How to Clean Invisalign

Introduction

Invisalign aligners can quickly build up plaque, bacteria, and cloudy residue if they aren’t cleaned properly. Keeping them clear not only looks better but also helps protect your oral health and prevents unpleasant odors. With the right cleaning routine, you can keep your trays fresh, stain-free, and comfortable to wear.

What You'll Need

• Soft toothbrush

• Clear, mild liquid soap

• Lukewarm water

• Invisalign cleaning crystals or denture tablets (optional)

• Small bowl

• Non-abrasive cloth or paper towel

Steps

Remove your Invisalign trays and rinse them under lukewarm water to wash away saliva and loose debris.
Apply a small amount of clear, gentle soap to a soft toothbrush and gently brush the inside and outside of the aligners.
Brush thoroughly around edges, grooves, and ridges where buildup tends to accumulate.
Rinse the trays again under lukewarm water until all soap is removed.
Pat dry with a soft cloth or allow the aligners to air-dry.
Before inserting them, brush and rinse your teeth to prevent new residue from transferring onto the aligners.

Alternative Methods

• Soak the aligners in Invisalign cleaning crystals according to the package instructions for deep cleaning.

• Use a denture-cleaning tablet in a bowl of lukewarm water for 10–15 minutes, then rinse thoroughly.

• Use a 50/50 mixture of white vinegar and lukewarm water; soak for 15 minutes, brush gently, and rinse well.

• Use a hydrogen peroxide and water solution (equal parts) for occasional stain removal.

What NOT to Do

• Do not use hot water, as it can warp the aligners.

• Do not use colored soaps, which may stain or cloud the trays.

• Do not use toothpaste; it is abrasive and can scratch the plastic.

• Do not soak aligners in mouthwash with dyes, which can discolor them.

• Do not use harsh chemicals like bleach or alcohol-based cleaners.

FAQs

How often should I clean my Invisalign trays?

Clean them every time you remove them—typically twice daily plus quick rinses throughout the day.

Why are my Invisalign trays turning cloudy?

Cloudiness is caused by plaque buildup or abrasive cleaning. Gentle, consistent cleaning helps keep them clear.

Can I use toothpaste to clean Invisalign?

No. Toothpaste is abrasive and can scratch the plastic, making aligners more prone to staining.

Is it safe to soak Invisalign in vinegar?

Yes, as long as it is diluted and thoroughly rinsed afterward.

What if my aligners still smell after cleaning?

Soak them in cleaning crystals or a denture tablet for a deeper clean, and ensure you’re brushing your teeth before reinserting them.
