Discreet orthodontics starts with an individual decision
Many adults would like straighter teeth or a more functional bite while keeping treatment as unobtrusive as possible in their professional and private lives.
Several discreet solutions are available today. Clear aligners and lingual braces are among the options most frequently compared. Both methods can be used to plan tooth movement precisely. They differ considerably, however, in how they are worn, how much daily cooperation they require and which clinical situations they can address. Visibility alone therefore cannot determine the best choice. Your teeth and bite, your treatment goals and your lifestyle all matter.
Dr Marju Vunder has many years of experience in treatment with lingual braces and is one of the few orthodontists in Zurich to offer this highly precise treatment on a regular basis.
What are lingual braces?
Lingual braces are a fixed appliance attached to the inner surfaces of the teeth. This makes them virtually invisible from the outside. Custom-made brackets and wires apply the planned forces continuously.
Because the appliance remains fixed in place, it works around the clock and does not depend on remembering to wear it. This can be an advantage for more complex tooth movements or demanding bite corrections. Cleaning behind the teeth requires a careful routine, and the tongue and speech may need time to adapt at the beginning. The adjustment period varies from person to person and usually becomes easier with familiarity.
Lingual treatment requires detailed diagnostics, digital planning and specific clinical experience. At VUNDER ORTHODONTICS, lingual orthodontics is one of the practice’s areas of specialist expertise.
How do clear aligners work?
Aligners are removable, transparent plastic trays. A sequence of carefully coordinated trays moves the teeth step by step towards the planned position. They are taken out for eating, drinking and cleaning the teeth. Many patients appreciate their discreet appearance and the ability to maintain a familiar oral-hygiene routine.
Reliable results nevertheless depend on very consistent wear – usually for at least 22 hours a day. Visible attachments, small tooth-coloured elements bonded to selected teeth, or elastics may be required as part of the treatment plan.
Aligners are suitable for many corrections, but they are not equally appropriate for every tooth or bite problem. Some movements can be controlled or predicted more reliably with a fixed appliance. A specialist orthodontic examination will establish whether aligner treatment is a sound option in your situation.

The key differences in daily life
With lingual braces, there is no appliance to remember to put back in. They remain active while you eat and throughout long working days. Cleaning the inner surfaces of the teeth is more demanding, however, and certain hard or sticky foods should be avoided.
Aligners can be removed for meals and toothbrushing. That flexibility requires a dependable routine: after eating, the teeth are cleaned and the trays are put back in. Leaving aligners out for extended periods can delay the planned progress.
The meaning of “invisible” also differs. Lingual brackets sit entirely behind the teeth. Aligners are transparent but may be noticeable at close range, particularly when attachments or elastics are used.
Which method is right for you?
A well-founded decision considers more than appearance. During a consultation, we assess:
- the tooth movements and bite correction required;
- the complexity of the starting situation;
- how important a removable option is in your daily life;
- whether at least 22 hours of daily wear is realistic;
- which aspects of oral hygiene, comfort and speech matter most to you.
Sometimes one method is clearly more appropriate. In other cases, both are possible and personal priorities guide the choice. The important point is that the appliance should do more than look discreet: it should control the planned movements and support stable conditions for the long term.
Precise planning for a result that suits you
Treatment begins with a careful assessment of the teeth, jaws, bite and gum health. We then discuss the realistic options, the anticipated process and the respective advantages and limitations. After active treatment, retainers stabilise the new tooth positions, regardless of whether the teeth were moved with aligners or lingual braces.

Frequently asked questions
Are lingual braces truly invisible?
The brackets and wires are fitted to the inner surfaces of the teeth and are virtually invisible from the outside when speaking or smiling. Depending on how widely the mouth is opened and the viewing angle, an individual component may occasionally be seen.
Are aligners always the more comfortable option?
Comfort is individual. Aligners may create pressure at first and must be worn consistently. Lingual braces may temporarily irritate the tongue or affect speech. Which option feels easier in daily life depends on your priorities and how you adapt.
How long does treatment take?
Duration depends on the starting situation, the treatment goals, the chosen appliance and the biological response of the teeth. A reliable estimate can only be given after a diagnostic assessment.
