Lingual braces are fixed braces bonded to the inside surface of the teeth, the side facing the tongue, so they are almost invisible from the front. For adults who want fixed braces without the visible metal, they offer a discreet option. The trade-off is a longer adjustment period for speech and comfort, and a higher cost. Research suggests lingual braces can achieve treatment results comparable to conventional braces when used appropriately.
Key takeaways
- Lingual braces attach to the tongue side of the teeth and are hidden from view.
- They can correct the same range of problems as regular (labial) braces.
- A temporary lisp is common and usually settles within one to three weeks.
- They tend to cost more than regular braces because the brackets are often custom-made.
- Clear aligners are an alternative discreet option that suits many, but not all, cases.
How lingual braces work
The mechanics are the same as ordinary braces: brackets and a wire apply gentle, steady pressure to move teeth into the planned position. The difference is placement. Instead of sitting on the front of the teeth, the brackets are bonded behind them. Because the inner surface of each tooth varies in shape, the brackets are frequently customised to the individual using digital scans, which is part of why the system costs more.
Lingual braces can address crowding, spacing, and many bite problems. For a broader look at the options for straightening teeth, see our guide to how to straighten crooked teeth.

The main trade-off: speech and comfort
Because the brackets sit where the tongue rests and moves, lingual braces affect speech more than front braces at first. Studies comparing the two consistently find more initial speech difficulty, often a lisp on certain sounds, and more tongue discomfort with lingual appliances. The reassuring part is that most people adapt within one to three weeks as the tongue learns the new contours. Reading aloud during the first week speeds up the adjustment.
Lingual braces compared with the alternatives
| Option | Visibility | Best suited to | Main trade-off |
|---|---|---|---|
| Lingual braces | Hidden behind teeth | Adults wanting fixed, invisible braces; complex cases | Speech adjustment, higher cost, harder to clean |
| Regular (labial) braces | Visible on the front | All ages and most case types | Visible metal or ceramic |
| Clear aligners | Nearly invisible, removable | Mild to moderate cases; disciplined wearers | Must be worn 20 to 22 hours a day |
If a removable option appeals more, our comparison of clear aligners versus Invisalign and our overview of what to expect with braces are worth reading alongside this.
Cleaning and care
Lingual braces are harder to see and harder to reach, which makes cleaning more demanding. Plaque that builds up around brackets can leave white spots on the teeth once the braces come off. A water flosser, interdental brushes, and a careful daily routine help. Your orthodontic team will show you how to clean around the brackets from the tongue side.
What about cost?
Lingual braces are generally the most expensive fixed-brace option in Australia because of the customised brackets and the additional skill and time involved. General-market prices vary widely by case complexity and provider. We do not list our own prices here.

Frequently asked questions
Are lingual braces really invisible?
From the front, yes, they are hidden because they sit behind the teeth. People generally cannot see them when you smile or talk.
Do lingual braces hurt more than normal braces?
They cause similar tooth-movement soreness, but more tongue irritation in the early weeks because of where they sit. This usually eases as the tongue adapts.
How long does treatment take?
Treatment time is broadly similar to regular braces and depends on the case, often somewhere between 18 months and 3 years. Your orthodontist can estimate this after assessing your teeth.
Can anyone get lingual braces?
Not always. Very small teeth or certain bite patterns can make bonding brackets to the inside surface difficult. A consultation determines whether they suit you.
The takeaway
Lingual braces give adults a fixed, fully hidden way to straighten their teeth, with results comparable to regular braces. The main costs are a short speech adjustment, more careful cleaning, and a higher price. If you want to know whether they suit your case, the team at Lumi Dental can assess your teeth and explain the options. See current consultation options on our current deals page.
