Retention appliance care is critical after orthodontic treatment to ensure that the teeth remain in their newly aligned positions and prevent relapse. Retention appliances include removable retainers and fixed retainers, both of which help to maintain the teeth in their correct position after braces are removed.

To care for retainers, patients should regularly clean them with lukewarm water and a toothbrush, ensuring that they are free from plaque and bacteria. It's also important to wear the retainer as prescribed by the orthodontist, which may vary in frequency.

By properly caring for retention appliances, patients can maintain the results of their orthodontic treatment for many years and prevent the need for further corrections.
