How long do I need to wear retainers after braces?

Privately, a removable clear (Essix) retainer typically costs £80–£150 per arch, a Hawley retainer £150–£250 and a fixed bonded retainer £150–£350 per arch. Invisalign's Vivera retainers are usually £300–£500 for a set. A standard retainer is normally provided as part of NHS orthodontic treatment. Replacement retainers usually cost more than the originals if new impressions or a scan are required, and a lost fixed retainer needs a visit to be rebonded. Some practices include a first set of retainers in the treatment fee and charge only for replacements, so check what your quote covers.

The main types are fixed bonded retainers (a thin wire cemented behind the teeth, usually the lower front six), removable Essix retainers (a clear plastic tray similar in appearance to an aligner), removable Hawley retainers (a wire and acrylic plate), and combined approaches using both a fixed wire and a removable tray. Each has different maintenance requirements and longevity.
