How Long Do Dental Implants Last?
Implant survival rates, what causes the failures that do happen, and the maintenance habits that separate a ten-year implant from a thirty-year one.

The numbers
Long-term studies consistently place ten-year implant survival in the mid-to-high nineties percent range for healthy patients with adequate bone. Many implants placed in the 1980s remain in function today.
It is important to separate the two parts. The titanium fixture in the bone is the durable component. The crown on top is a restoration with a normal lifespan of roughly ten to fifteen years and may be replaced once or twice over the life of the implant.
Why implants fail when they fail
Early failure, within the first months, usually reflects a problem with integration: infection at placement, insufficient bone quality, excessive loading too soon, or heavy smoking, which measurably reduces success rates.
Late failure is most often peri-implantitis, an inflammatory process around the implant that destroys supporting bone. It behaves like gum disease and has the same principal cause: bacterial biofilm left undisturbed. Uncontrolled diabetes, a history of periodontitis, and untreated grinding all raise the risk.
What maintenance actually looks like
Implants do not decay, which sometimes creates false confidence. They still require daily cleaning under and around the crown with floss designed for implants, an interdental brush, or a water flosser.
Professional maintenance every three to six months with instruments appropriate for implant surfaces, plus periodic X-rays to monitor bone levels, catches problems while they are still reversible. A night guard is strongly advised if you grind.
Getting the foundation right
Success starts before surgery: three-dimensional imaging to map bone and nerve position, grafting where volume is inadequate, and guided placement so the implant sits where the final crown needs it.
Planned well and maintained consistently, an implant is the closest replacement to a natural tooth modern dentistry offers. Our dental implants page walks through each stage and the healing timeline.
