Dental Implants Leicester & Corby  |  Natural Smiles Implant & Cosmetic Dentistry

If you’re researching dental implants in Leicester or Corby, it’s only natural to wonder: what if something goes wrong? It’s a fair question — and one we believe you deserve a completely honest answer to.

At Natural Smiles, we’ve been placing dental implants for over 20 years across both our Leicester and Corby practices. We’ve seen what works, what doesn’t, and exactly how to give you the best possible chance of long-term success. This guide covers everything you need to know — without the sales gloss.

The Honest Answer First: Do Dental Implants Ever Fail?

Yes — but rarely. And more importantly, most failures are preventable.

That 2–5% failure figure might sound alarming at first. But here’s what it really means: the overwhelming majority of patients who choose dental implants — whether a single tooth replacement, All-on-4 full arch implants, or implant-retained dentures — go on to enjoy a natural-looking, fully functional smile for many years, often decades.

What Does ‘Implant Failure’ Actually Mean?

An implant ‘fails’ when it does not properly integrate with the surrounding jawbone, or loses its stability over time. Clinically, this is known as a failure of osseointegration — the process by which the titanium implant fuses with your bone to create a stable, permanent foundation for your replacement tooth.

Failure can happen at two distinct stages:

Early Failure (within weeks or a few months of placement) — the implant fails to bond with the bone during the healing phase. This is typically associated with infection, inadequate bone volume, or patient health factors.

Late Failure (months or years after successful integration) — the implant becomes unstable due to bone loss, infection (peri-implantitis), or excessive mechanical stress. Late failure is more often linked to oral hygiene habits and ongoing maintenance.

Understanding this distinction matters — because the causes, warning signs and treatment approaches differ depending on when the problem occurs.

The Most Common Causes of Dental Implant Failure

These are the areas where careful planning, skilled placement and thorough aftercare make all the difference — and where your Natural Smiles team focuses its efforts on your behalf.

1. Smoking — The Single Biggest Risk Factor

Smoking is consistently identified in clinical research as the primary cause of dental implant failure. Nicotine and carbon monoxide significantly reduce blood flow to the gums and jawbone, which directly compromises your body’s ability to heal after implant placement.

Specifically, smoking:

• Slows and disrupts the osseointegration process
• Dramatically increases the risk of post-surgical infection
• Impairs gum tissue healing around the implant
• Increases susceptibility to peri-implantitis (implant gum disease)

2. Insufficient Bone Volume or Poor Bone Quality

Your dental implants rely entirely on healthy, dense jawbone to provide the grip and stability needed for long-term success. If your bone is too thin, too soft, or has receded significantly — often as a result of missing teeth, gum disease, or years of wearing dentures — the implant may fail to integrate, or may loosen over time.

This is one of the most common reasons patients are told elsewhere that they ‘are not suitable’ for implants. At Natural Smiles, we use advanced 3D CBCT scanning to precisely assess your bone before treatment. Where bone grafting is needed, we carry this out as part of a carefully planned treatment process.

3. Peri-Implantitis (Infection Around the Implant)

Peri-implantitis is essentially gum disease affecting the tissue and bone around a dental implant. It causes progressive bone loss that, if left untreated, will ultimately cause the implant to fail. It is one of the leading causes of late implant failure globally.

Key causes of peri-implantitis include:

• Poor daily oral hygiene — bacteria build-up around the implant crown
• Infrequent or skipped professional hygiene appointments
• Residual cement left around the implant crown at the time of fitting
• A compromised immune system or poorly controlled diabetes

The good news: peri-implantitis is highly preventable and, if caught early, very manageable. This is exactly why our structured hygiene and review programme at Natural Smiles is a core part of your implant care — not an optional extra.

4. Poor Implant Positioning or Planning

Dental implants are not simply ‘screws in bone’. They are precision-engineered restorations that must be placed at exactly the right angle, depth and position relative to your neighbouring teeth, your bite, and the available bone structure.

Poor positioning leads to:

• Excess mechanical load on the implant (overloading)
• Bite imbalance — putting abnormal stress on one area of your jaw
• Aesthetic problems with your final crown or bridge
• Increased risk of long-term bone loss and loosening

5. Uncontrolled Medical Conditions

Certain systemic health conditions can significantly affect your body’s ability to heal and integrate an implant successfully. These include:

• Uncontrolled Type 2 Diabetes — poor healing and elevated infection risk
• Osteoporosis and bisphosphonate medication — can interfere with bone healing and remodelling
• Autoimmune conditions — may affect your immune response around the implant
• Blood clotting disorders — increase surgical risk and healing time

This is why your full medical history is an essential part of your consultation at Natural Smiles. We don’t just assess your teeth — we assess you as a whole patient.

6. Excessive Bite Force or Bruxism (Teeth Grinding)

Bruxism — habitual grinding or clenching of the teeth, often during sleep — places enormous and repetitive force on implants. Over time, this can cause micro-fractures in the bone around your implant, loosening, or even fracture of the implant components themselves.

If you are a known grinder, this does not automatically rule out implants — but it does mean additional precautions are essential. At Natural Smiles, we carefully design your bite and may recommend a custom-made night guard to protect your implant investment.

Warning Signs of a Failing Dental Implant

Whether your implants were placed at Natural Smiles or elsewhere, knowing the early warning signs means you can act quickly. Early intervention significantly improves outcomes and can often save an implant that would otherwise be lost.

Contact us promptly if you notice any of the following:

• Pain, discomfort or sensitivity when biting or chewing
• Any movement or looseness of the implant or crown
• Swelling, redness or bleeding around the implant site
• A persistent bad taste or unpleasant odour near the implant
• Visible gum recession revealing the implant post below the gumline
• A dull aching pain in the jaw or around the implant area

What Happens If a Dental Implant Does Fail?

This is one of the questions patients worry about most — and understandably so. Here’s the honest picture of what the process typically looks like:

1. Assessment and diagnosis — we carry out X-rays and CBCT scanning to understand exactly what has happened and why.
2. Removal of the implant — if the implant is not stable, it is removed under local anaesthetic. This is usually straightforward and much simpler than the original placement.
3. Treatment of any infection or bone loss — if peri-implantitis or infection is present, this is treated thoroughly before any further work is considered.
4. Healing period — the site is allowed to fully recover. This typically takes 3–6 months depending on the extent of bone loss.
5. Bone grafting (if required) — if bone volume has been lost, a bone graft may be needed to rebuild a suitable foundation for the replacement implant.
6. Replacement implant — once conditions are ideal, a new implant can be placed. In many cases, this is successful long-term.

How Natural Smiles Minimises Your Risk of Implant Failure

This is where our approach at Natural Smiles truly sets us apart from many dental practices across Leicestershire and Northamptonshire. We are not a high-volume implant ‘production line’. We are a specialist team that invests the time to get every stage right — for you.

Advanced 3D Digital Planning (CBCT Scanning)

We use Cone Beam CT (CBCT) 3D scanning as standard for all implant patients. Unlike conventional dental X-rays, CBCT scanning shows us:

• Exact bone width, height and density at your implant site
• The precise location of nerves, sinuses and anatomical structures
• The ideal implant position, angle and length
• Any bone deficiencies that need addressing before treatment begins

Using this data, we create a detailed digital treatment plan and, where appropriate, 3D-printed surgical guides — templates that ensure your implant is placed exactly where planned. This removes the guesswork from surgery entirely.

20+ Years of Implant Experience

Implant dentistry is one of the most technique-sensitive areas of modern dentistry. The difference between an experienced implant dentist and one who has recently completed a short course is substantial.

With over 20 years of implant experience at Natural Smiles, you benefit from:

• The ability to anticipate and manage complications before they arise
• A thorough understanding of which implant systems work best for different clinical situations
• Experience with complex cases — including bone grafting, sinus lifts and All-on-4 full arch restorations
• Calm, measured clinical decision-making at every stage of your treatment

Thorough Patient Assessment — Every Time

We don’t accept patients for implant treatment without a thorough, personalised assessment. Yours will include:

• Full medical history review and medication assessment
• Bone quality and volume evaluation using your CBCT scan
• Gum health evaluation — treating any gum disease before implant placement
• Bite analysis and detailed occlusal (bite) planning
• Lifestyle factor review — including smoking, alcohol, diet and stress

Strict Surgical Protocols

In the surgical environment at Natural Smiles, every implant placement follows meticulous protocols designed to minimise your risk:

• Full aseptic (sterile) technique throughout your procedure
• Digital surgical guides for precise, repeatable implant placement
• Careful soft tissue handling to preserve your gum health
• Appropriate implant torque measurement for optimal primary stability
• Clear post-operative instructions and accessible aftercare support from day one

Long-Term Maintenance & Hygiene Support

Your implant is a long-term investment. At Natural Smiles, we provide structured aftercare because we know that ongoing maintenance is what separates a 5-year implant from a 20-year one.

Our implant aftercare programme includes:

• Regular implant health review appointments
• Professional hygiene appointments using implant-specific instruments
• Bite monitoring and assessment at each visit
• Early detection of peri-implantitis before it becomes a serious problem

All-on-4 Dental Implants in Leicester & Corby — Are the Risks Different?

All-on-4 is a full-arch implant solution — replacing all of the teeth in your upper or lower jaw (or both) using just four strategically placed implants. It is a life-changing treatment for patients who have lost many or all of their teeth and want a fixed, permanent result.

The failure risks for All-on-4 are broadly similar to single implants, but there are some important additional considerations for you to be aware of:

• All four implants must integrate successfully — if one fails, it can affect the stability of the whole arch restoration
• The initial ‘immediate loading’ phase — when your temporary teeth are fitted on the same day — requires very careful bite management and dietary guidance
• Bone quality and volume are even more critical for All-on-4, which is why CBCT planning is absolutely non-negotiable in our practice
• Long-term hygiene beneath the full arch bridge requires specific cleaning techniques — which we teach all our All-on-4 patients at Natural Smiles

At Natural Smiles Leicester and Natural Smiles Corby, All-on-4 is carried out by our most experienced implant clinician, with full 3D digital planning and dedicated long-term follow-up support. It is one of the most transformative treatments we have the privilege of providing.

Our 5-Year Dental Implant Warranty — Peace of Mind as Standard

At Natural Smiles, we stand behind the quality of our implant work. That’s why we offer every eligible patient a 5-year warranty on their dental implants — giving you genuine confidence in your investment from day one.

We are able to offer this warranty because of the standard of care we deliver at every stage — from your initial CBCT scan and digital treatment planning, through to precision placement and structured aftercare. This is not a warranty offered lightly. It is a reflection of the confidence we have in our clinical process.

How the Warranty Works

Your 5-year implant warranty is straightforward. To remain valid, you simply need to attend your regular maintenance appointments at Natural Smiles. This is not a bureaucratic condition — it is genuinely in your best interest.

Regular maintenance appointments allow us to monitor your implants closely, detect any early signs of peri-implantitis, and ensure your bite, gums and bone remain in excellent health. Patients who attend regularly enjoy far better long-term outcomes — and the warranty is our way of formally recognising and rewarding that commitment.

What the Warranty Covers

• The structural integrity of the implant itself
• Failure of osseointegration (implant not bonding with bone) within the warranty period
• Clinical complications directly related to the implant placement itself

Why We Offer This Warranty

Not every dental practice offering implants provides a warranty. We do — because we are confident in our clinical standards, our experience, and the quality of the implant systems we use. A warranty is only worth offering when you are certain of the quality behind it.

When you are comparing implant providers in Leicestershire or Northamptonshire, we encourage you to ask every practice a simple question: do you offer a warranty on your implants? The answer will tell you a great deal about the confidence they have in their own work.

Are Dental Implants Still Worth It?

Absolutely — when planned and placed correctly, dental implants remain the gold standard solution for missing teeth. Despite the small failure risk, here is why they remain the right choice for the vast majority of patients:

• They look, feel and function like your natural teeth
• They preserve your jawbone — preventing the bone loss that inevitably occurs with missing teeth
• They do not rely on or damage neighbouring teeth, unlike conventional bridges
• They restore your confidence, your comfort, and your ability to eat what you enjoy
• When well-maintained, they can last for many decades — often a lifetime

The key is choosing the right clinic and the right clinician — one who will invest the time to plan your treatment properly, place your implants with precision, and support you with genuine long-term aftercare.
