The final observation and retention period of treatment normally spans approximately 12 months. During this period, appointments will be less frequent. Usually, retainers are worn every day and night for the first 6 months and then worn every night for an additional year. Each person’s requirements are different and a longer period or a different schedule may be recommended. Indefinite part time wear is necessary to maintain the desired changes that have been achieved. Just remember, orthodontic retention is a lifetime commitment to part time wear of your retainers.
