One of the most important parts to remember about Invisalign aligners is that they need to be cleaned.

Although the aligners are meant to be disposed of every couple of weeks, they still require cleaning. Otherwise, you can have a very smelly or dirty set of aligners to put on every day.

Keep reading to find out the best practices for keeping your aligners clean.

Cleaning vs. rinsing Invisalign aligners

Remember, when it comes to Invisalign, there’s a difference between cleaning and rinsing. Rinsing your aligners may make them appear slightly cleaner, but you haven’t done anything to address the unseen bacteria that can build up.

The following is the basic cleansing process listed on the Invisalign website for nightly cleaning:

  • Rinse your aligners with water every night.
  • Brush your aligners with a soft-bristled toothbrush (not the one you use to brush your teeth daily) and gentle, clear liquid soap to remove any debris or food particles that have accumulated during the day.
  • Rinse thoroughly after brushing.
  • Store in a protective case whenever they aren’t in use.

Cleaning accessories

Invisalign sells a “Steraligner” product with a tray. Ingredients include rubbing alcohol and sodium bicarbonate, a natural antiseptic.

To clean your aligners, place them in the tray and soak for 3 minutes. Rinse the sterilizing solution off, and brush with warm water.

Invisalign also sells a product called “cleaning crystals” to dissolve in water and soak your aligners in.

These crystals contain cleansing agents, including sodium sulphate. These ingredients are similar to those of products used to clean retainers (but not denture cleaners) if you’re looking for a less expensive and more accessible alternative.

Is there any research on best cleaning practices?

The basic cleaning method described above is often enough to keep your aligners clean at night — but it may not be the most thorough approach.

A study published in the journal Clinical, Cosmetic, and Investigational DermatologyTrusted Source studied the pathogens on invisible aligners changed every 2 weeks for a 6-week period.

They studied three approaches:

  1. rinsing with water
  2. using effervescent tablets plus brushing
  3. brushing the aligners alone with toothpaste and a toothbrush

Researchers determined that brushing and using effervescent tablets most effectively cleaned the aligners at the study’s conclusion. They also determined that brushing was only slightly inferior to using the tablets.
