How long should I wear retainers after having braces?
Follow the instructions given to you by your treating dentist or orthodontist. You may need to wear a retainer day and night right after your braces are removed and, after some time, reduce this to night-time wear only. At the very least, a retainer should be worn for a year after braces are removed, at least some of the time. It is much easier to keep wearing your retainers than having to have braces again.
