When it comes to making sure your retainer is clean and hygienic, here are some things to keep in mind:


  • Brush your retainer every time you brush your teeth.
  • Use cool or lukewarm water, never hot water because it can warp the plastic of the retainer.
  • Soak your retainer in a solution once a week, more often if it smells or looks dirty.
  • Use a soft-bristled toothbrush or retainer brush to scrub your retainer gently, but thoroughly.
  • Keep your retainer in a protective case when it’s not in your mouth.


  • Use hot water because it is likely to deform or alter the plastic.
  • Use toothpaste or mouthwash to clean your retainer because they can be too abrasive and may damage the plastic.
  • Put your retainer in the dishwasher because the heat can warp the retainer, and the detergents can be harmful.
  • Use sharp objects to scrape the build-up from the retainer because they can scratch the plastic making it easier for microbes to gather.

III. 7 Simple Steps to Keeping Your Retainer Fresh and Clean

Here are the steps to follow to ensure you have a clean retainer:

  1. Brush your retainer with a soft-bristled toothbrush or retainer brush using cool or lukewarm water. Make sure you gently scrub every part of the retainer.
  2. Rinse your retainer thoroughly using cool or lukewarm water to remove any residual build-up or debris.
  3. Fill a cup or bowl with cool or lukewarm water, add a tablet of retainer cleaner or a teaspoon of white vinegar to create a solution for soaking your retainer for 15-20 minutes.
  4. Use your fingers to scrub the inside and outside of the retainer gently, ensuring that all the build-up is removed, and the solution cleans every part of the retainer.
  5. Rinse the retainer thoroughly again using cool or lukewarm water.
  6. Dry your retainer with a clean towel, making sure that it is entirely dry before storing it in its protective case
