Implants vs. Bridges: Which Lasts Longer

When one or more teeth are lost, patients face a logical question: implants or bridges – which is better and which will last longer?
Both methods are widely used in dentistry, but there are fundamental differences between them that affect lifespan, comfort, and long-term oral health.
Let's break it down honestly and thoroughly.

What Are Implants and Bridges

Comparison between a dental implant and a dental bridge for missing tooth replacement

Dental Implants

An implant is an artificial root that is placed into the jawbone. A crown is attached to it, completely replacing the missing tooth – both functionally and aesthetically.

Dental Bridges

A bridge is a structure of several crowns that is fixed to adjacent teeth, which are prepared (ground down) beforehand. The bridge "spans" the missing tooth but doesn't replace its root.

Implants or bridges: comparing durability

Let's compare implants and bridges by key longevity criteria:

Criteria Implants Bridges
Average lifespan 20–30+ years 7–10 years
Impact on adjacent teeth None Grinding required
Bone preservation Yes No
Risk of retreatment Minimal Higher
Chewing sensation Like natural tooth Less natural

In terms of longevity, implants are significantly superior.

Why Implants Last Longer

Don't Burden Adjacent Teeth

An implant is a standalone structure. It doesn't depend on the condition of other teeth and doesn't overload them.

Prevent Bone Resorption

After tooth loss, the bone begins to deteriorate.An implant stimulates the bone like a natural root.

Easier to Maintain

Implants are cleaned like regular teeth, without complex areas under the bridge.

When Bridges May Be a Justified Choice

Bridges are sometimes appropriate if:

  • adjacent teeth already have large fillings or crowns
  • there are medical contraindications to implantation
  • a quick and more budget-friendly solution is needed

But it's important to understand: this is a compromise, not a long-term investment.

Financial Aspect: What's More Cost-Effective Over Time

At first glance, bridges are cheaper. But if you calculate for 15–20 years:

  • the bridge needs to be replaced 1–2 times
  • treatment of abutment teeth may be necessary
  • the risk of losing several teeth instead of one increases

Ultimately, implants often prove more cost-effective.

Frequently Asked Questions

Implants or bridges – which is more reliable?

Implants. They don't depend on other teeth and last longer.

Can you place a bridge after an implant?

Yes, in some cases a bridge is fixed on implants.

Is it painful to place an implant?

No. The procedure is performed under anesthesia and is well tolerated.

Conclusion

When comparing implants or bridges in terms of longevity, implantation is the clear winner.

It preserves bone, doesn't harm adjacent teeth, and provides a stable result for decades.

The final choice always depends on the clinical situation, but if possible – an implant is almost always the better option.
