Short answer: Lingual braces are a fixed orthodontic method in which the brackets are bonded to the inner, tongue-side surfaces of the teeth, so they cannot be seen from the outside. Their advantage is that they depend less on patient compliance. On the other hand, temporary speech changes and tongue irritation may occur in the first weeks, cleaning is harder, and because they are custom-made, the cost is usually higher.
Lingual braces are a fixed orthodontic method in which the brackets are bonded to the inner, tongue-side surface of the teeth instead of the front surface. Because the brackets are not visible when someone looks at you, they are also popularly called "invisible braces." In this article we look at who this method, popular among adults with aesthetic concerns, is suitable for, what the adjustment period is like, its pros and cons, and how it differs from clear aligners.
What are lingual braces?
Lingual braces are an orthodontic appliance that stays fixed in the mouth throughout treatment, made up of brackets bonded to the inner surfaces of the teeth and wires attached to those brackets. Lingual orthodontics relies on the same biological principle as conventional fixed treatment: the wires apply a continuous, controlled force to the teeth, the bone remodels in response to this force, and the teeth slowly move to their planned positions.
The inner surfaces of the teeth have a more irregular anatomy than the front surfaces, and it varies greatly from person to person. For this reason, lingual brackets are often custom-designed from the patient's impressions or digital scan, and the wires are bent according to this plan. The brackets are bonded in the mouth in one go and in the correct position using a transfer tray prepared in the laboratory.
Who are they suitable for?
Lingual braces can be considered for teenagers and adults with healthy teeth and gums who want an orthodontic appliance that is not visible at all from the outside and who prefer a fixed system. People who speak a lot for their work, appear on camera, or want to avoid the appliance being noticed in their social life may ask about this method.
The suitability assessment looks at the following points:
- Inner surface anatomy of the teeth: Treatment can be more difficult with teeth that have very short crowns or inner surfaces that are not well suited to bonding brackets.
- Bite type: In people with a deep bite, the lower front teeth may touch the upper brackets; in this case the orthodontist plans additional measures.
- Oral hygiene: Because cleaning the inner surfaces takes more effort, a regular brushing habit is important.
- Gum and bone health: Any active gum disease must be treated first.
- Expectations and adjustment: Being prepared for the speech changes and tongue sensitivity of the first weeks makes the process easier.
Advantages
The most obvious advantage of lingual braces is aesthetics: because the brackets sit behind the teeth, they cannot be seen from the outside when you smile or talk. There are other advantages as well:
- Less dependence on patient compliance: Because the appliance is fixed, there is no risk of forgetting to wear it; the force is applied continuously.
- Protection of the front enamel: Because there are no brackets on the front surfaces, any white spots that may form around the brackets are not visible in the smile zone.
- Wide range of cases: As a fixed system, they can be used for crowding, gaps and many bite problems.
- Custom manufacturing: Designing the brackets and wires individually allows the treatment plan to be worked out in detail.
Disadvantages: speech, cleaning, cost
The main disadvantages of lingual braces are temporary speech changes and tongue irritation in the early period, more difficult cleaning on the inner surfaces, and a cost that is usually higher than conventional braces because of the custom manufacturing.
Speech and tongue sensitivity
When you speak, your tongue constantly touches the inner surfaces of your teeth. When brackets are placed in this area, a slight lisp may occur, especially with sounds such as "s," "sh," "z" and "t." For most people this decreases noticeably within a few weeks as the tongue adapts to its new environment. During this time, sores and sensitivity caused by friction may appear along the edges of the tongue. Orthodontic wax recommended by your orthodontist and rinsing with warm salt water can bring relief.
Cleaning
Because the inner surfaces of the teeth cannot be seen without a mirror, it is hard to notice plaque building up around the brackets. Aids such as a small-headed toothbrush, interdental brushes, special floss that can be threaded under the wire and a water flosser make cleaning easier. Regular professional cleaning appointments may also be recommended.
Cost and the orthodontist's experience
Because lingual systems require a custom laboratory process and take more clinical time to place, they usually cost more. It should also be noted that the method requires special training and experience. The treatment fee differs in every case and is provided in writing after the examination and planning.
Eating and drinking
As with all fixed systems, very hard, sticky and gum-like foods can cause brackets to come off. You should avoid habits such as cracking nuts in their shells, eating hard candy and chewing ice.
Lingual braces or clear aligners?
Lingual braces and clear aligners serve a similar purpose in being barely visible; their basic difference is that lingual braces are fixed while clear aligners are removable, and this difference is often decisive in the choice. To learn more about clear aligners, see our article what are clear aligners.
- Visibility: Lingual braces are not visible when someone looks at you. Clear aligners are transparent and do not stand out even at close range; small tooth-colored attachments, if any, may be noticed up close.
- Speech: With lingual braces there may be a noticeable adjustment period in the first weeks. With clear aligners, the change is usually brief and milder.
- Oral hygiene: Because clear aligners are removed, your brushing and flossing routine does not change. Lingual braces require extra tools and more time.
- Diet: Aligners are removed for meals, so there are no food restrictions; with lingual braces, hard and sticky foods are avoided.
- Compliance responsibility: Clear aligners must be worn 20–22 hours a day; lingual braces work on their own.
- Comfort: Clear aligners have no metal parts touching the tongue and cheeks; lingual brackets can irritate the tongue.
At our clinic, clear aligner treatment is provided only with Invisalign, and thanks to digital planning every stage of treatment is visualized in advance. If you would like a detailed look at the general differences between fixed braces and clear aligners, our page clear aligners or braces can help. Which method is right for you, however, only becomes clear after an examination, records and a conversation about your expectations.
Retention after lingual treatment
When lingual treatment is complete, the brackets are removed, the tooth surfaces are polished and the retention phase begins so that the teeth hold their new positions. Usually a thin fixed retainer wire is bonded to the inner surfaces of the front teeth, and a clear retainer worn at night may also be recommended. Using retainers as your orthodontist instructs reduces the tendency of the teeth to drift back to their old positions.

Frequently asked questions
Do lingual braces affect speech permanently?
Usually not. In the first weeks there may be a slight lisp, especially with s, sh and z sounds. As the tongue adapts to the new situation, this change decreases noticeably for most people.
Do lingual braces hurt?
As with all orthodontic treatments, you may feel pressure and sensitivity in your teeth in the first days and after wire changes. With lingual braces, friction-related irritation of the tongue may be added to this. Orthodontic wax and rinsing with warm salt water can help.
Is there a difference in treatment time between lingual braces and clear aligners?
Treatment time depends more on the complexity of the case and patient compliance than on the method used. With both methods, the orthodontist gives an estimated duration after the examination and planning.
Which foods should I avoid with lingual braces?
Hard nuts, hard candy, ice, chewing gum and sticky foods such as caramel can cause brackets to come off. Hard fruits and vegetables such as apples and carrots can be eaten in small pieces.
