How Long does a 3-unit Dental Bridge Last Compared to an Implant?

Contact Us

When comparing the longevity of a 3-unit dental bridge to a dental implant, there is a significant difference in expected lifespan:

  • Dental Bridge Lifespan: A typical dental bridge is expected to last between 5 and 15 years. While it is a reliable restoration, its longevity is often limited because the supporting natural teeth remain susceptible to decay or structural fatigue over time.
  • Dental Implant Lifespan: Dental implants offer superior durability, with a success rate exceeding 95% over ten years. With proper oral hygiene and regular check-ups, a titanium implant can last 20 years or more, and often has the potential to remain functional for a lifetime.

Key factors affecting these timelines include:

  1. Osseointegration: Implants fuse directly with the jawbone, creating a stable foundation that preserves bone health, whereas bridges do not stimulate the bone.
  2. Impact on Adjacent Teeth: Bridges require the grinding down of neighboring healthy teeth, which can compromise their long-term health. Implants are independent units that do not affect surrounding teeth.
  3. Maintenance: While both require care, bridges can be more difficult to clean under the pontic, whereas implants are maintained much like natural teeth.
