What is a "retainer"?
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.
Example
Tim 's retainer helped prevent his teeth from moving after braces.
Daily use of the retainer is crucial for lasting results.
After treatment, Alex got a clear retainer to wear discreetly.
