Most people picture metal brackets on the front of the teeth when they think about braces, but there is another option that works just as effectively while staying completely out of sight.
If you have ever wondered what are lingual braces and how they differ from traditional treatment, you are not alone. Lingual braces offer a discreet approach to orthodontic care that appeals to many adults and teens who want to correct their smile without the visible hardware of conventional braces.
What Are Lingual Braces?
Lingual braces are a type of fixed orthodontic appliance, just like traditional braces, but instead of being placed on the outer surface of the teeth, they are bonded to the inner (lingual) surface, facing the tongue. From the outside, your teeth look completely natural throughout treatment because all the brackets and wires are hidden behind your teeth.
The brackets used for lingual braces are custom-made to fit the unique contours of each patient's teeth, because the inner surface of teeth varies much more in shape than the outer surface. This customization is part of what makes lingual braces more technically demanding to place and adjust, but it is also what allows them to work effectively while staying invisible.
How Do Lingual Braces Work?
Lingual braces work using the same fundamental principles as traditional braces. Brackets are bonded to the teeth, and an archwire runs through the brackets, applying gentle, continuous pressure to guide teeth into alignment. Over time, the bone and tissue surrounding the teeth respond to this pressure, allowing the teeth to shift gradually into their correct positions.
Adjustments are made at regular appointments, where your orthodontist tightens or changes the wires to continue progressing through your treatment plan. The mechanics are essentially the same as standard braces, just applied from the opposite side of the teeth.
Lingual Braces vs Traditional Braces: How Do They Compare?
Aesthetics
The most obvious difference between lingual braces and traditional braces is visibility. Traditional braces are clearly visible on the front surfaces of the teeth, while lingual braces are completely hidden behind them. For patients whose professional or personal lives make visible braces undesirable, lingual braces offer a meaningful advantage.
Comfort and Adjustment Period
Because lingual braces sit against the tongue, there is typically an adjustment period during which the tongue may feel sore or irritated. Speech can also be temporarily affected, with some patients noticing a slight lisp or difficulty with certain sounds for the first few weeks. Most patients adapt within two to four weeks as the tongue adjusts to the hardware.
Traditional braces can cause soreness on the cheeks and lips, particularly early in treatment or after adjustments, but they generally do not interfere with speech in the same way.
Effectiveness
Lingual braces are effective for treating a wide range of orthodontic cases, from mild crowding to more complex misalignments, similarly to traditional braces. However, they are generally considered more technically challenging to work with, which means the experience and skill level of the orthodontist plays a particularly important role in treatment outcomes.
Cost
Lingual braces tend to be more expensive than traditional metal braces because of the custom fabrication involved and the additional technical skill required for placement and adjustment. The cost difference varies by provider and case complexity.
Hygiene
Cleaning teeth with lingual braces requires the same care as with traditional braces, including thorough brushing around each bracket and flossing with a floss threader or water flosser. Some patients find it slightly more challenging to see the brackets when brushing, since they are on the back of the teeth. Using a mirror to check your work can be helpful.
Who Is a Good Candidate for Lingual Braces?
Lingual braces are a good option for patients who want the effectiveness of fixed orthodontic treatment without visible appliances. They work well for adults and older teens who may feel self-conscious about having obvious braces in professional or social settings.
Not every case is ideal for lingual braces. Patients with very deep overbites, severe crowding, or certain jaw discrepancies may be better suited to other treatment options. People with very small teeth may also present challenges for lingual bracket placement. A consultation with an experienced orthodontist is the best way to determine whether lingual braces are appropriate for your specific case.
Lingual Braces vs Clear Aligners
Both lingual braces and clear aligners like Invisalign offer discreet orthodontic treatment, but they work differently and have different strengths. Lingual braces are fixed and work continuously, which means there is no risk of forgetting to wear them. Clear aligners are removable, which some patients prefer for eating and oral hygiene, but require discipline to wear consistently for the recommended 20 to 22 hours per day.
For complex cases that require precise tooth movements and continuous force, lingual braces may offer advantages over removable aligners. For patients who prioritize convenience and the ability to remove their appliance, Invisalign may be the better fit. Discussing both options with your orthodontist at Diamond Braces will help clarify which approach is most appropriate for your treatment goals.
What Is a Lingual Retainer?
A lingual retainer is not the same as lingual braces, though the two share a similar placement. A lingual retainer is a thin wire bonded permanently to the back surfaces of the front teeth, usually the lower front teeth, after orthodontic treatment is complete. Its purpose is to hold the teeth in their corrected position long-term. Unlike lingual braces, a lingual retainer does not move teeth. It simply keeps them in place.
Lingual retainers are a popular choice for patients who do not want to rely on a removable retainer, as there is no risk of losing or forgetting to wear them. They do require careful flossing with a threader or water flosser to maintain hygiene around the wire.
Frequently Asked Questions About Lingual Braces
What are lingual braces and how are they different from regular braces?
Lingual braces use the same bracket-and-wire system as traditional braces, but they are placed on the inside surfaces of the teeth rather than the outside. This makes them completely invisible from the front while still delivering effective orthodontic treatment.
Do lingual braces affect speech?
Many patients experience a temporary change in speech during the first few weeks after lingual braces are placed, particularly a slight lisp with certain sounds. This is because the tongue has to learn to work around the brackets on the back of the teeth. Most patients adapt fully within two to four weeks.
Are lingual braces more expensive than traditional braces?
Yes, lingual braces are generally more expensive than traditional metal braces. The higher cost reflects the custom fabrication of the brackets and the additional skill required for placement and adjustments. The exact cost varies depending on the provider and the complexity of your case.
How long does treatment with lingual braces take?
Treatment time with lingual braces is similar to that of traditional braces and depends on the complexity of the case. Most patients can expect treatment to last between 18 months and 3 years. Your orthodontist will give you a more specific estimate after your evaluation.
Can lingual braces treat all orthodontic issues?
Lingual braces are effective for a wide range of orthodontic cases, but they may not be the ideal choice for every situation. Very severe cases or those involving significant jaw discrepancies may require different approaches. An orthodontic consultation will clarify what is best for your case.
Is a lingual retainer the same as lingual braces?
No. A lingual retainer is a passive wire bonded to the back of the teeth after treatment to hold the results in place. Lingual braces are an active treatment appliance that moves teeth. Both are placed on the inner surface of the teeth, but they serve very different purposes.
