Overview
Teeth tend to drift after orthodontic treatment, so retainers keep them in their new position. There are removable types you take out, and fixed types bonded behind the teeth.
Retainers usually need to be worn long term, often for life in some form. How often you wear a removable retainer may reduce over time, as your dentist advises.
