How to clean aligners at home

Your invisible aligners may be cleaned in several different ways. The majority call for soaking your invisible aligners for a predetermined period in a water-based solution. Here are some of the best methods for cleaning aligners at home:

Use a UV sanitizer!

#1 – Ultrasonic cleaner

The simplest method to clean your aligners is to use the cariPRO ultrasonic cleaner. Simply put your aligners in, fill the reservoir with warm water, and turn the device on. 99% of the germs that cause odors are eliminated after two 5-minute sessions.

The cariPRO is not only an ultrasonic cleaner, but it has a built-in UV sanitizer, so it's a double dose of cleaning and sterilization. Plus, once your aligner treatment is over, you can use it to keep your retainers squeaky clean as well.

#2 – Cleaning tablets

Retainer cleaning tablets work too

Our top pick for cleaning tablets is also made by cariPRO. They can be used to clean any of your dental devices, including aligners and retainers. These tablets effectively eliminate 99.9% of bacteria and fungus and are specially formulated to target stains.

They are easy to use as well — all you have to do is dissolve a tablet in warm water, soak your aligner for five minutes, and then rinse it off and dry it.

You can also get cleaning tablets on Amazon, including brands like Efferdent or Retainer Brite — just follow the packaging instructions.

Combine equal parts warm water and hydrogen peroxide, and mix well. After adding the invisible aligners, let them soak in the solution for 30 minutes. Make sure to rinse them under warm water before putting them back in.

#4 – Soap and water

Another simple way how to clean aligners is to use soap and water. Squeeze a small amount of mild liquid soap into a cup of warm—but not hot—water, then stir to create suds. After soaking in the soapy water for 20 to 30 minutes, rinse your aligners well.

#5 – Baking soda and water

Aligners may be soaked for 60 minutes in a solution of one tablespoon baking soda to one-half cup of water. Thereafter, remove your aligners, rinse them, and put them back on your teeth.

#6 – Non-whitening toothpaste

Your aligners can easily be cleaned with some toothpaste and a toothbrush. Brush your aligners carefully using a soft toothbrush, warm water, and mild toothpaste (one made for young children or those with sensitive teeth might work well).

You should be sure you choose a milder, non-whitening toothpaste formulation. Abrasive components in whitening toothpaste have the potential to scrape your aligners, which will make it easier for bacteria and other germs to hang around.

#7 – Vinegar and water

Three parts warm water and one part white vinegar should be mixed in a cup. However, be careful that the water isn't too hot! Your aligners could be destroyed if they are submerged in hot water. After soaking your aligners in the solution for 20 minutes, rinse them in cold or warm water.

What to avoid when cleaning your aligners

We've already covered the best methods for cleaning aligners at home for good dental hygiene, but here are a few things you should stay away from, as these could damage your aligners.

  • Don’t use abrasive toothpaste: Although it might seem natural, toothpaste's abrasive qualities make it a big no-no for cleaning your aligners along with your teeth. If you’re trying this method, use a very mild toothpaste.
  • Don’t use colored mouthwash to clean aligners: Your mouth may benefit greatly from mouthwash. However, it can damage your aligners.
  • Never put aligners in the dishwasher: Dishwashers use very hot water, which will destroy or discolor your aligners.
  • Avoid other harsh chemicals: Avoid using strong chemicals like alcohol, bleach, and other substances that might permanently deform or discolor your aligners. Always choose gentler options, like those that are provided in this article.

Tips on how to keep your teeth aligners clean

#1 – Before wearing your aligners, brush and floss your teeth.

To keep your teeth aligners clean, always remove them before eating or drinking

An active strategy for maintaining the cleanliness of your aligners is to brush and floss your teeth before wearing your trays. This is a certain technique to reduce the amount of plaque, germs, and food debris that get caught in the space between your teeth, gums, and aligners.

#2 – Always take off your aligners before you eat or drink

In addition to being very unpleasant, eating or drinking while wearing aligners might harm them. For instance, food might become stuck between the trays and your teeth, scratching the plastic surfaces.

Certain meals and beverages, such as colored foods and dark liquids like coffee, red wine, fizzy sugary drinks, and even whiskey, may also stain plastic. Although you can use a straw to avoid this, it is actually best to simply remove them altogether.

How often should you clean your aligners?

Every night, you should clean your aligners regularly at the same time that you wash and floss your teeth. This aids in clearing away any accumulated food particles, trash, and germs that you unavoidably accumulate during the day.

If you accidentally drank anything opaque while wearing your Invisalign, if you put them on too soon after eating, or if they look noticeably filthy in any other way, you may clean them.

In addition to using more thorough cleaning techniques such as using an ultrasonic denture cleaner, you should rinse your aligners every time you take them off.

People typically use Invisalign or aligners from other brands to straighten their teeth, but for the aligners to work correctly, they must be cleaned frequently.

Your aligners may remain as transparent and unnoticeable as possible if you take some care of them. Since they are made to be thrown away, they often can't handle harsh cleaning methods like boiling water, abrasive brushes, and toothpaste.

Speak with your dentist if you're having trouble keeping your aligners clean. You can keep your mouth and aligners clean using the various simple methods mentioned in this article or other methods suggested by your dentist.

For a convenient and easy everyday cleaning experience, we recommend purchasing the cariPRO ultrasonic retainer cleaner.
