Lingual braces

Usually private only

Fixed braces bonded to the inside surfaces of the teeth so they are hidden from view. Discreet, but they take some getting used to.

Also called: hidden braces, behind-the-teeth braces, inside braces

About lingual braces

Lingual braces are fixed braces fitted to the back (tongue side) of the teeth instead of the front, so they cannot usually be seen when you smile. The British Orthodontic Society describes them as one of the main types of fixed appliance.

Their big advantage is that they are practically invisible. The drawbacks the British Orthodontic Society highlights are tongue soreness and effects on speech, particularly early in treatment. They are generally provided privately.

Like other fixed braces, lingual braces are fixed in place, so they work without you having to remember to wear them, and they must be followed by retainers.

How it works

  1. Detailed orthodontic assessment with X-rays and moulds or digital scans
  2. Brackets are bonded to the inner surfaces of the teeth
  3. A wire connects the brackets and gradually moves the teeth
  4. Regular adjustment appointments
  5. Removal of the brace followed by retainers

Time, lifespan and cost

Time needed
Similar in principle to other fixed braces - often measured in months to a couple of years. Your orthodontist will estimate the time for your case.
How long it lasts
The result needs long-term retainer wear, as with any orthodontic treatment.
On the NHS?
Usually private only. Not generally available on the NHS. Adults usually pay privately for orthodontics, which is what gives them a wider choice of brace types. NHS charges

Private cost

Private orthodontic fees vary widely depending on how complex the problem is, where you live and the experience of the orthodontist, according to the British Orthodontic Society, so we do not quote a typical price. Ask for a written quotation after your consultation. (Source: British Orthodontic Society: Patient FAQs)

Pros and cons

Pros

  • Practically invisible from the front
  • Fixed in place, so there is no reliance on wearing them for enough hours
  • Can be used for many of the same problems as other fixed braces

Cons

  • Tongue soreness, especially at the start
  • Speech can be affected for a while
  • Harder to clean around because they are out of sight
  • Usually a private-only option

Aftercare

  • Take extra care cleaning the inner surfaces of your teeth; ask for a demonstration
  • Use interdental brushes daily
  • Avoid hard, sticky and chewy foods
  • Contact your orthodontist if anything breaks or is rubbing

Risks and side effects

  • Tongue irritation and ulcers while you adapt
  • Temporary speech changes
  • The same general risks as other braces: decay, gum problems and relapse without retainers

Your dentist should explain the risks that apply to you before you agree to treatment.

Problems it can help with

Twisted, tilted or uneven teeth are very common. Here is why they happen, when they matter, and the realistic ways to straighten them.

RoutineOptions

When there is not enough space for every tooth, teeth overlap and twist. Learn how crowding is assessed and the options for making room.

Common questions

Will lingual braces affect how I talk?

They can at first. The British Orthodontic Society notes speech issues and tongue soreness as the main drawbacks of lingual braces.

Will I need a retainer afterwards?

Almost certainly. The British Orthodontic Society says nearly every patient needs retainers after braces, and that you should only start treatment if you are happy to wear them to keep the result.

Who can fit braces?

Any GDC-registered dentist can provide orthodontics if they are competent to do so, but only those on the GDC's specialist list can call themselves specialist orthodontists; they have at least three years of extra training. You can check registration on the GDC register.
