Plastic retainers help keep your teeth straight after braces, but they need proper cleaning to stay germ-free. Over time, retainers can collect bacteria that might make you sick if you don't clean them well. According to Dr. Gary Cash, a dentist based in Austin, Texas, "Just like your teeth need daily cleaning, retainers need to be cleaned every day to prevent bacteria buildup and bad breath." We'll walk you through simple ways to keep your retainer clean and make it last longer, from basic daily cleaning to deeper cleaning methods that kill germs. These easy steps will help keep both your retainer and your mouth healthy and fresh.
Keep Retainers Bacteria-Free
While maintaining a clean retainer is essential for oral health, keeping it bacteria-free requires daily attention and proper cleaning techniques.
To keep good oral hygiene, we recommend brushing your retainer with a soft-bristled toothbrush and mild dish soap each day. Rinse with cool water, and don't forget to clean your retainer case regularly to prevent harmful bacteria from growing.

Things to Avoid When Cleaning a Plastic Retainer
Proper care and maintenance of your plastic retainer is vital for maintaining its shape, clarity, and effectiveness over time.
While keeping your retainer clean is essential for oral hygiene, using incorrect cleaning methods can severely damage or completely ruin this expensive orthodontic device.
