How Long Do Dental
Implants Last?

What the published evidence shows

Across the dental implantology literature, single-tooth dental implants have:

- 5-year survival: 95–98% - 10-year survival: 92–96% - 20-year survival: 80–90% - 30-year survival: approximately 70%

These figures are for implants placed in healthy adults at non-augmented sites by qualified clinicians. They are remarkably consistent across the major published series since the 1990s.

Implants placed in compromised sites (heavy bone augmentation, smokers, uncontrolled diabetes) have lower survival figures, typically 5–15 percentage points lower at the same time-point.

This makes implants the most predictable long-term tooth-replacement option in dentistry. By comparison, conventional bridges have 10-year survival around 75–85%, and removable partial dentures are typically replaced or refurbished every 5–8 years.

Tower Dental implant outcomes

Across 2024–25 dental implant cases delivered at Tower Dental Blackpool by Dr San Chatterjee (GDC 84643, MID Royal College of Surgeons Edinburgh):

These figures are reviewed annually as part of our clinical-governance audit. Long-term (10-year+) outcome data for implants placed at Tower Dental will become available as the cohort matures.

Comprehensive practice-specific data is published on our [implant-outcomes-data](implant-outcomes-data.html) page.

What affects how long an implant lasts

Five factors determine implant longevity:

1. Oral hygiene and recall attendance. This is the dominant factor. Peri-implantitis (inflammation of the gum and bone around the implant) is the leading cause of late implant failure and is preventable with twice-yearly hygienist appointments and good home care. Tower Dental data shows plan-member patients (who attend recall reliably) have substantially lower late-failure rates. 2. Smoking. Smokers have 1.5–2× higher implant failure rates across the literature. Stopping smoking before placement substantially improves long-term outcomes. 3. Bone quality and quantity at placement. Implants placed in dense, well-vascularised bone have better long-term survival than those in compromised or grafted sites. 4. Crown design and bite. A well-designed crown with appropriate occlusal contacts protects the implant from overload. Heavy parafunction (grinding) without a night guard shortens crown life and can stress the implant. 5. Surgical technique and clinician experience. This includes implant brand, placement angle, primary stability achieved, and aftercare protocol. Dr Chatterjee uses Straumann and Nobel Biocare implants — both are major brands with extensive long-term clinical data.

How to make your implant last 25+ years

Five practical things patients can do:

1. Attend twice-yearly hygienist appointments. This is the single most important factor. The Tower Dental adult plan (£19.60/month) includes two routine examinations and two hygienist appointments per year. 2. Use the right home-care tools. Inter-dental brushes (TePe or similar) sized to your implant restoration, plus a manual or rotary toothbrush, twice daily. 3. Stop smoking if you currently smoke. 4. Wear a night guard if you grind your teeth. Cost £200–£350 — substantially cheaper than replacing a fractured crown. 5. Attend annual implant-specific reviews with periapical radiographs at the 12-month, 5-year and 10-year marks to monitor crestal bone levels.

Crown vs implant — what fails first

Patients sometimes confuse the lifespan of the *crown* with the lifespan of the *implant body*. They are different.

The implant body (titanium) is integrated into bone and, in healthy maintained patients, often outlasts the patient. Titanium does not biodegrade.

The crown (porcelain or zirconia) attached to the implant is a wearing component — it experiences chewing forces and can chip, fracture, or wear over decades. Crowns are typically replaced at 10–15 years, sometimes earlier if heavy bite forces are present.

When a crown fails, the implant body is usually still healthy. Replacement is straightforward and far cheaper than replacing the implant itself: typically £580–£950 at Tower Dental for a screw-retained replacement crown on an existing implant.
