Orthodontic lingual retainer
A lingual retainer is a thin wire bonded behind teeth to help hold their alignment after orthodontic treatment.
The short answer
An orthodontic lingual retainer is a custom-fitted wire bonded to the back surfaces of teeth to help maintain alignment after braces or clear aligners.

How is a lingual retainer attached behind the teeth?
The wire is shaped to the inner sides of selected front teeth and secured with dental composite. It is different from a removable retainer, which is taken out for eating and cleaning, and it needs careful plaque control around the bonded areas.
How can you clean around a bonded lingual retainer?
Clean above and below the wire with a small interdental brush or floss threader, and check it with your tongue for movement or sharp edges. Keep scheduled orthodontic reviews so the bond, wire, bite, and tooth positions can be checked.
When does a loose or sharp retainer need attention?
Contact the orthodontic team if any bond loosens, the wire bends, a tooth starts moving, or the retainer irritates the tongue. Do not cut or pull the wire yourself, because an altered retainer may move teeth or injure soft tissue.
How should you maintain and repair your lingual retainer?
Ask which teeth need retention, how to clean around the wire, and what to do if one bond fails. Ask whether you also need a removable retainer and how often the fixed retainer should be inspected.
Frequently asked questions
Can a lingual retainer be removed?
A dentist or orthodontist can remove it, but a patient should not detach it at home.
Why does the wire feel rough?
Roughness may come from composite, a bent wire, or a broken bond and should be checked if it persists.
