Alternatives to dental implants: bridges, dentures and what each one involves
If an implant has been ruled out, the realistic options are a conventional bridge anchored to the teeth on either side of the gap, an adhesive bridge that leaves those teeth almost untouched, and a removable denture, partial or complete. Each of these replaces the visible crown of the missing tooth. None of them replaces its root, and that single difference drives how long they last, how they are maintained and how much of the cost the NHS absorbs. For a lower denture that will not stay in place, a fourth route exists: an implant-retained overdenture, which needs far fewer implants than a full fixed restoration.
Which one suits you depends on how many teeth are missing and where they sit, on the condition of the teeth still in place, on what your mouth will tolerate day to day and on what you are able to spend. This article works through the options against those criteria, then sets out what the NHS charges for them and how private fees are built up. The implant treatment itself is described on our dental implant page.
What an implant does that the alternatives cannot
A dental implant is an artificial root, usually titanium, placed into the jawbone. Once osseointegration has taken place over the following months, it carries a crown, a bridge or a full-arch prosthesis. The bridges and dentures discussed below work on a different principle: support comes from the remaining teeth, from the gum and from the palate, and the bone is never entered.
That distinction has measurable consequences. After an extraction the ridge remodels, and the systematic review by Tan et al. (2012) put the average horizontal reduction at 3.79 mm and the vertical reduction at roughly 1.24 mm on the buccal side six months after the tooth came out, the horizontal loss amounting to between 29% and 63% of the ridge width across the studies reviewed. Those figures describe an extraction socket left to heal on its own, without grafting or immediate placement. What they give you is the scale of the change taking place underneath a bridge or a denture, which is why an appliance that fitted perfectly on the day it was seated tends to work loose within a few years.
A missing tooth is rarely only a cosmetic matter. The neighbouring teeth drift towards the space, the opposing tooth over-erupts because nothing meets it, and chewing shifts to the other side of the mouth. Filling the gap, by whichever method, is first of all a way of holding that arrangement steady.
Cost is the other half of the question, and in the UK it is largely settled by what the NHS will and will not provide. Implants are not routinely available on the NHS: the health service describes them as usually private and expensive, with rare exceptions for patients who cannot wear dentures because of mouth cancer or trauma. Those exceptions are examined in our article on dental implants on the NHS. Crowns, bridges and dentures, by contrast, all fall within NHS Band 3. The figures are set out further down this page.
Not enough bone: grafting, sinus lifts and the waiting involved
An implant needs a certain height and thickness of bone to hold. Where the ridge has resorbed, or where the maxillary sinus sits too low, the surgeon will propose rebuilding the site first. Bone grafting restores the missing volume, whilst a sinus lift raises the sinus membrane to create the height needed for placement.
Both are routine procedures with well-documented outcomes, but they stretch the timetable considerably. Several months usually pass between the graft and implant placement, followed by a further healing period before the definitive prosthesis is made. For someone who simply wants to chew properly again within a reasonable time, that delay is on its own a reason to look elsewhere, quite apart from any medical consideration.
Medical reasons an implant may be ruled out
Some medical conditions rule implant surgery out, or postpone it until they have been treated: severe heart failure, valve disease, a recent myocardial infarction, active cancer treatment, radiotherapy to the jaws, and immunosuppression whether inherited or caused by medication. Osteoporosis treatment with bisphosphonates or denosumab also calls for a conversation with the prescribing doctor before any surgery, since those drugs are associated with osteonecrosis of the jaw, a rare but serious complication of bone surgery. No such treatment should ever be stopped on your own initiative.
Other obstacles are temporary and can be worked on beforehand. Poorly controlled diabetes, active gum disease, inadequate oral hygiene and heavy smoking all raise the chance of failure without ruling surgery out permanently. Bruxism tends to influence the design of the restoration and the use of a night guard rather than the decision itself.
One widespread misconception deserves correcting: peri-implantitis is not the body rejecting the implant. It is a bacterial, inflammatory disease of the tissues surrounding the implant, closer in mechanism to periodontitis, with progressive bone loss if it goes untreated; titanium itself is well tolerated by the tissues. The risks of dental implants and their warning signs are covered in a separate article.
The alternatives, option by option
The survival figures quoted below come from clinical studies at five, ten or fifteen years. They give the proportion of restorations still in place at those milestones. Staying in place and staying trouble-free are two separate measures, and neither one predicts what will happen in your own mouth.
The conventional bridge
A conventional bridge replaces one or more missing teeth by resting on the teeth that border the gap. Those abutment teeth are prepared for crowns joined to the pontic between them, and the whole unit is cemented in place, so it works from the day it is fitted.
The meta-analysis by Pjetursson et al. (2007) puts survival of conventional tooth-supported bridges at 93.8% at five years and 89.2% at ten years. Cantilever designs, supported on one side only, drop to 80.3% at ten years. The more useful finding in that review concerns complications rather than survival: for conventional bridges the commonest problems were biological ones, caries on the abutment teeth and loss of pulp vitality, affecting 15.7% of patients over five years. The real cost of a bridge is therefore measured partly in the condition of the two teeth that had to be prepared to carry it.
That trade-off makes sense when the neighbouring teeth are already crowned, or damaged enough to need crowning anyway. It is a harder argument when they are sound.
The adhesive or Maryland bridge
An adhesive bridge, widely known as a Maryland bridge, holds the replacement tooth with a wing bonded to the inner surface of an adjacent tooth. Preparation is limited to a small amount of enamel, sometimes a shallow groove on the cingulum, so the supporting tooth keeps its structure and its nerve.
Kern (2017) followed twenty-two anterior all-ceramic cantilever adhesive bridges over an average of more than fifteen years and reported 95.4% survival at both ten and fifteen years, falling to 81.8% by eighteen years, with no debonding at all in that series. That series is small and single-centre. A systematic review of all-ceramic adhesive bridges (Chen et al., 2018) gives a broader picture: estimated survival of 91.2% at five years, with debonding in 12.2% of cases and fracture in 4.8%, and better results for single-wing designs than for two-wing ones. Debonding is the characteristic failure, usually put right by rebonding the same restoration rather than making a new one.
This is the option to raise when a single front tooth is missing, the bite is favourable and the adjacent teeth are untouched. It is not designed to carry the load of the back of the mouth.
Partial dentures
A partial denture replaces one or more teeth on the same arch, including teeth spread across it. Artificial teeth sit in a base that imitates the gum, and clasps grip the remaining teeth. Acrylic versions are quick to make and cheap, which is why they are so often used as a temporary measure after extractions; they stain, they need bulk to stay strong and they break if dropped. A cobalt-chrome framework is thinner, more stable and kinder to the gum and the supporting teeth.
The follow-up data are worth knowing before committing. Vermeulen et al. (1996) tracked 886 metal-framework partial dentures and found that, taking replacement or the patient giving up wearing it as the failure criterion, 75% were still in service at five years and 50% at ten. Framework fractures affected 10% to 20% of appliances at five years, rising to between 27% and 44% at ten. That study involved simple designs and patients kept under regular recall, which is close to a best case.
In practice those figures amount to a maintenance rhythm: relines, adjustments and, for roughly half of wearers, a replacement after a decade.
Complete dentures
A complete denture replaces a whole arch. In the upper jaw it covers the palate and is held by suction, which usually makes it stable. In the lower jaw the supporting surface is a narrow horseshoe of ridge, and that is where most complaints originate: the denture lifts, the base rubs, food works its way underneath.
Comfort depends heavily on how much bone remains, and that reduces over the years of being edentulous. Biting force stays below what a bridge or an implant-supported restoration delivers, and the first weeks of wear call for patience and a series of adjustments. The NHS advises removing dentures overnight, cleaning them daily and expecting the fit to change as the gums and jawbone alter with age.
Implant-retained overdentures and mini implants
Between a conventional denture and a full fixed restoration sits an intermediate option: keeping a removable denture but anchoring it on two implants placed at the front of the lower jaw. The meta-analysis by Abou-Ayash et al. (2023), covering 28 studies and 1,457 patients, found a large positive effect on patient-reported satisfaction and quality of life for edentulous patients, with no significant difference between fixed restorations and overdentures except on stability, where fixed prostheses scored higher. Within the overdenture group, two implants performed significantly better than one. The attachment systems involved, on studs or on a bar, are described in our guide to implant-retained dentures.
Mini implants, narrower than standard fixtures and quicker to place, are sometimes offered for the same purpose. They are still implants, so the surgical contraindications above apply, and the reduced diameter limits how much load they can carry.
Leaving the gap
Doing nothing is a defensible option in a narrow set of circumstances. A missing back molar, with the teeth in front meeting properly and the opposing tooth stable, may not need replacing at all. That decision should be made at an examination rather than by default, because the drifting described earlier is what turns a simple gap into a complicated one.
| What you are facing | Option to discuss |
|---|---|
| One gap, neighbours untouched | Adhesive bridge |
| One gap, neighbours need crowns | Conventional bridge |
| Several gaps, one arch | Partial denture |
| A whole arch, tight budget | Complete denture |
| Lower denture that moves | Two-implant overdenture |
What the alternatives cost in the UK
NHS dental treatment in England is charged in bands, and crowns, bridges and dentures all sit in Band 3, currently £332.10, whatever the number of units involved in a single course of treatment. Band 1 covers examination, X-rays and a scale and polish at £27.90, and Band 2 covers fillings, root treatment and extractions at £76.60. The other UK nations set their own charges. Some patients pay nothing at all, among them anyone under 18, anyone under 19 in full-time education, and women who are pregnant or have had a baby in the previous twelve months.
Private fees are a different matter and vary widely between practices, which is why quotations are worth comparing item by item rather than on the headline figure. The material of a crown, the alloy of a denture framework, the number of units in a bridge and the review appointments included all move the total.
The cheapest option today is rarely the cheapest over time. A partial denture replaced twice over twenty years, or a bridge that costs you the vitality of two sound teeth, changes the arithmetic. Ask for the expected lifespan, what happens when the restoration fails and which teeth are being committed to the plan.
When the implant is still the right answer: the question becomes where
For a single crown, a bridge or a denture, travelling abroad rarely adds up, since these treatments are available under NHS banding. The calculation changes when the clinical indication points to implants and only the private fee stands in the way.
In Turkey, implant and crown treatment allows savings of up to 70% against private UK fees. Before comparing quotations, check that they cover the same work and the same materials: the number of implants, the brand and reference of the components, the type of crown, any bone grafting, temporary restorations and review appointments. Our guide to choosing a country for dental tourism completes that comparison.
Istanbul, where Body Expert’s partner clinic is based, has teams used to international patients and to the scheduling that treatment from abroad demands. On the Mediterranean coast, Antalya attracts patients who combine treatment with a seaside stay. In either city, what separates one clinic from another is the surgeon’s experience, the traceability of the components used and the way follow-up is organised, far more than the location itself.
A full implant treatment means two stays a few months apart, the interval being the healing time the bone needs. With Body Expert, your visit is built around a five-star hotel stay with breakfast, VIP transfers between the airport, the hotel and the clinic, a dedicated English-speaking patient coordinator throughout and 12 months of post-operative follow-up. Flights remain at your own expense. Whichever clinic you choose, ask how your reviews will be handled once you are home and which records you will be given.
The sensible approach is to have both routes costed before deciding, the prosthetic alternative at home and the implant treatment abroad. For a plan involving several teeth, our teeth care page sets out the treatment pathways available, and a free quotation within 24 hours gives you a figure to compare against, with no obligation.
