All-on-6 replaces all the teeth in one jaw with a fixed bridge held by six implants instead of four. It is a private treatment in the UK, and the clinic prices we found start at £15,000 to £15,500 per arch, with one clinic putting the usual UK range as high as £40,000 per arch. This guide sets out what named clinics publish, what research says about four implants against more than four, and what to check in a quote.
Every price below links to the clinic page it comes from, and we checked each page in October 2026. Clinic pages are marketing as well as information. Use them as a guide when you compare quotes; the fee in your written treatment plan is what counts.
What is the difference between All-on-6 and All-on-4?
The difference is the number of implants that carry the bridge. All-on-4 is a defined protocol: a 2017 systematic review describes two front implants placed straight and two back implants placed further back and angled to minimise the cantilever, the part of the bridge that hangs unsupported. A 2026 systematic review explains that this approach can avoid extensive bone grafting where there is little bone behind the premolars.
All-on-6 adds two more implants. Clinics market it for extra support: The Gentle Dental in East Molesey, Surrey, says its implantologist offers All-on-6 for patients who need extra stability to support their prosthetic. Whether you have enough bone for six implants, and whether you need them, is decided from your CBCT scan.
Is All-on-6 better than All-on-4?
The research does not show a clear winner. The 2026 review compared All-on-4 with fixed bridges on more than four implants. It included eleven All-on-4 studies and nine studies of the alternatives:
| Outcome | All-on-4 | More than four implants |
|---|---|---|
| Prosthesis survival (over up to 20 years) | 85.0 to 100% | 88.2 to 100% |
| Implant survival | 89.7 to 97.9% | 98.9 to 99.0% |
| Marginal bone loss after 5 years | Up to 1.9 mm | Up to 2.9 mm |
Source: 2026 systematic review of the All-on-Four concept. The authors conclude that All-on-4 is a predictable option with implant and prosthetic survival comparable to concepts with more than four implants.
A 2016 meta-analysis of implant-supported prostheses in toothless jaws, which included 54 studies, points the other way for the lower jaw: four implants with a fixed restoration in the mandible had significantly higher implant loss rates than five or more implants with a fixed restoration. It also found that implant loss rates were higher in the upper jaw than in the lower jaw.
What this means for you: more implants is not automatically better, and fewer is not automatically worse. Ask your surgeon why they recommend four or six for your jaw, and what the plan is if one implant fails.
How much does All-on-6 cost in the UK?
These are the figures named clinics publish:
| Clinic | What the page publishes | What to note |
|---|---|---|
| The Gentle Dental (East Molesey, Surrey) | From £15,500 for a single arch | Includes six implants and abutments, temporary teeth, the full bridge, surgery and follow-up. Consultation, scans and maintenance can be extra. |
| London City Smiles | All-on-6 offer at £15,000 (usually £18,000) | An offer price, so check the end date and what it covers. |
| Globe Dental Practice (Nantwich) | All-on-4 and All-on-6 from £12,000 for a single arch; full mouth packages from £20,900 | The same page says All-on-6 tends to sit between £20,000 and £40,000 per arch across the UK. |
The Gentle Dental also gives its view of UK prices: minimum costs per arch often starting at £15,000 and reaching £22,000, and £30,000 to £40,000 for both arches. It warns that if a clinic offers All-on-6 for as little as £11,000, you should check what is included, because temporary teeth may be charged on top. For more on what changes the price, see our implant brand comparison and city guides for London, Manchester and Leeds.
What does finance add?
The Gentle Dental publishes finance examples for its £15,500 All-on-6 price: 12 months at 0% is £1,291 a month, and 60 months at 9.9% is £325.35 a month. Always ask for the total repayable as well as the monthly figure. Our finance guide explains how to compare offers.
Which bridge material should you choose?
Zirconia bridges cost more, and the evidence leans slightly in their favour. The Gentle Dental lists zirconia costing more than acrylic as one reason prices differ. A 2026 meta-analysis of twelve studies compared metal-zirconia and metal-acrylic full-arch bridges. It found a more favourable clinical profile for metal-zirconia, particularly for prosthetic wear, peri-implantitis and marginal bone loss, with comparable overall survival. Most of the studies had moderate to critical risk of bias, so treat the result with caution.
Who is All-on-6 suited to?
All-on-6 is for people who have lost, or are about to lose, all the teeth in one jaw and have enough bone for six implants. If bone is limited at the back of the jaw, the angled implants of All-on-4 are designed to avoid extensive grafting, and severe upper jaw bone loss may lead to zygomatic implants. A bone graft is another route. The Gentle Dental says bone grafting or sinus lifting might be recommended where bone has broken down severely.
Can you get All-on-6 on the NHS?
Almost never. The NHS says implants are usually only available privately, and that, although it is rare, they are sometimes available on the NHS for patients who cannot wear dentures for certain reasons, such as mouth cancer or an accident. The NHS alternative for a toothless jaw is complete dentures, which are a Band 3 treatment. The NHS charges page lists Band 3 at £332.10 in England. See our guide to NHS dental implants.
What should you check before you book?
- Is the price per arch, and does it include the final bridge as well as the temporary one?
- Which bridge material is quoted, and what does the alternative cost?
- Are the consultation, scans, sedation, extractions and follow-up visits included?
- Why does the surgeon recommend six implants for you rather than four, or the other way round?
- What happens, and what does it cost, if an implant fails or the bridge breaks?
- What is the total repayable on finance?
In England you can read a practice’s inspection reports through the Care Quality Commission, which says it inspects 10% of dentists in England each year and does not give ratings to dentist services. Anyone can search the General Dental Council register to check the dentist is registered. Our consultation guide has more questions, and our full-arch guide compares the options side by side.
Frequently asked questions
How much does All-on-6 cost in the UK?
The clinic prices we found start at £15,000 (a London City Smiles offer, usually £18,000) and £15,500 per arch (The Gentle Dental). Globe Dental Practice in Nantwich starts All-on-4 and All-on-6 from £12,000 per arch. For both arches, The Gentle Dental puts the UK range at £30,000 to £40,000.
Is All-on-6 better than All-on-4?
Not clearly. A 2026 systematic review found prosthesis survival comparable between All-on-4 (85.0 to 100%) and fixed bridges on more than four implants (88.2 to 100%). A 2016 meta-analysis found higher implant loss with four implants than with five or more in the lower jaw. Your bone and your surgeon’s reasoning decide which suits you.
What is included in an All-on-6 price?
It varies. The Gentle Dental lists six implants and abutments, temporary teeth, the full bridge, digital smile design, the surgery and follow-up appointments, and says the consultation, scans and maintenance can be extra. Ask every clinic for the same itemised list.
Is All-on-6 available on the NHS?
Rarely. The NHS says implants are usually only available privately, and are sometimes available on the NHS for patients who cannot wear dentures for reasons such as mouth cancer or an accident. Complete dentures are the usual NHS option, charged at Band 3.
Is a zirconia bridge worth the extra cost?
A 2026 meta-analysis found that metal-zirconia full-arch bridges had a more favourable profile than metal-acrylic ones for wear, peri-implantitis and bone loss, with similar overall survival. The studies were mostly at moderate to critical risk of bias, so ask your clinic what each option costs to repair.
