How to Clean Your Clear Aligners: Simple Tips for Freshness and Hygiene

Clear aligners like Invisalign are a game-changer in orthodontics: they’re discreet, comfortable, and effective. But there’s one responsibility that comes with them—keeping them clean. Aligners sit in your mouth for up to 22 hours a day, so keeping them clean is essential for both your oral hygiene and the effectiveness of your treatment. Let’s walk through how to clean your aligners properly, what to avoid, and which methods offer the best results—without breaking the bank.

Why Cleaning Your Aligners Matters

Neglecting to clean your aligners can lead to:

  • Bad breath and unpleasant taste

  • Bacterial buildup and plaque

  • Staining or cloudiness on your trays

  • Increased risk of cavities or gum issues

  • Shortened lifespan of your aligners

In short: dirty aligners don’t just look bad—they can affect your health and your smile.

The Easiest Way to Clean Aligners: Toothbrush & Toothpaste

The most accessible and affordable method is also the most convenient:

✅ Brush your aligners every time you remove them

 using:

  • Your regular toothbrush (soft-bristled preferred)

  • Your regular toothpaste (non-abrasive is best)

  • Lukewarm water (never hot—it can warp the plastic)

This removes saliva, plaque, and food particles before they can harden or cause odor.

Pro Tip:

Always rinse your aligners thoroughly before reinserting them, especially after eating or drinking anything other than water.

For a Deeper Clean: Invisalign Cleaning Crystals

If you want a more thorough clean, Invisalign cleaning crystals are a professional-grade option. These dissolvable crystals remove:

  • Bacteria

  • Stains

  • Odors

  • Mineral buildup

How to use:

  1. Fill a glass or cleaning tray with lukewarm water

  2. Add one packet of cleaning crystals

  3. Soak your aligners for 15–30 minutes

  4. Rinse thoroughly and brush if needed before reinserting

Keep in mind:

  • These crystals are highly effective but come at an extra cost

  • They’re great for weekly or biweekly deep cleans

  • They help preserve clarity and hygiene over time

Other Optional Cleaning Methods

  • Antibacterial soap & water: Gentle and effective if you avoid harsh chemicals

  • Ultrasonic cleaners: A hands-free gadget that vibrates plaque off aligners

  • Hydrogen peroxide & water (1:1 ratio): Occasional soak to kill bacteria—just rinse thoroughly

  • White vinegar & water (1:1 ratio): A natural soak to remove mineral buildup—follow with brushing

Avoid:

  • ❌ Boiling water or hot tea (warps aligners)

  • ❌ Mouthwash with alcohol (can discolor or damage plastic)

  • ❌ Abrasive toothpaste (can scratch the surface)

When Should You Clean Your Aligners?

Every time you remove them

Before putting them back in

At least twice daily with your regular brushing

Weekly deep clean for long-term freshness

Remember, clean aligners = a clean mouth = better results.
