Cleaning tools for your retainer.
Cleaning your retainer should be done right.

Have you noticed the presence of white spots on your orthodontic retainers? Even when you brush your teeth regularly, it seems as though they just won’t come off! 

Those white spots are actually calcium left behind by your saliva and can be deposited on your retainers over time. Note also that your retainers, like your teeth, can experience a build-up of plaque and tartar. Leave the buildup there for long and you increase your own risk of developing plaque, decay, and other dental issues.

If you are diligent enough to brush your teeth and to clean your retainer regularly, then these white deposits will be a minor problem. Keep reading to find out the most effective ways to maintain your retainers.

Retainer cleaning frequency

Cleaning your retainer is something that should be done regularly. But how often should you do it? Experts suggest that you should clean your retainer once a day before you insert it into your mouth. Whenever you brush your teeth, use a soft-bristled brush to eliminate any buildup. 

But if you want a more thorough cleaning, you can soak them in special cleaners at least once a week or as often as needed. How do you know it’s time to clean your retainers? Look out for the following signs:

  • If the retainer tastes or smells bad
  • If you see a film on the retainer
  • If it feels uncomfortable
  • If it has been over a week since you last cleaned your retainer
  • If there are white spots or deposits on the retainers
  • If the retainer is cloudy in appearance
  • If you notice that the retainer starts to crack or break

On top of these signs, you can also look into cleaning your retainers when you have developed oral health problems. Cavities, tooth sensitivity, and other mouth issues can be major signs that a retainer needs cleaning.

Caring for different types of retainer

Depending on the type of retainer you have, the cleaning method you use may vary. Most methods involve removing it to brush it and some kind of soaking. Here are some general guidelines:

How to clean plastic retainers

The cleaning methods outlined above will work for plastic retainers. Using a mild soap is recommended. Be careful and gentle when brushing your trays. Take your time because rushing can lead to breakage. It is also advisable to use a soft-bristled brush when removing dirt and buildup off of plastic retainers.

How to clean clear retainers

Do not use toothpaste, mouthwash, or other cleaning agents that may discolor your clear retainers. Soaking it overnight in cool water is a better idea.

Natural methods for cleaning retainers

Cleaning your retainers does not necessarily require you to purchase dental cleaning products. While you can find plenty of them sold on the market today, there are a wide variety of natural cleaning solutions. These are some of the best options available to clean your retainer:

Wash with water

The use of water to clean your retainer is one of the most basic natural solutions there is. Doing this at the same time as when you brush your teeth will discourage the overgrowth of bacteria.


The use of toothpaste is also another cost-effective way to clean your retainer. When you brush your teeth, you can also brush your retainer along with it. Make sure you use a soft-bristled brush, though, so you won’t damage the retainer. 

It is also best that you use non-whitening toothpaste when brushing. Rinse it thoroughly once you are done.

Baking soda

Baking soda is one of the most versatile items to have in your home. Not only does it whiten your teeth, but it is also a great product to use to clean your retainer. Baking soda is an all-natural disinfectant so it is great for keeping your devices and mouth clean. 

As a bonus, it can whiten retainers that have turned yellowish in appearance. By soaking your trays in a baking soda and water solution, you can get rid of bacteria and maintain the pH balance in your mouth. 

Tips for cleaning with baking soda

Follow these steps to clean your retainer with baking soda:

  • Mix equal amounts of water with baking soda to form a paste. The paste should be thick enough in consistency so that it will stick to your retainer.
  • Scrub the paste mixture directly onto the retainer. Use a soft toothbrush and apply the paste onto the retainer as you would when brushing your teeth. 
  • Remove any residue by rinsing thoroughly with water. 


Aside from baking soda, vinegar is another highly recommended natural product to use for keeping your retainer clean. White vinegar is a natural disinfectant. So, how do you clean retainers with vinegar?

By soaking your retainers in a vinegar and water solution, you can eliminate odors and bacteria from your device. 

To use this cleaning solution, combine equal parts of water and vinegar in a dish. Soak your retainer in that solution for at least 20 minutes. This is a great way to remove mineral or calcium deposits on your retainer. 

Castile soap

Castile soap is an effective cleaning product that is not as harsh as other cleaning chemicals. Therefore, it is a good option for cleaning retainers at home. You can make your own castile soap solution by mixing coconut oil with olive oil. 

If not, you can find one in a store near you. To use, add a small amount of the castile soap into warm water. Dip the retainer into that mixture and then use a toothbrush to scrub it clean. 

Repeat the process as often as necessary. But make sure to rinse your retainer with cool water before putting it back into your mouth. 

Mouthwash: Is it safe to soak your retainers in it?

Using mouthwash as a cleaning solution for retainers should be done with caution. A quick mouthwash soak is a great way to kill bacteria buildup in your retainer. It can also give it a fresh smell.

However, you need to be cautious about alcohol-based mouthwashes. Make sure to limit the frequency of use as it can damage your device, especially if it is made of plastic.

When using a mouthwash soak, make sure to combine equal parts of the mouthwash rinse with lukewarm water. Soak it for a few minutes and rinse thoroughly. 

Does boiling your retainer do anything?

Don't use boiling water for retainer cleaning purposes. Exposing the retainer to high heat can damage it. In fact, hot water should be avoided as well.

You can also find a variety of retainer cleaning products on the market. Whichever you choose, it is important that you use them regularly. This will ensure that the retainer does its job of maintaining the correct alignment of your teeth without damaging your oral health. 


Can you boil your retainer?

You cannot boil your retainer! In fact, keep it out of hot water of any kind.

How do I get the white stuff off my retainer?

The presence of ‘white stuff' on your retainer is caused by calcium buildup from your saliva. The best way to get this off is to lean your retainer regularly with one of the solutions above.

How often should you clean your retainer?

You should clean your retainer at least once a day, and the best time is before you insert it into your mouth.
