A permanent retainer is not really “permanent” – rather, it is bonded (glued) to your teeth on the backside (where your tongue touches them) and connects the front teeth so they won’t move. It can be installed or removed by your dentist.
Generally, the permanent retainer is a thin wire bonded to the back of your top and/or bottom teeth (depending on the specifics of your treatment). For this reason, another name for a permanent retainer is lingual wire. The wire is hidden from view on the back of your teeth, so the permanent retainer protects the results of your orthodontic treatment without any interruption to your new smile.
Permanent Retainers are simple to care for, but it is important to maintain oral hygiene every day to keep your teeth clean.
