The “Fresh Smile” Fast Facts
Rinse: Every single time you take your aligners out.
Brush: Use a soft-bristled brush and clear, unscented antibacterial soap (never toothpaste!).
Soak: Daily for 15-20 minutes using Invisalign Cleaning Crystals or a professional-grade ultrasonic pod.
The “Golden Rule”: If your aligners are not in your face, they should be in their case.
Why Cleaning Your Aligners Matters
At Blue Ridge Orthodontics, we are a Top 1% Invisalign Provider. We know that the secret to a successful treatment isn’t just wearing the trays for 22 hours a day—it’s keeping them invisible. Without proper care, your aligners can trap bacteria against your teeth, leading to bad breath, cloudy trays, and even tooth decay.
If you are just starting your journey, be sure to check out our guide on 20 Things to Know Before Getting Braces or Invisalign to set yourself up for success.
Your Daily Invisalign Cleaning Routine
Maintaining clear trays shouldn’t be a chore. Follow this simple table to keep your smile sparkling from morning to night.
Daily Maintenance Checklist
| Time of Day | Action | Why It Matters |
| Morning | Brush trays & teeth immediately. | Removes “sleep bacteria” and plaque buildup from the night. |
| Every Meal | Rinse trays with lukewarm water. | Prevents saliva from drying into a film (biofilm) on the plastic. |
| Evening | Deep soak for 15 minutes. | Disinfects the trays and removes any micro-stains from the day. |
| Bedtime | Brush & floss before putting trays in. | Trapping food under aligners is the #1 cause of side effects like decalcification. |
Deep Cleaning: The “Pro” Level Care
For a truly crystal-clear look, “just rinsing” isn’t enough. At our Asheville, Brevard, and Hendersonville clinics, we recommend the following deep-cleaning methods:
1. Ultrasonic Cleaning Pods
Modern technology has changed the game. Ultrasonic cleaners use high-frequency sound waves to create millions of “micro-bubbles” that scrub away plaque in areas a toothbrush can’t reach.
Note: Many BRO patients now receive an ultrasonic pod as part of their comprehensive care!
2. Invisalign Cleaning Crystals
These are specifically formulated to remove plaque and kill bacteria without damaging the medical-grade plastic.
Pro Tip: If you run out of crystals, a 50/50 mix of white vinegar and lukewarm water is a great DIY alternative (just rinse well afterward to remove the smell!).
The “Never” List: Common Cleaning Mistakes
Avoid these four common errors to ensure your treatment stays on track and your trays stay clear.
Warning: Avoid These “Aligner Killers”
Hot Water: Extremely hot water will warp the plastic, rendering the tray useless and requiring a costly replacement.
Toothpaste: Most toothpastes contain abrasives (like silica) that create microscopic scratches in the plastic, making them look cloudy and “dirty.”
Mouthwash: Colored mouthwashes (especially blue or green) can permanently stain your clear trays.
Scented Soaps: Using “Fresh Spring” hand soap will make your aligners—and your next meal—taste like perfume. Stick to clear, unscented soap.
Impressions Aligners vs. Invisalign
Did you know that BRO offers Impressions Aligners? This at-home treatment uses the same high-quality materials as Invisalign. The cleaning rules remain identical: whether you are using Invisalign or Impressions, hygiene is the key to your #ImpressionSmile.
Frequently Asked Questions (FAQ)
Q: Can I drink coffee with my aligners in if I clean them immediately after?
A: No. Coffee is both hot (risking warping) and highly acidic/pigmented (risking stains). Always remove your trays for anything other than plain water.
Q: My trays are starting to smell. What should I do?
A: This is usually due to “Retainer Fatigue” or bacterial buildup. Try a 20-minute soak in a professional cleaner. If they still smell, or if you notice cracks, it might be time for a retainer replacement.
Q: Can I use a denture cleaner?
A: Generally, yes. Efferdent or similar products are safe for occasional use, but they can be slightly more abrasive than Invisalign-specific crystals.
