Do I have to clean my retainer?
I f you wear a retainer, you might be wondering how to care for it.
Your retainer sits inside your mouth and against your teeth, so it quickly accumulates bacteria, plaque, and tartar.

This is because teeth aren’t set in a rigid environment. Even after they’ve been corrected by braces and moved into a better position, they can shift over time.
Retainers help the muscles and tissues in your mouth hold teeth in their new placement. Some people may even need to wear their retainers at night indefinitely to keep teeth in place.
