a device used to maintain the position of teeth after braces are removed
A retainer is a dental device used to keep teeth in their new position after orthodontic treatment, like braces. It is usually made of plastic or metal and fits closely over the teeth. Retainers help prevent teeth from shifting back to their original position and maintain the results achieved through orthodontic work.
