If you've lost a tooth, or you're about to, you've probably already come across the dental implant vs bridge question. Both options fill the gap and both can look natural. But they work in quite different ways, and that difference matters more than most people realise. At Hocking Dental Care we talk through both options with every patient who's missing a tooth, so you understand what each one involves before you decide.
This guide walks through how a dental implant and a dental bridge actually work, what happens to the teeth next door, how each one is cleaned day to day, and what tends to drive the cost up or down. There's no one right answer for everybody. The right choice depends on your own mouth, your budget and what matters most to you.
What is a dental implant?
A dental implant replaces the whole tooth, not just the part you can see. A small titanium post is placed into the jawbone where the root used to be. Once it has settled in, a crown is fitted on top to replace the visible tooth.
Because the post sits in the bone and holds its own crown, a dental implant stands on its own. It doesn't lean on the teeth either side of the gap for support. You can read more about how we assess and place implants on our dental implants page.
What is a dental bridge?
A dental bridge fills the gap in a different way. Instead of placing something in the bone, a bridge uses the two teeth next to the gap as anchors. Those teeth are shaped down to hold crowns, and a false tooth is fixed between them, a bit like a small bridge across a river.
A bridge doesn't involve surgery, and because it sits on existing teeth rather than in the bone, it's generally a quicker process overall. Our bridges page has more detail on when a bridge might suit your situation.
Dental implant vs bridge: the effect on neighbouring teeth
This is often the biggest point of difference, and it's worth thinking about carefully.
A bridge needs support from the teeth on either side of the gap. To hold the crowns that anchor the bridge, those teeth need to be shaped down. If they're already healthy and untouched, that's a permanent change to two teeth that didn't need any work before. If those teeth already have large fillings or crowns, there's less to lose, and a bridge can make more sense.
An implant doesn't ask anything of the neighbouring teeth. The post goes into the bone where the missing tooth's root used to be, so the teeth either side are left alone.
What happens to the jawbone?
When a tooth is missing, the bone underneath the gap gradually loses some of its shape over time, because it's no longer getting the stimulation a tooth root once provided through everyday chewing.
An implant post sits in the bone in a similar position to a natural root, so it continues to give that area some stimulation. A bridge sits above the gum line and doesn't reach down into the bone, so it doesn't offer the same effect. This is one reason some people prefer an implant for a gap that's likely to be left unfilled for a long time.
Cleaning an implant compared with a bridge
Cleaning around an implant
Once an implant crown is in place, you can generally brush and floss it much like a natural tooth. There's no gap underneath to thread anything through, because the crown sits directly over the implant post.
Cleaning under a bridge
A bridge has a false tooth suspended between two crowns, which leaves a small space underneath that a normal toothbrush can't reach properly. You'll need to floss under the bridge with a floss threader or a similar tool to keep that area clean. Keeping up with this is important, because the crowned teeth holding the bridge still need to stay healthy and free of decay.
What affects the cost of each option
We're often asked which option costs less, and the honest answer is that it depends on your situation. Rather than list figures that go out of date quickly, it helps to understand what actually drives the cost for each one.
For an implant, cost is affected by things like whether you need any preparation before the post can be placed, how straightforward the placement is, and the type of crown that goes on top. For a bridge, cost depends mainly on how many crowns are needed to anchor it and the materials used.
Before any treatment starts, our team gives you a written estimate with item numbers, so you know exactly what's involved and can check it against your health fund. If you're with HBF, Medibank, HCF, nib or Bupa, we're a preferred provider, which usually means a smaller gap for you to pay, though it's not free and the amount varies by policy. Other funds can still claim through HICAPS on the day.
Which one is right for you?
There isn't a single answer that suits everyone, but a few things tend to guide the decision. If the teeth next to your gap are already healthy and you'd rather not touch them, that points towards an implant. If those same teeth already have large fillings or crowns, or you're after a quicker result without surgery, a bridge can be a sensible option.
Your own health, the amount of bone in the area, and how soon you need the gap filled all play a part too. This is exactly why we look at your mouth in person, often with the help of our intraoral camera, so you can see the same picture we see on the screen beside the chair before we talk through what suits you.
Frequently asked questions
Is a dental implant better than a bridge for one missing tooth?
Neither option is automatically better for everyone. An implant leaves neighbouring teeth untouched and can help maintain bone in the area, while a bridge avoids surgery and is often finished sooner. The right choice depends on the health of the teeth next to the gap and your own circumstances.
How long does each option take to complete?
A bridge is usually finished over a shorter number of visits, since it doesn't involve surgery. An implant takes longer overall because the post needs time to settle into the bone before the crown is fitted. We'll give you a timeframe specific to your situation once we've had a look.
Does a missing tooth need to be replaced straight away?
Not always, but leaving a gap for a long time can allow neighbouring teeth to shift and bone to change shape underneath. If you've recently had a tooth removed, it's worth asking us how your healing is progressing before deciding on the next step.
What if I'm not sure which option suits me?
That's completely normal, and it's exactly what a check-up is for. We'll look at the gap, the surrounding teeth and your bone, talk through both options honestly, and answer your questions before you decide anything.
Can I still get health fund benefits for an implant or bridge?
Many extras policies include some cover for implants and bridges, but the rules and limits vary a lot between funds. Check with your own provider, and remember that most extras limits reset on 31 December, though it's worth confirming your fund's exact reset date.
If you're weighing up a dental implant vs bridge for your own missing tooth, the best next step is a proper look in the chair.
