How to Keep Aligners from Turning Yellow?
Simple Ways to Keep Your Trays Clear and Your Confidence High
Clear aligners are designed to be invisible, but over time, they can take on a yellow tint — and suddenly, they’re not so invisible anymore. If you’ve noticed your trays looking a little less clear lately, don’t worry — it’s more common than you think. The good news? With the right cleaning tips and habits, you can prevent yellow clear aligner trays and even reverse some of the discoloration that’s already happened. Let’s walk through 4 key pillars to keep your aligners fresh, clear, and photo-ready every day of your treatment.
🧼 Daily Cleaning is Non-Negotiable
The #1 way to stop discoloration is simple: clean your aligners consistently.
What to do:
- Rinse your trays every time you remove them
- Brush them gently with a soft toothbrush and clear, unscented liquid soap
- Avoid using toothpaste — it’s abrasive and can cause microscopic scratches that trap bacteria and stains
Tip: At NewSmile®, we recommend cleaning your aligners morning and night, just like your teeth. A clean start = a clean smile.
☕ Avoid Stain-Causing Foods & Drinks
One of the biggest culprits behind yellow clear aligner trays? What you eat and drink — especially if you forget to remove your trays beforehand.
Avoid wearing aligners while consuming:
- Coffee or tea
- Wine (especially red)
- Colored sodas and juices
- Sauces like curry, tomato, or soy
Warning: Even a quick sip with aligners in can leave long-lasting stains. Always remove your trays first — and rinse before reinserting them.
🫧 Try Safe At-Home Fixes for Discoloration
If your trays are already showing signs of yellowing, don’t panic. A few simple at-home cleaning tips can help reduce or eliminate light staining.
Try:
- Baking soda + water paste: Gently scrub with a soft brush
- White vinegar soak (1:3 vinegar to water ratio): Soak for 15-20 minutes
- Hydrogen peroxide + water soak (equal parts): For deeper disinfecting and whitening
Important: Be sure to rinse thoroughly after any soak to remove residue and avoid irritation.
🧴 Build a Routine That Sticks
Prevention is all about consistency. Set yourself up for success with a realistic, repeatable routine.
Your daily checklist:
- ✅ Brush teeth after meals
- ✅ Rinse and clean aligners before reinserting
- ✅ Soak trays weekly with approved cleaner or DIY solution
- ✅ Store trays in a clean case when not in use
