Implant, Bridge or Denture? The Real Cost Over 20 Years

Quick answer: To compare the cost to replace a missing tooth, look beyond the first bill. Dentures cost least upfront but usually need replacing every five to eight years. Bridges sit in the middle and can last a decade or more. Implants cost most at the start but, with good care, can last many years, which can make them better value over time.

When you lose a tooth, the first quote you get tends to shape the decision. That’s understandable, but it can be misleading. A cheaper option that needs replacing three times can end up costing more than a pricier one that lasts.

This guide looks at the three main ways to replace a missing tooth in the UK, what each costs, how long each typically lasts, and how to work out which gives you the best value for your own circumstances. It isn’t clinical advice, and the right choice always depends on your mouth and your dentist’s assessment.

The Three Ways to Replace a Missing Tooth

Each option works differently, and that affects both price and lifespan.

Dental implants

To replace a missing tooth with an implant, a titanium post is placed into the jawbone, which acts as a root for a crown fitted on top. According to the Oral Health Foundation, implants are not normally available on the NHS and are provided privately.

Bridges

A bridge is a fixed way to replace a missing tooth, filling the gap with a false tooth attached to the teeth on either side for support. That reliance on neighbouring teeth is worth weighing up if they are healthy.

Dentures

A denture is a removable plate carrying one or more false teeth. Partial dentures replace a few teeth, while complete dentures replace a full arch. Most are made from acrylic, and some use a metal frame such as cobalt chromium.

What the NHS Covers When You Replace a Missing Tooth

If you’re eligible for NHS treatment, your costs look very different.

Bridges and dentures under Band 3

In England, bridges and dentures fall under Band 3 of NHS charges, which costs £332.10 per course of treatment from April 2026, according to the NHS Business Services Authority. Some people, including children and those on certain benefits, pay nothing.

Implants are the exception

Implants are generally only funded by the NHS where there is a specific medical need. Bupa Dental notes that most people need to pay for them privately. That is why the long-term cost comparison matters most for people choosing private treatment.

How Long Each Option Lasts

Lifespan is where the real cost to replace a missing tooth shows up.

Dentures: around five to eight years

Bupa states that dentures generally need replacing every five to eight years.

Bridges: often a decade or more

Colgate’s UK guidance suggests a fixed bridge can last between 10 and 25 years before it needs repair or replacement. How long yours lasts depends heavily on the health of the teeth supporting it.

Implants: many years with good care

The Oral Health Foundation says implants, much like natural teeth, will last as long as you care for them, and that well looked-after implants on healthy bone can be expected to last for many years. Bupa reports that studies show over 90% of implants last more than 10 years.

Real Private Prices: A Worked Example

Published fee guides make it possible to compare like with like. As an example, at Cliftonville Dental, where I work as a Northampton dentist, we list our full fees online. These are our current starting prices:

Option	Published starting price
Single implant, including final crown	£3,190
Bridge	from £695 per unit
Acrylic denture	from £619
Cobalt chromium denture	from £1,197

These are one practice’s figures, and the final cost depends on your case. A bridge, for instance, is priced per unit and can involve more than one unit, so always ask for the total.

Running the numbers over 20 years

Here is a simple illustration using the starting prices above and the lifespans quoted earlier. It ignores check-ups, repairs and any extra treatment, so treat it as a rough guide rather than a prediction.

Acrylic denture: replaced roughly every five to eight years means around three dentures over 20 years, or about £1,857 at today’s starting price.
Bridge: if it lasts 10 to 25 years, you might need one replacement within 20 years, doubling the original bill.
Implant: one implant and crown at £3,190, with the possibility of the crown needing replacement at some point.

The gap between options narrows over time. For some people, a denture remains the most affordable choice. For others, an implant’s longer life makes the higher upfront price easier to justify. The Oral Health Foundation goes as far as saying that over the longer term, implants are usually a more cost-effective option, though that depends on your circumstances.

Costs That Don’t Show on the Price List

When you replace a missing tooth, the headline fee isn’t the whole story.

Assessment and scans

Implant treatment usually starts with an assessment and imaging. At our practice, a CT scan is listed from £139 and a new patient consultation at £135, so factor these in.

Maintenance

All three options need good home care and regular check-ups. How long implants and bridges last depends on healthy gums and, for bridges, healthy supporting teeth.

Effects on other teeth

A bridge relies on neighbouring teeth, which may need work later. That potential future cost is worth discussing with your dentist before you choose.

How to Decide the Best Way to Replace a Missing Tooth

Cost is only one factor, so weigh it against what matters most to you.

Questions to ask your dentist

Which options are clinically suitable for me?
What will the total cost be, including scans and follow-up visits?
How long can I realistically expect each option to last in my mouth?
What happens if it fails, and is there any guarantee?

Spreading the cost

Many private practices offer finance to spread larger costs if you need to replace a missing tooth privately. It can make treatment more manageable, but it is still borrowing, so check the total repayable and only borrow what you can comfortably afford.

The Bottom Line

The cheapest way to replace a missing tooth today isn’t always the cheapest over the next 20 years. Ask for written quotes, compare lifespans honestly and think about the total cost over the time you expect to keep the tooth, not just the first payment.

Frequently Asked Questions

What is the cheapest way to replace a missing tooth?

Upfront, a denture is usually the least expensive option. On the NHS in England, bridges and dentures both fall under the Band 3 charge of £332.10 from April 2026.

Are dental implants worth the money?

They can be, especially if you want a long-lasting fixed option. Studies reported by Bupa show over 90% of implants last more than 10 years, but suitability depends on your bone and gum health.

How long does a dental bridge last?

Colgate’s UK guidance suggests 10 to 25 years, depending largely on the health of the supporting teeth and how well they are cared for.

Can I get an implant on the NHS?

Usually not. Implants are generally only NHS-funded where there is a specific medical need, so most people pay privately.
