How do lingual braces work?
The working principle of lingual treatment is the same as that of conventional brackets bonded to the front of the teeth: the brackets are bonded to the teeth, the archwire running through them applies controlled force, and the teeth move towards their planned position. The difference is that the brackets and wire are placed on the inner, tongue-side surface of the teeth. As a result, the brackets cannot be seen from the outside when you talk or smile.
Because the inner surfaces of the teeth can vary greatly from person to person, lingual brackets are usually planned on a model of the teeth and bonded using a transfer tray. For the general steps of fixed treatment, see our fixed braces treatment page.
Who are they considered for?
Lingual braces are one of the options for patients who need fixed treatment and for whom it matters that the brackets are not visible from the outside. Suitability is decided at the examination. The assessment looks at:
- The size and shape of the inner surfaces of the teeth
- The bite relationship; in a deep bite, whether the lower teeth touch the upper brackets
- Gum health and oral hygiene habits
- Treatment goals and the patient's expectations
Effects on daily life
Speech
Because the brackets sit in the area where the tongue moves, you may notice a change in how some sounds come out in the first days. The tongue usually adapts to the new situation over time; how long this takes varies from person to person. Reading aloud and practising speaking can make it easier to adjust.
How the tongue and cheeks feel
In the first days, the tongue rubbing against the brackets can cause tenderness. Using orthodontic wax can bring relief during this period. If a sore spot lasts a long time or a wire is poking, let the clinic know; for details, see the orthodontic emergencies page.
Eating
As with fixed braces in general, hard, sticky foods and foods that need a lot of chewing should be avoided. For a recommended eating routine, take a look at the eating with braces guide.
Care
The inner surface of the teeth is an area that is hard to see in the mirror, so cleaning needs a little more attention. It is important to clean carefully around the brackets every day with a soft toothbrush, an interdental brush and any additional cleaning aids your orthodontist recommends. Oral hygiene is also checked at regular check-ups.
Lingual braces, ceramic brackets and clear aligners
- Lingual braces: A fixed system that is not visible from the outside. They cannot be removed; cleaning and getting used to speaking need attention.
- Ceramic brackets: These sit on the front of the teeth; because their colour is close to that of the teeth, they are less noticeable than metal brackets. For details, see the ceramic brackets page.
- Clear aligners: Removable; they are taken out for eating and brushing and need to be worn for most of the day. For details, see the clear aligners or braces page.
Which method suits you is assessed together at the examination, based on the condition of your teeth, your treatment goals and your daily habits.
Frequently asked questions
Are lingual braces really invisible?
Because the brackets are on the inner surface of the teeth, they are not visible from the outside during normal speaking and smiling. They may be noticed when the mouth is opened wide or when someone looks very closely.
Is the treatment time different?
Treatment time depends largely on how complex the situation of the teeth and jaws is. The time for your own case is discussed after the examination and treatment plan.
Can they be used for every patient?
No. Depending on factors such as tooth shape, bite and oral hygiene, they may not be suitable for every patient. Suitability is decided at the examination.
