How to Effectively Clean Your Invisalign Aligners
Invisalign aligners are an increasingly popular solution for discreetly correcting dental alignment issues. However, to ensure their effectiveness and maintain your oral health, it is essential to clean them regularly and correctly. Discover in this article why it is crucial to maintain your clear aligners, as well as the different methods to do so.
Why Is It Crucial to Clean Your Invisalign Aligners?
Invisalign dental trays spend many hours in your mouth each day, exposing them to a multitude of bacteria and germs. Without regular cleaning, they can quickly become a breeding ground for microbes, increasing the risk of potentially serious oral infections.
Furthermore, just like your teeth, clear aligners are susceptible to the buildup of plaque and tartar. They can also become stained from contact with coloring foods such as spices, coffee, or tea. Inadequate maintenance can therefore not only compromise your health but also alter the aesthetics of your aligners.
What Are the Different Methods for Cleaning Your Invisalign Aligners?
There are several effective techniques for keeping your clear aligners clean and hygienic throughout your orthodontic treatment.
Classic Brushing
The simplest method is to brush your aligners with a soft-bristled toothbrush, cool water, and a small amount of toothpaste. Be careful not to use hot water, which could warp the material. You can repeat this several times a day, ideally after each time you brush your teeth.
Effervescent Tablets
Widely used for cleaning removable dental appliances, these tablets disinfect, clean, and remove tartar from your aligners in one step. Simply soak them for a few minutes in a glass of water with one of these tablets. Common brands include Polident and Efferdent, with prices starting around $5-$10 per box.

Ultrasonic Cleaners
For a deep cleaning of your aligners, ultrasonic devices are an excellent option. Their principle is similar to that used for cleaning jewelry or dental prostheses: high-frequency pulses effectively eliminate bacteria. Weekly use is generally sufficient. Expect to pay between $30 and $100 for a quality device.
Invisalign Cleaning Crystals
Specially designed by the brand, these effervescent crystals eliminate odors and keep your aligners clean and hygienic. Here's how to use them:
- Empty one packet of crystals into a suitable container.
- Shake gently for 20 seconds to dissolve them well.
- Place your aligners in the container and let them soak for about 15 minutes.
- Then brush them with a soft-bristled brush and rinse thoroughly.
Invisalign crystals are sold for an average of $35-$50 for a box of 50 packets.

Homemade Recipes
You can also make your own cleaning solutions with everyday ingredients. For example, by mixing equal parts hydrogen peroxide and warm water, with a few tablespoons of baking soda. This mixture will help you get rid of yellowish stains. For a deeper tartar removal, soak your aligners for 20 to 30 minutes in a mixture of half white vinegar and half warm water. Then brush them until the tartar is completely removed.
What Oral Hygiene Should You Adopt with Invisalign Aligners?
Regularly cleaning your aligners is essential, but don't forget to maintain impeccable oral hygiene as well. This means brushing your teeth thoroughly after every meal for at least 2 minutes, making sure to remove your aligners beforehand. Complement this with dental floss or a water flosser for a perfect clean. If you can't brush your teeth, at least rinse them with plain water after eating.
