Lingual braces are fixed orthodontic braces that are bonded to the back surfaces of the teeth, facing the tongue, rather than to the front. Because the brackets and wires sit on the inside of the dental arch, they are almost invisible when you smile or speak. They work in the same basic way as conventional braces, applying gentle, continuous pressure to move teeth into better positions, and they can treat a wide range of alignment and bite problems. They are often chosen by teenagers and adults who want the precision of fixed braces without visible metalwork, though they can take some getting used to and usually require specialist planning.
Key takeaways
- Lingual braces are attached to the inner surfaces of the teeth, so they are hidden from view in everyday life.
- They can correct many of the same problems as traditional braces, including crowding, gaps and certain bite issues.
- Many lingual systems are custom-made for each patient using digital scans and tailored brackets and wires.
- Tongue soreness and temporary changes to speech are common in the first few weeks, but most people adapt.
- Cleaning takes extra care, and not every case or every mouth is suitable, so a thorough orthodontic assessment is essential.
How do lingual braces work?
Lingual braces follow the same principles as any fixed brace. Small brackets are bonded to each tooth, and an archwire runs through them. The wire is shaped to represent the ideal final position of the teeth, and as it tries to return to that shape, it applies light, steady force. Over time, this pressure encourages the bone around each tooth to remodel, allowing the teeth to move gradually into their new positions. Elastics, springs and other auxiliaries can be added to fine-tune the movement or correct the bite.
The key difference is placement. Because the brackets are on the tongue side of the teeth, the orthodontist works on the inner surfaces, which are smaller and more varied in shape than the front surfaces. For this reason, many lingual systems use brackets that are individually designed for each tooth, and wires that are bent precisely by computer-guided equipment. This customisation helps the brace fit closely and deliver accurate tooth movement, even though the orthodontist is working in a more confined space than with conventional braces.
What problems can lingual braces fix?
Lingual braces can treat most of the orthodontic problems that front-facing braces can. These include crowded or overlapping teeth, gaps between teeth, rotated teeth, and many types of bite irregularity such as overbites, deep bites and some crossbites. Because they are fixed to the teeth and work full-time, they can produce complex movements, including moving roots and changing the vertical position of teeth, which can be more challenging with some removable systems.
That said, suitability depends on the individual. Very short teeth may not offer enough surface area on the back to hold a bracket securely. Some severe bite problems, or cases requiring significant jaw correction, may be better suited to a different approach or a combination of treatments. People with a very deep overbite may also find that the lower teeth contact the upper lingual brackets, although orthodontists have ways of managing this. A detailed assessment, including scans, photographs and X-rays, will show whether lingual braces are a sensible option for your teeth and goals.
How are lingual braces different from clear aligners?
Both lingual braces and clear aligners are popular with people who want discreet treatment, but they work in very different ways. Clear aligners are a series of removable plastic trays that are changed regularly, each one moving the teeth a small step. They must be worn for most of the day and night to be effective, and they are removed for eating, drinking anything other than water, and cleaning. Lingual braces, by contrast, are fixed in place and cannot be taken out, so they work continuously without relying on the wearer’s discipline.
This difference can be significant. For people who worry that they might not wear aligners consistently, a fixed lingual brace removes that uncertainty. Lingual braces may also be preferred for certain complex movements that aligners find more difficult. On the other hand, aligners allow normal eating and easier cleaning, and some people find them more comfortable for the tongue. Neither option is universally better. The right choice depends on the type of correction needed, lifestyle, comfort preferences and the orthodontist’s recommendation after examining your teeth.
What does the fitting process involve?
Treatment usually begins with a consultation and a set of records, which often includes a digital scan or impressions of the teeth, photographs and X-rays. These are used to plan the final tooth positions and design the brackets and wires. With customised lingual systems, there is typically a waiting period of a few weeks while the appliance is manufactured, because each bracket base is shaped to match the back of a specific tooth.
On the fitting day, the teeth are cleaned and prepared, and the brackets are positioned using a precise transfer tray so they land exactly where planned. A special dental adhesive bonds them in place, and the archwire is then attached. The appointment can take a little longer than a conventional brace fitting because of the careful positioning required. Afterwards, the orthodontist will explain how to clean around the brace, what to eat in the first few days and what to do if a wire or bracket feels uncomfortable. Regular adjustment visits follow throughout treatment.
Do lingual braces affect speech and comfort?
Because lingual brackets sit where the tongue naturally rests and moves, they can affect speech at first. Many people notice a slight lisp or difficulty with certain sounds, particularly those that involve the tongue touching the back of the upper front teeth. This is usually temporary. The tongue is remarkably adaptable, and most people find their speech returns to normal within a few weeks as they get used to the new shape inside their mouth. Reading aloud and practising tricky words can speed up the adjustment.
Tongue soreness is the other common early complaint. The edges of the brackets can rub the tongue until it toughens up, which typically happens over the first couple of weeks. Orthodontic wax can be placed over any sharp areas, and saltwater rinses can soothe irritation. Some modern lingual brackets are designed with a low profile and smooth contours to reduce discomfort. Like all braces, there may also be a general aching of the teeth for a few days after fitting and after each adjustment, which usually responds well to soft foods and over-the-counter pain relief.
How do you clean and care for lingual braces?
Keeping lingual braces clean requires a little more effort than front-facing braces, simply because the brackets are harder to see. Plaque can collect around the brackets and along the gumline, and if it is left there, it can lead to gum inflammation or marks on the teeth. Brush carefully at least twice a day, angling the toothbrush to reach the brackets on the inner surfaces. Many people find a small-headed or single-tufted brush helpful for getting into these areas, and an electric toothbrush can make thorough cleaning easier.
Cleaning between the teeth is just as important. Interdental brushes, floss threaders and water flossers can all help remove food and plaque from around the wire. A mirror is useful at first so you can see what you are doing. It is also wise to limit sugary and acidic foods and drinks, avoid very hard or sticky foods that might damage the brace, and use a fluoride toothpaste to protect the enamel. Your orthodontist or hygienist can show you techniques that suit your mouth and point out any areas that need more attention.
How long does treatment with lingual braces take?
Treatment time with lingual braces is broadly similar to that of conventional fixed braces, and it depends mainly on the complexity of the case rather than the type of appliance. Mild crowding or spacing might be corrected relatively quickly, while more involved bite corrections take longer. For many people, treatment lasts somewhere between one and two and a half years, although your orthodontist will give you a personalised estimate after assessing your teeth.
Adjustment appointments are usually spaced every few weeks to allow the orthodontist to change wires, check progress and make fine adjustments. Keeping these appointments and caring for the brace properly helps treatment stay on track. Breakages, such as a loose bracket, can slow progress, so it is worth avoiding habits like chewing pens or biting into very hard foods. Once the teeth are in their final positions, the brace is removed and retainers are provided to keep the teeth stable. Retention is an essential part of any orthodontic treatment, regardless of the brace used.
Are lingual braces the right choice for you?
Lingual braces can be an excellent choice for people who want the reliability and control of fixed braces but prefer that nobody can see them. They are particularly popular with adults in client-facing roles, performers, musicians who play certain wind instruments where front braces might interfere, and anyone who simply prefers a discreet option. Because the brackets are on the inside, any minor marks that can occasionally occur around brackets are also hidden on the less visible surfaces.
However, they are not the right fit for everyone. They tend to be more complex to fit and adjust, which is often reflected in the cost, and they require a period of adaptation for speech and comfort. Not all orthodontists provide lingual treatment, as it involves additional training and specialised systems. The most useful step is to discuss your priorities openly during an orthodontic consultation, including appearance, comfort, budget and the type of correction you need, so you can weigh lingual braces against the alternatives with full information.
Frequently Asked Questions
Can other people see lingual braces?
Lingual braces are bonded to the back surfaces of the teeth, so they are very difficult for other people to see during normal conversation or when you smile. They may occasionally be visible if someone looks directly into your mouth when it is wide open, but in everyday situations they remain hidden.
Do lingual braces hurt more than regular braces?
Lingual braces do not usually cause more tooth discomfort than regular braces, but they can make the tongue sore in the first few weeks because the brackets sit where the tongue rests. Orthodontic wax, saltwater rinses and soft foods help, and most people adapt within a couple of weeks.
Will lingual braces change the way I speak?
Many people notice a mild lisp or difficulty with certain sounds when lingual braces are first fitted. This is usually temporary, as the tongue adapts to the brackets. Speaking and reading aloud regularly can help speech return to normal, often within a few weeks of fitting.
Can anyone have lingual braces?
Many teenagers and adults are suitable for lingual braces, but not everyone. Very short teeth, some severe bite problems and certain jaw issues may make another option more appropriate. An orthodontist will assess your teeth with scans, photographs and X-rays before recommending the most suitable treatment.
Do you need a retainer after lingual braces?
Yes. As with any orthodontic treatment, retainers are needed after lingual braces are removed to stop the teeth drifting back towards their old positions. Your orthodontist may recommend a fixed retainer bonded behind the teeth, a removable retainer or a combination, along with guidance on how long to wear it.
