If you’ve lost a tooth — or you’re about to — you’ve probably been handed three words and told to pick: implant, bridge, or denture. None of them is automatically the right answer. The honest version depends on your mouth, your health, your budget, and how long you want this to last.

Here’s how I talk patients through it in the chair at Biltoft, and what the real ten-year picture looks like for each option.

What each option actually is

Dental implant

A titanium screw placed into the jawbone to act as an artificial tooth root. Once it integrates with the bone (usually three to six months), we build a crown on top. It looks and functions like a normal tooth — you floss it, chew on it, and forget it’s there.

Best for: replacing a single tooth without touching the neighbours, or anchoring multiple teeth when several are missing.

Bridge

A run of connected crowns that “bridges” a gap. The two teeth either side of the missing tooth get prepared (reduced in size), and a three-unit bridge is cemented over them — two crowns as anchors with a fake tooth suspended in the middle.

Best for: gaps where the neighbouring teeth already have big fillings or crowns and would benefit from being covered anyway. Less ideal when the neighbours are virgin teeth.

Denture

A removable appliance that replaces some teeth (partial) or all teeth in an arch (full). Modern dentures are typically acrylic or acrylic with a lightweight cobalt-chrome frame, as Healthdirect notes. Partial dentures clip onto remaining teeth; full dentures rest on the gums.

Best for: multiple missing teeth, patients who aren’t candidates for surgery, or situations where budget rules out fixed options.

How long each one actually lasts

Longevity is where the marketing copy and real life often part ways. In our practice, the rough picture looks like this:

  • Implants: the implant itself can last decades with good care. The crown on top may need replacing at some point — 15 years is a fair expectation, sometimes longer.
  • Bridges: typically 10–15 years before the bridge needs replacing. The failure point is usually decay starting under one of the anchor crowns, or an anchor tooth itself giving up.
  • Dentures: partial dentures often need relining every few years and remaking every 5–8 years as the jaw shape changes. Full dentures follow a similar cycle.

None of these are forever. Individual results vary, and things like grinding, gum disease, and general oral hygiene push the numbers around in both directions.

The bone question — and why it matters

This is the point that usually surprises people. When you lose a tooth, the bone that used to hold the root starts to shrink. It’s called alveolar resorption, and it’s well-documented in the dental literature — systematic reviews consistently show meaningful ridge width and height loss in the months after extraction (Couso-Queiruga et al., 2021).

A bridge sits above the gum. A denture sits on top of the gum. Neither stimulates the bone the way a natural tooth root does. Only implants load the bone directly, which is why they’re currently the only replacement option that helps preserve the ridge over time.

Does that make a bridge or denture “wrong”? No. Plenty of patients wear them happily for decades. But if you’re 35 and weighing up options for a front tooth, the long-term bone picture is a real factor worth knowing about.

What they cost — at Biltoft

Being straight with you about pricing:

  • Single dental implant (full package — surgery, abutment and crown): $5,000–$6,000 per tooth at our Murwillumbah practice.
  • Bridges and dentures: these vary too much by case for me to give a blanket price. A three-unit bridge is different to a four-unit bridge. A single-tooth partial denture is different to a full upper. The materials, the condition of the supporting teeth, and the number of teeth involved all change the number. We quote these properly after an exam.

If you’re comparing implant pricing around Australia more broadly, our sister piece on dental implant cost in Australia for 2026 walks through what’s normal and what’s a red flag.

One more thing on cost: we don’t offer IV sedation or general anaesthetic in-house. Everything at Biltoft is done under local anaesthetic. For patients who genuinely need sedation we refer to a specialist oral surgeon. That keeps our overheads honest and our prices where they are.

If you’re weighing up which option fits your situation, the simplest next step is booking a consult so we can look at the actual tooth, the neighbours, and the bone underneath — guesswork doesn’t help anyone at this stage.

The ten-year cost picture (honestly)

Upfront price isn’t the whole story. Here’s how it tends to play out over a decade:

Implant: one upfront cost of $5,000–$6,000. Ten years later, most implants are still doing their job. Maintenance is a normal clean and check-up twice a year.

Bridge: a lower upfront cost, but at the 10–15 year mark there’s a reasonable chance you’re replacing it — and replacement often means the anchor teeth need more work, or have developed decay underneath. If a supporting tooth fails, the whole bridge comes out and you’re making a bigger decision about what comes next.

Denture: the lowest upfront cost in most cases, but the highest ongoing one. Relines, adjustments as the jaw shrinks, and a full remake every 5–8 years are normal. Ten years in, most patients have had at least one significant rework.

When people say “implants are cheaper in the long run,” that’s the maths they’re pointing at. Whether it’s true for your case depends on how long you need the tooth to last and whether you’d prefer to pay once or in instalments over decades.

Effect on the teeth you still have

This is the factor that often tips the decision for me clinically.

  • Implant: no impact on the neighbouring teeth. Stands alone.
  • Bridge: requires grinding down the two teeth either side, even if they’re completely healthy. That’s tooth structure you can’t get back.
  • Partial denture: clasps onto existing teeth, which over time can put extra load on them and can be a spot where plaque builds up. With good hygiene it’s manageable; without it, the anchor teeth can suffer.

If the teeth either side of your gap are already heavily filled, a bridge is actually a reasonable plan — those teeth probably need crowning anyway, so you’re getting two jobs done for the price of slightly more. If they’re untouched, I’d push harder for an implant.

So which one is actually right?

Honestly? It depends. A front tooth in a healthy 30-year-old is almost always an implant conversation. A back tooth in someone with bone loss and a tight budget might be better served by a partial denture. A gap flanked by two heavily-filled teeth in a 60-year-old can be a perfect bridge case.

The worst answer is the one picked because someone found a number online. The best answer is the one made after looking at your X-rays, your bone, your bite, and your priorities.

Frequently asked questions

Which lasts longer — an implant, a bridge or a denture? +

Generally implants have the longest track record, often lasting decades when cared for well. Bridges typically last 10–15 years before needing replacement. Conventional dentures usually need relines or remakes every 5–8 years as the jaw changes shape. Individual results vary.

Is an implant always the best choice? +

No. Implants need enough bone, good general health, and a bigger upfront budget. For some patients a well-made bridge or a partial denture is genuinely the right answer — either because of health factors, cost, or the position of the gap. We'll tell you honestly what suits your case.

Why do bridges involve grinding the neighbouring teeth? +

A traditional bridge uses the teeth on either side of the gap as anchors. To fit crowns over them we have to remove a layer of tooth structure. If those neighbours are already heavily filled or cracked, that can actually be a good thing. If they're healthy and untouched, it's a real downside to weigh up.

Do dentures cause bone loss? +

Dentures sit on top of the gum — they don't stimulate the jawbone the way a tooth root does. Over time the ridge under a denture tends to shrink, which is why dentures need relines and eventually remakes. Implants are currently the only replacement that loads the bone directly and helps preserve it.

What do these options cost at Biltoft Dental? +

A single dental implant (surgery, abutment and crown) at our practice is $5,000–$6,000 per tooth. Bridges and dentures vary too much by case to quote blanket pricing — the number of teeth, materials and condition of the neighbouring teeth all change the cost. We quote these properly after an exam and X-rays.

I've been told I don't have enough bone for an implant. What now? +

Bone grafting can sometimes rebuild the ridge enough to place an implant later. If grafting isn't sensible for your case, a bridge or partial denture is a perfectly good Plan B. We refer to a specialist oral surgeon when grafting is the right call.
