The purpose of braces retainers is to keep the teeth in the correct position after orthodontic treatment and to prevent them from rebounding to their original position. After the braces are removed, the teeth may return to the wrong position for a certain period of time. The brace retainer can consolidate the effect of orthodontic treatment, especially for adults, because the alveolar bone is already set and the teeth are easy to be repeated after the braces are removed. It is recommended that patients who want to undergo orthodontic treatment must not be too eager to remove the braces, but listen to the professional advice of the doctor and follow the treatment steps to achieve the best results. In addition, during the orthodontic period, you need to pay special attention to oral hygiene and brush your teeth regularly to avoid tooth decay.
