Comparing the three
Implant, bridge or denture?
An implant replaces the root as well as the tooth and leaves the neighbouring teeth alone, but it needs enough bone and several months. A bridge is fixed and quicker, and the teeth either side have to be prepared to carry it. A denture is removable, replaces several teeth at once and changes nothing about your own teeth. Which is right depends on your mouth, not on a ranking.
Three different ways of solving the same problem
A missing tooth is one problem with three quite different solutions, and they are not three price points on the same thing. Each one borrows support from somewhere, and where it borrows from is the real difference between them.
An implant borrows from the bone. A fixture goes into the jaw, the bone grows around it, and a crown goes on top once it has healed. Nothing else in your mouth is involved.
A bridge borrows from the teeth either side. They are prepared, and a false tooth is joined to crowns that sit over them. It is fixed in place and it is finished in weeks rather than months, and the cost is that two teeth have been changed permanently to replace one.
A denture borrows from the gum, and from your remaining teeth if it is a partial. It comes out at night, it can replace many teeth at once, and it changes nothing about the teeth you still have.
How do they compare?
| Implant | Bridge | Denture | |
|---|---|---|---|
| What holds it in | Its own root in the jawbone | The teeth either side of the gap | The gum, and clasps on your own teeth for a partial |
| Does it touch the neighbouring teeth | No | Yes. They are prepared to carry it | A partial rests or clips on them |
| Fixed or removable | Fixed | Fixed | Removable, and taken out at night |
| How long before it is finished | Months, because the bone has to heal around it | Weeks | Weeks, and longer if extractions have to settle first |
| Bone where the tooth was | Loaded, so it behaves more like a tooth root | Not loaded. The ridge under the gap still shrinks | Not loaded, and the fit changes as the ridge changes |
| Replacing several teeth at once | Possible, and priced accordingly | Limited by how many teeth can carry it | Straightforward, including a whole arch |
| Cleaning | Brush and clean around it like a tooth | Needs cleaning underneath, which takes a technique | Out, brushed, and the mouth cleaned separately |
| What it needs later | Check-ups, and the crown on top can need attention | Depends on the teeth carrying it staying healthy | Relining or replacing as the gums change |
What usually decides it?
In practice the choice narrows quickly once someone has actually looked, and it narrows on four things.
- Bone. An implant needs enough of it, and the x-rays settle that before anything else is discussed. Where there is not enough, grafting is sometimes possible and sometimes not.
- The teeth either side. If they already carry large fillings or crowns, using them for a bridge costs you little. If they are untouched, it costs you a great deal.
- How many teeth are missing. One gap is an implant or bridge conversation. Several spread around the mouth is usually a partial denture conversation.
- Gum health and smoking. Both change what will last. Severe gum disease has to be treated before anything is placed, whichever option you choose.
Time and money matter too, and nobody should pretend otherwise. They belong in the conversation openly rather than quietly steering it, which is why no fees appear on this page. The implant cost page and the cost guide set those out where you can compare them properly.
The one thing all three have in common
Every one of them needs looking after, and every one of them will need something done to it eventually. An implant crown can chip or loosen. A bridge depends entirely on the teeth holding it staying healthy, and cleaning underneath it is a technique rather than an instinct. A denture needs relining as the gums change with age, which the Better Health Channel describes as normal rather than a fault.
That is worth knowing before you choose, because "permanent" is used loosely in dentistry. What you are choosing is which kind of maintenance suits your life, not whether there will be any.
How is this decided at Y3 Smiles Dental?
With an assessment and imaging, and with all three options on the table rather than the one the clinic prefers. Implant treatment at Y3 Smiles Dental is provided by our dentists, denture work is done by a registered dental prosthetist, and bridge work sits with the general dental team, so there is no commercial reason here to steer you towards one of the three.
Principal dentist Dr Fatima Kurnaz, a general dentist rather than a registered specialist, reviews the clinical information on this page. Cases that belong with a specialist are referred on.
Other questions people ask
Which one is best?
There is no answer to that question in the abstract, and a clinic that gives you one without looking in your mouth is selling rather than advising. What decides it is how much bone is there, how healthy the teeth either side are, how many teeth are missing, your general health, and what you can commit to in time and money. The same gap in two different mouths can have two different right answers.
Can anyone have an implant?
No. The Australian Dental Association is direct about this: there has to be enough bone to hold the implant, and people with severe gum disease or who smoke are often not suitable. That is what the x-rays and the assessment are for, and finding out early saves you paying for imaging on a plan that was never going to work.
Why does an implant take so long?
Because the bone has to grow around it before it can be used, which takes around three months. Nothing is happening during that time that you can feel or speed up. A temporary is usually arranged so you are not left with a visible gap.
What is the catch with a bridge?
The teeth either side have to be prepared to carry it, and that part cannot be undone. If those teeth already have large fillings or crowns, that is a reasonable use of them. If they are untouched, you are spending two healthy teeth to replace one missing one, which is worth saying out loud before you agree to it.
Are dentures the cheap option?
They cost less, and that is not the same as being a lesser choice. A well made denture replaces several teeth at once, changes nothing about your remaining teeth, and can be added to if you lose another. For some people it is simply the right treatment rather than the affordable one.
Do I have to replace the tooth at all?
Not always. One back tooth missing, with a stable bite and good cleaning, is something plenty of people live with. What is worth knowing is that the teeth either side can tip into the space and the ridge of bone shrinks once the tooth has gone, so choosing not to replace it is a decision to make deliberately rather than by drifting.
Can I start with one and change later?
Often yes, and it is a sensible way to handle a decision you are not ready to make. A denture now does not stop an implant later, provided the bone is looked after. Going the other way is harder, because a prepared tooth stays prepared.
