A lingual arch is used on the lower arch and sits against the inside of the lower teeth. It can be used as a space maintainer to hold the lower molars in their correct place and prevent crowding.

Removable retainers are used after active orthodontic tooth movement in order to hold teeth in place while they stabilize or to achieve limited correction of tooth alignment. For the first 4-6 months after braces, removable retainers are worn full-time, then at night only. Removable retainers are removed to eat and brush, whereas fixed retainers are glued to the inside of the teeth. The retainer that is recommended to each patient is different depending on the needs of that patient and their oral hygiene habits.
