If you're investing in a straighter smile with clear aligners, keeping them clean is key, not only for your oral health but also for the longevity of your trays. Wondering how to clean aligners without damaging them? You're in the right place.

In this blog, we’ll walk you through the best techniques, common mistakes to avoid, and how your daily habits impact aligner hygiene.

How to Clean Aligners at Home

Cleaning your aligners at home doesn't have to be complicated. With a few simple tools and techniques, you can maintain crystal-clear trays and a healthy mouth.

Here’s a basic daily routine:

• Rinse your aligners with water every night to remove food particles
• Use a soft-bristled toothbrush to gently scrub them
• Avoid scented soaps, as they can leave a lingering taste
• Soak your aligners once a day in a cleaning solution like Invisalign cleaning crystals, effervescent tablets, or diluted hydrogen peroxide

These steps help prevent discoloration and the buildup of bacteria or plaque that can make your aligners cloudy or smelly.

How to Clean Aligners with Toothpaste

A common question we get is: Can I use toothpaste to clean my aligners?

Technically yes, but proceed with caution. Many toothpastes contain abrasive particles that can scratch your aligners, making them more prone to trapping food debris and bacteria.

If you choose this method:

• Use a non-abrasive, gel-based toothpaste
• Gently brush with a soft toothbrush
• Rinse thoroughly with warm water (not hot!)

For best results, avoid whitening pastes or baking soda when using toothpaste, as they may degrade the plastic.

How to Clean Aligners with Baking Soda

Baking soda is a gentle, natural cleanser that can be effective for occasional deep cleaning. Here’s how:

1. Mix one tablespoon of baking soda with half a cup of warm water
2. Soak your aligners for 20–30 minutes
3. Rinse thoroughly before reinserting them

This method helps neutralize odors and can gently lift surface stains.

Best Way to Clean Invisalign Aligners

If you're using Invisalign, you're probably looking for the safest and most effective way to clean your trays.

The best way to clean Invisalign aligners includes:

• Using Invisalign’s own cleaning crystals
• Daily brushing and rinsing
• Soaking in denture cleaner or hydrogen peroxide
• Avoiding hot water, which can warp the plastic

Avoid placing your aligners in napkins or exposed containers when eating, store your aligners in their protective case to prevent contamination.

Other Cleaning Solutions to Try

• Hydrogen Peroxide: Dilute with water and soak for 20 minutes
• Antibacterial soap: Clear, scent-free liquid works best
• Vinegar: Mix equal parts vinegar and water for a 15-minute soak
• Aligner cleaner tablets: Convenient and travel-friendly

Each solution has pros and cons, but all can be effective when used consistently.

How to Clean Your Aligners Without Staining Them

Clear aligners can stain over time if exposed to:

• Colored beverages like coffee, wine, or soda
• Colored mouthwash
• Poor cleaning habits

To avoid stains:

• Always brush and floss your teeth before reinserting aligners
• Avoid smoking or vaping with aligners on
• Rinse immediately after eating or drinking anything other than water

If your trays begin to stain your aligners, ask your provider whether replacement is needed or if professional cleaning can help.
