Can I Use Listerine to Clean My Invisalign?

It's not recommended to use Listerine to clean your Invisalign, as it can stain and damage the aligners. Instead, use a purple persulfate-free retainer cleaner. This cleaner is gentle and effective, ensuring your aligners stay clear and hygienic without harsh chemicals.

Why Cleaning Invisalign Aligners Is Important

Prevents Bacterial Build-Up

Regular cleaning of your Invisalign aligners prevents the accumulation of bacteria, which can lead to bad breath, cavities, and gum disease.

Maintains Clear Appearance

Keeping your aligners clean helps them stay clear and less noticeable, maintaining the aesthetic advantage of Invisalign over traditional braces.

Ensures Effective Treatment

Clean aligners fit better and work more effectively in moving your teeth into the desired position.

The Role of Listerine in Oral Hygiene

Listerine is a popular mouthwash known for its antibacterial properties and ability to freshen breath. It contains active ingredients like essential oils and alcohol, which can kill germs and reduce plaque. However, its effectiveness and suitability for cleaning Invisalign aligners are debatable.

Pros of Using Listerine for Invisalign

Antibacterial Properties

Listerine’s antibacterial components can help in reducing the bacteria on your aligners, ensuring a cleaner surface that comes into contact with your teeth.


Using Listerine is convenient, especially if you already have it as part of your oral hygiene routine. It’s easy to incorporate aligner cleaning into your daily regimen.

Freshens Breath

Using Listerine can leave a fresh taste in your mouth, which can be beneficial since aligners can sometimes trap food particles and bacteria that cause bad breath.

Cons of Using Listerine for Invisalign

Alcohol Content

Many Listerine products contain alcohol, which can be too harsh for the plastic material of Invisalign aligners. Prolonged exposure to alcohol can degrade the plastic, leading to discoloration and weakening of the aligners.

Potential Staining

Colored mouthwashes like some varieties of Listerine can stain the aligners over time, reducing their transparency and aesthetic appeal.

Residue Build-Up

Listerine can leave a residue on the aligners, which may not be thoroughly rinsed away with water. This residue can interfere with the aligners' fit and effectiveness.

Additional Tips for Invisalign Users

Maintain Regular Oral Hygiene

Brush and floss your teeth thoroughly before putting your aligners back in. This prevents trapping food particles and bacteria between your teeth and the aligners.

Stay Hydrated

Drinking plenty of water helps keep your mouth clean and can prevent aligners from developing an odor.

Avoid Colored and Sugary Beverages

When wearing aligners, avoid consuming colored and sugary drinks that can stain and promote bacterial growth on the aligners.

Regular Dental Check-Ups

Continue with regular dental check-ups to ensure your teeth and gums remain healthy throughout your Invisalign treatment.


Maintaining clean Invisalign aligners is crucial for effective treatment and oral health. While Listerine offers antibacterial benefits, it is not the best option for cleaning aligners due to potential damage and discoloration. Opt for Invisalign-specific cleaning solutions, mild soap, or hydrogen peroxide to keep your aligners in top condition. Following proper cleaning protocols will ensure your aligners remain clear, hygienic, and effective throughout your treatment journey.
