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:
Fill a glass or cleaning tray with lukewarm water
Add one packet of cleaning crystals
Soak your aligners for 15–30 minutes
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.
