Is it permissible to wear retainers while fasting?

In the Name of Allah, the Most Gracious, the Most Merciful.

As-salāmu ‘alaykumwa-rahmatullāhiwa-barakātuh.

Orthodontic retainers are custom-made devices, made usually of wires or clear plastic that holds the teeth in position after surgery or any method of realigning the teeth. They are most often used before or after dental braces to hold teeth in position while assisting the adjustment of the surrounding gums to changes in the bone.[1]

It is permissible for one to wear orthodontic retainers while fasting.

And Allah Ta’āla Knows Best
