How Long Do Dental Implants Last?

How long do dental implants last on average

Most modern dental implants are still in place after 10 years, and the published figures agree with each other. A meta-analysis of 18 prospective studies on contemporary rough-surface screw implants found 10-year survival at implant level of 96.4% (PubMed 30904559). When the authors also accounted for patients lost to follow-up, the estimate fell to 93.2%, which they consider closer to real-world practice (PubMed 30904559).

Survival and success are different measures. Survival only tells you the implant is still in the mouth; success means it is working without bone loss, inflammation or pain. A systematic review of 23 studies with at least 10 years of follow-up, covering 7,711 implants, reported a mean follow-up of 13.4 years, mean survival of 94.6% and mean marginal bone loss of 1.3 mm (PubMed 25467739). Only 14 of those studies reported success rates, each with its own criteria (PubMed 25467739). So "what percentage of implants succeed" has no single answer, while "what percentage are still there" has a consistent one. The stages of treatment are set out on our dental implant treatment page.

Can a dental implant last a lifetime

No one can promise that an implant will last a lifetime, but most implants followed for more than 20 years are still in place, and losses build up slowly over the years. A meta-analysis of prospective studies with at least 20 years of follow-up pooled 10 studies and 1,857 implants; 1,028 were followed for 20 years or longer, 115 failed, and 20-year survival was 93.0% (PubMed 42173763). Where the cause of failure was recorded, in 44 implants, it split almost evenly between biological and mechanical causes (PubMed 42173763).

An earlier 20-year meta-analysis drew a more cautious picture. It found 92% survival in 3 prospective studies and 88% in 5 retrospective studies, and the prospective estimate fell to 78% once missing data were imputed (PubMed 39305362). Its authors concluded that follow-up should not end after placement, or even after 10 years (PubMed 39305362).

On this evidence, 20 years is a realistic horizon for an implant. Whether it lasts for life depends on home care, regular check-ups, smoking and general health. The "lifetime warranty" printed on many treatment quotes is not a clinical forecast; it is usually a manufacturer's commitment to replace components under stated conditions. Our article on implant warranties across borders explains how those documents differ.

Does the crown last as long as the implant

The implant and the crown fitted on it are separate parts with separate lifespans. The crown is replaced more often. A meta-analysis of 46 studies on single-tooth implants with a mean follow-up of at least 5 years found implant survival of 97.2% at 5 years and 95.2% at 10 years; for the crowns on those implants the figures were 96.3% at 5 years and 89.4% at 10 years (PubMed 23062124).

Technical problems were common in the same review: within 5 years, screw loosening occurred in 8.8%, loss of retention in 4.1% and fracture of the veneering ceramic in 3.5% (PubMed 23062124). Most of these do not cost you the implant itself; a loose screw is retightened, a crown that has come off is recemented, or the crown is remade. When patients ask how long an implant lasts, they often mean the tooth they can see. Keeping the implant healthy in the bone and renewing the visible crown are two different jobs, and knowing that from the start sets the right expectations.

Replacing a crown does not mean removing the implant. Because the abutment and screw connect into the implant, the implant normally stays in the bone when the crown is changed, and the timing is judged at a routine check-up.

Why do dental implants fail years later

The main long-term threat to an implant is peri-implantitis, an inflammation of the gum and bone around it. A meta-analysis of 20 studies using the 2017 World Workshop criteria found peri-implantitis in 25.0% of patients and 18.0% of implants (PubMed 40523497). An earlier epidemiology review showed that its prevalence rises the longer an implant has been in function (PubMed 25495683). Early signs and treatment options are covered in our peri-implantitis guide.

A history of gum disease raises the risk. A meta-analysis pooling 22 studies found that implants placed in patients treated for periodontitis failed in 5.37% of cases, against 3.84% in periodontally healthy patients, a risk ratio of 1.78 (PubMed 25283479). None of those studies was randomised, so the authors ask for the result to be read with caution (PubMed 25283479).

Smoking is the risk factor patients can change themselves. A meta-analysis of 292 publications found that implants in smokers had a 140.2% higher risk of failure than implants in non-smokers (PubMed 35056347). The lack of firm, attached gum around the implant, known as keratinised mucosa, also matters: across 16 cross-sectional studies it was associated with more peri-implantitis, with an odds ratio of 2.78 (PubMed 36882495).

How to make a dental implant last longer

The approach with evidence behind it combines daily plaque removal at home with regular professional maintenance. A consensus report on preventing peri-implantitis named plaque as the cause of peri-implant inflammation and mechanical brushing as an effective preventive measure, and found that patients with mucositis who missed regular supportive care were at higher risk of developing peri-implantitis (PubMed 25626479). The same report treats bleeding on probing as the key clinical sign separating a healthy implant from a diseased one (PubMed 25626479).

On recall intervals, a meta-analysis of 13 clinical trials suggested a maintenance visit at least every 5 to 6 months, tailored to each patient's risk, and noted that biological complications can still occur under maintenance (PubMed 26701350). The home routine with interdental brushes, floss and water flossers is set out in our implant cleaning guide.

If your implants are placed abroad, decide before you fly home which dentist will see you for those visits. Bleeding, swelling or a bad taste around the implant, a loose crown or any movement of the implant is a reason to book an examination without waiting for the next recall. Mucositis, the early stage of this process, can be managed before it reaches the bone.

Do age, diabetes or implant brand affect how long implants last

Older age and well-controlled general conditions do not by themselves make implants short-lived, but some situations clearly raise the risk. A systematic review of 60 studies on older patients and medical conditions found pooled implant survival of 97.3% at 1 year and 96.1% at 5 years, and survival was also reported to be high in people with type II diabetes or Parkinson's disease (PubMed 30328186). In the same review, radiotherapy reduced implant survival in cancer patients, and people on high-dose antiresorptive drugs for bone metastases carried a high risk of complications after implant surgery (PubMed 30328186).

Age also shows in long-term data. A meta-analysis of 18 prospective studies following rough-surface implants for 10 years found survival of 91.5% in patients aged 65 and over once patients lost to follow-up were accounted for (PubMed 30904559). That is still high, but it is a reason to keep check-ups closer together in this age group.

Brand is part of the picture too. Survival data are published system by system, and the right system is chosen for the bone volume, the site and the planned restoration. There is no reliable comparison that gives one lifespan figure for Swiss, Swedish or Korean implants as a group. How systems are chosen is explained in why implant brand matters.
