What does a root canal cost in Germany? Why the price depends on the tooth, not the practice

Most dental work can at least be described in ranges. Root canal treatment resists it more than almost anything else in the practice, and it is worth understanding why before you compare quotes.

The treatment is not a product. It is time spent inside a space a fraction of a millimetre wide, that nobody can see from the outside and that varies from person to person more than almost any other anatomy in the body. Two teeth in the same position in two mouths can differ by an hour of work and by two appointments. The X-ray narrows the estimate down; some of it is only known once the tooth is open.

This is also why we do not publish a figure for it here. We can and do give every patient a written estimate for their own tooth after examining it — which is a different thing from a number on a website that would be wrong for most of the people reading it.

1. Which tooth it is. This is the single biggest driver. Lower incisors usually have one canal. Premolars have one or two. Upper molars commonly have three or four, and the fourth is often the awkward one to find. Since the canal work is recorded per canal, the tooth position essentially sets the baseline before anything else is considered.

2. What state the nerve and the root tip are in. A tooth with an inflamed but living pulp is a different job from a tooth whose nerve has died and which has developed an area of infection at the root tip. The second usually needs more disinfection, more working time and sometimes an extra appointment with a dressing in between.

3. What the anatomy turns out to be. Curved canals, canals narrowed by decades of calcification, an unusual extra canal, a canal that splits: all of these add working time. So does a tooth that has been treated before, or one carrying a post that has to come out first.

4. Which techniques are used. Magnification, machine-driven nickel-titanium preparation, electronic measurement of the canal length, extended disinfection protocols and 3D imaging are not part of the statutory catalogue. Each is offered separately, each has a price, and each is a decision you make in advance rather than discover on an invoice.

5. How many appointments it takes. One visit or three changes the total, and the answer depends on the first four points rather than on preference.

Here is the part that reliably surprises patients, including ones who researched carefully. A back tooth that has had root canal treatment has lost substance from the inside as well as the outside, and generally needs a crown (Krone) to stop it splitting under chewing loads. That crown is frequently the largest line in the whole project.

It also runs on a different system. Crowns belong to dentures (Zahnersatz), which means a treatment and cost plan (Heil- und Kostenplan, HKP) goes to your fund before the work starts — submitted late, the entitlement can be lost — and processing times vary from fund to fund.

Your fund then pays a fixed subsidy (Festzuschuss), not a percentage of your invoice. It is a set amount tied to the finding in your mouth, and you pay the difference between that amount and the cost of whatever you choose. How large it is depends on your bonus booklet (Bonusheft). For a single tooth needing a crown, the concrete amounts for 2026 are:

Two practical consequences. First, a check-up you skipped four years ago is costing you money today — the gap between the top and bottom rows is well over a hundred euros on one tooth. Second, ask about the crown at the same appointment as the canal work. The commonest financial shock in endodontics is not the treatment; it is the second plan that arrives afterwards.

A draft law that passed cabinet on 29 April 2026 proposes lowering those percentages to 50/60/65 %, with the 100 % hardship rate kept. It has not passed the Bundestag or the Bundesrat, so treat it as a proposal under discussion rather than something to plan around; the coverage rules as they stand are set out in Does German health insurance pay for a root canal? (EN).

Private dental services in Germany are not priced freely. They are billed under the fee schedule for dentists (Gebührenordnung für Zahnärzte, GOZ): every service carries a fixed number of points, one point is worth 5.62421 cents — a figure that has not changed since 1988 — and the result is multiplied by a factor between 1.0 and 3.5. The factor 2.3 represents a service of average difficulty and effort. Above 2.3 the dentist has to justify the higher rate in writing on the invoice, with reference to the difficulty of your particular case; above 3.5 nothing may be charged at all unless a written fee agreement (Honorarvereinbarung) was signed before the treatment started.

That single mechanism explains something patients often misread as overcharging. Two entirely honest invoices for what looks like “the same treatment” can differ, because one tooth genuinely took longer and was harder to work in. It also gives you a reasonable question to ask: which factor is applied here, and why? Asking it is normal, and a practice should be able to answer it in a sentence.

If you are holding quotes from two practices, do not start with the totals. Compare them line by line, in this order.

1. Same tooth, same number of canals? If one estimate assumes three canals and the other four, they are not describing the same job. 2. Is the rebuild included, or only the canal work? A quote that stops at the root filling is not a quote for a finished tooth. 3. Is the crown in there, or is it a separate plan? Usually separate — check whether the HKP has been prepared and what your share on it is. 4. Which extras are included, and are they optional? Microscope, 3D X-ray, extended disinfection. You are entitled to know which items you could decline and what declining them would mean. 5. How many appointments does each assume? A cheaper plan with more visits may cost you more in time off work. 6. What happens if the tooth turns out not to be saveable once opened? A good estimate names the fallback. Sometimes that can only be judged after the first appointment — which is honest, and should still be said out loud.

The estimate that looks dearer at the bottom is quite often the one that includes something the other quietly left out.

Say so early. It changes the conversation productively rather than ending it, and there are more routes than people assume.

• Instalments (Ratenzahlung) are available with us, subject to a credit decision. It is a normal request and asking for it does not affect your treatment.
• The hardship provision raises the subsidy for the crown to up to 100 % of the standard option if your income is below the defined threshold. Your fund decides this, and it is worth applying rather than assuming you do not qualify.
• Staged treatment. Settling the infection first and placing a durable temporary restoration, with the definitive work planned for later, is a legitimate clinical route rather than a compromise.
• Supplementary dental insurance (Zahnzusatzversicherung) typically reimburses a share set by the tariff of private costs depending on the tariff — but almost all policies exclude treatment for something already diagnosed or advised before the policy began, so this is a plan for your next tooth rather than this one.
