How to Clean Invisalign Aligners: The Complete Guide

Published on: June 13, 2025

Wearing Invisalign aligners is the first step, but keeping them clean is equally crucial. Meticulous care of your aligners is essential to preserve their transparency, ensure your oral health, and guarantee you successfully achieve straight teeth using Invisalign.

Why Is It Crucial to Clean Your Aligners?

Poorly maintained aligners can quickly become a breeding ground for bacteria. Saliva and food microparticles can form an invisible biofilm that leads to:

  • Plaque and tartar buildup on both aligners and teeth.
  • Persistent bad breath.
  • Yellowing of the aligners, causing them to lose their invisible appearance.
  • An increased risk of cavities and gum disease.

The Cleaning Routine: When and How?

Consistency is key. A good cleaning routine should become second nature. Before removing them to follow your food and drink rules, always rinse your aligners with cool water to prevent saliva from drying on them. You should also perform a deep clean at least twice a day, in the morning and at night.

Effective Cleaning Methods

You have several options, and you can pick the one that works best for you:

  • Brushing with a Toothbrush: Use a soft-bristled toothbrush with mild, clear liquid soap. Gently brush the inside and outside, then rinse thoroughly.
  • Using Cleaning Tablets: Denture or retainer cleaning tablets are very convenient. Soak your aligners for 10-15 minutes, then rinse them well.
  • Using an Ultrasonic Cleaner: For a professional-grade clean, an ultrasonic cleaner dislodges even the most stubborn particles.

Mistakes to Avoid with Your Aligners

To protect the integrity of your aligners, absolutely avoid:

  • Hot water, as it can warp the thermoplastic material.
  • Abrasive or whitening toothpastes, which can scratch the surface.
  • Colored mouthwashes that can permanently stain them.
  • Harsh soaps or chemicals like vinegar and baking soda.

The hygiene of your aligners goes hand-in-hand with your oral hygiene. Always brush and floss before putting your aligners back in. Adopting these habits ensures the discretion and cleanliness of your appliance and protects your smile from issues that could make an Invisalign treatment painful, leading to a smooth and effective journey.
