Maladie parodontale et implants : oui, mais comment ?

Most people who lose teeth to gum disease assume implants are off the table. The logic feels sound: if your gums could not hold natural teeth, why would they hold artificial ones? It is a fair question, and the honest answer is more reassuring than you might expect, but it comes with conditions that UK clinics take seriously. Periodontal disease does not rule out implants. It changes the order of treatment, the risk profile and the level of maintenance you sign up for, and a good clinic will not place a single fixture until your gums are under control.

TL;DR

You can usually have dental implants after periodontal disease in the UK, but only once the gum disease is treated and stable first. Active, untreated periodontitis is one of the clearest reasons a clinic should delay implant surgery, because the same bacteria that destroyed bone around your natural teeth can attack the bone around an implant, a condition called peri-implantitis. Patients with a history of treated gum disease have a higher long-term risk of peri-implantitis than those who never had it, with peer-reviewed studies putting that risk meaningfully above the baseline. The route to a good outcome is straightforward in principle: get the periodontitis treated and stabilised, prove the gums hold steady, then place implants and commit to a strict hygiene and maintenance routine for life. Done in that order, success rates remain high. Skip the order, and the failure rate climbs sharply.

What periodontal disease actually does to bone

Periodontal disease, or periodontitis, is not a gum problem in the way most people picture it. It is a bone problem driven by a gum infection. Plaque bacteria collect at the gum line, the body's immune response to that bacteria turns chronic, and the collateral damage of that long-running inflammation is the slow destruction of the bone and fibres that anchor teeth in the jaw. Gums recede, pockets deepen, teeth loosen, and eventually they are lost or extracted.

That distinction matters enormously for implants, because an implant relies on exactly the tissue periodontitis destroys: bone. An implant is a titanium fixture that fuses with the jawbone in a process called osseointegration, and it needs a healthy, stable envelope of bone around it to stay put. If you have lost teeth to periodontitis, you have almost certainly lost bone with them, which is why a proportion of these patients need grafting before implants are even feasible. Our bone graft explainer covers when that step is needed and our bone augmentation guide walks through the four techniques UK clinics use to rebuild it.

The deeper concern is not the bone you have already lost. It is the bacteria that caused the loss in the first place. Periodontal disease is, at root, a bacterial imbalance in the mouth, and placing an implant does not reset that ecosystem. The same micro-organisms that undermined your teeth are still present, and they can colonise the surface of an implant just as readily.

Peri-implantitis: the same disease in a new place

Peri-implantitis is the implant version of periodontitis. The biology rhymes almost exactly. Bacteria gather where the implant meets the gum, the immune response turns chronic, and the bone supporting the implant begins to dissolve. Left unchecked, the implant loosens and is lost, often years after it was placed and apparently doing fine.

This is the central reason a history of gum disease matters. Multiple peer-reviewed studies indexed on PubMed consistently report that patients with treated periodontitis develop peri-implantitis more often than patients with no periodontal history. The exact figures vary by study design and follow-up length, but the direction is unambiguous and the gap is large enough to change how clinics plan treatment. A periodontitis-susceptible patient is not a poor candidate, but they are a higher-maintenance one, and pretending otherwise sets up the implant to fail.

What makes peri-implantitis particularly stubborn is that an implant has no periodontal ligament, the cushioning fibre layer that surrounds a natural tooth and brings its own blood supply and immune defences. The seal between gum and implant is more vulnerable to bacterial breakdown, and once bone loss starts around an implant it is harder to halt and harder to repair than around a tooth. Prevention is doing almost all the work here, which is exactly why the pre-treatment and maintenance steps are non-negotiable. We cover the wider picture in our implant infection risk breakdown.

The non-negotiable first step: treat the gum disease

No reputable UK clinic should place an implant in a mouth with active periodontitis. This is not caution for its own sake. It is the single most important factor in whether the implant survives. The British Society of Periodontology and Implant Dentistry is explicit that periodontal health must be established before implant therapy, and the General Dental Council expects clinicians to assess and stabilise periodontal disease as part of responsible treatment planning.

Treating periodontitis before implants usually runs through a recognised sequence. It starts with a full periodontal assessment, including pocket charting around every remaining tooth and often X-rays or a CBCT scan to map bone levels. Then comes non-surgical therapy: a deep professional clean below the gum line, sometimes called root surface debridement or scaling and root planing, to remove the bacterial deposits driving the inflammation. Alongside that, the clinic coaches you on a daily hygiene routine that actually reaches the problem areas, because home care is half the treatment. Where pockets stay deep despite non-surgical work, periodontal surgery may be needed to access and clean the roots more thoroughly.

After treatment, the clinic re-assesses. The goal is stability: shallow pockets, no bleeding on probing, no active bone loss. Reaching that state is the green light for implants. Many clinics build in a settling period of several months between stabilising the gums and placing fixtures, to confirm the improvement holds rather than rebounds.

How clinics judge whether you are ready

When a UK clinic decides whether to proceed, they are weighing several things at once rather than ticking a single box. The first is whether the periodontal disease is genuinely controlled, not merely cleaned once. They look for stable pocket depths over time and an absence of bleeding, which is the most reliable everyday sign that inflammation has settled.

The second is your engagement with hygiene. This sounds soft, but it is one of the strongest predictors of implant success in a periodontitis patient. A clinic wants to see that you have adopted and sustained an effective cleaning routine, because the long-term defence against peri-implantitis is largely in your hands. A patient who has clearly turned their oral care around is a far safer candidate than one with the same clinical numbers but no behaviour change.

The third is your wider risk profile. Smoking is the heaviest weight on the scale: it both worsens periodontitis and sharply raises peri-implantitis risk, and many clinics will press hard for you to stop, with some declining elective implant work for current smokers. Our piece on what clinics really ask smokers sets out how this conversation tends to go. Poorly controlled diabetes is another major factor, since it impairs healing and amplifies gum infection; our diabetes and implants guide explains how UK clinics handle it. None of these rule you out automatically, but each one raises the bar for proof that the disease is under control.

Success rates when it is done properly

The reassuring headline is that treated periodontitis patients still achieve high implant success when the process is followed. Peer-reviewed long-term data show survival rates for implants in periodontally treated patients that sit only modestly below those of patients with no periodontal history, often still well into the nineties as a percentage over several years, provided two conditions are met: the disease was stabilised before placement, and the patient stays on a structured maintenance programme afterwards.

Those two conditions are doing the heavy lifting. Studies that follow periodontitis patients who skipped regular maintenance, or who were never properly stabilised, report markedly worse outcomes, with more peri-implantitis and more late failures. The implant hardware is rarely the problem. The biology around it is, and the biology is manageable. This is the same theme that runs through our analysis of why implants fail: inadequate gum and bone health, not the fixture itself, is the recurring culprit.

It is worth being honest about the residual risk. A periodontitis history never fully disappears as a risk factor. Even a perfectly maintained patient carries a slightly higher lifetime chance of peri-implantitis than someone who never had gum disease. That is not a reason to avoid implants; it is a reason to go in with clear eyes about the maintenance commitment, which for these patients is a permanent part of the deal rather than an optional extra.

The maintenance commitment that comes with it

For a periodontitis patient, implant maintenance is not aftercare you can taper off once everything feels settled. It is a lifelong programme, and it is the price of the high success rates above. The core of it is a strict daily hygiene routine at home plus regular professional reviews, usually more frequent than the standard six-monthly check.

At home, the routine has to reach the gum margin around each implant, where peri-implantitis starts. That typically means careful twice-daily brushing, daily cleaning between teeth and around implants with interdental brushes or floss suited to the gaps, and often an antimicrobial mouthwash where the clinic advises it. Our implant cleaning routine sets out a practical version of this for everyday use.

Professionally, the clinic will want to see you on a maintenance recall, often every three to four months for higher-risk patients, where a hygienist or dentist cleans around the implants, charts the gum health, checks for early bleeding or pocketing and catches problems while they are still reversible. Early peri-implant inflammation, called peri-implant mucositis, is treatable and often reversible if caught before it reaches bone, which is the whole point of frequent reviews. Miss the reviews, and the first sign of trouble may be a loose implant years too late to save it.

Warning signs to watch for after placement

Because peri-implantitis is so much easier to manage early, knowing what an early problem looks like is part of protecting your investment. The tells are quiet at first, which is exactly why they get missed. The earliest and most reliable sign is bleeding when you clean around the implant, the same warning that flags gum disease around natural teeth. Healthy tissue around a well-maintained implant should not bleed during normal brushing or interdental cleaning, so blood on the brush is a prompt to mention it rather than ignore it.

Other early signals include gum that looks redder or more swollen around one implant than the others, tenderness that does not settle, or a gum line that appears to be creeping back and exposing more of the crown or abutment. A bad taste or a persistent slightly unpleasant smell from one area can point to infection brewing below the surface. None of these means the implant is lost. Caught at the mucositis stage, before bone is involved, the inflammation is usually reversible with a professional clean and a tightening of your home routine. The danger sign that demands a same-week call is any sense that the implant or crown is moving, because true mobility of an integrated implant indicates bone loss has already advanced and the window for easy treatment has likely closed.

For a periodontitis patient, the safest posture is to assume nothing is too minor to mention at a review. The clinic would far rather see you about a spot of bleeding that turns out to be nothing than discover advanced peri-implantitis at a routine check a year later.

Questions worth asking before you commit

A clinic's answers to a few direct questions tell you a great deal about whether they treat periodontitis patients properly. Ask how they will assess and stabilise your gum disease before any implant, and listen for a clear sequence rather than a vague reassurance. A clinic that talks you straight to surgery without a periodontal plan is a clinic to be wary of.

Ask what your specific peri-implantitis risk looks like given your history, and what maintenance schedule they would put you on afterwards. A thoughtful answer will acknowledge the raised risk honestly and lay out a recall plan, usually three to four monthly, rather than waving the concern away. Ask whether grafting is likely in your case and, if so, for it to be itemised separately on the quote. Finally, ask who is actually carrying out the work and check their registration and any specialist listing on the General Dental Council register, since complex periodontitis cases often benefit from a clinician with periodontal or implant specialist training.

The pattern across all of these is the same. The right clinic for a periodontitis patient is the one that takes the gum history seriously, builds the treatment around it, and is candid about the lifelong maintenance involved, rather than the one offering the fastest or cheapest route to a fitted tooth.

A practical path forward

If you have lost teeth to gum disease and want implants, the path is clearer than the worry suggests. Find a clinic that treats periodontal stabilisation as a prerequisite rather than an inconvenience, because the ones that rush you to surgery are the ones whose implants tend to fail. Expect a full periodontal assessment first, then treatment, then a proving period, and only then implants. Expect grafting to be on the table if bone loss has been significant, and ask for it as a clearly itemised line on your quote rather than a vague bundled figure, the same advice we give in our cost breakdown.

Above all, treat the maintenance programme as part of the treatment, not an add-on. The patients who do best are not the ones with the most expensive implants. They are the ones who stabilised their gums first and then never let them slide again. With that order respected, a history of periodontal disease becomes a managed risk rather than a barrier, and a well-placed implant can outlast the teeth the disease took.

FAQ

Can I get dental implants if I have gum disease?

Not while the gum disease is active. UK clinics treat and stabilise periodontitis first, then re-assess your gum health before placing any implant. Once the disease is controlled, pockets are shallow and there is no bleeding on probing, implants are usually possible. Placing an implant into an actively infected mouth is one of the clearest avoidable causes of early failure, which is why the order of treatment matters so much.

Does a history of periodontal disease make implants more likely to fail?

It raises the long-term risk rather than guaranteeing failure. Peer-reviewed studies show treated periodontitis patients develop peri-implantitis more often than patients with no gum disease history, but survival rates stay high when the disease was stabilised before placement and the patient sticks to a structured maintenance programme. The hardware rarely fails. The gum and bone health around it is what determines the outcome.

What is peri-implantitis and how is it different from gum disease?

Peri-implantitis is essentially gum disease around an implant rather than a natural tooth. The same bacteria trigger chronic inflammation that destroys the supporting bone, eventually loosening the implant. The key difference is that an implant lacks the periodontal ligament that surrounds a natural tooth, so its seal against bacteria is more fragile and bone loss, once started, is harder to halt or repair.

How often will I need check-ups after implants if I had periodontitis?

More often than the standard six-monthly review. Many UK clinics place higher-risk patients on a three to four monthly maintenance recall, where a hygienist cleans around the implants, charts gum health and catches early inflammation before it reaches bone. These frequent reviews are the main reason periodontitis patients still achieve good long-term results, so they are a permanent part of the plan rather than optional.

Will I need a bone graft because of the bone I lost to gum disease?

Possibly. Periodontitis destroys bone as it progresses, so patients who lost teeth to it have often lost supporting bone too, and some need grafting before implants are feasible. Whether you do depends on how much bone remains, which a CBCT scan shows precisely. If grafting is needed, ask for it as a separate line on your quote, since it is a common place for a low headline price to climb later.
