How Do You Clean Invisalign Trays?

Written By Dr Erika Schoeman B.Ch.D

You should clean your Invisalign trays every day using cool or lukewarm water, a soft-bristled toothbrush and a suitable aligner-cleaning product.

Regular cleaning helps remove bacteria, saliva deposits and food debris, reducing the risk of staining, unpleasant smells and a build-up of deposits on the plastic.

How Should You Clean Invisalign Trays?

  • Start by rinsing your aligners whenever you remove them.

  • Then gently brush the inside and outside surfaces with a soft-bristled toothbrush and a suitable cleaning solution.

  • Rinse the trays thoroughly before putting them back into your mouth. Avoid hot or boiling water because excessive heat can distort the plastic and affect the fit.

  • You can also use cleaning products specifically designed for clear aligners, following the instructions supplied by the manufacturer.

What Are the Best Practices for Cleaning Invisalign Trays?

The best way to keep your aligners clean is to combine regular rinsing with daily cleaning and good oral hygiene.

Rinse your trays whenever you take them out, especially after meals. Brush your teeth before reinserting them whenever possible, as food particles and plaque trapped underneath the aligners can contribute to dental problems.

Keep your protective case clean and allow it to dry between uses. Always remove your aligners before eating or drinking anything other than plain water.

Avoid leaving your trays exposed to direct sunlight or excessive heat, and store them safely whenever you are not wearing them.

Should I Clean Invisalign Trays with Soap and Water?

Yes, you can generally clean Invisalign trays with a small amount of mild, clear, non-abrasive soap and lukewarm water.

Gently brush the trays with a soft toothbrush to remove deposits, then rinse thoroughly to remove any remaining soap.

Avoid strongly scented soaps, harsh household cleaners and abrasive products that could damage the plastic or leave an unpleasant taste.

Always follow the cleaning instructions supplied with your aligners and your dentist's advice.
