The short answer
Fixed dental work (festsitzender Zahnersatz) — crowns, bridges and implant-supported restorations — is the right answer when there is something solid to attach it to and a healthy foundation to attach it in. That means enough sound tooth structure on the neighbouring teeth, or enough bone for an implant (Implantat), plus gums that are not actively inflamed. A single gap between two teeth that already need crowns is close to a textbook case for a bridge. A gap at the very back of the jaw with no tooth behind it cannot be bridged at all and needs either an implant or a removable solution. And a mouth with untreated gum disease is not ready for fixed work of any kind — that gets treated first, always, in whatever order the rest of the plan takes.
Start from the gap, not from the catalogue
Patients usually arrive having already decided. They read about implants, or a relative had a bridge, and the question they ask is “can I have one?”. The more useful question runs the other way: what does this gap allow? Three things decide almost everything.
How many teeth are missing, and are they next to each other? One gap is a different problem from four scattered gaps. A short span can be bridged; a long one puts a lot of leverage on the anchor teeth.
Where in the jaw? A gap between two teeth has abutments on both sides. A gap behind the last remaining tooth — a free-end gap (Freiendlücke) — has one abutment, and a bridge needs two.
What condition are the neighbours in? This is the point most people never consider, and it is often decisive.
One tooth missing, healthy neighbours
If the teeth on either side are intact — no large fillings, no crowns, no root canal treatment (Wurzelbehandlung) — then a conventional bridge means grinding down two healthy teeth to carry it. That is a real cost, paid in tooth substance rather than euros. In this constellation an implant is frequently the option that preserves the most, because it replaces the missing tooth without touching the neighbours. Long-term studies report implant survival of around 95 % and above, which is why this recommendation has become standard rather than adventurous.
One tooth missing, heavily restored neighbours
Now the arithmetic reverses. If both neighbours already carry large fillings or old crowns and need restoring anyway, a bridge does two jobs at once: it restores those teeth and fills the gap, with no surgery, no healing phase, and a treatment time measured in weeks rather than months. This is the classic, sensible bridge case — and it is worth saying clearly, because “implant” has become a default answer in a way the clinical picture does not always support.
The free-end gap: nothing to hang a bridge on
When the missing teeth are the last ones in the row, there is no second anchor. A bridge cannot cantilever a molar’s chewing load indefinitely off a single tooth in most situations. The realistic options are an implant to create the missing anchor, or a removable partial denture (Teilprothese) that clasps onto the remaining teeth. Which one is right depends on bone, budget, general health and how much a removable appliance would bother you.
Several teeth missing, scattered
The more gaps there are, the more the calculation shifts. Bridging every gap separately can mean crowning most of the remaining teeth. At some point a combination — a few implants carrying fixed work, or a removable solution anchored on precision attachments — protects more of what is left. For an edentulous jaw, fixed concepts such as All-on-4 exist, at a different order of planning and cost.
The four conditions fixed work needs
Whatever the design, the same foundations have to be in place. If one is missing, it gets fixed first — not skipped.
1. Gums that are not inflamed. Periodontitis (Parodontitis) is the condition most often overlooked before prosthetic treatment, and building fixed work on teeth with progressive attachment loss is building on a moving foundation. German dental associations are unambiguous that periodontal treatment precedes prosthetic reconstruction. In practice this adds a phase of a few months, and it is the phase that decides how long everything afterwards lasts.
2. Enough tooth substance, or enough bone. A crown needs a stump it can grip; a badly broken-down tooth may need a post and core first, and sometimes the honest verdict is that a tooth is not worth crowning. An implant needs bone in three dimensions. Where the bone has receded after a long-standing gap, a bone graft (Knochenaufbau) can rebuild it — a general market range in Germany is 500–2,500 €, which is background information rather than our price. A 3D X-ray (DVT) shows what a normal image cannot; ours costs 178 €.
3. A bite that makes sense. If the opposing tooth has drifted down into the gap over the years, or the neighbours have tilted, there may not be room for a restoration in the space that remains. Sometimes a tooth is straightened first with aligners, sometimes the opposing tooth is reshaped, occasionally it has to be accepted that the ideal is no longer available.
4. A patient who can clean it. Fixed work is cleaned differently from natural teeth, especially under a bridge. Where dexterity is limited — arthritis, neurological conditions — a design that can be taken out and cleaned in the hand may serve someone better than a fixed construction they cannot maintain. The technique is in Cleaning crowns and bridges properly.
Where each option tends to fit
| Situation | Usually the sensible route | Why |
|---|---|---|
| One gap, neighbours untouched | Implant with crown | Preserves healthy teeth; no grinding |
| One gap, neighbours need crowning anyway | Bridge | Two problems solved in one treatment, no surgery |
| Free-end gap at the back | Implant, or removable partial denture | A bridge needs two anchors |
| Large defect, tooth still restorable | Crown, partial crown or inlay | Keeps the natural root |
| Several scattered gaps | Combination, or removable design | Avoids crowning most of the mouth |
| Whole jaw, sufficient bone | Implant-supported fixed concepts | Fixed function without a palate plate |
| Active periodontitis anywhere | Periodontal treatment first | The foundation decides the outcome |
When fixed work is not the right plan — at least not yet
Being told “not now” is not a rejection. It is usually a sequence.
Active gum disease. Treated first. This is not a formality.
Insufficient bone, without a graft. An implant placed in inadequate bone is a poor investment. Grafting extends the timeline — the healing phase (Einheilphase) after implant placement is on average three to six months in any case — but it produces a foundation worth building on.
Untreated heavy grinding (Bruxismus). Ceramic tolerates a great deal, but not unlimited nightly force. Where there is clear evidence of grinding, a night guard (Knirscherschiene) belongs in the plan, and material choice is adapted accordingly.
Smoking. Smoking is associated with a higher rate of implant complications and poorer gum health generally. It does not automatically rule out treatment, but it changes the risk conversation and deserves an honest one.
Poorly controlled diabetes. Well-controlled diabetes is compatible with implants and fixed work in general; poorly controlled blood sugar impairs healing and raises infection risk, so stabilising it comes first — a conversation between you, your doctor and us.
Adolescents still growing. Implants are placed once jaw growth is complete, because an implant does not move with a growing jaw the way a natural tooth does.
Pregnancy. Planned prosthetic work is normally scheduled after the birth. Acute problems are always treated — untreated infection is the greater risk — and the second trimester is generally the most comfortable window.
Timing and budget. If a large plan is not affordable this year, staging it is a legitimate clinical decision, not a compromise. What matters is that the staging is deliberate: a long-term temporary while the rest is planned, rather than an abandoned half-finished mouth. The financial mechanics — fixed subsidy (Festzuschuss), bonus booklet (Bonusheft), treatment and cost plan (Heil- und Kostenplan, HKP) — are set out in What fixed dental work costs in Germany.
Does the decision have a deadline?
Not an urgent one, but not an open-ended one either, and it helps to know why.
A gap changes its surroundings slowly. The teeth beside it tend to tilt towards the space over the years, the opposing tooth tends to move into it, and the bone that once held the missing root gradually loses volume because nothing loads it any more. None of that happens overnight. What it does mean is that the range of good options is usually widest early: a gap restored within the first year rarely needs preparatory work, while a gap left for a decade may need bone rebuilt and neighbours straightened first. Where a visible front tooth is involved, gum contour is another thing that is easier to preserve than to recreate.
What to weigh up — and when to talk to us
If you have just moved to Germany
Two things regularly surprise new arrivals. The first is that a German dentist may recommend keeping and restoring a tooth that would have been extracted elsewhere — tooth preservation is the default position here, and treatment under a microscope makes it possible in cases that once looked hopeless. The second is that the recommendation comes with a written plan and no pressure to decide on the day.
Consenting to prosthetic treatment through a language you only half-follow is not consent in any meaningful sense. We treat patients in English, and if you are still finding your feet in the system, English-Speaking Dentist in NRW covers the practical groundwork. Patients travel to us from across NRW — Düsseldorf, Cologne, Bonn and the Ruhr cities — and 20 to 30 minutes for an appointment you can follow in English is a trade most expats make happily.

No. It is often the better choice when the neighbouring teeth are healthy, because it leaves them untouched. But when those neighbours already need crowns, a bridge restores them and closes the gap in one course of treatment, without surgery and without months of healing. The right answer depends on the teeth beside the gap, not on the technology.
Sometimes, and it is a legitimate discussion — particularly for the very last molar, where the functional loss can be limited. What has to be weighed is the tendency of neighbouring and opposing teeth to drift over the years. That is a decision to make deliberately with your dentist, not by default.
It means the bleeding is dealt with first. Bleeding gums indicate inflammation, and fixed work built on inflamed, receding support does not last as it should. Periodontal treatment usually takes a few months, after which the prosthetic plan is made on a stable foundation.
Usually yes, with adjustments: the material is chosen with the load in mind, the design avoids unnecessarily fragile shapes, and a night guard becomes part of the plan rather than an optional extra. What is not sensible is placing new ceramic into an unprotected grinding pattern and hoping.
A crown or bridge is typically a few weeks: preparation, laboratory work, fitting, with a temporary in between. An implant case is longer, because the healing phase averages three to six months before the final crown is made. Preparatory treatment such as gum therapy or a bone graft adds to the front of that timeline.
No, and you should not feel you do. The first consultation with us is free, you leave with the options explained and, where relevant, a written plan; taking it away to think, discuss at home or seek a second opinion is entirely normal in Germany.
Fixed dental work is not a status symbol and not a default — it is the right answer when the gap, the neighbouring teeth and the foundation allow it. Judge the neighbours before the technology: healthy teeth argue for an implant, teeth that need crowning anyway argue for a bridge, and a gap at the very end of the row rules a conventional bridge out. Where the gums are inflamed or the bone is thin, the sequence starts earlier than the prosthetics. Get that order right and the rest of the decision becomes much simpler than it looks.
