Smile with an orthodontic appliance

Our invisible and conventional orthodontic treatments

Every situation has its answer. Here are the six approaches we offer in Luxembourg, from the most discreet to the most comprehensive.

Clear Invisalign aligner fitted on the teeth — orthodontic treatment Luxembourg Most requested

Invisalign

Suited to responsible teenagers and to adults

The aligner comes out for meals and for brushing, then goes straight back in: it is the daily wear time that determines the result. Being clear, it goes unnoticed.

Metal orthodontic braces on teeth — orthodontics Luxembourg

Metal braces

Recommended in particular for teenagers

The most robust solution, correcting even complex cases with a predictable result.

Tooth-coloured ceramic orthodontic braces — orthodontics Luxembourg

Ceramic braces

Recommended in particular for teenagers

The strength of conventional fixed braces, without the metallic contrast: the brackets blend into the colour of your teeth.

Interceptive orthodontic appliance for a child — orthodontics Luxembourg

Interceptive

Generally between the ages of 6 and 12

Early care, generally between the ages of 6 and 12, when growth or dental development justifies it: the jaw is guided while it is still growing, which often means less treatment to deal with later on.

Lingual braces fitted behind the teeth — invisible orthodontics Luxembourg

Lingual

Suited to some teenagers and to adults

Fitted behind the teeth: nobody can see that you are in treatment, not even close up. A particularly discreet solution, suited to some teenagers and to adults when the case lends itself to it.

Bonded orthodontic retainer fitted behind the teeth — orthodontics Luxembourg

Retention

Recommended for all patients at the end of treatment

Recommended for all patients at the end of treatment, to stabilise the results achieved: it keeps your teeth aligned, years afterwards.

Who is it for?

Orthodontics — Children

Children

6–12 years

Interceptive orthodontics, to guide growth and correct early.

Orthodontics — Teenagers

Teenagers

12–18 years

Fixed braces or Invisalign Teen, at the ideal moment to treat.

Orthodontics — Adults

Adults

no age limit

Discreet clear aligners and lingual braces, entirely discreetly.

The right time to treat depends on growth, not on age alone. The initial assessment is what determines it.

Day to day

Living with your orthodontic appliance

Orthodontic treatment succeeds on two conditions: the team’s work, and yours. The duration given at the initial assessment assumes appointments kept, an appliance worn as prescribed and a suitable diet. Here is what changes in practice, day to day.

The 5 keys to success

  1. Tell us what is going on

    Tell us what is bothering you, what has broken, what you have not been able to wear. Treatment is carried out with you, not despite you.

  2. Good hygiene

    Careful brushing after every meal, above and below the wire, completed with an interdental brush.

  3. Wear your appliance

    Clear aligners, elastics, removable appliance: the wear time prescribed directly determines the result and how long it takes.

  4. Keep to your appointments

    A missed session puts back the next adjustment and adds several weeks to the treatment.

  5. Watch what you eat

    Avoid foods that pull brackets off or break the appliance, and cut things into pieces rather than biting into them.

Foods and habits to avoid

  • Sticky or soft foods

    They pull brackets off. Eaten regularly, they reduce the effect of each adjustment and lengthen the treatment.

  • Foods that are too hard

    They break the appliance. Every breakage means a repair session that does not move the treatment forward.

  • Bad habits

    Do not bite straight into an apple or a sandwich: cut them into pieces. Do not bite your nails or chew on a pen.

If the appliance breaks

Without pain

A wire sticking out, a bracket that has come off, a broken elastic: call us and a repair appointment will be arranged for you. In the meantime, orthodontic wax placed on the part that is rubbing is enough to relieve it — we give you some when the appliance is fitted.

With pain

It hurts, it is bleeding, it is swelling: call us straight away and we will see you quickly. Never try to cut a wire or re-attach a bracket yourself.

Frequently asked questions about orthodontics

Why consult us 4 questions
Why have orthodontic treatment?

The aim is not only aesthetic. Aligning the teeth improves chewing, makes brushing and access between the teeth easier, and helps preserve the health of the teeth and gums over the long term. A well-aligned dentition is easier to look after and wears more evenly. The aesthetic benefit is real, but it comes on top of a functional one.

Can misaligned teeth have consequences for your health?

Yes. Teeth that overlap, or that meet badly, are harder to clean: the brush and the floss do not reach certain areas. That encourages tooth decay and inflammation of the gums. The way such teeth meet also causes abnormal wear of the enamel and, in some cases, muscle or joint pain in the jaw.

Might my child need monitoring without immediate treatment?

Yes, and it is common. The orthodontist may spot a problem while judging that the right moment to act has not yet come: they then propose simple monitoring, with widely spaced check-ups, until the most favourable window. Treating too early lengthens the treatment needlessly; treating too late can make it more complicated.

Can I carry on with my activities as normal during treatment?

In most cases, yes. Work, sport, singing, playing a wind instrument, social life: the treatment does not interrupt them. A short period of adjustment is common in the first few days, however, particularly for wind instruments and for speech. Tell us what you do at the assessment stage: it may guide the choice of technique.

Before you start 9 questions
At what age should you take your child to an orthodontist?

A first assessment is recommended at around 7, even where nothing appears to be wrong. At that age the first permanent molars and incisors are in place and make it possible to spot a jaw discrepancy before it becomes established. An earlier consultation is justified when the dentist, the school doctor or the parents notice something unusual — a problem with jaw growth sometimes comes before any visible misalignment.

What happens at the first appointment?

The first appointment is above all about listening: what brings you here, what bothers you, what you expect from treatment. A clinical examination of the teeth, the gums and the jaws follows, together with the way the teeth meet. The orthodontist then decides whether further examinations are needed to reach a full diagnosis.

What examinations may be carried out before treatment?

Depending on the situation: X-rays — a panoramic X-ray and a lateral cephalogram at the very least, sometimes a Cone Beam 3D scan —, intraoral and extraoral photographs, and impressions or a 3D digital scan. These examinations record the starting point: they are used to draw up the treatment plan, and then as the reference against which its result is measured. They are carried out at Luxembourg-Merl.

How is the treatment plan drawn up, and is it tailored to me?

Once the assessment has been analysed, the orthodontist sets out the diagnosis, the goals, the technique envisaged and an estimate of how long it will take. The plan is specific to each patient: it depends on age, on the position of the teeth and jaws, on the condition of the gums, but also on your aesthetic expectations and your personal constraints. It is explained to you beforehand, not applied without discussion.

From what age can orthodontic treatment begin?

Early treatment may be proposed in childhood, in order to work with jaw growth while it is still active — which is precisely what the assessment at 7 is there to detect. In teenagers, treatment acts on both the jaws and the permanent teeth. In adults, most misalignments can also be corrected: there is no age limit.

Can an adult have orthodontic treatment?

Yes. Most misaligned teeth can be corrected in adulthood, mainly with clear aligners or the lingual technique. In some cases involving a significant jaw discrepancy, surgery may however be needed alongside the orthodontics. The initial assessment establishes whether your situation can be dealt with by orthodontic treatment alone.

Invisalign clear aligners or fixed braces: how do you choose?

The choice is made on the clinical case, not on preference. Clear aligners cover most mild to moderate corrections and come out for eating and brushing. Fixed braces, metal or ceramic, remain the reference for significant rotations and complex cases. The lingual technique, bonded behind the teeth, stays invisible from the front. The initial assessment decides.

What has to be in place before treatment can start?

Three conditions must be met: the written treatment estimate signed, the terms and conditions signed, and — for children covered by the health insurance fund — the fund’s approval received. In addition, any tooth decay must be treated before the appliance is fitted. No treatment starts without these documents having been discussed with you.

Does tooth decay have to be treated before starting?

Yes, in every case. All tooth decay must be treated by your general dentist before orthodontic treatment begins. A decayed tooth under an appliance becomes far harder to treat, and the appliance sometimes has to be removed to reach it. That is why we ask for an up-to-date dental check-up before fitting.

The appliances 4 questions
What types of orthodontic appliance are there?

Five families, according to the clinical case: the conventional fixed appliance with metal brackets; ceramic brackets, tooth-coloured and more discreet; the lingual appliance, bonded behind the teeth; removable clear aligners; and the removable appliance, used in particular in children having interceptive treatment. Several may be combined or follow one another within the same treatment.

What is the difference between a conventional and a lingual appliance?

The surface of the tooth it is bonded to. The conventional appliance is fitted on the outer surface, visible when you smile. The lingual appliance is fixed on the inner surface, on the tongue side: it stays invisible from outside, even close up. In return, it calls for a more noticeable period of adjustment for speech and for brushing.

Can every patient choose an invisible appliance?

No, not in every case. The choice depends first on what has to be corrected: certain rotations and certain large movements are treated better, or only, with fixed brackets. It then depends on what is technically feasible in your case, and on the level of cooperation required — clear aligners only work if they are worn for the number of hours prescribed.

Will I have difficulty speaking with an appliance?

Some difficulty with speech is possible in the first few days, especially with a lingual appliance or an aligner, as the tongue has to get used to a new volume. It usually eases gradually over one to two weeks. Reading aloud for a few minutes a day speeds up the adjustment noticeably. If you sing or play a wind instrument, tell us before the technique is chosen.

How treatment unfolds 7 questions
How does orthodontic treatment unfold?

Treatment generally has two phases. The active phase, during which the appliance moves the teeth, with regular check-ups to adjust the forces applied. Then the retention phase, which holds the result achieved while the bone consolidates around the teeth. Both phases are part of the treatment: one without the other does not last.

How long does orthodontic treatment take?

On average 12 to 24 months for the active phase, followed by two years of retention. The length depends on the complexity of the case, on the patient’s growth and on how closely the orthodontist’s instructions are followed. Mild cases can be corrected in 6 to 10 months; complex cases treated with the lingual technique take longer. The initial assessment gives you an estimate.

How often do you have to come in for a check-up?

The frequency depends on the type of treatment, on the appliance used and on your orthodontist’s recommendations: it is set case by case and given to you at the start of treatment. These appointments are not simple checks — it is at these sessions that the appliance is adjusted. A missed session therefore puts back the next adjustment and lengthens the treatment.

Is it painful to wear an orthodontic appliance?

Fitting is not painful and needs no anaesthetic. Temporary sensitivity of the teeth or of the soft tissues may appear during the first few days after fitting and after each adjustment: it is the sign that the teeth are moving. It usually fades gradually, and an ordinary painkiller is enough to relieve it. Do tell us about any pain that lasts abnormally long.

Are X-rays needed during treatment?

Yes. X-ray checks may be taken during treatment in order to follow its progress and to verify the actual movement of the teeth and roots — which clinical examination alone cannot show. These examinations are carried out at the Cabinet d’Imagerie Dentaire, at Luxembourg-Merl, on referral from your orthodontist.

How do you check that treatment is progressing properly?

By comparing, at each check-up, the actual position of the teeth and jaws against the goals set at the start of treatment — not against the previous session. Photographs, digital scans and, where necessary, X-rays document that progress. When the gap widens, the plan is adjusted: that is precisely what these appointments are for, beyond adjusting the appliance.

What happens when the appliance is removed?

Debonding has several stages: removing the appliance, cleaning off the residual adhesive, then polishing and buffing the teeth to restore smooth enamel. A second appointment is sometimes needed to finish the polishing. Retention is put in place straight afterwards: the result is not stable until it is fitted.

Hygiene and daily life 8 questions
Why does hygiene matter so much with an appliance?

Because an appliance makes brushing considerably harder, and because poor hygiene during treatment leaves permanent damage: irreversible marks on the enamel, tooth decay, inflammation or gum recession. Allow at least two minutes after every meal, above and then below the wire, bracket by bracket, completed with an interdental brush. It is the main avoidable risk of the treatment.

Should I keep seeing my general dentist?

Yes. A check-up with your general dentist remains recommended every six months throughout the orthodontic treatment. We follow the movement of the teeth; your dentist follows their state of health. The two are complementary and neither replaces the other — decay caught early saves having to remove the appliance to treat it.

Do you work with the patient’s regular dentist?

Yes, whenever the situation calls for it. Orthodontic follow-up is coordinated with your general dentist and, where relevant, with a periodontist, an oral and maxillofacial surgeon or a practitioner specialising in implants. A clinical report is sent to your regular dentist, and any imaging carried out here is sent to them directly. You do not have to pass the documents around yourself.

Are some foods best avoided with an appliance?

Yes, two families cause problems. Sticky or soft foods — chewing gum, toffees, nougat, sweets, sugary drinks — pull brackets off, reduce the effect of each adjustment and encourage tooth decay. Foods that are too hard — peanuts, nuts, very hard sweets — break the appliance. Otherwise, cut things into pieces rather than biting straight into an apple or a sandwich.

What habits can compromise the treatment?

Thumb sucking, nail biting, tongue thrust against the teeth and mouth breathing can disrupt the treatment or encourage a relapse once it has finished. To these can be added chewing on a pen or an object, which pulls brackets off. Do tell us about these habits: some can be corrected, and that is part of the treatment.

What should I do if my appliance is broken or damaged?

Contact the clinic promptly. The repair should ideally happen within ten days: beyond that, a damaged appliance causes uncontrolled tooth movement and lengthens the overall treatment. If there is no pain, a repair appointment is arranged. If there is pain, bleeding or swelling, we will see you quickly. Never cut a wire yourself.

What happens if I do not wear my aligners or elastics properly?

The treatment slows down, loses effectiveness and takes longer. Clear aligners and elastics only work during the wear time prescribed: a few hours missed each day are enough to put the whole treatment plan back. Where cooperation is insufficient, or where there is a risk to your health, the orthodontist may decide to stop the treatment.

What if I am away for a long period?

Tell the clinic in advance. A long stay abroad, a temporary move or a period of immobility are all easily managed provided they are anticipated: we adapt the follow-up and, if necessary, the appliance, before you leave. An unannounced interruption, on the other hand, harms the treatment and may mean going back over certain stages.

Retention 5 questions
What is retention in orthodontics?

It is the phase that follows removal of the appliance. It stabilises the teeth in their new position while the bone consolidates around them. Without retention, teeth have a natural tendency to drift back towards their original position, whatever the age and whatever the technique used. Retention is not an optional extra: it is what makes the result last.

What types of retention may be proposed?

Two forms, sometimes combined. A bonded retainer behind the teeth, invisible and permanent, which asks nothing of you day to day. Or a removable retainer, worn at night as prescribed. The choice depends on the initial clinical situation and on the risk of relapse in your particular case; it is explained to you when the appliance is removed.

How long does the retention phase last?

Two years, with six-monthly check-ups. That is how long the bone needs to reorganise around the teeth in their new position. The first months matter most: that is when the risk of relapse is highest. After those two years, your orthodontist will tell you whether continuing longer is advisable in your case.

Is the retainer guaranteed?

Yes. Replacement of the retainer is guaranteed for 24 months, subject to the six-monthly check-up appointments being kept. Those check-ups are not a formality: they make it possible to confirm that the wire is intact and properly bonded, and to repair it before an unnoticed debond has let the teeth move.

What should I do if my retainer comes loose or breaks?

Contact the clinic promptly so that a check-up and, if necessary, a repair can be arranged. A wire that has come loose, even on a single tooth, leaves that tooth free to move — and the movement can be visible within a few weeks. Do not wait for the next six-monthly check-up: the sooner it is dealt with, the simpler it is.

Reimbursement and payment 2 questions
Is orthodontics reimbursed by the CNS in Luxembourg?

The Caisse nationale de santé (CNS, Luxembourg’s national health fund) covers part of orthodontic treatment for children, subject to conditions and to prior approval. Treatment for adults is generally not reimbursed by the CNS; cover may still be available through private or supplementary insurance, depending on the terms of your policy. The current rules are set out on cns.public.lu.

Will I receive a written treatment estimate before starting?

Yes, in every case. The written treatment estimate is given to you at the end of the initial assessment, before any appliance is fitted, and signing it is a condition of starting treatment. It sets out the technique chosen, the estimated duration, the total amount and any part that may be covered. No treatment begins without this document having been discussed with you.
