Full-Mouth Comparison
All-on-4 vs Individual Implants
Honest comparison of full-arch and per-tooth implant solutions for patients facing significant tooth loss. Last reviewed April 2026.
The short answer
All-on-4 uses 4 implants per arch to support a complete bridge of 10-12 teeth — designed for patients missing most or all of their teeth in an arch. Individual implants replace teeth one at a time. They are not direct alternatives: All-on-4 is for full-arch restoration (typical cost from £14,000 per arch at Tower Dental); individual implants are for replacing a small number of teeth (£2,380 each). The choice is determined by how many natural teeth you are keeping, the condition of your remaining bone, and your overall clinical situation. For full-arch tooth loss, All-on-4 is typically half the cost of placing individual implants for every missing tooth.
When each option applies
The clinical question that decides between these two options is: how many teeth are you keeping in this arch? If you are keeping most of your natural teeth and need to replace 1-4 missing or failing teeth, individual implants are the standard recommendation. If you are missing most or all teeth in an arch — or your remaining teeth are failing and will need extraction anyway — full-arch reconstruction with All-on-4 becomes the more appropriate option.
There is rarely a meaningful overlap between these scenarios. A patient missing 6 teeth in an arch with 4-6 healthy teeth remaining would normally have individual implants for the missing teeth, not full-arch reconstruction. A patient with all teeth failing or missing rarely benefits from placing 10-12 individual implants when 4 strategically placed implants can support the whole arch.
How All-on-4 works
All-on-4 uses a specific biomechanical principle: four implants strategically angled and positioned in the front and middle of the jaw can support a fixed bridge of 10-12 teeth. The two front implants are placed vertically; the two back implants are placed at a 30-45 degree tilt, which lets them engage denser bone in the front of the jaw and distributes chewing forces across a wider area.
The procedure typically takes one surgical appointment per arch (3-4 hours under local anaesthetic, sometimes with sedation). Any remaining failing teeth in the arch are extracted at the same time, the four implants are placed, and a temporary fixed bridge is attached the same day. The patient leaves the practice with a full set of teeth — not dentures — and returns 3-6 months later for the final permanent bridge once the implants have integrated with the bone.
The "same-day teeth" aspect is one of the main psychological advantages of All-on-4 — patients do not have to spend months in dentures while waiting for implants to heal.
How individual implants work
Each individual implant replaces a single missing tooth. The titanium fixture is placed in the bone where the tooth root used to be, given 3-6 months to integrate with the bone, then a single crown is fitted on top. For a patient missing one tooth, this is one implant and one crown. For a patient missing three non-adjacent teeth, it is three separate implants, each with its own crown.
The advantage of individual implants is that they preserve the independence of each tooth — there are no connected bridges to floss under, no shared structural failure points, and a problem with one implant doesn't affect any others. The disadvantage is cost and time: each implant is a separate procedure, separate cost, and separate healing period.
Side-by-side comparison
| Factor | All-on-4 (per arch) | Individual Implants (full arch, 10-12 teeth) |
|---|---|---|
| Cost (Tower Dental) | From £14,000 | £23,800-£28,560+ (10-12 × £2,380) |
| Number of implants | 4 per arch | 10-12 per arch |
| Surgery | 1 session per arch (3-4 hours) | 10-12 sessions, may span months |
| Same-day teeth? | Yes (temporary bridge fitted same day) | No (typically gap-by-gap healing) |
| Bone graft requirement | Often avoidable due to angled placement | Often required for back teeth |
| Healing time to final bridge | 3-6 months | 3-6 months per implant |
| Lifespan (implants) | 25+ years | 25+ years |
| Bridge / crown lifespan | 10-15 years (one bridge) | 10-15 years (per crown) |
| Cleaning | Around the bridge with special tools | Like natural teeth — brush and floss |
| Best when | Most or all teeth missing in an arch | 1-4 teeth missing in otherwise sound mouth |
The cost picture honestly
For full-arch tooth loss, All-on-4 is meaningfully cheaper than placing individual implants for every missing tooth. Compare:
- All-on-4, single arch: from £14,000 — covers 4 implants, full fixed bridge of 10-12 teeth, all surgery, all temporary work
- Individual implants, full arch (12 teeth): approximately £28,560 (12 × £2,380) — and this is before any necessary bone grafting
- Bone grafts (often needed for individual implants in back of mouth): £400-£1,500 per site
For most patients facing full-arch tooth loss, the cost difference is £10,000-£15,000 in favour of All-on-4 — and that doesn't account for the additional complexity, surgical time and recovery of placing 10-12 individual implants. This is why All-on-4 has become the standard recommendation for full-arch restoration when the alternative would have been a full denture or a long sequence of individual implants.
Trade-offs nobody mentions in the marketing
All-on-4 has real advantages but also real trade-offs that marketing literature tends to gloss over. Honest list:
- You cannot replace one tooth at a time. If a single tooth on the bridge breaks, the bridge needs to be repaired or replaced as a unit.
- Cleaning is different. The bridge has a small space underneath where it meets the gum, and this requires specific cleaning tools (water flosser, threader floss, special brushes). Most patients adapt within a few weeks but it is a learning curve.
- One implant failure can affect the whole bridge. If one of the 4 implants fails (rare but possible), the bridge cannot be supported reliably until the implant is replaced. Individual implants are independent — one failure doesn't affect others.
- Speech can change initially. Some patients find it takes 1-2 weeks for their tongue to adapt to the new tooth positions, particularly for sounds like 's' and 'th'. This usually resolves quickly but is a real adjustment.
- It is not reversible. Once the natural teeth are extracted, the path back is to dentures or to redo the implant work.
None of these are deal-breakers — patients are overwhelmingly happy with All-on-4 results — but they should be discussed before treatment, not after.
Who All-on-4 is genuinely for
- Patients missing most or all teeth in an arch (upper, lower, or both)
- Patients whose remaining teeth are all failing and will need extraction anyway
- Long-term denture wearers ready for a fixed solution
- Patients with significant bone loss who could not have full-arch individual implants without extensive grafting
- Patients who want a "one and done" surgical solution rather than years of individual implant work
Who should stick with individual implants
- Patients keeping most of their natural teeth
- Patients missing 1-4 teeth in an otherwise sound arch
- Patients whose remaining teeth have a good long-term prognosis
- Patients who value tooth-by-tooth independence and natural-feeling cleaning
Bottom line
All-on-4 and individual implants solve different problems and aren't really alternatives to each other for the same case. All-on-4 is the right answer for full-arch tooth loss; individual implants are the right answer for replacing a small number of teeth. The choice is determined by your specific clinical situation, not by what looks more attractive in marketing materials.

Frequently Asked Questions
How is All-on-4 different from individual implants? +
All-on-4 uses just four titanium implants per arch (upper or lower) to support a complete fixed bridge of 10-12 teeth. Individual implants replace teeth one at a time, with one implant per missing tooth. The two are different solutions for different problems: All-on-4 is designed for patients missing most or all of their teeth in an arch, where placing 10-12 individual implants would be too costly, too invasive, and often clinically impossible due to insufficient bone. Individual implants are appropriate when you have most of your teeth and need to replace one or several.
Is All-on-4 cheaper than individual implants? +
Significantly. At Tower Dental Blackpool, All-on-4 starts from around £14,000 per arch — a fixed full-arch solution using 4 implants. Replacing all 12 teeth in an arch with individual implants would cost roughly £28,560 (12 × £2,380) just for the implants and crowns alone, before accounting for any necessary bone grafting. All-on-4 is therefore approximately half the cost of full-arch individual implants — and is often the only realistic option for patients with significant bone loss who would need extensive grafting before individual implants could be placed.
How many teeth can All-on-4 replace? +
A single All-on-4 procedure replaces an entire dental arch — typically 10-12 teeth. The full bridge is supported by just 4 implants strategically placed to maximise the use of available bone. Some patients have All-on-4 in just one arch (usually the upper) and keep their natural lower teeth; others have All-on-4 in both arches if all natural teeth need replacing. The result is a complete fixed set of teeth that look and function like natural teeth and don't need to be removed for cleaning.
Can I have All-on-4 if I've lost a lot of bone? +
Yes — this is one of the main reasons All-on-4 was developed. The procedure uses a specific implant placement angle (typically 30-45 degrees on the back two implants) which allows them to engage areas of bone that conventional vertical implants cannot reach. This means many patients who would have needed extensive bone grafting for individual implants can have All-on-4 without any grafting at all, or with minimal grafting. The pre-treatment CT scan determines whether your bone is suitable; patients who have been wearing dentures for many years often still qualify.
Is All-on-4 surgery more invasive than individual implants? +
All-on-4 is more invasive in a single sitting but less invasive overall. The procedure involves removing any remaining failing teeth, placing 4 implants and fitting a temporary bridge — all in one surgical appointment, typically 3-4 hours per arch. Individual implants can be placed in shorter appointments but require many separate procedures over months or years. Patients tell us they prefer All-on-4 for the 'one and done' aspect, despite the longer surgical session. Recovery from All-on-4 takes 7-10 days for soft tissue healing, with full integration over 3-6 months while you wear the temporary bridge.
How long does All-on-4 last? +
Well-placed All-on-4 implants typically last 25+ years — the same as individual implants — because the underlying titanium fixture is identical. The bridge attached to the implants may need replacement after 10-15 years due to wear, particularly for patients who grind their teeth. Most All-on-4 cases are designed so that if the bridge needs replacing, the implants can be reused with a new bridge, keeping the cost of any future work much lower than the original treatment.
Can the bridge be removed for cleaning? +
No, and this is intentional. The All-on-4 bridge is fixed to the implants permanently and behaves like natural teeth — you brush and floss around it the same way. Some patients confuse All-on-4 with 'implant-retained dentures', which are removable. All-on-4 is not removable. The bridge is designed with cleansable contours and your hygienist will guide you through the specific cleaning routine, which usually involves a special brush, floss threaders, and a water flosser. The bridge itself is screw-retained, so a dentist can remove and refit it for any deeper maintenance, but you cannot take it out at home.
Should I choose individual implants instead? +
Individual implants are the right choice if you have 1-3 missing teeth in an otherwise healthy mouth, where the surrounding teeth and bone are sound. They preserve the integrity of your natural dentition and don't require removing any healthy teeth. All-on-4 only makes sense if you are missing most or all teeth in an arch, or if all your remaining teeth are failing and would need extraction anyway. We do not recommend All-on-4 for patients who could keep most of their natural teeth — extracting healthy teeth to fit a full-arch bridge is rarely the right clinical choice.
