Before You Start
Before cleaning, remove the retainer with clean hands and rinse under lukewarm water to remove loose food particles. Do not use hot water, as heat can warp plastic. Always read the device and tablet instructions before use. Avoid harsh chemicals, bleaching agents, and abrasive cleaners, which can scratch or weaken the plastic. Plan cleaning sessions a couple of times per week, or as recommended by your dentist.
Step-By-Step: How To Clean Plastic Retainers
- Rinse: Rinse the retainer under lukewarm running water to dislodge loose debris.
- Soak: Place the retainer in a dedicated cleaning solution or tablet as directed. If using tablets, drop one tablet into a glass of water and submerge the retainer fully.
- Gentle cleaning: Let the retainer soak for the recommended time, usually 5–15 minutes, then use a soft bristle brush to gently scrub all surfaces, including nooks and edges.
- Rinse again: Thoroughly rinse under lukewarm water to remove all cleaning agents.
- Inspect: Check for residues or cloudy areas. If needed, repeat the soak and brush steps.
- Dry: Gently shake off excess water and place the retainer in its cleaning case with the lid open to air-dry, or use a clean cloth.
- Deep cleaning (optional): For stubborn buildup, use an ultrasonic cleaner for dental retainers according to the device instructions, ensuring the item is fully submerged and the cleaning cycle completes.
- Reinsert: After drying, reinsert the retainer or store it in the provided case with proper ventilation to prevent odor buildup.
- Maintenance rhythm: Repeat cleaning as part of a regular routine—2–3 times weekly, or more often if you notice buildup.
- Alternate method: If you do not have a tablet, a mild soap and water solution can serve for quick cleanings, but avoid household cleaners that may corrode or affect the plastic.
- Odor control: If odor persists, consider a longer soak with a specialized cleaner and verify that the storage case stays dry between uses.
