Keeping your Invisalign retainers clean is essential for good oral hygiene and the success of your orthodontic treatment. Proper cleaning helps prevent germs, plaque, and bad smells from building up. Here’s a simple guide from Family Dental in St. Albert to help you keep your retainers fresh and clean.

Best Ways to Clean Invisalign

Cleaning your aligners regularly ensures they stay clear and free of bacteria. Here are some effective ways to clean them:

  1. Rinse Your Aligners

    Rinse your aligners with lukewarm water after removing them. This helps wash away saliva, food particles, and dirt. You can also use a soft toothbrush to gently clean them.

  2. Use Invisalign Cleaning Crystals

    Invisalign cleaning crystals are designed to kill germs, remove buildup, and eliminate stains and odors without damaging your aligners. Dissolve the crystals in lukewarm water and soak your aligners as directed on the package.

  3. Soak in Dish Soap or Cleaning Tablets

    Soak your aligners in lukewarm water with mild dish soap or non-abrasive cleaning tablets. Avoid scrubbing and steer clear of products with alcohol.

  4. Dawn Dish Soap

    If needed, use a small amount of Dawn dish soap on your fingers to gently clean the aligners. Rinse thoroughly after cleaning.

  5. Baking Soda Paste

    To tackle stains or odors, make a paste of baking soda and water. Gently brush it onto the aligners and rinse them well.

Things to Avoid When Cleaning Invisalign

  • Avoid Toothpaste

    Toothpaste can be abrasive and scratch your aligners, making them more likely to trap bacteria and become cloudy.

  • Skip Mouthwash with Alcohol

    Mouthwashes containing alcohol can damage your aligners, causing discoloration or weakening the plastic.

  • Don’t Use Hot Water

    Hot water can warp your aligners, affecting their fit and effectiveness. Always use lukewarm water.

  • Avoid Colored or Scented Cleaners

    These can stain your aligners or leave an unpleasant taste. Stick to clear, odorless cleaning solutions.

How Often Should You Clean Your Invisalign?

Clean your aligners at least twice a day—once in the morning and once before bed. This routine keeps them free of bacteria and helps maintain your oral health.
