Four ways to fill a gap, each with a trade-off no one explains until you've paid.
Tooth replacement means filling the space left by a missing tooth, and there are four routes: a dental implant (replaces the root and helps preserve jawbone), a bridge (fixed, no surgery, supported by neighbouring teeth), a partial denture (removable, lowest cost) or, occasionally, leaving a harmless gap. At our Islington clinic we match the route to your bone, bite and neighbouring teeth.
Visible Signs & Symptoms
A missing tooth is not a static gap. The mouth treats an empty space as a vacancy, and the rest of the mouth slowly reorganises around it. Some changes are visible; many happen quietly over months and years.
Signs that a gap is affecting your mouth
- Drifting and tilting. The teeth either side lean into the space, opening small gaps elsewhere and creating areas that trap food.
- Over-eruption. The tooth in the opposite jaw, with nothing to bite against, slowly grows down into the gap.
- Changes in your bite. Teeth may meet differently, or you may find yourself chewing on one side.
- Uneven wear or sensitivity on the teeth that are now doing more of the work.
- A sunken look to the lip or cheek where several teeth are missing, as the bone beneath shrinks.
- Self-consciousness when smiling or speaking, particularly with a front tooth.
Single, several or many teeth
The situations are different. One missing tooth with healthy neighbours raises different questions from a run of missing back teeth, or from scattered losses across both jaws. Which tooth is missing also matters: a front tooth carries an aesthetic weight that a back molar does not, while a missing molar carries more chewing load.
Teeth that are failing, not yet missing
Many people come to us before a tooth is lost: a tooth that is cracked, loose, repeatedly infected or too broken down to restore. Planning the replacement before the extraction often gives a better result, because bone and gum can be protected from the start and, in some cases, an implant can be placed at the same visit.
Clinical Root Causes
Understanding why a tooth was lost matters, because the same cause can threaten whatever replaces it, and the neighbouring teeth.
Common reasons teeth are lost
- Gum disease. Advanced gum disease destroys the bone that supports teeth, and it is one of the most common causes of tooth loss in adults. It also affects implants, so it must be stable before replacement.
- Decay. Deep decay that reaches the nerve or leaves too little tooth to restore.
- Cracks and fractures. Teeth with large old fillings, or teeth that have been root treated, are more prone to splitting, particularly in people who clench or grind.
- Failed root canal treatment or recurrent infection at the root tip.
- Trauma. Sport, falls and accidents, most often affecting front teeth.
- Congenitally missing teeth. Some adult teeth never develop, commonly the upper lateral incisors or lower premolars, leaving a gap or a retained baby tooth.
Risk factors that shape the plan
- Clenching and grinding. These overload natural teeth and replacements alike; see teeth grinding. A protective splint is often part of the plan.
- Smoking. It slows healing and increases the risk of gum disease and implant complications.
- Diabetes and some medicines. These can affect healing and bone, so we ask about your medical history and liaise with your GP where needed.
- Time since the tooth was lost. Bone shrinks after extraction, so a long-standing gap may have less bone available.
- Hygiene and maintenance. Every replacement depends on the health of the gum around it.
Why missing teeth matter more than they look — the silent consequences
A single missing tooth can start a chain of change. The neighbouring teeth drift, the opposing tooth over-erupts, and a bite that took years to settle begins to shift from one point. That can mean harder cleaning, food trapping, uneven wear elsewhere and, sometimes, overload on the side you now favour. Underneath, the jawbone that held the root begins to shrink, because bone that is no longer loaded by chewing is gradually reabsorbed.
Waiting is not always wrong, but it narrows the options. The longer a gap is left, the more bone may be lost and the more the surrounding teeth may have moved, which can mean grafting before an implant or tooth movement before a bridge.
When leaving a gap is reasonable
Not every gap needs filling. A single missing tooth at the very back, with a stable bite and no opposing tooth over-erupting, may cause no functional harm. In that case we say so, and monitor it at your routine examinations rather than treat it.
When to be seen promptly
- A tooth that is loose, cracked or painful to bite on
- Swelling, a gum blister or a bad taste near a tooth or an existing implant
- A crown, bridge or denture that has come loose or broken
- A front tooth lost through injury, which should be seen the same day if possible
For urgent problems, our emergency appointments are available Monday to Friday.
The four ways to replace a missing tooth — at a glance
There is no single best way to replace a tooth, only the best way to replace your tooth, given how many are missing, where they are, how much bone there is and what you want for the long term.
| Option | Replaces the root | Surgery | Effect on neighbouring teeth | Best suited to | Cost at DWL |
|---|---|---|---|---|---|
| Dental implant | Yes; helps keep the jawbone loaded | Minor surgery, then a few months of healing | None; it stands on its own | A single gap with healthy neighbours and enough bone | From £2,200 including the crown |
| Bridge | No | None; a few appointments | Neighbours are prepared to hold it | Gaps where the neighbouring teeth already need crowns | Quoted in writing after assessment |
| Partial denture | No | None | Clasps or a framework rest on them | Several missing teeth, or an interim step | Quoted in writing after assessment |
| Leaving the gap | No | None | Risk of drifting and over-eruption, so we monitor | A back gap with a stable bite | Monitoring at your routine examination |
Dental implants
An implant is a titanium post placed in the jaw to act as an artificial root, with a crown fitted on top. It is the only option that replaces the root as well as the tooth, which is why it helps keep the jawbone loaded. It stands on its own, so it asks nothing of the neighbouring teeth, and it functions closest to a natural tooth. Placed and maintained well, implants can last many years. The trade-offs: the highest upfront cost, minor surgery, a healing period of a few months, and a need for enough healthy bone. Some patients need bone grafting first. See dental implants.
Bridges
A bridge attaches a replacement tooth to the teeth either side of the gap. There is no surgery and it is usually completed over a few appointments. A conventional bridge involves preparing the neighbouring teeth, so it suits mouths where those teeth already need crowns; where they are healthy and unrestored, an implant is often the more conservative long-term choice. A bridge does not preserve the bone beneath the gap. Our implant versus bridge guide weighs this in detail.
Partial dentures
A removable denture replaces one or several teeth, held by clasps or a discreet framework. It is the lowest-cost route and involves no surgery, which makes it sensible where several teeth are missing, where implants are not suitable, or as an interim step. It moves more than a fixed option, takes some getting used to, and does not preserve bone.
Leaving the gap
Occasionally the honest answer is to replace nothing. Where a gap is at the back, the bite is stable and nothing is drifting or over-erupting, we may recommend monitoring instead. The judgement is never cosmetic alone; it rests on whether the gap will cause harm. Where it will, we replace it. Where it will not, we say so plainly, and you leave with a clear explanation rather than a plan you do not need.
What happens at DWL
Implant assessment, planning and placement are with Dr Rishil Patel, who holds an MClinDent in Implantology and whose special interests are oral surgery and dental implants. Planning uses a 3D scan so the implant sits clear of nerves and sinuses. Bridges, crowns, dentures and the overall smile plan are with Dr Vishal Patel. Before choosing, we check gum health, the bite, the jaw joints and any grinding, because a new tooth placed into an unstable or overloaded bite is how good work fails early. We choose with you using a handful of questions: which tooth, how many, how much bone, the health of the neighbours, your timeline and budget, and what you want in twenty years. Results vary, and we explain the risks of each route. If you are local, see our page on dental implants in Islington.

View all FAQs →What is the best way to replace a missing tooth?
There is no single best way — there is the best way for your mouth. A dental implant lasts longest and is the only option that preserves the jawbone. A bridge can be better when neighbouring teeth already need work, and a denture is sensible when several teeth are missing or cost rules out surgery.
How much does it cost to replace a tooth in the UK?
It depends on the route. A single implant is from £2,200 including the crown, a bridge is quoted in writing after assessment depending on span and material, and partial dentures are the lowest-cost option. Every option is itemised in writing before you commit, and finance is available through Tabeo, subject to status.
Can the NHS replace missing teeth?
The NHS does provide tooth replacement, most commonly dentures and, in limited circumstances, bridges, where there is a clinical need. Implants are very rarely available on the NHS and only in specific medical cases.
How long do dental implants last compared with bridges?
A well-placed and well-maintained implant can last twenty to thirty years and often longer, because it replaces the root and keeps the bone loaded. A bridge typically lasts ten to fifteen years, partly because it relies on the neighbouring teeth and does not preserve the bone beneath the gap.
Can I replace multiple missing teeth at once?
Yes. Several gaps can be addressed with multiple implants, an implant-supported bridge or All-on-4, a longer conventional bridge, or a partial denture, depending on where the teeth are and how much bone remains. Replacing several teeth at once is often more efficient and gives a more stable result.
What happens if I don't replace a missing tooth?
Sometimes nothing of concern — a back gap with a stable bite may be fine left alone. But often the neighbouring teeth drift and tilt into the space, the opposing tooth over-erupts, the bite shifts, and the jawbone beneath the gap shrinks over time.
Is tooth replacement painful?
Most routes are comfortable. Bridges and dentures involve no surgery. Implant placement is done under local anaesthetic so the procedure itself is not painful, and most people manage the healing period with ordinary pain relief.
Can I get implants if I have bone loss?
Often, yes — but it may need a step first. Where the jawbone has shrunk, bone grafting can rebuild enough volume to anchor an implant, and in some cases the post can be angled to use the bone you still have. A 3D scan tells us exactly how much bone is there and whether grafting is needed.
