Cleaning retainers. The best way to clean your orthodontic retainer is with a cleanser designated specifically for that purpose. There are several "over-the-counter" products available, including "retainer-brite" and efferdent cleanser. Another option is simply to brush your retainer with warm water using a toothbrush. On occasion, an antibacterial hand soap is useful, but be sure to wash it well afterwards!
Carefully. Sorry, couldn't resist that very bad joke. Recommend that our patients gently brush retainers, metal and plastic with a soft toothbrush 2x/day (do not use toothpaste as it can scratch the plastic). That will get rid of the bacteria clinging to the outside of the retainers. For microbes that penetrate into the lattice structure of the plastic, use Denture Cleaner 1x/day as per pkg instructions.
