How long do dental implants last?
Published long-term data puts implant survival at around 95% at ten years in suitable, well-maintained cases. The part most people miss is that an implant is not one object. The titanium post placed in the jaw is designed to last decades. The crown fitted on top of it is a restoration, and it will eventually need replacing, commonly after 10 to 15 years depending on bite forces, grinding and wear.
That distinction explains why answers to this question vary so much. A page telling you implants last fifteen years and one telling you they last thirty may both be describing something real, just different parts of the same tooth.
What the long-term studies actually show
Implants have been followed over long periods, which is unusual in dentistry and genuinely useful here. The figure of around 95% survival at ten years comes from that body of published data, and it carries two honest caveats.
The first is the phrase "suitable, well-maintained cases". Survival figures describe people who were good candidates to begin with and who kept up their maintenance, which is exactly the group most likely to do well. The second is that survival means the implant is still in place and doing its job, which is not quite the same as it never having caused any trouble along the way.
Neither caveat undermines the picture. They explain why no dentist can promise you a figure for your own mouth. What no study supports is the idea that any dental treatment is permanent. Implants are a long-term replacement for a missing tooth, not a fit-and-forget one.
The post and the crown do not last the same length of time
The titanium post fuses with the bone over three to six months and, once integrated, is designed to stay put. It does not decay and it does not wear the way a tooth does.
The crown is a different story. It does the chewing, and like any restoration it can chip, wear at the biting surface, or need replacing on appearance grounds as the gum line around it changes over the years. Commonly that is after 10 to 15 years, and at Stella Dental a replacement crown is currently £850. Needing one is not implant failure. It is maintenance, in the same way a well-built house eventually needs a new roof without the foundations being at fault.
What affects how long an implant lasts?
Longevity depends far more on gum health, your hygiene maintenance programme and smoking status than on the implant itself.
Gum health and plaque control
This is the single biggest factor within your control. The bone and gum around an implant are living tissue, and plaque left at the margin causes inflammation there just as it does around a natural tooth. Cleaning around the implant with interdental brushes daily, not only brushing across it, is what protects that margin.
Smoking
Smoking reduces blood flow to the gums and is consistently associated with higher implant failure rates and slower healing. It affects both whether an implant integrates in the first place and how it fares over the years afterwards. Cutting down before treatment and staying off it afterwards makes a real difference.
Diabetes and general health
Poorly controlled diabetes affects healing in much the same way smoking does. Well-controlled diabetes is generally not a barrier to implant treatment. We would rather discuss this openly than decline you outright, and it is worth raising at your assessment rather than leaving it unsaid.
Grinding and clenching
Grinding loads an implant in ways it was not designed for, and bite forces are one of the things that determine how long the crown lasts. If you grind, say so. A night guard materially extends the life of the work, and it is a small thing to protect a considerable investment.
How much bone supported it to begin with
Suitability depends on sufficient healthy bone and stable gum health. Where a tooth has been missing for some time, the bone that supported it shrinks, sometimes leaving too little height or width to hold an implant securely. Grafting rebuilds that volume, either at the same appointment as placement or as a separate procedure months beforehand, and an implant placed into good bone starts from a stronger position than one placed into a compromised site.
Peri-implantitis: the main reason implants fail years later
Implants do not decay, but the gum and bone around them can become inflamed, and that is the single most common reason implants are lost. It progresses quietly, with bone lost gradually around the implant until its support is compromised. Bone that has been lost does not grow back on its own, which is why catching it early matters so much.
Early signs are bleeding when you clean around the implant, tenderness, or gum that looks puffy at the margin. None of these is dramatic, which is precisely the problem, and it is why an implant needs reviewing whether or not it is bothering you.
Early failure is a different thing. It happens in the first months, when an implant does not integrate with the bone as it should. Along with infection at placement, these are the main risks, and the ones specific to your case are set out in your written treatment plan and gone through with you before you consent.
How do I make my implant last?
The honest answer is unglamorous: much the same care as a natural tooth, done consistently.
- Brush twice daily, angling at the gum margin around the implant rather than skating over it.
- Clean around the implant every day with interdental brushes, which generally reach around an implant crown better than floss does. Your hygienist can size them for you.
- Keep to your dental hygiene appointments. Intervals are set individually on risk rather than a fixed schedule, and people with implants are seen more frequently.
- Avoid smoking, and get diabetes well controlled if it applies to you.
- Mention grinding, tenderness or bleeding early. These are the things worth troubling us about.
What does it cost to keep an implant healthy?
At Stella Dental a routine examination is £75, and hygiene appointments run from £70 to £165 depending on how much time your case needs. A replacement crown, if you eventually need one, is currently £850. Those reviews are what stop a small problem around an implant becoming a lost implant, so they are better thought of as part of the treatment than as an optional extra. The full fee list is on our published price list.
Is an implant a good long-term investment?
It depends on what you are comparing it with, so here are the numbers. A single dental implant at Stella Dental starts from £2,550. A bridge starts from £850 and dentures from £250, so an implant is plainly the larger outlay at the outset.
What you are buying for the difference is a replacement that stands on its own. An implant is the only tooth replacement that restores the root as well as the visible tooth. It does not rely on the teeth either side, which a bridge does, and it does not sit on the gum, which a denture does. Bridges commonly last ten to fifteen years, and dentures need relining every few years as the jaw changes shape, with full replacement usually needed every five to ten years. Over a long enough period, a restoration that leaves the neighbouring teeth alone and does not need remaking as the ridge changes can compare more favourably than the first figure suggests.
That is a genuine trade-off, not a foregone conclusion, and it depends on your mouth, your age and what else is going on in it. You can read more on the truth about dental implants, or, if you are at the beginning of this, everything you need to know about tooth implants. If you are missing more than one tooth, replacing several teeth at once may be more relevant, and there is a local cost breakdown for what dental implants cost in Stafford.

Frequently asked questions
Are dental implants permanent?
No dental treatment can honestly be called permanent. The implant post is designed to last decades, and published data puts survival at around 95% at ten years in suitable, well-maintained cases, but it still needs looking after and reviewing.
How often will the crown need replacing?
Commonly after 10 to 15 years, depending on bite forces, grinding and wear. The crown is a restoration rather than part of the implant, and replacing one is currently £850.
Do dental implants ever fail?
Yes, though it is uncommon. The main risks are infection at placement, failure to integrate with the bone in the first months, and peri-implantitis later on, where the gum and bone around the implant become inflamed.
Does smoking affect how long an implant lasts?
It does. Smoking reduces blood flow to the gums and is consistently associated with higher failure rates and slower healing. Stopping, or at least cutting down around treatment, is one of the more useful things you can do.
Can peri-implantitis be treated?
It can be controlled, particularly when picked up early, which is the whole argument for regular reviews. Bone already lost does not grow back on its own, so the goal is stopping it progressing.
Do I still need to see a hygienist if my implant is not a natural tooth?
Yes, and more often than most. The implant cannot decay, but the gum and bone holding it are natural tissue and need the same attention. Hygiene intervals are set on risk, and people with implants are seen more frequently.
Is an implant cheaper than a bridge over time?
Not at the outset. A bridge starts from £850 against £2,550 for an implant, and both commonly last well over a decade. The comparison turns on what each does to the teeth around it, which is a conversation for your assessment.
