A Fixed Retainer (also called a “Permanent Retainer” or “Bonded Retainer”) is attached the lingual (tongue side) of your teeth with orthodontic glue. It stays in place indefinitely. This sort of retainer has its pros and cons. On one hand, other people can’t see the retainer because it’s behind your teeth. It’s permanently attached to your teeth, so you will never lose your retainer. It’s also a good choice in cases where a large relapse may occur.
On the other hand, it can bother your tongue and it takes some getting used to. It can be difficult to floss the teeth bonded to the retainer (you will need a floss threader), and it may be a little more difficult for your Dental Hygienist to clean those teeth properly.
Your Orthodontist can help you decide which type of Retainer is right for you.
