensure the supporting teeth and gums stay healthy and extend the life of your bridge.
Final Thoughts
So, how long do dental bridges last? The answer is usually 5 to 15 years, but with excellent care, they can last much longer. By maintaining good oral hygiene, avoiding damaging habits, and attending regular checkups, you can extend their lifespan significantly.
