Lingual Braces: Hidden Braces Behind the Teeth

What are lingual braces?

Lingual braces are a type of fixed orthodontic appliance where the brackets and wires are bonded to the inner (lingual) surface of the teeth. Because they face the tongue rather than the cheek, they are completely hidden when you smile, talk, or eat. They work in the same way as conventional metal braces — applying constant pressure to move teeth gradually into alignment — but with no visible hardware from the outside. Each bracket is custom-made to fit the unique contour of each individual tooth.

How much do lingual braces cost in the UK?

Lingual braces are the most expensive orthodontic option in the UK due to the custom manufacturing and specialist fitting required. Treating the upper arch alone costs noticeably less than treating both arches, and the price climbs with case complexity, the bracket system used, and whether a specialist lingual orthodontist provides the treatment. Always confirm what is included: whether adjustment appointments, retainers, and emergency repairs are covered in the quoted fee. See the dedicated lingual braces cost guide for a full pricing breakdown.

Who are lingual braces suitable for?

Lingual braces can treat the same range of conditions as conventional braces — crowding, spacing, bite problems, rotations, and more. They are particularly popular with adults who need clinically complex treatment but cannot have visible fixed braces. Patients with very small teeth (limited bonding surface), a deep overbite that prevents bracket clearance, or limited tongue space due to jaw anatomy may not be suitable — a clinical assessment will determine whether lingual placement is feasible.

Lingual braces vs clear aligners

Both lingual braces and clear aligners offer discretion, but they differ significantly in how they work and what they can treat. Lingual braces are fully fixed, require no patient compliance, handle complex bite corrections well, and are truly invisible from the front. Clear aligners are removable, easier to clean around, and generally less expensive — but require consistent wear of 20 to 22 hours per day and are less effective for complex vertical or rotational movements. The right choice depends on clinical need and lifestyle.

Trade-offs to consider with lingual braces

Lingual braces have clear advantages for patients who prioritise discretion and need clinical precision. The key trade-offs are: highest cost of all brace types; a speech adjustment period of approximately 2 to 4 weeks as the tongue adapts to the brackets; more complex oral hygiene requiring careful cleaning around the inner bracket surfaces; and fewer trained providers in the UK compared to conventional or ceramic braces. Most patients find the adjustment period passes quickly and the trade-offs acceptable given the aesthetic benefit.

Retainers after lingual braces

Like all orthodontic treatment, lingual braces require retainers afterwards to maintain the result. Fixed retainers bonded behind the front teeth are a natural complement to lingual treatment — they are invisible in the same way. Removable retainers worn at night are an alternative or addition. The cost of retainers is not always included in the quoted treatment fee — always confirm upfront. Teeth have a natural tendency to drift, so long-term retainer use is recommended regardless of which brace type was used.
