Rinse retainers and aligners every time you take them out, brush them gently with a soft toothbrush and cool water or a mild cleaner, and soak them in a product made for appliances as directed. Avoid hot water, which can warp plastic, abrasive toothpaste, which scratches clear trays, and bleach or alcohol soaks unless your orthodontist approves. Store them in their case, never in a napkin.
Retainers and aligners collect plaque and odor just like teeth. Cleaning them wrong can cloud, warp or crack them.
Daily routine
- Rinse with cool water whenever you take them out.
- Brush gently with a soft toothbrush and mild, clear soap or a cleaner made for appliances.
- Brush your own teeth before putting them back in.
- Store in a ventilated case.

Common questions
Can I clean my retainer with toothpaste?
Many orthodontists advise against regular toothpaste on clear retainers and aligners because it scratches them. Use mild soap or a dedicated cleaner.
Can I use hot water to clean aligners?
No. Hot water can warp plastic retainers and aligners. Use cool or lukewarm water.
How often should I soak my retainer?
Follow your appliance cleaner's directions; many people soak daily or a few times a week.
Can I put my retainer in mouthwash?
Alcohol-based mouthwash can damage some plastics. Ask your orthodontist before soaking.
