Service life of retainer

Generally, it is about two years, and it varies from person to person. Some patients need to keep it for a shorter time, while for some cases that are very easy to relapse, such as severe tooth torsion and tooth space, it needs a longer retention period, or even lifelong retention Generally speaking, it takes at least one year for the tissues around the teeth to recover and stabilize. The first three months after treatment are particularly prone to relapse In the first year after the removal of the appliance, the holder should be worn carefully during the day and night. After that, the holder was worn at night for 6 months. If you feel easy to wear, you can further reduce the wearing time of the holder: one night every other day, one night a week until you completely stop wearing it.
