All on 4, Implant Dentures or Dentures? Your Complete Guide — Leicester & Corby (2026)

17th March 2026

Comparing dentures vs implant-retained dentures vs All-on-4 in Leicester and Corby? This complete 2026 guide breaks down every option — costs, function, longevity and aesthetics — so you can make the right decision for your smile.

Losing most or all of your teeth is one of the most significant things that can happen to your oral health — and to your confidence. But the good news is this: you have more options than ever before. The challenge is understanding what those options actually mean in practice, and which one is right for you.

From conventional full dentures to the most advanced all-ceramic fixed implant bridges, this guide walks you through all four main ways of replacing a full arch of missing teeth. We explain what each involves, what it costs in Leicester and Corby in 2025, and — most importantly — what it actually feels like to live with.

At Natural Smiles, with clinics in Wigston, Leicester and Corby, Northamptonshire, we believe that an informed patient makes a better patient. So here is everything you need to know — no jargon, no sales pressure, just straight answers.

The Four Options Explained

Option 1: Full Denture (no implants)

A conventional full denture is an acrylic plate carrying a complete set of artificial teeth that rests directly on the gum. It is held in place by suction — or, in many cases, by denture adhesive. It is removed at night for cleaning and soaking.

Full upper & lower dentures

For generations, full dentures were the only option for patients who had lost all their teeth. They remain a valid choice for patients who cannot or do not wish to undergo surgery, or who face significant budget constraints. However, they come with well-known limitations: they move during eating and speech, they restrict diet significantly, and — critically — they do nothing to prevent the bone loss that begins the moment teeth are extracted. Over years, this bone loss causes the characteristic ‘sunken’ facial appearance that becomes increasingly difficult to reverse.

Option 2: Implant-Retained Denture

An implant-retained denture (also called an overdenture or snap-on denture) uses 2–4 dental implants to anchor a conventional-style denture firmly in place. The denture clips or snaps onto the implants, eliminating the movement and instability of conventional dentures.

This is a life-changing upgrade for patients who have struggled with conventional dentures. Eating becomes dramatically easier, speech improves, and patients no longer need adhesive. The denture is still removed at night for cleaning — but during the day it behaves as a stable, secure set of teeth. The implants also begin to preserve bone at the points where they are placed, slowing the resorption process.

It is particularly well-suited for patients making the transition from conventional dentures, or those with limited bone volume who might not be immediately suitable for full fixed implant treatment.

Option 3: All-on-4/6 — FP3 (Fixed Hybrid Bridge)

The All-on-4 technique uses four to six strategically placed implants to support a complete arch of teeth that is permanently fixed in the jaw — not removable by the patient. FP3, in the Misch prosthetic classification, means the bridge replaces both the missing teeth and the missing gum tissue. The teeth sit within a pink acrylic base that recreates the natural appearance of gum.

FP3 is particularly appropriate where significant gum volume has been lost — which is common in patients who have been wearing dentures for years or who have had tooth loss accompanied by gum recession. The pink acrylic base compensates for this lost tissue, providing natural lip support and a full, natural-looking smile.

In many cases, implants can be placed and temporary fixed teeth fitted on the same day — which is why this is often called ‘teeth in a day’ or ‘smile in a day’. The permanent bridge is fitted after the healing period of six to nine months. Both our Leicester and Corby practices offer this treatment.

Option 4: All-on-4/6 — FP1 (Fixed Full-Ceramic Bridge)

FP1 is the gold standard in full-arch implant dentistry. Like FP3, it uses four to six implants to support a fully fixed bridge — but in FP1, the prosthesis replaces teeth only. There is no pink acrylic. The crowns are made entirely from high-strength ceramic or zirconia, and they are framed by the patient’s own real gum tissue, which has been carefully managed and preserved throughout treatment.

The result, when done well, is truly indistinguishable from natural teeth — in appearance, feel, and function. Chewing efficiency approaches 100% of natural dentition. Cleaning is straightforward. The ceramic is highly durable, and the bridge can last 20 or more years with proper maintenance.

FP1 typically requires more bone volume and better soft tissue conditions than FP3 — meaning it may involve more preparation, including bone grafting, and a longer treatment timeline. The investment is higher, but for patients who are good candidates, it represents the most complete restoration available in dentistry today.

The 20-Year True Cost Argument — Why Cheaper Isn’t Always Cheaper

One of the most powerful conversations we have with patients at Natural Smiles is about the true cost of each option over time — not just the upfront price, but what you actually spend over 20 years.

Which Option Is Right for You?

There is no single ‘best’ option — the right choice depends entirely on your clinical situation, your goals, and your budget. What we can tell you is that no patient at either our Leicester or Corby clinic should feel limited to conventional dentures simply because they don’t know the alternatives exist.

Consider a full denture if…

• You have significant medical contraindications to surgery
• You are not in a position to undergo implant treatment at this time
• Budget is the primary constraint and you understand the long-term trade-offs

Consider an implant-retained denture if…

• Your existing dentures are unstable and affecting your quality of life
• You want a meaningful step-up in stability without committing to fully fixed teeth
• You have limited bone volume and a smaller surgical procedure is preferable
• You are considering this as a stepping stone towards a fixed solution

Consider All-on-4/6 FP3 if…

• You want fully fixed teeth that you never remove
• Significant gum volume has been lost and needs to be replaced aesthetically
• You want same-day teeth and the fastest route to a functional, natural-looking smile
• This is our most popular full-arch solution — and for most patients, an outstanding outcome

Consider All-on-4/6 FP1 if…

• You want the most natural-looking, most functional result available in dentistry today
• You have — or are willing to invest in building — sufficient bone and soft tissue
• You want the lowest long-term maintenance cost and the most durable restoration
• You are a non-smoker in good general health

Ultimately, these options may not be available to all patients; as it is dependent on how much gum, bone and face height changes have occurred over the years. The more damage or delay in your treatment the less likely FP1 will be available as an option

How Natural Smiles Approaches Full-Arch Implant Treatment

Every full-arch implant journey at Natural Smiles — whether at our Wigston, Leicester clinic or our Corby clinic — begins the same way: with a thorough clinical assessment, 3D CT scanning, and an honest conversation about which option is genuinely right for you.

Our implant clinician, Dr Bhavnish Waghela has been placing implants since 2005, training under world-class surgeon Dr Ashok Sethi on Harley Street, before completing the Diploma in Implant Dentistry at the Royal College of Surgeons of England — one of the most respected implant qualifications in the UK. That foundation, combined with ongoing advanced training worldwide, underpins every case we treat.

We work with top-tier dental technicians whose craftsmanship in fabricating your final crowns and bridge is as important as the surgical placement itself. The combination of surgical precision and exceptional laboratory work is what elevates results from good to outstanding.

We also offer 0% APR finance through Medenta and V12 Retail Finance — making full-arch treatment manageable for patients across Leicester, Corby, and the surrounding area.

Frequently Asked Questions

Can I have fixed implant teeth if I’ve been wearing dentures for many years?

In most cases, yes — though the length of time you have worn dentures affects how much bone has been lost. Patients who have worn dentures for many years often require bone grafting or are better suited to FP3 (where the pink acrylic compensates for the lost bone and gum volume). A CBCT scan at your consultation will give us the full picture.

What is the difference between FP1 and FP3?

Both are fully fixed implant bridges — the patient cannot remove them. FP3 replaces both teeth and gum tissue (using pink acrylic). FP1 replaces teeth only, with the patient’s own real gum tissue framing the teeth. FP1 is more natural-looking but requires better biological conditions.

How long does All-on-4 treatment take?

In many cases, implants are placed and temporary fixed teeth fitted on the same day. The permanent bridge is then made and fitted after the healing period — typically three to nine months for FP3, and potentially longer for FP1. Your full timeline will be discussed at your consultation at either our Leicester or Corby clinic.

Is the treatment painful?

Implant placement is carried out under local anaesthetic, so there is no pain during the procedure. Most patients are surprised by how comfortable the process is. Post-operative soreness is normal for a few days and is manageable with standard over-the-counter pain relief. IV sedation is available for anxious patients.

IV sedation — a deeper level of comfort for anxious patients.

For patients who feel particularly anxious about dental treatment, we offer intravenous (IV) sedation administered by Dr Bhavnish Waghela. With IV sedation, you remain conscious and able to respond to instructions, but you will be in a deeply relaxed, drowsy state throughout the procedure. Most patients have little or no memory of the treatment afterwards. It is not a general anaesthetic — you will not be fully asleep — but for many people it makes the experience feel almost effortless. IV sedation is particularly popular for longer procedures such as full-arch All-on-4 treatment, or for patients who have avoided dental care for years because of anxiety. If you would like to discuss sedation options at either our Leicester or Corby clinic, please mention this when you book your consultation.

What happens to my bone if I keep my dentures?

The jawbone requires stimulation from tooth roots to maintain its volume. When teeth are replaced with a denture (which sits on the gum, not in the bone), the underlying bone begins to resorb. Over years, this causes the jaw to shrink, the facial profile to collapse, and the denture to become increasingly ill-fitting. Only implants — anchored into the bone — can arrest this process.
