Dental Implants vs Bridge — Which Is Best for a Single Tooth?
This page is for anyone comparing a dental implant vs bridge for a single tooth. It covers the tooth-preparation trade-off, lifespan evidence, bone preservation, and cost over time. Core takeaway: the right answer depends on the condition of your adjacent teeth, your bone, and how far ahead you are planning.

The key differences at a glance
For a single missing tooth, an implant avoids touching the adjacent teeth, while a bridge is faster and cheaper upfront but permanently prepares two healthy neighbours.
The comparison table below breaks this down across the five dimensions that actually drive the decision — adjacent teeth, lifespan, bone, treatment time, and cost.
| Dimension | Single tooth implant | Conventional fixed bridge |
|---|---|---|
| Affects adjacent teeth | No — stands alone in the gap | Yes — both neighbouring teeth are permanently prepared and crowned |
| Published 10-year survival | Implant-level ~93–96% across recent systematic reviews | Prosthesis survival ~89% (European systematic reviews, Pjetursson et al. 2004) Abutment tooth survival ~72% at 10 years (UK General Dental Services, Lucarotti & Burke 2012) |
| Bone beneath the gap | Loaded through the fixture — helps maintain alveolar bone | Not loaded — bone under the pontic tends to continue resorbing over time |
| Typical treatment duration | 3–6 months from placement to final crown (longer with grafting) | 2–3 weeks across 2–3 visits |
| Upfront cost in the UK | Generally higher — single tooth implants from £2,400 at our practice | Generally lower upfront; bridge pricing depends on number of units and material — discussed at consultation |
| Cost over 20–25 years | Fewer replacement cycles typically expected | A meaningful proportion require re-treatment within that window |
| NHS availability (England) | Not routinely available — rare exceptional cases only | Available on the NHS under Band 3 (£326.70 from 1 April 2025) |
No column wins every row. The right choice depends on which rows matter most to you — and on what your adjacent teeth currently look like.
Single tooth implant — what you need to know
A single tooth implant (the titanium fixture placed in the jawbone) replaces the entire missing tooth, root and all, and is topped with a crown after healing.
Many patients who enquire about a single tooth implant are not just asking what it is — they want to know whether it is the right choice for their specific gap, their neighbours, and their bone. That second question is the one a consultation is designed to answer.
After placement, the fixture osseointegrates — bone cells grow onto the implant surface so it becomes structurally anchored. You can read more about the biology in our page on osseointegration and how dental implants fuse with bone. Because the implant sits independently in the gap, the two adjacent teeth are not touched.
On lifespan, recent systematic reviews of single-tooth implants report implant-level survival around 95% at 10 years, with the original crown on top surviving around 89% at the same follow-up (Hjalmarsson et al., 2016). A 2019 meta-analysis of prospective 10-year studies reported 96.4% (95% CI 95.2–97.5%) at the implant level, with a more conservative sensitivity estimate of 93.2% (Howe, Keys & Richards, 2019). Longer 20-year data is more limited and shows some variation between prospective and retrospective analyses. These are population estimates — individual outcomes depend on bone quality, gum health, smoking, general health, and maintenance.
The main trade-offs are a longer overall treatment (typically 3–6 months), a higher upfront cost, and the requirement for enough bone to support the fixture — bone augmentation is sometimes needed first.
Conventional bridge — what you need to know
A conventional bridge (a fixed restoration spanning the gap) replaces one missing tooth by cementing crowns onto the two adjacent teeth and joining them via a pontic.
To fit those crowns, the dentist has to permanently remove healthy enamel and dentine from both neighbouring teeth — and once prepared, those teeth are committed to restorations for the rest of their working life. This is the single most important point patients often don't realise until after the fact, and it is why we have a separate in-depth discussion of how bridge preparation affects healthy adjacent teeth.
On lifespan, European systematic reviews of fixed partial dentures (bridges) report a 10-year prosthesis survival of around 89%, with roughly 71% of patients free of complications at 10 years (Pjetursson et al., 2004). UK real-world data from the General Dental Services tells a more sober story: conventional bridge abutment teeth showed around 72% survival at 10 years (Lucarotti & Burke, 2012). Across the observation period in the Pjetursson 2004 systematic review, loss of pulp vitality in abutment teeth was the most common biological complication (~32.6%), followed by caries at abutment teeth (~9.1%) — each of these risks can trigger further work down the line.
In clinical practice, most of the problems that shorten a bridge's working life are related to what happens at the abutment teeth rather than to the bridge span itself — which is why the condition of those two neighbouring teeth at the start of treatment is the strongest single predictor of how the restoration will hold up. Most issues are manageable when identified early at routine check-ups.
The advantages are real: a bridge is non-surgical, treatment is typically complete within 2–3 weeks, and if the adjacent teeth are already heavily filled or broken down and need crowns anyway, using them as bridge supports is often the sensible clinical choice.

Bone preservation: the structural difference
An implant loads the bone beneath the missing tooth each time you chew; a bridge does not, so the bone beneath the pontic tends to continue resorbing over time.
Natural tooth roots stimulate the alveolar bone through functional loading — this is what maintains its volume. When a tooth is extracted, that stimulus is lost and the bone begins to remodel and shrink. An implant fixture, once integrated, transmits occlusal load into the bone and helps maintain ridge volume at that site. A bridge pontic sits above the gum and does not load the underlying bone at all, so resorption beneath the pontic tends to continue gradually over the years. Over a decade or two, this can become visible as a change in the ridge profile beneath the bridge. A bridge cannot match this — but it is not, on its own, a reason to reject one.
Cost over time: the per-decade view
Upfront, a bridge is usually cheaper; across 20–25 years, the picture often narrows or reverses because replacement cycles and abutment complications add up.
Our current implant pricing starts from £2,400 per single tooth implant, with the implant consultation at £100 (redeemable against treatment) and the CBCT planning scan at £150 — the current fee guide is available on our dental implant cost page. Because every case is different, a full written estimate is only given after assessment.
Thinking in decades changes the conversation. A meaningful proportion of conventional bridges require re-treatment within a 20–25 year window — which is consistent with the UK GDS abutment survival data cited above — and the cumulative cost can approach, and in some scenarios exceed, the cost of an implant that stays in place. Add the possibility of abutment complications (pulp loss, caries at the crown margin, abutment fracture) and the long-run cost picture often favours the implant even before bone preservation is considered. The opposite is true if your life planning horizon is shorter or if the adjacent teeth already needed crowning for other reasons.
For patients who want to move forward without paying the full amount upfront, we offer Tabeo finance — up to 18 months interest-free, or up to 60 months at 10.9% APR representative. Details are on our implant finance page.

Which option suits which patient?
The right choice depends on the condition of your adjacent teeth, your bone volume, your medical history, and how long you are planning ahead.
- If the teeth either side of the gap are completely healthy and unrestored → an implant is usually the more conservative long-term option, because it avoids cutting into untouched teeth.
- If the teeth either side of the gap already need large restorations or crowns → a bridge can be the sensible choice, because those teeth are going to be prepared anyway and the bridge uses that preparation.
- If you have reduced bone volume at the site → grafting may be needed before an implant; a bridge may be simpler in the short term, though it does not address bone loss beneath the pontic.
- If you have medical factors that make oral surgery higher risk (uncontrolled diabetes, certain bisphosphonate regimens, recent head-and-neck radiotherapy) → a bridge may be safer, and the implant decision should be deferred until assessed in detail.
- If you are a heavy smoker → implant survival is reduced, and the decision benefits from a frank conversation about risk rather than a default choice.
- If your planning horizon is long (you want one decision that lasts) → an implant is generally the option most aligned with that goal, provided the clinical factors support it.
- If your planning horizon is short or you have specific life constraints → a bridge's 2–3 week treatment window can be the deciding factor when an implant timeline of 3–6 months is not workable.
None of these points can be settled without a clinical examination and, for implants, a CBCT scan to confirm bone volume. If you want to understand the wider picture before making a decision, you can explore whether dental implants could work for you across the full range of clinical situations we treat.
Cost framing: NHS versus private
Bridges are available on the NHS under Band 3 (£326.70 from 1 April 2025); dental implants are not routinely NHS-funded in England, so patients seeking them typically access treatment privately.
Private UK bridge prices vary widely depending on materials and practice, and our own fees are discussed case-by-case because bridge cost depends on the number of units, the material chosen, and the condition of the supporting teeth. At Deepcar Dental Care, single tooth implants start from £2,400, and a full itemised estimate is provided after your consultation. Current fees are maintained on our fee guide.
Questions, answered
Frequently asked questions
Is an implant always better than a bridge for a single tooth?
No — "better" depends on your situation. An implant is often the more conservative long-term choice because it avoids cutting into healthy adjacent teeth, but a bridge can be the sensible answer when the neighbours already need crowns, when surgery is not advisable, or when the 3–6 month implant timeline is not workable.
Does a bridge really damage the adjacent teeth?
Adjacent tooth preparation for a conventional bridge permanently removes enamel and dentine from both abutment teeth. That preparation is irreversible, and Pjetursson's 2004 systematic review reports loss of pulp vitality in around a third of abutment teeth as the most common biological complication over the observation period.
How long does a single tooth implant last compared to a bridge?
Recent systematic reviews put single-tooth implant survival around 93–96% at 10 years, with the crown on top surviving around 89%. Conventional bridges sit around 89% at 10 years in European reviews, and closer to 72% abutment survival at 10 years in UK General Dental Services data. Individual outcomes vary with bone quality, smoking, and maintenance.
Can I get a dental implant on the NHS in England?
Dental implants are not routinely available on the NHS. Funding is restricted to exceptional cases — for example, tooth loss from trauma, oral cancer, or congenital absence — and decided through specialist referral. Most patients who want an implant access treatment privately. NHS bridges fall under Band 3 (£326.70 from 1 April 2025).
Which option preserves bone better?
An implant transmits chewing load into the jawbone, which helps maintain alveolar bone volume at the site; a bridge does not load the bone beneath the pontic, so that bone tends to continue resorbing gradually over time. This is one of the strongest clinical arguments in favour of implants when bone preservation matters.
