Retainers can be fixed or removable and they're used to retain the straighteness of your teeth
During your final visit, your dentist will give you the necessary instructions on how you should wear your retainers.
As there are fixed and removable options, it's best to take the advice of your dentist about which type is most suitable for you.
Retainers should be worn daily, but the length of time varies, so it could be that you wear them until an appropriate review date with your dentist if using the fixed option, while removable retainers might be worn at night only.
