“I thought yellowing trays were inevitable, but a few simple habits have kept my aligners spotless and my smile confident.”
How to Keep Clear Aligners Clear & Bright
Clear aligners like NewSmile are designed to be nearly invisible, but over time, trays can develop a yellow tint if not properly cared for. Yellow aligners not only affect aesthetics but can also indicate bacterial buildup. Fortunately, with consistent habits and proper cleaning, you can maintain the clarity of your aligners throughout your treatment.
🧼 Daily Cleaning is Essential
The most important step to prevent yellowing is simple: clean your aligners every day.
- ✔ Rinse trays every time you remove them to remove saliva and debris.
- ✔ Brush gently with a soft toothbrush and clear, unscented liquid soap.
- ✔ Avoid toothpaste, which is abrasive and can cause micro-scratches that trap stains.
💡 At NewSmile®, we recommend cleaning trays morning and night, just like your teeth. A clean tray keeps your smile fresh.
☕ Avoid Stain-Causing Foods & Drinks
Many cases of yellowing come from what you eat or drink while wearing aligners. Even brief contact with colored foods or drinks can leave lasting stains.
- ✔ Coffee or tea
- ✔ Red wine or dark-colored drinks
- ✔ Colored sodas and fruit juices
- ✔ Dark sauces like curry, soy, or tomato
🚫 Always remove trays before eating or drinking anything other than water, and rinse before reinserting them.
🫧 Safe At-Home Remedies for Discoloration
If your trays are already showing mild yellowing, there are safe ways to restore brightness:
- ✔ Baking soda + water paste: Gently scrub trays with a soft brush.
- ✔ White vinegar soak (1:3 vinegar to water): Soak 15–20 minutes to remove surface stains.
- ✔ Hydrogen peroxide + water soak (1:1): Disinfect and whiten trays safely.
✨ Rinse thoroughly after any soak to remove residue and avoid irritation.
🧴 Build a Consistent Routine
Prevention is easier than fixing yellow trays. A consistent routine helps maintain clarity and hygiene:
- Brush teeth after every meal before reinserting aligners.
- Rinse and clean trays every time they are removed.
- Soak trays weekly with an approved cleaner or safe DIY solution.
- Store trays in a clean case when not in use to avoid exposure to bacteria or staining agents.
🧼 NewSmile aligners are designed to be easy to care for, keeping them clear and virtually invisible when these routines are followed.
