How to Clean and Maintain Invisalign® Aligners

May 7, 2025

Invisalign® aligners have transformed the world of orthodontics, offering a nearly invisible and removable alternative to traditional braces. But to get the best results, it’s not just about wearing them — it’s also about keeping them clean and properly maintained. Here’s your complete guide to making sure your aligners stay clear, fresh, and effective throughout your treatment.

Why Is Cleaning Your Aligners So Important?

Because Invisalign® aligners sit snugly over your teeth for 20–22 hours a day, they’re constantly exposed to bacteria, saliva, and food particles. Without proper care, this can lead to:

Cloudy or stained aligners that make your smile look dull

Bad breath from trapped bacteria

Tooth decay or gum issues if bacteria build up under the trays

Warped or damaged aligners that no longer fit properly

By maintaining a simple daily routine, you can avoid these issues and keep your treatment on track.

Daily Cleaning Routine for Invisalign® Aligners

Follow these steps every day to keep your aligners fresh and clear:

Rinse When You Remove: Each time you take out your aligners — whether to eat, drink, or brush — rinse them under lukewarm water to wash away saliva and debris.

Brush Gently (But Not With Toothpaste): Use a soft toothbrush (separate from your regular one) and clear, unscented liquid soap to gently brush your aligners. Avoid toothpaste, as it can scratch and cloud the plastic.

Soak Once a Day: Use Invisalign® Cleaning Crystals or a denture/retainer cleaning solution to soak your aligners daily. This helps remove deeper stains and bacteria buildup.

Avoid Hot Water: Never use hot or boiling water, as it can warp the plastic and ruin the fit.

Do’s and Don’ts for Invisalign® Maintenance

Here’s a quick list to keep your aligners in top shape:

Do:

Store aligners in their case when not in use.

Brush and floss your teeth before putting aligners back in.

Stick to water when wearing aligners (remove them for anything else).

Don’t:

Eat or drink anything (besides water) while wearing aligners.

Use harsh cleaners, colored soaps, or toothpaste on the trays.

Leave aligners exposed on a napkin or surface — they can get lost or damaged.

How to Handle Stains or Odors

If your aligners start to look yellow or develop an odor despite daily cleaning, try these extra steps:

Soak in Invisalign® Cleaning Crystals or retainer cleaner for longer.

Gently brush with a mix of water and baking soda for natural odor removal.

Avoid using bleach or abrasive cleaners — these can damage the trays and are unsafe for your mouth.

If the problem persists, talk to your orthodontist or dental provider. They can check if you need replacement trays or adjustments to your care routine.
