The upfront cost of a dental implant is higher than a bridge or partial denture — but implants typically last significantly longer before needing replacement. Over a 15–20 year horizon, the picture often reverses. Use the calculator below to compare the real long-term cost for your specific situation.

Why Long-Term Cost Matters
A dental bridge costs £1,200–£1,800 per tooth gap at a UK private clinic and typically lasts 10–15 years before needing replacement. A partial denture costs £600–£1,200 and requires relining or replacement every 5–8 years. An implant costs £1,800–£3,500 upfront but the titanium fixture rarely needs replacing — only the crown (approximately every 12–15 years at around £600–£800).
The calculation is most compelling for younger patients — a 40-year-old choosing between options is making a 30–40 year decision. Over that horizon, the implant’s higher upfront cost is amortised across many fewer replacements than a bridge or denture.
What the Calculator Assumes
The calculator uses UK average mid-range prices and evidence-based replacement schedules. It includes an annual maintenance cost (hygiene appointments and check-ups) for each option. The bridge replacement schedule assumes a 10–11 year lifespan — some bridges last longer, some shorter. The denture schedule assumes relining at year 5–6 and replacement at year 10–12.
The calculator does not account for: the cost of repairing the adjacent teeth to support a bridge (which may be an additional cost if those teeth are healthy), or the bone loss that occurs under a bridge or denture site over time (which can complicate future treatment).
The Hidden Cost: Adjacent Tooth Damage
One factor the calculator cannot easily quantify is the long-term risk to the teeth adjacent to a bridge. Preparing a bridge requires reducing the two neighbouring teeth to crowns — even if those teeth are healthy. Over time, these prepared teeth are more prone to decay, nerve damage and eventual loss. This is why most implantologists recommend implants over bridges when bone and general health permit: the adjacent teeth are left completely untouched.
Frequently Asked Questions
Is a dental implant cheaper than a bridge long term?
For most patients, yes — typically from around years 12–15 onwards. The implant’s higher upfront cost is offset by fewer replacements over a 20–25 year horizon. A bridge requires replacement every 10–12 years, while the implant fixture rarely needs replacing and the crown lasts 12–15 years. Use the calculator above to see the specific crossover point for your situation.
How long does a dental bridge last compared to an implant?
A well-maintained dental bridge typically lasts 10–15 years before needing replacement. A dental implant fixture can last 20–30+ years; the crown (the visible part) typically lasts 12–15 years before replacement. This means an implant may need one crown replacement over the same period that a bridge needs one or two full replacements.
Is a dental implant better than a bridge?
For most patients with adequate bone and good general health, implants are the preferred option for several reasons: the adjacent teeth are not damaged, the implant preserves jawbone at the extraction site, and the long-term cost is usually lower. However, bridges may be more appropriate when adjacent teeth already need crowning, when bone volume is insufficient for an implant, or when the patient cannot undergo implant surgery for medical reasons.
