There is no age limit to start orthodontic treatment. Straightening crooked teeth, closing gaps between teeth, aligning teeth, and adjusting bite and chewing function. Aesthetic treatments, including invisible and traditional orthodontics, have been available for years to help you regain your smile.
Orthodontics without extraction. Thanks to its expertise in advanced technologies, Dr. Arnould’s practice offers orthodontic treatments that avoid tooth extraction. Depending on the case, it is possible to create enough space to align teeth without resorting to maxillofacial surgery or tooth extraction. We recommend early screening for your child, ideally between 6 and 9 years old, to act before it’s too late. Dr. Arnould also provides orthodontic treatments for adults.

🦷 Treatment with Invisible Transparent Aligners: Clear Aligners / Orthodontics for Adults:
Advantages of Transparent Aligners:
- Discreet and nearly invisible
- Removable for convenience
- Comfortable to wear
- Aesthetically pleasing, especially for adults
- Faster and less painful treatment
- Suitable for all ages
Advantages of Transparent Aligners:
Invisible orthodontic treatments with transparent aligners have been clinically proven since 1997. These custom-made orthodontic aligners are crafted using computer programs and manual finishing to ensure each aligner fits your teeth perfectly. Each aligner gently moves your teeth—horizontally, vertically, and even with rotation if needed. The aligners are designed to apply the right amount of force at the right place and time. As you switch to the next set of aligners (typically every 2 weeks), your teeth gradually shift according to a personalized treatment plan, measured to the millimeter, to achieve your desired result.
Invisible, Aesthetic
The primary advantage of transparent aligners / invisible clear aligners is their discretion. Made from removable thermoplastic, they are nearly invisible due to their transparency, offering a far superior aesthetic compared to traditional braces. This discretion, especially appealing to adults, makes it easier to start treatment. The process is aesthetic, minimally intrusive, and effectively corrects misaligned teeth to restore proper occlusion, a smile you’ll love, improved chewing, and may even reduce neck pain or headaches caused by dental misalignment. During treatment, you can eat, laugh, and speak normally without any issues, as the treatment remains discreet.
Another Advantage:
Invisible orthodontic treatment with transparent aligners is faster than traditional braces.
Removable
The invisible orthodontic device for adults using transparent aligners is fully removable. However, it’s essential to wear them almost all day to achieve the desired result. This allows you to eat and drink whatever you like, as the aligners are removed during meals. You won’t face the dietary restrictions typical of traditional orthodontic appliances, and there’s no worry about food getting stuck.

What’s the price Cost / Fees for Discreet Orthodontic Care for Adults and Kids with Clear Aligners in Luxembourg :
The expense of orthodontic therapy fluctuates based on the length of the process, the intricacy of the case/number of aligners needed, and the degree of tooth misalignment/crookedness. Dental alignment treatments are typically reimbursed by most health insurance plans, including those for French and Belgian workers residing near the border. Regarding adult orthodontic care in Luxembourg, certain additional health coverage options/mutual funds may offset a large share of the treatment expenses, with repayment levels differing according to the insurer and policy, applied post-initial reimbursements.
A visit to the dental clinic is essential to arrange for a dental check-up and clinical review. In 2024, the price for an adult orthodontic procedure using clear aligners at our Luxembourg facility is roughly **€350 per month**, payable over a year, leading to an out-of-pocket cost of approximately **€3,000** after insurance reimbursements (e.g., CMCM Dentaplus, DKV, etc.).
For Cross-Border Employees: :
The Luxembourg National Health Fund (CNS) covers orthodontic treatments and dental services for French, Belgian, Portuguese, and German workers based in Luxembourg, as well as their children.
CNS Reimbursement for Children’s Orthodontics in Luxembourg:
The cost of a dental appliance in Luxembourg varies depending on the chosen treatment: metal braces, ceramic brackets, or aesthetic orthodontic care with invisible clear aligners. Payment for the orthodontic semester can be split into installments at our clinics. A discreet orthodontic treatment to correct one or two teeth might last 6 months and will naturally cost less than a more complex case requiring additional aligners. Each situation is unique and requires a clinical and 3D analysis. The CNS reimburses around **€520 per semester** for orthodontic treatments for children under 17, while adults are only eligible for orthodontic care reimbursement through supplementary health insurance/mutual funds or private insurance.
What is the Cost of Adult Orthodontic Treatment in Luxembourg?
The price of an invisible adult orthodontic treatment in Luxembourg depends on the complexity of the case, the number of teeth and arches to align, and other bone-related factors, which will be assessed via X-rays and by the dentist. At our practice, the cost of adult orthodontic treatment generally starts at around **€2,500** for a straightforward anterior arch alignment. This price is indicative only. These figures do not include potential coverage by supplementary health insurance or flexible payment options; some private insurers may cover up to 50% of adult treatment costs. Misaligned or poorly positioned teeth can lead to significant occlusal issues, cavities, or periodontal problems, sometimes delaying the start of treatments.
CNS and Reimbursements:
Dental care for both adults and children, as well as orthodontic treatments for kids, are reimbursed by the Luxembourg National Health Fund (CNS). During an orthodontic treatment or dental procedure, our dental practice, along with the doctors and assistants, will support and guide you, assisting with the paperwork and scheduling with the CNS to ensure prompt reimbursement for services rendered.
If you’re in a hurry and want to start treatment with partial reimbursement from private insurance, it’s recommended to subscribe as soon as possible to a mutual plan like CMCM with the Dentaplus package, for example.
For Children: Is Early Orthodontic Intervention Covered?
Early orthodontic intervention is reimbursed by the CNS (Luxembourg National Health Fund).
What is Early Orthodontic Intervention?
Early orthodontic intervention aims to address tooth misalignment, improper occlusion, or poor dental posture in young patients. This proactive orthodontic approach seeks to restore normal jaw and tooth development during growth. Consequently, if a dental irregularity is evident, interception treatment should begin as early as possible, sometimes starting at age 4 and ideally before age 12.
In all cases, the orthodontist collaborates closely with the child, who will use fixed or removable devices to prevent issues such as:
– Limited transverse maxillary growth due to a lateral crossbite;
– Mandibular deviation, potentially shifting the chin due to a crossbite;
– Overbite or underbite of the incisors hindering jaw growth;
– Underdeveloped upper or lower jaws.
When is Early Orthodontic Intervention Needed?
This treatment is recommended for children aged 4 to 12 showing signs of misalignment, occlusion problems, dysfunction, or abnormal jaw and tooth growth. Specifically, it may be used for restricted maxillary growth from a lateral crossbite, mandibular deviation with a displaced chin, overbite/underbite of incisors blocking jaw development, or insufficient jaw growth.
The Importance of Interception
Initiated early, interception corrects dysfunctions more effectively, preventing worsening malocclusion. It can also address gaps between upper and lower incisors (open bite), where upper teeth barely cover lower ones, potentially worsening due to forward tongue movement.
Benefits of Early Orthodontic Intervention
The key advantage is early action, correcting initial dental anomalies to avoid more severe issues. This can save on future orthodontic or orthognathic surgery costs if untreated irregularities escalate, impacting overall dental and child health. Since teeth are linked to breathing, swallowing, and chewing, intercepting problems also prevents related functional issues.
How Does Early Orthodontic Intervention Work?
A initial visit to the orthodontist is required to assess the child’s jaw and teeth for a preliminary diagnosis. If early misalignment is detected, the orthodontist designs an appropriate interception device. This may involve X-rays and 3D dental impressions. The orthodontist then installs a fixed device or ensures proper fit and wear of a removable one, providing instructions on tooth brushing, device use, and cleaning. Regular check-ups monitor progress, and post-treatment follow-up determines if further appliances or teenage treatment are needed.
Effects and Cost of Early Orthodontic Devices for Children:
Interception stimulates growth and corrects functional issues, restoring balance for a more natural development of permanent teeth. In Luxembourg, an initial consultation diagnoses the need for interception, with a comprehensive file (photos, painless 3D digital impressions with a kid-friendly camera, X-rays) prepared by the clinic and submitted to the CNS. Approval typically takes 2-3 months, followed by device installation and spaced control appointments. Mutual funds (e.g., DKV, CMCM, Foyer) and the CNS cover nearly all costs, with any remaining balance spread over months, reducing parental out-of-pocket costs to a few dozen euros monthly. This short treatment can improve chewing and development.
After Orthodontic Treatment? Retention Phase
A custom retention wire, crafted in Luxembourg using a digital wire bender after 3D impressions, is bonded behind the teeth to maintain alignment. Dr. Arnould also provides custom night-time retention aligners for added stability. If teeth shift, reusing the final aligner set restores alignment, ensuring a stable, repeatable result.
What to Do if a Retention Wire or Retainer Breaks?
A wire may detach over time due to hard food, strong chewing, bruxism, or tongue habits. If this occurs, wear the custom retainer to maintain position. For a broken wire, schedule a prompt appointment for the dentist to address it comfortably.
