 Asad A | April 9, 2024

Wondering, "How to Clean Invisalign?" Keeping your Invisalign aligners clean is crucial for maintaining good oral hygiene and maximizing the effectiveness of your treatment. These clear aligners are made to straighten your teeth discreetly and comfortably. However, to ensure the success of your treatment and keep your aligners free from bacteria and odors, it's essential to clean them regularly.

In this comprehensive guide, we'll walk you through the steps on "How to clean your Invisalign" to help you own a beautiful smile.

Why is it Important to Clean Your Invisalign Aligners?

It is important to clean your Invisalign Aligners to help with the following:

Prevent Bacteria Build-Up:

Throughout the day, your mouth naturally collects bacteria, food particles, and plaque. If left on your Invisalign aligners, they cause bad breath problems and increase the chance of cavities and other dental problems.

Maintain Clear Appearance:

Invisalign aligners are made to be nearly invisible when worn. Regular cleaning helps keep them clear and transparent, ensuring they remain discreet during your treatment.

Prevent Stains:

Certain foods and drinks, like coffee and tomato sauce, can leave stains on your Invisalign aligners if not cleaned promptly. Proper cleaning helps prevent discoloration, keeping your aligners looking fresh and clean.

How Do You Clean Invisalign Using Proper Cleaning Methods?

You can use Invisalign crystals or make your own cleaning solution.

Invisalign Crystals:

To effectively clean your trays, opt for Invisalign crystals. These are specially designed to clean without causing any scratches or discoloration to your aligners.

Here's how to use them:

  • Fill a container with lukewarm water.
  • Empty a packet of the cleaning crystals into the water and mix until fully dissolved.
  • Place your trays into the solution and allow them to soak for approximately 15 minutes.
  • After soaking, remove the trays and thoroughly brush them before rinsing them off. Then, you can put them back in your mouth.

Hydrogen Peroxide:

At low concentrations, hydrogen peroxide is excellent for removing stains from your Invisalign aligners. Simply mix hydrogen peroxide with warm water and let your aligners soak for about thirty minutes. After soaking, brush off any remaining plaque and rinse the aligners before wearing them again.

Baking Soda:

Baking soda has gentle abrasive properties that effectively combat bacteria without harming your aligners. It's also useful for removing stuck-on food particles and plaque.

To use baking soda:

  • Add 1 tablespoon of your baking soda to 1 cup of warm water.
  • Let your Invisalign aligners soak in the water for at least thirty minutes.
  • After soaking, remove the aligners and brush them before rinsing and wearing them again.

Distilled White Vinegar:

Distilled white vinegar is a potent cleaner for your Invisalign aligners, but it's essential to use white vinegar specifically. Other types of vinegar can stain your aligners.

Here's how to use it: 

  • Combine 1 part distilled white vinegar with 3 parts water to create a solution.
  • Let your Invisalign aligners soak in the solution for fifteen minutes.
  • This allows the vinegar enough time to loosen plaque, which you can then brush away with a toothbrush.

Antibacterial Soap:

While scented soap is not suitable for cleaning your trays, clear antibacterial soap works well. Colored antibacterial soaps may stain the plastic, so it's best to avoid them.

Here's how to use it:

  • Create a solution of warm water and antibacterial soap and let the aligners soak in it.
  • You can apply the soap directly to the Invisalign aligners.
  • After cleaning, rinse the aligners thoroughly. Remember, antibacterial soap is not meant for consumption.

Important Tips to Clean Invisalign Aligners

The following are some important tips for cleaning your Invisalign Aligners.

Create a Morning Hygiene Routine

To make sure your Invisalign aligners do their job well, it's important to wear them overnight. While you're asleep, bacteria can gather on your teeth and aligners. So, it's essential to establish a morning cleaning routine.

Start your day by taking out your aligners and thoroughly brushing both your teeth and aligners. Make sure to do this again every night before you go to bed.

Also, don't forget to rinse your aligners whenever you take them out, especially during meals. This helps keep saliva and plaque buildup in check. If you're taking out your aligners to eat, brush your teeth nicely or rinse your mouth before putting them back in. This routine ensures your oral hygiene stays top-notch throughout the day.

Rinse Your Aligners After Taking Them Out

When you remove your aligners, it's important to give them a rinse. You won't be wearing your aligners all day, especially when it's time to eat and drink. Rinsing them before putting them back in is a good habit to adopt.

This helps minimize the buildup of saliva and plaque on your Invisalign. If you've taken out your aligners for a meal, consider brushing your teeth or rinsing your mouth before reinserting them.

Soak Your Aligners At Least Once a Day

Soaking your aligners at least once a day is recommended. Sometimes, simple brushing isn't enough to remove all the food particles and other debris. Soaking them can help keep your Invisalign looking its best.

You can use Invisalign cleaning crystals for this purpose. Follow the instructions given on the packaging to soak your aligners properly. After soaking, give them a good brushing to remove any stubborn plaque. Rinse your Invisalign before putting them back in after brushing your teeth.

Avoid Eating or Drinking with Your Aligners:

In contrast to metal braces, Invisalign doesn't restrict your diet. However, it's crucial not to eat while wearing your aligners. Foods and beverages with strong colors can stain them, and chewing can potentially damage them while trapping food particles. Drinking water is the only exception.

Store Your Aligners Properly:

Never leave your Invisalign exposed to the open air. This invites bacteria to accumulate and increases the risk of misplacing them, especially if placed on a table while eating. Investing in accessories like a case is essential. Always keep your aligners in case when not in use.

In Case of Emergency:

If you happen to forget your case and must leave your aligners out, ensure that you rinse them thoroughly before reinserting them. This helps maintain hygiene and prevents bacterial growth.

How should I store my Invisalign aligners when not in use?
