What does a dental filling cost in Germany — and why you only get a price after the examination

If you have statutory health insurance (gesetzliche Krankenversicherung, GKV) — as around 90 % of people in Germany do — a tooth-coloured filling as standard care costs you nothing. Not a reduced amount: nothing. Since dental amalgam was banned across the EU in 2025, the covered standard filling is a tooth-coloured material in every tooth, front and back. A bill appears only if you decide you want something above that standard: a more elaborate layering technique, or a laboratory-made inlay in ceramic or gold. Then you sign a written additional cost agreement (Mehrkostenvereinbarung) before treatment, the fund still pays what the standard filling would have cost, and you pay the difference. Private patients are billed under the fee schedule for dentists (GOZ), where the amount depends on the size and complexity of the work. This is why no honest practice quotes a filling price on the phone — until the decay is opened up, nobody knows how big the repair is.

For decades the deal in Germany was uncomfortable but clear. Amalgam — the grey metal filling — was standard care for back teeth and the fund paid for it in full. If you wanted a tooth-coloured filling in a molar, you paid the difference yourself.

That is history. Under EU rules, dental amalgam may no longer be used from 2025, apart from narrowly defined medical exceptions. Germany implemented the ban, and the statutory funds now cover a tooth-coloured filling as standard care in the back teeth as well — a composite that can be placed efficiently, durable, adhesive and free of charge to the patient.

For anyone who moved here before 2025 and remembers being asked to pay extra for a white filling at the back, this is the single most useful thing to know: that co-payment no longer exists for standard care. What still exists is a genuine choice above the standard, and that choice still costs money.

Two clarifications save a lot of confusion.

A filling is not a Festzuschuss case. The fixed subsidy (Festzuschuss), the bonus booklet (Bonusheft) and the treatment and cost plan (Heil- und Kostenplan, HKP) belong to dentures, crowns and bridges. For fillings there is no HKP, no percentage subsidy and no booklet stamps to collect. Fillings are simply covered — or, if you choose an upgrade, covered up to the standard value with a written agreement for the rest.

Anaesthetic is not an extra. Local anaesthetic (Betäubung) where medically indicated is part of the covered treatment. Sedation or laughing gas (Lachgas) for anxious patients is a separate private service, priced before the appointment rather than added afterwards.

This is the one piece of German paperwork worth understanding properly, because it is the only route by which a filling can end up costing you anything.

A Mehrkostenvereinbarung is a written document you sign before treatment. It records that you have chosen a more elaborate technique or material than the standard, states what you will pay, and confirms that the fund’s contribution towards the standard filling still applies. The legal basis sits in the German social code (SGB V).

Three practical rules follow:

1. It must be in writing and in advance. A verbal mention while you are already lying in the chair is not how this works. If you are asked to pay extra, ask for the agreement on paper and read it before signing. 2. You are never obliged to choose the upgrade. Declining an extra-cost option does not mean going untreated. It means the covered standard filling — tooth-coloured in every tooth since 2025. 3. You are entitled to know what you are buying. A good conversation covers what the more elaborate option does better in your mouth: how large the cavity is, how much chewing load the tooth carries, and how long each option would realistically be expected to last.

Whether you are a private patient, are weighing up an upgrade, or simply wonder why quoted figures vary so widely, the drivers are the same.

How many surfaces are involved. The biggest factor by far. A filling in one chewing surface is one job; a filling wrapping around two or three surfaces, including the wall between two teeth, is a different one — the tooth is rebuilt in three dimensions and the contact point with the neighbour has to be reconstructed so that floss passes with slight resistance and food does not pack in.

Where the tooth sits. A molar at the back is harder to reach, see and keep dry. In a front tooth, shade, translucency and texture have to match the neighbours.

How deep the decay has gone, and where the margin sits. A cavity that stops in the enamel is straightforward. One reaching the deep dentine, close to the pulp, needs protective steps and careful excavation, and sometimes a decision about whether the nerve can be preserved at all. Decay extending below the gum line adds bleeding, moisture and a margin that is difficult to seal.

Technique and material. A single-increment composite and a multi-layer adhesive build-up with individually shaded increments are not the same amount of work or time. Neither is an inlay, made in a laboratory from an impression or a digital scan and cemented at a second appointment.

How much tooth is left. At some point a filling stops being the sensible answer. If the walls are too thin to survive chewing, a partial crown or crown carries the load better — a bigger investment up front, and often the cheaper decision across ten years.

What we find when we open it. Decay spreads sideways along the junction between enamel and dentine, so it is routinely wider under the surface than it looks from above or on an X-ray. A one-surface plan becoming a two-surface reality is common; it is why estimates are given as ranges, and why any change is discussed with you before it is carried out.

You will find plenty of websites quoting a neat figure for a filling. We do not, and the reason is not coyness.

Before an examination we do not know how many surfaces are affected, how deep the decay runs, whether the nerve is involved, or whether the tooth still has enough substance for a filling to be the right answer at all. A number given without that information is a guess dressed up as transparency, and it tends to be revised upwards later.

What we offer instead is a sequence: examine, explain, put it in writing, then treat. The first consultation with us is free, so finding out what you are dealing with costs nothing. Where a 3D X-ray (DVT) is genuinely needed — not for a routine filling, but for a suspected fracture — it costs 178 €, and we say so beforehand. For extensive treatment, payment by instalments (Ratenzahlung, subject to a credit decision) can be arranged.

Private patients (private Krankenversicherung, PKV). You are billed directly by the practice under the official fee schedule for dentists (GOZ). Each item has a defined value, multiplied by a factor within a legally set range according to the difficulty of the individual case. You pay the practice and submit the invoice to your insurer, so how much comes back depends entirely on your tariff — worth checking the dental section of your policy before agreeing to elaborate work.

Supplementary dental insurance (Zahnzusatzversicherung). Top-up policies cover a share set by the tariff. Two caveats: most have waiting periods and limits in the first years, and none will cover treatment that was already recommended before you signed. If you have just arrived in Germany, it is worth knowing that fillings are one area where the statutory system is generous — the larger financial questions here arise with crowns, dentures and implants.

People comparing options usually compare the price today. The more useful comparison is what happens across a decade.

A composite filling in a moderate cavity is the least expensive route and, in the right situation, entirely adequate. In a very large cavity, the same filling works at the edge of what the material can do, and if it fails the replacement is bigger than the original — each cycle removes a little more tooth. An inlay handles heavy chewing loads well, at a higher cost and a second appointment; a crown protects the remaining tooth entirely, which is the right answer once the walls can no longer carry the load.

Our rule of thumb: the more of the original tooth that has already gone, the sooner it pays to stop repairing and start protecting. Which point you are at is a clinical judgement — Filling or crown? When each one makes sense goes through the decision in detail.

There is nothing awkward about asking “is this covered by my fund, or am I paying for it?” It is the single most useful sentence in German dentistry, and any practice worth attending will answer it plainly.

Your insurance card has not arrived yet. Bring the confirmation of membership from your insurer. Practices can usually treat you and settle the administration once the health insurance card (Gesundheitskarte, eGK) is issued.

Students and low income. Fillings as standard care are covered regardless of income. The hardship provision (Härtefallregelung) that many people have heard of applies to dentures, where a co-payment genuinely arises. For children and adolescents, the funds also cover preventive care designed to avoid fillings in the first place — ask which services apply at your child’s age.

Your German is limited. Cost conversations are where language barriers do the most damage, because this is where you agree to something. We discuss plans in English and give them to you in writing.
