Fixed (Bonded) Retainer Cost UK

A fixed retainer is a thin wire bonded to the back surfaces of the front teeth to hold them in place after orthodontic treatment. It is also called a bonded or permanent retainer, and because it stays in the mouth continuously it does not depend on you remembering to wear anything. It is most often fitted to the lower front teeth, sometimes the upper as well, and typically costs £150 to £350 per arch in the UK. It still needs looking after: careful cleaning with floss threaders or interdental brushes, and regular dental checks to spot a loose bond early.

A fixed retainer can often be repaired rather than replaced, but it depends on what has gone wrong. If the wire is intact and has simply debonded from one tooth, a clinician can usually clean the surface and rebond that section. If the wire itself has fractured, distorted, or has failed repeatedly at the same point, a new wire is generally more reliable. The clinician will also check whether teeth have moved since the retainer failed and whether the gum and tooth surface at the site are healthy enough to bond to. Get it assessed promptly either way.

Many patients are advised to wear a removable retainer as well as a fixed one, and your clinician should set out a retention plan for your case. A bonded wire usually holds only the front teeth it is attached to, so a removable retainer covering the full arch protects the back teeth and the bite as well, and acts as a safeguard if the bonded wire fails without you noticing. The common pattern is a fixed retainer plus a removable retainer worn at night. Removable retainers are charged separately, so ask whether both are included in your quote.

A well-maintained fixed retainer can last many years, sometimes a decade or more, though wire fatigue, bond failure, or new dental work can require repair or replacement at any point. Regular dental check-ups help catch loose or failing bonds early, before teeth have a chance to shift. Fixed retainers are not considered permanent in the sense of never needing attention — ongoing monitoring is part of responsible long-term retention.

The cost of fitting a new fixed retainer, whether as part of a completed orthodontic treatment package or as a standalone procedure, typically falls within £150 to £350 per arch in the UK. Many orthodontic treatment plans include the initial fixed retainer in the overall treatment fee, so check your original quote to see whether this has already been covered before assuming it is an additional cost.

NHS orthodontic treatment sometimes includes a fixed retainer as part of the completed course, but this varies by provider and case, and removable retainers are more commonly issued. If a fixed retainer becomes loose or breaks after NHS treatment has finished, repair or replacement is generally not covered and needs to be arranged privately.
