Question 1

What is a retainer and what is it used for?

Accepted Answer

A retainer is a thin wire or transparent splint that holds teeth in their new position after active braces treatment. Without a retainer, teeth can move back to their original position (relapse).

Question 2

How long do I need to wear a retainer?

Accepted Answer

Fixed retainers (bonded retainers) are worn permanently. Removable retainers should initially be worn all day, later only at night – ideally lifelong to secure the result.

Question 3

What is the difference between a fixed and removable retainer?

Accepted Answer

A fixed retainer is a thin wire that is permanently attached behind the teeth – invisible and low-maintenance. A removable retainer (e.g., transparent splint) can be removed, but requires discipline in wearing it regularly.

Question 4

Do I also need a retainer after Invisalign?

Accepted Answer

Yes, absolutely. After any tooth correction – whether with fixed braces or Invisalign – a retainer is necessary to permanently secure the result. Without retention, there is a risk that the teeth will shift again.

Question 5

What happens if my retainer breaks or comes loose?

Accepted Answer

Contact your dentist immediately. A broken or loose retainer must be repaired or replaced promptly, as the teeth can otherwise shift again. Do not wait too long.
