How to Sanitize & Clean Dirty Retainers & Invisaligns


Invisalign aligners are made from non-porous plastic that helps prevent bacteria from multiplying on the surface. Other types of retainers are made from a more porous material that can trap bacteria, but both types require regular cleaning to keep them sanitary. Tartar can build up on the retainer if you allow it to dry out, so soak it when it's not being used. Clean your retainer or Invisalign aligners regularly to keep them in good condition and prevent growth of bacteria.

Things You'll Need

  • Toothpaste
  • Toothbrush
  • Distilled water
  • Castile soap

Rinse the retainer with clean water, and apply a strip of toothpaste to your toothbrush.

Brush the retainer thoroughly inside and out with the toothbrush to remove tartar, bacteria and residue.

Rinse the retainer with clean water, and place it in a retainer case with distilled water to soak when you aren't using it. Add two drops of castile soap to help keep it clean, if desired, and rinse it with clean water before use.
