Invisalign aligners are a popular choice for straightening teeth discreetly, but keeping them clean is essential for maintaining both your oral health and the aligners’ clear appearance. Improper cleaning can lead to staining, bad breath, and bacteria build-up — all things you want to avoid while working toward your perfect smile.
In this guide, we’ll walk you through the right way to clean your Invisalign aligners daily and share common mistakes to avoid.
Why Cleanliness Matters with Invisalign
Invisalign aligners are worn for 20–22 hours a day. That’s a lot of time in your mouth — and a lot of opportunity for bacteria to thrive if the trays aren’t cleaned properly. Leftover food particles, plaque, and saliva can quickly lead to:
- Cloudy or stained trays
- Bad breath
- Bacterial growth
- Gum disease or cavities
Keeping your aligners clean helps your treatment stay on track while also protecting your overall oral health.
Daily Cleaning Routine for Invisalign Aligners
Rinse Immediately After Removal
Always rinse your aligners with lukewarm water as soon as you take them out. This helps wash away saliva and prevent dry plaque buildup.
Never use hot water—it can warp the plastic and ruin the fit of your aligners.
Brush Gently With a Soft Toothbrush
Use a soft toothbrush dedicated to cleaning your aligners. Gently brush both the inside and outside of the trays using small, circular motions. This helps dislodge debris and reduce plaque buildup.
Avoid using toothpaste, especially whitening kinds. Many toothpastes are abrasive and can scratch the clear plastic, making your aligners more visible.
Soak in a Cleaning Solution Once Daily
For a deeper clean, soak your aligners in a cleaning solution once a day. Here are a few options:
- Invisalign cleaning crystals
- Denture cleaning tablets
- A mix of equal parts white vinegar and water
- A mix of hydrogen peroxide and warm water
Soak for about 15–30 minutes, then brush and rinse thoroughly before wearing again.
What Not to Do When Cleaning Invisalign Aligners
Don’t Use Mouthwash on Aligners
Many mouthwashes contain dyes and alcohol that can stain or damage your aligners. It’s best to stick with clear, gentle cleaning products.
Don’t Eat or Drink With Aligners In
Food particles and colored drinks (like coffee or red wine) can stain the aligners and create a breeding ground for bacteria. Always remove your aligners before eating or drinking anything other than water.
Don’t Skip Brushing Before Reinserting Aligners
Putting your trays back in without brushing your teeth traps food particles and bacteria against your teeth. This can quickly lead to tooth decay and gum problems.
How to Clean Invisalign Aligners on the Go
Sometimes, you’re out and about without access to your full cleaning kit. Here’s how to manage:
- Carry a travel toothbrush and rinse your trays and teeth before putting them back in.
- Use individually packaged Invisalign cleaning towelettes or wipes.
- At the very least, rinse your aligners under water to remove surface debris until you can clean them properly.
Tips to Prevent Staining and Discoloration
- Avoid smoking or vaping while wearing aligners—nicotine can stain them yellow.
- Drink plenty of water throughout the day to help rinse your mouth and trays naturally.
- Clean your case regularly to avoid cross-contamination.
- Stick to clear or light-colored drinks when aligners are out to prevent residue on your teeth.
Cleaning Your Invisalign Case Matters, Too
Your Invisalign case also collects bacteria if not cleaned often. Wash it daily with soap and warm water. Dry it thoroughly before placing your aligners inside.
A dirty case can easily transfer bacteria back onto your clean trays.
Troubleshooting: My Aligners Smell or Look Cloudy
Cloudiness or odor usually signals that your aligners aren’t being cleaned well enough. Here’s what to do:
- Increase soaking frequency—try soaking twice a day for a few days.
- Use a stronger solution, like diluted hydrogen peroxide (equal parts water and peroxide).
- Make sure you’re brushing them and your teeth consistently.
If the problem persists, talk to your dentist or orthodontist.
Invisalign and your lifestyle go hand in hand, offering a discreet and convenient solution for achieving a confident smile without compromising your daily routine.
