A zirconia bridge or an implant?

The long-term price of cutting down the neighbouring teeth, and of the bone under a bridge

This question is often taken to be about materials. It is not. Zirconia is a ceramic used both in bridges and in fixed teeth on implants; the difference lies in what the teeth rest on. On this page we explain what a bridge takes from the neighbouring teeth and from the bone beneath it, the situations in which a bridge is still the right decision, and where the limit lies when many teeth are missing. Send us your X-ray and we will write and tell you which route is on the table for you within one working day.

Short answer

Zirconia is a material and an implant is a support, so the comparison is made on the support, not the material. A bridge files down the teeth on either side of the gap on every surface and sits on top of them; it puts no load at all on the bone in the gap, and that bone goes on shrinking. An implant passes the chewing load straight into the jawbone, leaves the neighbouring teeth untouched and keeps the bone in place with that load. If the neighbouring teeth need crowns anyway, a bridge is still a sound decision.

Zirconia is the name of a material; the real question is what the tooth rests on

Zirconia is a white, hard ceramic with no metal support inside it. Because it lets light through in a way close to a natural tooth, it is preferred at the front of the mouth, and because it is strong, it is used at the back as well. But zirconia is not a support; it is a material for crowns. The same zirconia can be found both in a bridge that holds on to the neighbouring teeth and in fixed teeth that sit on implants. So the question "zirconia or implant" compares two different categories. The right question is this: what will these teeth rest on, your neighbouring teeth or your own jawbone?

This is how a bridge works. The teeth on either side of the gap are prepared (filed down) on every surface to a set thickness so that crowns can fit over them. These two teeth are called supporting teeth. The false tooth that takes the place of the missing one is made in a single piece joined to these two crowns. There is no root under the false tooth; it sits on the gum and passes the load it carries to the supporting teeth on either side.

The first price here is the tissue that is filed away. Enamel is a tissue the body cannot regenerate; once it is cut away, it does not come back. The thickness needed for a crown thins the layer surrounding the living core of the tooth; that is why sensitivity to hot and cold is normal in the first weeks, and why some supporting teeth need root canal treatment over the years. The second price is the edge that the crown leaves at the gum line: decay starts here and, because it progresses under the crown, it is noticed late. The third is dependence. A bridge is a single piece; if one of the supporting teeth is lost, the whole bridge goes and you are left with a three-tooth gap instead of a one-tooth gap.

The second issue is what goes on under the bridge. The jawbone stays in place as long as it carries load; the area where a tooth was taken out carries no load, so the bone there starts to reduce. A bridge does not change this, because the false tooth passes the load not to the bone beneath it but to the supporting teeth on either side. The shrinkage carries on quietly underneath. A few years later a space opens up between the false tooth and the gum: food gets trapped, cleaning becomes harder and, at the front of the mouth, the space becomes visible when you smile. A bridge closes the gap; it does not preserve the bone.

This is exactly where an implant is different. It sits inside the bone and passes the chewing load straight to the bone. Because the bone carries load, it stays in that area. The neighbouring teeth are left untouched; a sound tooth stays sound, and if it needs treatment of its own later, the rest of a bridge does not depend on it. Even if an implant is lost, the loss is confined to that area and does not drag the neighbouring teeth down with it.

The method we use takes this logic to the whole jaw. Instead of looking for volume in the soft spongy bone inside, a strategic implant locks mechanically into the hard outer layer of the jaw, the cortical bone. What provides the anchorage is not months of waiting for fusion but this locking, which is there from the first day. That is why we go ahead without bone graft material, and the fixed teeth are fitted over three clinic days. The teeth fitted on top can still be zirconia; what changes is not the material but what that material rests on.

Which situations point to an implant, and which to a bridge

The distinction below becomes clear after an examination and a CBCT scan. The second list does not say that a bridge is a bad option; it describes the situations in which a bridge still makes sense.

The tooth can be saved

The teeth on either side of the gap are soundFiling down two teeth that have nothing wrong with them for the sake of a bridge means bringing teeth that need no treatment into the treatment. An implant does not touch those teeth at all; the gap is dealt with on its own.
A gap at the back with nothing behind itIf there is no tooth left behind the missing one to rest on, a conventional bridge cannot be built; a bridge needs two supports. In this situation the options are an implant or a removable denture.
Many teeth are missingA bridge rests on its own supports. As the number of missing teeth rises, the load on the supporting teeth grows, the span gets longer, and the bridge both wears out sooner and uses up its supporting teeth faster. This is exactly where this protocol belongs.
Preserving the bone is your priorityThe bone in the gap reduces as long as it carries no load, and over the years this also affects the support of the lower part of the face. The only solution that passes load to the bone is an implant.

Saving it is unlikely to hold

The neighbouring teeth need crowns anywayIf the supporting teeth are going to be crowned in any case, because they have large fillings, are fractured or have had root canal treatment, the main price of a bridge all but disappears. In this situation a bridge is a sensible decision.
A one-tooth gapFor a single gap, a bridge or a conventional single-tooth implant is more appropriate. Our approach is built around restoring the whole jaw with one plan; for a single gap it is more extensive than needed.
A state of health that rules out surgeryA systemic illness that is not under control, a bleeding disorder or certain medicines that affect bone metabolism change the plan. Because a bridge needs no surgery, it comes to the fore in this situation.
Jaws in which the cortical layer is damaged tooA large cyst, previous jaw surgery or severe trauma also damages the hard outer layer. If no sound surface is left to anchor in, a bridge or a denture is what needs to be discussed; the CBCT scan shows this.

How we make the decision

This sequence is for the decision, not for the treatment. At the end of it you know what is possible in your mouth and what that is based on.

1
Send us your scan
If you have a panoramic X-ray or a CBCT scan, send it through the form. The scan is read by the dentist who will carry out the treatment; the first reply is written by the dentist, not an assistant. You do not need to come in; we get back to you within one working day.
2
A map of the gaps
How many gaps there are, where they are, whether there is a tooth left behind them to rest on and how the opposite jaw bites. This map shows whether a bridge can be built; a one-tooth gap and a back area with nothing behind it are not the same question.
3
The real condition of the supporting teeth
If a bridge is being discussed, the real question is this: what state are the teeth that would be filed down in today? How deep their fillings are, their history of root canal treatment, any decay and their bone support change the decision directly. Sacrificing two sound teeth and using two teeth that are going to be crowned anyway are not the same calculation.
4
A three-dimensional CBCT scan
A panoramic X-ray is two-dimensional; it gives an idea of the height of the bone but not of its thickness or the condition of the hard outer layer. The decision with this method rests directly on where the cortical layer is, how thick it is and how sound it is; we make no promises before we have seen a CBCT scan.
5
General health and medicines
We want to see your systemic illnesses, the medicines you take regularly and your latest test results. Diabetes is not a barrier; we use this protocol for people with diabetes. It affects the planning and the order of the steps.
6
You get the plan in writing
How many implants, in which jaw, with what bridgework and which teeth will be kept are set out in writing. If in your situation the right answer is a bridge, we write that just as plainly. Once we have agreed on the plan, the surgery and the fitting of the fixed teeth are spread over three clinic days.

Ways to close a gap

There are five routes, and none of them is superior to the others in every case. Which is right for you is decided by where the gap is, how many gaps there are and the condition of the neighbouring teeth.

Zirconia bridge

It holds on to the teeth on either side, it is quick and it needs no surgery. The price is that two teeth are filed down irreversibly and the bone beneath it is left without load. If the supporting teeth are going to be crowned anyway, this price largely disappears.

Resin-bonded bridge

A type of bridge whose wings are bonded to the back surfaces of the neighbouring teeth, with almost no filing down. Its use is narrow: it is chosen at the front of the mouth, for a one-tooth gap and when the neighbouring teeth are sound. It holds less firmly than a conventional bridge.

Single-tooth implant

The solution for a single gap that leaves the neighbouring teeth untouched. A conventional implant anchors in the spongy inner tissue of the bone, and fusion has to be waited for. A single missing tooth is not our field; in that situation, referring you to another clinic is part of our job too.

Fixed teeth on strategic implants

The implants lock into the hard outer layer, and fixed teeth made in one piece sit on top of them. A graft and months of waiting do not come into it; the fixed teeth are fitted over three clinic days. For mouths with many missing teeth and a sound cortical layer.

Removable denture

Still a valid option for patients who do not want surgery or whose health does not allow it. But since there is no tooth root beneath it, the bone carries no load; it goes on shrinking and the denture loosens over time.

What you should know when you decide

We write these not to frighten you but so that you can ask the right questions at whichever clinic you go to.

A bridge cannot be undone

Enamel that has been filed away does not come back. Even if you have the bridge removed years later and move to implants, those two teeth now depend on crowns. This is the permanent side of the decision; where sound teeth are concerned, you need to know it from the start.

A bridge lasts as long as its weakest support

Because it is a single piece, decay, a fracture or gum loss in one of the supporting teeth brings the whole bridge into question. Each time it is replaced, a little more tissue is taken from the supporting teeth; this cycle gets shorter with every replacement.

Decay progresses under the crown

The edge of the crown at the gum line is where decay starts, and decay that starts there cannot be seen by eye. That is why it matters that patients with a bridge do not miss their regular check-ups.

Cleaning under a bridge is a job of its own

Under the false tooth cannot be cleaned with ordinary floss; you need an interdental brush or special floss that threads under the bridge. When this is neglected, the gum becomes inflamed first, and then the bone support of the supporting teeth reduces.

Implants need care too

The gum around an implant can become inflamed too, and if that inflammation progresses, the bone around it is lost. Having fixed teeth does not mean you are exempt from regular cleaning and check-ups. Smoking, uncontrolled diabetes and neglected oral hygiene are known to increase the risk.

An implant can be lost

As with every implant method, there is a chance of failure with this one too, and we say so from the start. We set out in writing in the treatment plan what will be done if this happens; we do not leave it as a verbal promise.

What to expect afterwards

The course below applies to fixed teeth on implants. With a bridge there is no surgery; what to expect there is that sensitivity to hot and cold in the filed-down teeth settles in the first weeks.

Three clinic days
Once the examination and planning are complete, the surgery and the fitting of the fixed teeth are spread over these days. You do not leave the clinic without teeth. Some swelling and tenderness over these days is normal.
The first week
The swelling goes down. We ask you to eat soft food, to stay away from hard and hot food and to brush the area gently. If there are stitches, they are removed during this period.
The first weeks
We increase the chewing load step by step. Habits such as hard-shelled foods and chewing ice are put off during this period. Over these weeks the gum settles into its new shape.
Check-ups and the long term
We give you the check-up schedule and the care routine for the bridgework in writing. Interdental cleaning, regular professional cleaning and yearly imaging are the very things that make this treatment last.

Message us right away if

Swelling increases after the third day. Swelling goes down as healing progresses. If it is increasing, we need to assess it.
You have a fever. A fever is a warning sign of infection. Call us without waiting.
Numbness does not wear off. Tell us about any numbness that persists in your lip, chin or tongue.

What sets the cost

We give no figures on this page, because the right figure can only be given once the scans have been read. Send us your scan and we will set out the scope in writing, item by item. These are the items that set the total:

How many gaps, which jaw: One jaw or both, how many implants are planned and in which areas they will be placed set the total directly.
How many teeth are filed down for a bridge: The scope of a bridge is measured not by the number of false teeth but by how many supporting teeth will be crowned. If those teeth first need root canal treatment or decay removed, these are added to the bill as well.
Preparing the mouth: If there are teeth that have to be taken out, gum inflammation that has to be treated or roots that have to be removed, these are added to the plan and affect the timetable too.
Bridgework: The material of the fixed teeth and the laboratory work affect the total directly. We tell you the brand of the material we use in writing from the start.
The replacement timetable: The real cost of a solution does not end with the first bill. When a bridge is replaced, more tissue is taken from the supporting teeth; with an implant, the bridgework is replaced and the implant itself stays in place. We recommend working out the total over ten years.

Frequently asked questions

Which looks better, a zirconia bridge or an implant?

Both can be zirconia, so the difference in appearance does not come from the material. The difference shows over time: the bone under the false tooth of a bridge carries no load, so it shrinks, and a few years later a dark space opens up between the false tooth and the gum. At the front of the mouth this space shows when you smile. Because an implant passes load to that area, the gum line stays in place for longer.

My neighbouring teeth are completely sound. Do they still have to be cut down?

For a conventional bridge, yes. For a crown to fit, the tooth is filed down on every surface to a set thickness, and that enamel does not come back. Where two sound teeth are concerned, this means bringing teeth that need no treatment into the treatment. If there is a single gap and the neighbouring teeth are sound, a resin-bonded bridge or a single-tooth implant solves it without paying this price.

Is there a way to stop the bone under a bridge from shrinking?

What keeps bone in place is load, and the false tooth of a bridge puts no load on the bone beneath it; it passes the load to the supporting teeth on either side. That is why a bridge does not stop the shrinkage. The only solution that passes load to that area is an implant.

A space has opened under my bridge and food gets trapped. What should I do?

This is the typical sign that the bone beneath has shrunk back, and it does not put itself right. If trapped food stays there, the gums around the supporting teeth become inflamed and there is a risk of losing the teeth that carry the bridge too. Send us your X-ray; we will look at the bone support of the supporting teeth and write and tell you whether the bridge needs replacing or the plan needs to change.

How many teeth can a bridge replace?

What decides it is not the number of missing teeth but how much load the supporting teeth can carry. The longer the span, the more the bridge flexes and the greater the force on the supporting teeth; when the bone support of those teeth cannot withstand that force, both the bridge and the supporting teeth are lost. If there is no tooth left behind the missing one to rest on, a conventional bridge cannot be built anyway. When many teeth are missing, the question is not how many teeth a bridge will span but how the mouth as a whole will be restored.

I have a bridge. If I move to implants, what happens to those teeth?

The decision depends on the present condition of the supporting teeth. Supporting teeth with good bone support that are standing firm can be kept; the plan is built around them. Supporting teeth that have lost their bone support, have fractured or have decayed underneath are taken out, and that area is brought into the implant plan. The CBCT scan shows which applies in your case.

I have diabetes and was told I cannot have implants. Is a bridge my only option?

No. Diabetes is not a barrier, and we use this protocol for people with diabetes. What decides it is that your blood sugar is being monitored and that there is no active inflammation in your mouth. If your blood sugar is poorly controlled, we get it under control first; skipping that step does nobody any favours.

Why don't you put prices on the page?

Because two patients who come with the same question end up with very different plans: one has a single gap and two sound neighbouring teeth, while for the other, preparing the mouth is a separate job in itself. Any figure we wrote would either alarm you unnecessarily or change at the clinic.
