How long do dental implants last?
A dental implant is a titanium (or zirconia) screw fused into the jawbone, and in a healthy, well-maintained patient it is designed to be a long-term — often lifelong — tooth replacement. The most useful single number comes from a systematic review of studies with at least 10 years of follow-up, which reported a pooled implant survival rate of about 94.6% at 10 years (Moraschini et al., 2015).1 In plain terms: of every 100 properly-placed implants in patients in structured follow-up, roughly 95 are still in place a decade later.
There is no fixed expiry date. Many implants placed in the 1970s and 1980s were still functioning decades later. But "the implant lasts" and "nothing on it ever needs attention" are not the same thing — and the difference matters when you are deciding whether to have one.
Survival versus success — the difference that matters
It helps to separate two ideas that sound alike. Survival means the implant is still physically in place. Success means the implant is in place and healthy and functioning, with no inflammation or progressive bone loss around it. The same 10-year review reported a pooled success rate of about 89.7% — lower than the survival figure, because some implants survive while no longer being fully healthy (Moraschini et al., 2015).1
The reason success runs behind survival is peri-implantitis — inflammatory bone loss around an implant, the implant equivalent of gum disease. A large Swedish population study found that nine years after implant therapy, 45% of patients had peri-implantitis and 14.5% had its moderate-to-severe form (Derks et al., 2016).3 Peri-implantitis does not always mean the implant is lost, but it does mean the implant is no longer fully healthy and needs treatment. The 2023 EFP S3 clinical guideline sets out how peri-implant diseases are prevented and managed.2
The crown usually wears out before the implant
The part most people picture — the visible tooth — is not the implant itself. An implant restoration has three parts: the buried titanium fixture, a connector (abutment), and the crown, bridge, or denture attachment on top. The fixture is the part that can last for decades. The crown or prosthesis on top is a wearing part, much like any restoration in the mouth, and it is the component most likely to need repair or replacement first — from normal wear, a chip, a loosened screw, or simply age.
So a realistic expectation is: the implant fixture may serve you for the rest of your life, while the crown attached to it may need replacing once or more over that period. Replacing a crown is a far smaller undertaking than replacing the implant.
What makes an implant last longer — or fail sooner
Longevity is not luck. The main factors are well established:
- Maintenance. Implants need cleaning and professional review for life. A structured recall programme is the single biggest controllable factor in long-term outcomes.
- Smoking. Smokers are substantially more likely to develop peri-implantitis and implant failure.
- Diabetes and general health. Poorly controlled diabetes impairs healing and raises the risk of complications.
- Oral hygiene. Daily cleaning around the implant — usually an interdental brush at minimum — keeps the surrounding tissue healthy.
- History of gum disease. Patients who lost teeth to periodontitis carry that susceptibility forward to the tissue around implants.
- Surgical planning and skill. Correct positioning, an established implant system, and CBCT planning for non-routine cases all support durability.
Common questions
Do dental implants last a lifetime? The implant fixture can last for decades and often for life, but no clinician can guarantee a lifetime for any individual. Pooled survival is about 94.6% at 10 years (Moraschini et al., 2015).1 Outcomes depend on maintenance, smoking, diabetes, and gum health — which is why long-term review matters.
What is the main reason implants fail later on? The dominant cause of late failure is peri-implantitis — inflammatory bone loss around the implant, the implant equivalent of gum disease. It is closely linked to smoking, poor oral hygiene, a history of periodontitis, and the absence of structured maintenance.
Will the crown last as long as the implant? Usually not. The titanium fixture is built to last for decades, but the visible crown is a wearing part and is the component most likely to need repair or replacement first — often well before the implant itself.
Does maintenance in South Africa cost extra? Often, yes. Implant maintenance and recall visits are not automatically contracted in with medical aid, so a co-payment is common. We are happy to give you the relevant procedure codes so you can confirm your own cover before booking.
What this means for you
A dental implant is one of the most durable tooth replacements available, and most implants are still in place a decade after placement (Moraschini et al., 2015).1 But "long-lasting" depends on factors that are partly within your control — maintenance, smoking, oral hygiene, and managing conditions like diabetes — and on the crown on top, which may be replaced sooner than the implant beneath it.

How long an implant is likely to last in your specific case depends on your medical history, smoking status, gum health, bone quality, and your commitment to maintenance — all assessed at a consultation, which gives you a clinical answer for your own situation.
