Dental Implants After Gum Disease: Timeline, Success Rates, Costs

If gum disease took your teeth, the question is rarely whether you can have implants. It is how long the whole process takes, how well implants hold up in a mouth that has already lost bone to infection, and what the bill looks like once you add the periodontal work on top. This guide answers those three questions in order, with the UK timeline, the success figures the studies actually report, and the 2026 costs broken down so you can budget before you ever sit in a chair.

Dental implants after gum disease are a longer and more layered project than implants in a healthy mouth, but the outcomes are good when the work is done in the right sequence. The reason is simple. Treat the periodontitis first, prove the gums hold steady, then place the implants and commit to maintenance for life.

TL;DR

You can have dental implants after gum disease in the UK, but the active infection has to be treated and stable before a single fixture goes in. The full timeline from first consultation to a finished tooth usually runs 6 to 14 months, longer if you need bone grafting. Success rates stay high, with studies reporting implant survival of roughly 90 to 95 per cent at 5 to 10 years for treated periodontitis patients, a few points below the 95 to 98 per cent reported for patients with no gum disease history. Costs are higher than a straightforward case because you pay for periodontal treatment, sometimes grafting, and tighter maintenance on top of the implant itself. Budget £2,500 to £4,500 for a single implant tooth in 2026, plus £200 to £1,500 for the gum treatment that has to come first.

Why gum disease changes the implant equation

Periodontitis is a bone disease driven by a gum infection. Plaque bacteria gather at the gum line, the immune response turns chronic, and the long-running inflammation slowly dissolves the bone that holds teeth in the jaw. By the time teeth are lost or extracted, bone has usually gone with them.

That history matters for implants in two ways. The first is mechanical. An implant fuses to the jawbone in a process called osseointegration, and it needs a healthy, stable envelope of bone around it. If gum disease has thinned or hollowed your ridge, you may need grafting to rebuild a foundation before a fixture can be placed. Our bone graft explainer covers when that step is genuinely needed, and the bone augmentation guide walks through the four rebuilding techniques UK clinics use.

The second is bacterial, and it is the more important of the two. The micro-organisms that undermined your natural teeth do not disappear when those teeth come out. They can colonise the surface of an implant just as readily, producing peri-implantitis, the implant version of gum disease. The fuller clinical picture of candidacy and peri-implantitis risk sits in our companion guide on periodontal disease and dental implants. This article focuses on the three things patients actually ask about once they accept implants are possible: how long, how well, and how much.

The timeline: from first consultation to finished tooth

There is no single number, because gum disease patients sit on a spectrum. A patient with mild, well-controlled periodontitis and good bone can finish in well under a year. A patient who needs surgery, grafting and a long settling period can be a year and a half in. Here is the realistic UK sequence in 2026.

Stage 1: assessment and periodontal stabilisation (1 to 4 months)

Nothing happens until the gum disease is controlled. The clinic starts with a full periodontal assessment: pocket charting around every remaining tooth, bleeding scores, and usually a cone beam CT scan to map your bone in three dimensions. The scan is not optional in a periodontitis case, and our CBCT scan cost guide explains what it shows and what it costs.

Then comes the treatment itself, usually non-surgical first: a deep professional clean below the gum line, sometimes called root surface debridement, to strip out the bacterial deposits driving the inflammation. You are coached on a daily hygiene routine that actually reaches the problem areas, because home care does half the work. Where pockets stay deep, periodontal surgery may be needed to access and clean the roots properly. This stage takes weeks to a few months depending on severity.

Stage 2: the settling period (2 to 4 months)

After treatment, the clinic re-checks. They want shallow pockets, no bleeding on probing, and no sign of active bone loss. Most UK clinics then build in a settling period of two to four months to confirm the gums hold steady rather than rebound. This wait frustrates patients who want to move fast, but it is the single biggest protector of the implants you are about to pay for. Skipping it is the most common reason a periodontitis case fails years later.

Stage 3: grafting, if needed (3 to 9 months added)

If the scan shows you do not have enough bone, grafting comes next. A minor graft placed at the same time as the implant adds little to the timeline. A larger ridge or sinus graft done as a separate stage needs its own healing window of three to nine months before the implant can go in. Whether you need this is the single biggest variable in your total timeline, which is why the CBCT scan in stage 1 matters so much.

Stage 4: implant placement and integration (3 to 6 months)

The fixture is placed, usually under local anaesthetic. It then needs to integrate with the bone, a process that runs three to six months in most cases, longer in a periodontitis patient where the clinic may choose to wait at the cautious end of that range. A temporary tooth bridges the gap in visible areas.

Stage 5: the final crown (a few weeks)

Once integration is confirmed, the abutment and final crown are fitted over two or three short appointments. Then you move straight into the lifelong maintenance phase, which for a gum disease patient is not a footnote but a core part of the treatment.

Add it up and a typical no-graft case runs 6 to 9 months. A case needing a separate graft stage runs 12 to 14 months or more. For context on how this compares with a healthy mouth, our 2026 dental implants cost UK breakdown sets out the standard timeline.

Success rates: what the studies actually report

This is the question that keeps gum disease patients awake, and the honest answer is reassuring with a caveat. Peer-reviewed studies indexed on PubMed consistently show that implants in treated periodontitis patients survive well, just not quite as well as in patients who never had gum disease.

The figures vary by study design and follow-up length, but the pattern is steady:

Patients with no periodontal history: implant survival around 95 to 98 per cent at 5 to 10 years.
Patients with treated, stable periodontitis: implant survival around 90 to 95 per cent at 5 to 10 years.
Patients with untreated or poorly controlled periodontitis: survival falls sharply, and reputable clinics will not place implants in this group at all.

The gap between the first two groups is real but modest. The gap between the second and third is enormous, and it is entirely within your control. Get the gum disease treated and keep it stable, and you sit in the 90 to 95 per cent band. Skip the treatment or let the disease return, and you fall off a cliff.

The reason for the residual gap is peri-implantitis. A treated periodontitis patient remains more susceptible to bacterial breakdown around the implant than someone who never had the disease, because the underlying tendency does not vanish. An implant also 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, and once bone loss starts it is harder to halt than around a tooth. That is why maintenance does so much of the work, and why our implant infection risk breakdown is worth reading alongside this.

It is also why long-term figures matter more than first-year ones for this group. Early failures are rare in any patient. The periodontitis-related difference shows up over years, which is the lens our review of how long dental implants last in the UK applies. If a failure does happen, the reasons and next steps are covered in our guide to dental implant failure rates and what to do next.

The maintenance commitment is part of the success rate

You cannot separate the success figures above from the maintenance behind them. The 90 to 95 per cent survival in treated periodontitis patients is what good clinics see in patients who keep their implants clean and attend supportive care. The numbers are worse in patients who drift away from hygiene appointments.

A gum disease patient with implants signs up for more frequent professional cleaning than the average patient, typically every three to four months rather than twice a year. They also need a home routine that genuinely reaches under and around the implant, which our implant cleaning routine guide sets out step by step. The British Society of Periodontology and Implant Dentistry (BSP) is explicit that supportive periodontal care must continue indefinitely for these patients, and the General Dental Council expects clinicians to plan and document that ongoing care as part of responsible treatment.

This is a genuine cost and time commitment, not an afterthought, so it belongs in your budget from day one. Our piece on annual implant maintenance and check-up costs puts realistic numbers on it.

Costs: the full 2026 breakdown for a gum disease patient

A periodontitis patient pays for three things a healthy patient may not: the gum treatment itself, sometimes grafting, and more intensive ongoing maintenance. Here is how the 2026 UK private numbers stack up.

The periodontal treatment that has to come first

Periodontal assessment and CBCT scan: £100 to £350, sometimes bundled into a consultation.
Non-surgical periodontal therapy (deep cleaning, root surface debridement): £200 to £800 depending on how many quadrants are treated and how many visits are needed.
Periodontal surgery, if pockets stay deep: £500 to £1,500 or more, depending on the number of sites.

So before you have spent a penny on implants, budget £200 to £1,500 for the gum work, with the higher end reflecting surgery.

The implant itself

Single implant with abutment and crown: £2,200 to £3,500 in most of the UK, rising in central London.
Bone graft, if needed: £400 to £1,200 for a minor graft, £1,500 to £3,000 for a major ridge or sinus graft.
Full arch fixed solutions: considerably more, often £12,000 to £25,000 per arch, and a common route for patients who lost most teeth to advanced periodontitis. Our all-on-4 cost breakdown covers this in full.

Ongoing maintenance

Supportive periodontal care, every 3 to 4 months: £80 to £150 per visit, so £240 to £600 a year on top of the implant.

Put together, a single-tooth gum disease case that needs only basic periodontal work and no graft lands around £2,500 to £4,500 all in for the first year. A case needing surgery and grafting can comfortably pass £6,000 for one tooth. These are higher numbers than a healthy mouth, and the extra cost buys the stable foundation the implant needs to survive.

For a full comparison against standard pricing, the 2026 dental implants cost UK breakdown is the reference piece.

Will the NHS pay for any of this?

For most gum disease patients, no. NHS England funds dental implants only for severe medical need, such as head and neck cancer reconstruction, cleft palate or major trauma. Losing teeth to periodontitis, however advanced, does not qualify on its own, as set out in the NHS dental costs guidance. Our guide on who actually qualifies for NHS implants explains the narrow eligibility in detail.

The NHS will, however, treat the gum disease itself. Periodontal therapy is available on the NHS, and the NHS gum disease information covers what that involves. Many patients have the periodontitis stabilised on the NHS and then go private for the implants, which is a sensible way to control cost. The British Dental Association supports a prevention-first approach, and getting the gum disease treated under the NHS first is fully consistent with that.

How to keep your costs and risks down

A few practical moves make a real difference to a gum disease patient.

Treat the periodontitis before you shop for implants. Stabilising the gums first, ideally on the NHS, separates the cheaper unavoidable work from the optional implant spend.
Insist on a CBCT scan early. It tells you whether grafting is on the table, which is the single biggest swing in your final timeline and bill.
Get at least two written quotes from GDC-registered clinics. Make sure each quote spells out the periodontal work, any grafting, the implant, and the maintenance schedule, not just the headline implant price.
Be wary of any clinic offering same-day implants without treating your gums first. That is a red flag in a periodontitis case. Our checklist on how to spot a dodgy implant quote in 30 seconds covers the warning signs.
Budget for maintenance, not just placement. The three-to-four-monthly supportive care is what keeps you in the 90 to 95 per cent survival band.
Commit to the home routine. It is free, and it does as much for your implant as anything the clinic does.

Our free service at /#quote-form connects gum disease patients with vetted UK clinics that handle periodontitis cases properly, so you can compare written plans rather than guess.

Frequently asked questions

Can you get dental implants if you have had gum disease?

Yes, in most cases, provided the gum disease is treated and stable first. Active, untreated periodontitis is a clear reason for a UK clinic to delay implant surgery, because the same bacteria that destroyed bone around your teeth can attack the bone around an implant. Once the periodontitis is stabilised, the gums hold steady, and any needed grafting is done, implants are placed and supported by lifelong maintenance. Studies on PubMed report survival of roughly 90 to 95 per cent at 5 to 10 years for this group, a few points below patients with no gum disease history but still high.

How long after gum disease treatment can I have implants?

Most UK clinics wait two to four months after stabilising the periodontitis before placing implants, to confirm the improvement holds rather than rebounds. If grafting is needed, that adds a separate healing window of three to nine months before the implant goes in. The full path from first consultation to a finished tooth usually runs 6 to 9 months without grafting, or 12 to 14 months or more with it. The wait is not red tape; it is the single biggest protector of the implants you are paying for.

Are implants more likely to fail if I had periodontitis?

Slightly more likely, but still very likely to succeed. Treated periodontitis patients show implant survival around 90 to 95 per cent at 5 to 10 years, against 95 to 98 per cent for patients with no gum disease history. The residual gap is driven by peri-implantitis, because a periodontitis-susceptible patient remains more prone to bacterial breakdown around the implant. The risk is managed, not eliminated, by treating the gums first and committing to frequent supportive care. Patients who skip maintenance see worse outcomes, which is why the British Society of Periodontology and Implant Dentistry (BSP) insists on indefinite supportive care for this group.

How much do implants cost if I have gum disease?

More than a straightforward case, because you pay for the periodontal treatment, sometimes grafting, and tighter maintenance on top of the implant. Budget £200 to £1,500 for the gum work first, then £2,200 to £3,500 for a single implant with crown, plus £400 to £3,000 if grafting is needed. Add £240 to £600 a year for supportive care. A simple single-tooth case lands around £2,500 to £4,500 in the first year; a complex one with surgery and grafting can pass £6,000 for one tooth. Get at least two written quotes that itemise every stage.

Will the NHS cover implants after gum disease?

Almost never for the implants themselves. NHS England funds implants only for severe medical need such as cancer reconstruction, cleft palate or major trauma, and tooth loss from periodontitis does not qualify on its own, as the NHS dental costs guidance makes clear. The NHS will, however, treat the gum disease itself. A sensible route is to have the periodontitis stabilised on the NHS, then go private for the implants, which separates the unavoidable treatment from the optional spend.

What happens if my gum disease comes back after implants?

If periodontitis returns and is not caught early, it can spread to the tissue around your implants as peri-implantitis, leading to bone loss and eventual implant failure. This is exactly why supportive periodontal care every three to four months is built into the treatment plan, not offered as an extra. Caught early, peri-implantitis can often be managed with intensive cleaning and, in some cases, surgical treatment. Left late, it is hard to reverse. The warning signs and wider context are covered in our implant infection risk breakdown, and the prevention routine in our implant cleaning guide.
