Full profile →What does Invisalign treatment cost?
The cost of Invisalign treatment varies depending on the severity of the misalignment and the number of aligners needed. At our practice, costs usually range between 2,500 and 8,500 euros. How aligners compare in price to night guards, mandibular advancement devices, and retainers is shown in our overview What Does a Dental Appliance Cost?. Aligners are always a private service — statutory health insurance does not cover the costs for Invisalign. Private health insurance and supplemental dental insurance contribute depending on the policy.
| Scope of treatment | Cost (guide values)* | Typical duration |
|---|---|---|
| Minor tooth corrections | usually from approx. 2,500 euros | from approximately 6 months |
| Moderate corrections | usually approx. 4,000–6,000 euros | about 12 months |
| Complex treatments | usually approx. 6,000–8,500 euros, in rare cases more | up to about 18 months, longer with bite correction |
*All figures are non-binding reference values for orientation purposes. The actual price depends on your individual dental situation and is determined by the treatment and cost plan according to GOZ (the German fee schedule for dentists), which we prepare after the initial consultation.
What factors influence the cost of Invisalign?
The cost varies depending on the scope and duration of the treatment. The main influencing factors are:
- Type and severity of the misaligned teeth – minor corrections cost less than complex cases.
- Treatment duration – the more sets of aligners are needed, the higher the total cost.
- Number of check-up appointments – regular adjustments are part of a successful treatment.
- Additional services – e. g. retainers to stabilize the result (how long you wear them).
- Treatment planning and 3D scan — precise digital planning is the foundation for cost calculation and treatment outcome.
Digital precision for your individual treatment concept
At our practice, we use the most advanced digital technology — from the first 3D scan to the final treatment planning for tooth correction.

Two examples from our practice
Two cases from our practice show how differently aligner treatments can run depending on the finding. Both were treated with aligners from our in-house master dental laboratory; they show effort and duration, not the cost of an Invisalign treatment.
Crowding in an adult: A 36-year-old patient wanted a more even smile. Both dental arches were too narrow, the teeth were crowded and some were rotated; the bite itself did not need to be corrected. The treatment took 28 weeks. Read more in our treatment example: crowding corrected with aligners.
Several misalignments at once: An adult patient had an open bite, pronounced crowding in the lower jaw, a one-sided crossbite and an upper molar that could no longer be saved. With small anchorage implants in the palate and aligners, the gap, open bite, crowding and crossbite were corrected – without fixed braces and without a dental replacement for the gap. Read more in our treatment example: complex correction in adults – aligners with mini-anchorage.
Every finding is different: the course and outcome of an individual case cannot be transferred to other patients.
Benefits of Invisalign treatment
Aligners are clear and removable: You take the trays out for eating, brushing your teeth, and for drinks other than water. The trays are changed at regular intervals and move the teeth in small steps. When the condition is suitable, aligners are an alternative to fixed braces that interferes less with daily life.
Coverage by health insurance
Statutory health insurance (GKV)
Aligners are always a private service, regardless of age or diagnosis – statutory health insurance does not cover them, for adults as well as for children and adolescents. Whether you have statutory or private insurance: diagnostics, consultation, and care are the same for all patients in our practice.
Private health insurance (PKV)
For patients with private health insurance, coverage is often possible:
-
For children: often good chances if medical necessity is documented
-
For adults: Depends on your individual policy and its terms
-
We are happy to support you with the application by providing detailed documentation
-
For those entitled to allowances, we prepare the documentation for the subsidy office
Supplementary dental insurance
Depending on your plan, partial coverage of Invisalign therapy is possible, which can considerably reduce the treatment costs. Feel free to bring your insurance documents to the consultation.
Financing options
We know that costs play a significant role in the decision for treatment. That is why we offer flexible solutions at our practice:
- Installment payments on request, interest-free for up to 18 months.
- Individual financing models, which we discuss together during the consultation.
- Transparent cost plans, so that you keep an overview at all times.
Good to know: under certain circumstances, treatment costs can be claimed as extraordinary expenses on your tax return – your tax advisor can advise you individually on this.
How statutory health insurance, private insurance, reimbursement for civil servants, and interest-free installment payment work together is explained in our cost overview.
Our orthodontists and practice
Your Invisalign treatment is planned and supervised by a specialist in orthodontics. She reviews the treatment proposal in ClinCheck®, adjusts it where necessary, and approves it. In addition to Invisalign, we also treat with aligners fabricated in our in-house master dental laboratory; which approach suits your case will be discussed after the diagnostic evaluation. Instead of taking an impression, we use an intraoral scanner. During planning, you’ll see on the screen in advance where your teeth are intended to move. This is the goal of the planning, not a guaranteed outcome.
How she experienced her tooth correction with Invisalign is described by a patient of our practice in the video – a personal experience.

Treatment for children and adults
Invisalign is not only for adults. For adolescents and for children in mixed dentition, the system provides dedicated treatment pathways. Invisalign First is designed for children in mixed dentition, according to the manufacturer roughly between ages 6 and 10. The goal of such early treatment is to create space for the erupting permanent teeth, for example in cases of crowding, gaps, or narrow dental arches. What makes sense for your child will be determined during the examination; more on this under Invisalign for adolescents and children. We also treat adults with Invisalign when it fits the clinical findings.

Frequently asked questions about Invisalign costs
Are Invisalign treatments more expensive than fixed braces?
Not necessarily. At our practice, Invisalign treatment usually ranges between 2,500 and 8,500 euros, while fixed braces as a private service typically cost between 3,000 and 8,000 euros. Which is more cost-effective in your case depends on the clinical findings. If treatment begins before the 18th birthday and the case falls into KIG grades 3 to 5, statutory health insurance covers treatment with conventional removable or fixed braces. It pays 80 percent of the costs directly; the 20 percent patient share is reimbursed after successful completion of treatment. Aligners remain a private service even in those cases.
Can the costs be deducted from taxes?
Yes, under certain circumstances treatment costs can be claimed as extraordinary expenses in your tax return. Your tax advisor can advise you individually on this.
How long does an Invisalign treatment take on average?
Usually 6 to 18 months, longer with bite correction; minor corrections tend toward the lower end. How long it takes in your case depends on the clinical findings and on whether you wear the aligners 22 hours a day.
What happens if I lose or damage my aligners?
Call us. Until the appointment, you usually reinsert the previous aligner. Replacement Invisalign aligners are ordered from the manufacturer; depending on the situation, additional costs may apply.
Is there a non-binding cost estimate in advance?
Yes — after a thorough examination and digital planning, you will receive a detailed treatment and cost plan from us.
