How to Clean Clear Aligners for a Healthy, Sparkling Smile

March 18, 2025

Clear aligners like Invisalign have revolutionized orthodontics, offering a comfortable, discreet, and effective way to straighten teeth. However, keeping your aligners clean and free from bacteria is essential to prevent staining, bad breath, and oral health issues.

At Innovative Dental & Orthodontics, we educate our patients on the best cleaning practices to ensure their aligners stay hygienic and invisible throughout treatment. This guide covers everything you need to know about how to clean clear aligners, what to avoid, and expert maintenance tips.

Why Cleaning Your Clear Aligners is Essential

  • Prevents Bacteria Buildup – Aligners can trap plaque and bacteria, leading to gum disease or bad breath.
  • Maintains Transparency – Stains and cloudiness can make aligners more noticeable over time.
  • Extends Aligner Lifespan – Proper cleaning prevents warping or degradation of aligner material.
  • Promotes Oral Health – Dirty aligners contribute to tooth decay and gum inflammation.

A simple cleaning routine ensures your aligners stay fresh and effective!

Step-by-Step Guide: How to Clean Clear Aligners

1. Rinse Aligners Every Time You Remove Them

Rinse your aligners with lukewarm water every time you remove them to wash away saliva and plaque buildup. Avoid using hot water, as excessive heat can warp the plastic and affect the fit. Regular rinsing throughout the day helps prevent bacteria accumulation, keeping your aligners clean and your treatment on track.

2. Brush Your Aligners Gently

To keep your aligners clean and clear, use a soft-bristled toothbrush with clear, unscented soap to gently brush both the inside and outside surfaces. Avoid using colored toothpaste, as it can be too abrasive and may scratch or discolor the aligners. Regular brushing helps remove food particles, plaque, and bacteria, ensuring your aligners remain fresh and odor-free throughout your treatment.

3. Soak Aligners for a Deep Clean

To keep your aligners clean and free from bacteria buildup, soak them in an aligner cleaning solution like Invisalign Cleaning Crystals or Retainer Brite for 10-15 minutes. If you prefer a natural alternative, a mixture of white vinegar and water (1:3 ratio) or hydrogen peroxide and water (1:1 ratio) can effectively clean your aligners. Regular soaking helps remove stubborn stains, eliminate bacteria, and maintain the clarity of your aligners, ensuring a fresh and hygienic fit throughout your treatment.

4. Brush and Floss Before Reinserting Aligners

After every meal, it’s essential to brush your teeth and floss before reinserting your aligners. Food particles trapped between your teeth and aligners can lead to plaque buildup, increasing the risk of cavities and gum issues. Maintaining good oral hygiene not only protects your teeth but also keeps your aligners fresh and odor-free, ensuring a clean and comfortable fit throughout your treatment.

5. Store Aligners Properly

Always store your aligners in their protective case when not in use to prevent loss or contamination. Avoid wrapping them in napkins or placing them in pockets, as this increases the risk of misplacing or damaging them. Keeping aligners in their designated case ensures they remain clean, free from bacteria, and protected from accidental damage, ultimately prolonging their effectiveness throughout your treatment.

Common Mistakes to Avoid When Cleaning Aligners

  • Using Toothpaste – Many toothpastes contain abrasive particles that can scratch aligners.
  • Soaking in Mouthwash – Alcohol and dyes in mouthwash can discolor and weaken aligners.
  • Boiling Water or Dishwashers – High temperatures warp and ruin the shape of aligners.
  • Skipping Cleaning – Not cleaning aligners leads to odors, staining, and bacteria buildup.
  • Leaving Aligners Exposed – Leaving them out in the open attracts germs and dirt.

Proper care ensures aligners remain clear, odor-free, and effective!
