Why nobody can give you a price on the phone
It is the first question everybody asks and the one that cannot honestly be answered before somebody has looked in your mouth. The reason is not evasion. It is that the cost of aligner treatment is driven almost entirely by one variable that only an examination reveals: how many aligners your teeth need in order to get where they are going.
Every tray represents one small step. A case with a little crowding at the front of the lower jaw may need a modest series. A case where both arches are being reorganised, a rotation is being corrected and the bite relationship is being changed needs a much longer one, plus attachments, possibly elastics, and a review stage part-way through. Same method, same materials, very different amount of work.
Everything else in the quote follows from that number: the laboratory manufacture, the planning time, the number of appointments, and the length of the treatment.
What actually drives the price
Six factors, in roughly the order in which they matter.
1. One arch or both. Treating only the lower front teeth is a fundamentally smaller job than reorganising the upper and lower arches together. Many people arrive assuming both are always treated; often only one needs to be.
2. How far the teeth have to travel. Mild crowding, or a mild relapse after childhood braces, is at one end. A significantly rotated canine, a tipped molar or a bite that has to be changed sits at the other.
3. The number of aligners in the series. This is the direct expression of points 1 and 2 in manufacturing terms, and it is the number to ask about.
4. Attachments and IPR. Small composite bumps bonded to certain teeth so the tray has something to grip, and the very fine polishing between teeth used to create space. Both add chair time.
5. Refinements. Teeth do not always follow the plan exactly. A refinement means a fresh scan and an additional short series of trays to finish the job. This is a normal part of the method, not a failure — but whether it is included in the quoted price varies between providers, and it is the single most common cause of an unexpected bill.
6. Retention. When the last tray comes out, the result has to be held. A bonded wire behind the front teeth, a clear night-time retainer, or both. Retainers also wear out and get lost over the years, so this is a small ongoing item rather than a one-off.
What the three variants mean
Our three price points exist because those six factors cluster into three realistic case sizes.
| Variant | Typically covers | Who tends to fall here |
|---|---|---|
| 1,049 € | A limited correction — a small number of teeth, usually in one arch, over a short series of aligners | Mild crowding of the front teeth; a modest relapse years after childhood braces; a small gap |
| 2,800 € | A more comprehensive correction with a longer series, attachments where needed and a bite that requires attention | Moderate crowding, spacing across an arch, cases where both arches are involved |
| 3,699 € | The full scope: extensive movement across both arches, complex sequences, more planning and more appointments | Cases combining crowding, rotation and a bite relationship that has to be changed |
The table is orientation, not a quotation. Which band applies to you is set out in your written treatment and cost plan after an examination — and if your case sits near a boundary, you are entitled to have the reasoning explained in plain language before you agree to anything.
What the statutory health insurance actually pays
This is where most international patients lose their footing, because the German logic is unlike either the American or the British one. Here it is from the beginning.
KIG — the grading system that decides everything
German statutory funds do not decide orthodontic cover on the basis of how crooked teeth look. They decide it with a classification called KIG — Kieferorthopädische Indikationsgruppen, the orthodontic indication groups.
Every misalignment is assigned to one of five grades:
- KIG 1 — slight. A minor deviation with no functional consequence.
- KIG 2 — mild. Noticeable, but still classified as largely aesthetic.
- KIG 3 — moderate. A deviation with functional relevance.
- KIG 4 — severe. A pronounced deviation clearly affecting function.
- KIG 5 — extreme. Very severe deviations, including cases such as impacted teeth or congenitally missing teeth, and craniofacial conditions such as a cleft.
The grading is not a matter of opinion. It is based on measured findings — how far the upper front teeth protrude, how much space is missing in the arch, whether teeth are blocked out or absent, how the jaws relate to one another — recorded by the treating dentist or orthodontist from models, photographs and X-rays.
If your child is under 18 and graded KIG 3–5
Two further points that catch parents out.
What is covered is standard care (Regelversorgung) — which means fixed braces (feste Zahnspange), not aligners. Where a family chooses clear aligners instead, the fund’s contribution is directed at the standard treatment and the difference is a private extra. In other words: qualifying under KIG does not make aligner treatment free, it makes part of an alternative treatment subsidised.
The treatment plan goes to the fund before anything starts. As with all planned dental work in Germany, the paperwork precedes the treatment. Starting first and applying afterwards is the reliable way to lose an entitlement.
Where cover applies, families also advance 20 % of the fee during treatment — the Eigenanteil — which is reimbursed in full once the course has been completed in the scope the plan set out; a mechanism designed to encourage patients to see treatment through to the end. If treatment is broken off partway, the advance is not returned. Where two or more insured children who are under 18 at the start of treatment and live in the same household are being treated at the same time, the share for the second child and each further one is only 10 %.
If you are an adult
For adults, statutory cover for orthodontics exists only in narrow, severe circumstances — essentially where a pronounced jaw discrepancy requires combined orthodontic and surgical treatment. Ordinary adult orthodontics, including every aligner case undertaken for crowding, spacing or relapse, is a private service. Assume you are paying, and treat any contribution as a pleasant surprise.
Private and supplementary insurance
- Is adult orthodontics covered at all? Many policies cover it only for children, or not at all.
- Is there a waiting period? Most policies do not pay in the first months after they start.
- Was the treatment already recommended when you took the policy out? This is the decisive one. German supplementary insurance generally does not pay for treatment that was already diagnosed or advised before the policy began. Taking out a policy on the way home from the consultation is the classic mistake.
If you are still deciding whether such a policy is worth it in general, there is a separate article on that: Is supplementary dental insurance worth it?.
Paying for it in practice
Instalments. Instalment payment (Ratenzahlung) is possible with us, subject to a credit decision. For a treatment that runs over many months, spreading the cost across that period is what makes it feasible for most people.
Diagnostics. Where a case needs three-dimensional imaging, a DVT (3D X-ray) costs 178 € in our practice. Not every aligner case requires one — a digital scan and standard imaging are often sufficient. Whether imaging is included in a quoted package is a fair question to put to any provider, including us.
Tax. Medical expenses can, under certain conditions, be claimed in a German tax return as außergewöhnliche Belastungen (extraordinary burdens). Whether anything is actually deductible depends on your income and household circumstances, so this is a question for a tax adviser (Steuerberater) or an income tax assistance association (Lohnsteuerhilfeverein) rather than for a dental practice. Keep the invoices either way.
A word on the cheapest option. Mail-order aligner services that skip the in-person examination are the low end of this market. Whatever they cost, the thing you are not buying is the diagnosis — and as the article on Can clear aligners move every tooth? Possibilities and limits explains, the difference between a dental problem and a skeletal one cannot be established from photographs you take yourself.
Comparing quotes without getting lost
If you are gathering quotes across the region — and aligner patients do travel, to Wuppertal from Düsseldorf, Cologne and Bonn, and from much further across Germany — compare these eight items rather than the headline number. Ask for the answers in writing.
1. How many aligners are planned, and for which arch or arches? 2. Are attachments and IPR included? 3. Are refinements included, and if so, how many? 4. Is a retainer included at the end, and which kind? 5. Are diagnostics and imaging included, or billed separately? 6. How many check-up appointments are included? 7. What happens, and what does it cost, if you lose a tray? 8. What is the treatment plan if a movement does not work out as designed?
Two quotes that look several hundred euros apart often turn out to be identical once items 3 and 4 are settled.
What is normal in a quote — and when to ask again
If you have just moved to Germany
You cannot simply present your health insurance card and expect this to be handled. Adult orthodontics sits outside the statutory catalogue. Your Gesundheitskarte (eGK) is still needed for the examination and record-keeping, but the treatment itself is billed to you.
The written plan is your instrument. Ask for it, read it, and if any of it is unclear, ask for it to be explained in English. That is a normal request, not an imposition — English is one of our working languages, and there is more on navigating the German system in your own language here: English-Speaking Dentist in NRW.
Plan around your stay. Aligner treatment runs over months, and the retention that follows runs for years. If you are on a fixed-term contract, raise it at the consultation. It affects the sensible scope of treatment, and it is much better discussed at the start than in month nine. The timeline is covered in How long does clear aligner treatment take?.
Prices vary widely by provider and region, and there is no meaningful national figure. What we can tell you is our own: aligner treatment at our practice in Wuppertal is offered at 1,049 €, 2,800 € or 3,699 €, depending on the scope of the case. Which band applies is determined after an examination and appears in your written plan.
For an adult, almost certainly not. Statutory cover for orthodontics is limited to patients under 18 whose case is graded KIG 3 or higher, and even then it pays towards fixed braces as the standard treatment, with aligners remaining a private alternative. Adult cover exists only in rare severe cases involving jaw surgery.
It depends on the KIG grade. Below grade 3, the treatment is private at any age. From grade 3 upwards and under 18, statutory cover applies to standard fixed braces, with any upgrade — including aligners — payable privately. The plan goes to the fund before treatment starts, so ask for the grading and the plan in writing early.
Yes, instalment payment is possible with us subject to a credit decision. Because the treatment itself runs over many months, most patients find the payments align reasonably well with the course of treatment. Ask for the arrangement to be set out alongside the treatment plan.
Not necessarily — a lower price often reflects a smaller case, which is exactly as it should be. What matters is what the price includes. A quote without refinements and without a retainer is not cheaper than one with them; it is a different quote for a different thing.
Not with us — the first consultation is free. You can have your teeth examined, discuss whether aligners are the right tool for your case at all, and leave with an idea of the scope before you commit to anything.
Aligner pricing looks opaque from outside and is fairly logical from inside: the number of trays your teeth need is the cost, and everything else is detail. Our three variants — 1,049 €, 2,800 € and 3,699 € — reflect three realistic case sizes, and an examination is what places you in one of them.
On insurance, be realistic: as an adult in the statutory system you are paying for this yourself, and the KIG grading system is the reason. Where a policy might contribute, check the orthodontics clause and the start date before you count on it. And when you compare offers, compare refinements and retainers — that is where the real differences hide.
