When wearing any alignment system, germs and bacteria can easily accumulate on the surfaces, especially on the undersides where the devices rest on the gums or teeth. That’s why cleaning your teeth aligners is something that should be done daily.

With that in mind, you are probably wondering how to clean a retainer properly. Well, there are many different ways to clean them, and here are some great ideas that help keep your smile looking great!

Best Way to Clean Retainers

There are several products and ways to clean your retainers, but we have selected the best ones. Here’s all the info you need before deciding which one to choose:

The first and most obvious way to clean your retainers is by using a retainer cleaners. There are many brands of clear braces cleaners available, even aligners’ brands that sell their own cleaners (Invisalign, byte, etc.). The most common retainer cleaners are tablets that you have to mix with water and then soak the aligner there, however, there are also special toothbrushes or cleaning foams available if you don’t like the results given by the tablets.

Although the products may vary in form (tablet, foam, or toothbrushes), all of them are very easy to use and with few or any cons as they are products specifically and optimally designed to clean retainers.

But, you are probably wondering how to clean plastic retainers with these products?

Tablets

You start by filling a cup with lukewarm water then drop a tablet in. After that, you place the trays in the glass or cup and watch the bubbly fizzing action do its job. Since the soaking times vary, you need to read the manufacturer’s directions to ensure you use the recommended steps correctly. Some claim that you can soak them overnight if needed, but they also set the general soak time to 15-30 minutes. Once they are clean, rinse them off thoroughly to remove any residual chemicals and place them back in your mouth or store them in water to keep them moist.

Toothbrushes

You can use a regular toothbrush or a toothbrush specially made to clean retainers (you will notice that they have a circular shape to fit in the aligner easily). To clean the retainers properly, you mustn’t use toothpaste as it can damage the retainer, the only thing you have to do is water the aligner and the brush with warm water and brush it as you do with your teeth, then rinse the aligner.

The second way to clean your retainers is using denture cleaners. It has sense as they are very similar to the retainer cleaner tablets, but it is not as safe for your aligners as the products specifically manufactured to clean them. For example, Invisalign® cannot soak in denture cleaners as the aligners can be damaged, although most work just fine in the solution. If you have spent your money on one of the best teeth aligners you won’t probably want to search one morning on the Internet “how to fix a cracked retainer” because you check with the manufacturer or read the labels to determine if your aligners were safe when using denture cleaners.

It is true that other aligners will not be damaged by denture cleaners, but some plastics can turn yellow over time when using these types of products. However, if after checking with the brand and reading the labels you find that you can use denture cleaners without damaging the aligners, the process of cleaning is very similar to the one used with retainer cleaner tablets: fill a glass with water, put the denture tablet and soak the aligners in the bubbling solution for 15-30 minutes depending on the manufacturer-s instructions.

There are more ways to clean retainers, for example using natural ingredients like baking soda, but we will talk about that later in the article. So, keep reading to find more tips on how to clean plastic retainers.

Top 4 Best Retainer Cleaners in 2021

In case you have decided to use retainer cleaners, we have compiled a list of the best ones and made a comparison table to make your final decision easier:

If your mouth appliance has wires (for example, if you have an active retainer), it cannot be soaked for more than 15 minutes.

SmileDirectClub cleaning tablets

SmileDirectClub’s tablets are very similar to Retainer Brite: same system but different process and ingredients. These tablets designed by SmileDirectClub have a shorter soaking time (only three minutes) and can also be used for dentures.

SmileDirectClub aligner brush

It’s a soft bristle brush that perfectly fits the trays and should be used without toothpaste, only with warm water.

Besides, using electric toothbrushes like this one can help you clean better your teeth compared to regular toothbrushes which can’t make as a deep clean, for example, to crooked bottom teeth due to the fact that they don’t have the shape and power to clean more difficult areas if the teeth are misaligned.

BrightByte

BrightByte is a 3 in 1 product: keeps your breath fresh, cleans your retainer, and whitens your teeth. Designed by byte still, it can be used with any plastic retainer, no matter the brand.

Other Ways to Clean Teeth Aligner Trays

We’ve just gone over a couple of techniques you can use, but there are plenty of other options as well. Whether you’re looking to remove bacteria, food particles, or stains, you’re bound to find the best option for you.

Baking Soda

Baking soda is the king of versatility; it cleans, it whitens, it freshens, it makes bread rise...really what can’t baking soda do? Well, it just so turns out that baking soda also makes a great cleaning solution. All you need to do is mix one tablespoon with one cup of warm water and soak your aligner trays for 50 minutes.

An alternative method is to make a paste out of baking soda and water and gently apply it to your trays before brushing or rinsing. Since baking soda is not very abrasive, it shouldn’t do any damage.

Hydrogen Peroxide

Hydrogen peroxide is another handy must-have to keep around your home. You simply mix equal parts water and peroxide and let your braces soak for 30 minutes. This solution kills bacteria, removes food particles, and can even help eliminate stains.

Vinegar

Vinegar isn’t quite as effective as the alternatives mentioned above, but it still sanitizes and kills bacteria and germs. To use vinegar, soak the clear braces in one part vinegar and three parts water and gently scrub away food particles. For more cleaning power you can use a 1:1 ratio as well. You can soak your retainers in this solution for 15 to 30 minutes, and you can use a soft brush dipped in the vinegar to remove stains and food particles.

Using Mouthwash

Mouthwash that contains alcohol isn’t as effective as the other options mentioned in this guide. In fact, alcohol can cause your retainer to dry out and break. That being said, mouthwash can be used once in a while as a quick freshener to get rid of any lingering odors or bacterial concerns. The best mouthwash will be any that don’t contain alcohol or other harsh chemicals. If you are tempted to use mouthwash with alcohol, make sure you only do it once in a while and for no more than a few minutes at a time.

For example, if you have a Hawley retainer you should not leave it soaking for more than 15 minutes as it has wires; if you have a plastic retainer replacement or clear aligners, you must know that using denture cleaners can turn the plastic yellow over time, and if you have a fixed bonded retainer the best way to clean it is using a toothbrush.

How to Clean Clear Retainers

Wondering how to clean plastic braces? Clear retainers include Essix and Vivera retainers, and can also include clear aligners that are used to straighten teeth. As the name suggests, they are clear, slip over your teeth, and are easy to remove. To clean your them, you can follow these general guidelines:

How to Clean Hawley Retainers

Cleaning your Hawley retainer, whether it’s a passive or active retainer, will be very similar to cleaning clear braces , but here are some general guidelines you can follow:

Fixed Retainers

The best cleaning practices for fixed retainers are a bit different than they are for either Hawley or clear braces. This type of braces are also more difficult to clean, so they will require extra effort on your part. This extra effort involves careful and diligent brushing, making sure to get under the bonded metal strip every time. It also means continuing to floss twice a day, even though this will now present more of a challenge (you can watch the video below to know how to do it properly.)

Tips for The Best Teeth Aligner Cleaning

By now you’re pretty much an expert when it comes to how to clean your retainer, but there are always opportunities to improve, so we’ve included some more useful tips and tricks below.

Soft Brush

tips teeth aligner cleaning brush

Sometimes a simple soaking isn’t enough to remove food particles, debris, plaque, or stains. In this case, you can use a soft-bristled brush to help get between those tight cracks and gaps, and remove that stubborn debris. It’s always a good idea to check with your dentist before using a brush since some plastics can be harmed by the abrasiveness. If you do scratch it from cleaning with a brush, this leaves room for bacteria to meet, greet, and spread, causing foul odors and unappealing stains.

Wash Your Hands

It’s ALWAYS a good idea to wash your hands any chance you get. You should also make sure to wash your hands before you clean your retainers.

tips teeth alignment cleaning wash hands

Washing your hands before cleaning your retainers and before removing them from their soaking solution helps prevent bacterial growth on your retainer. You should wash your hands again once you are finished cleaning so that before storing them or putting them back in your mouth, you can be sure they are completely germ-free.

Look at Your Retainers

tips teeth alignment cleaning inspect

Yes, look at and inspect your retainers closely after soaking them to make sure that they are as clean as they can get. If upon further inspection it looks like they could use some more cleaning, you can extend the cleaning time, preferably with a fresh batch of cleaning solution, but don’t do this all the time as too much chemical exposure can harm your aligners.

No Hot Water

dont use hot water tips teeth alignment cleaning

It may seem counter-intuitive since hot water is associated with killing bacteria and general cleanliness. But, hot water can soften the plastic and reshape the trays so they no longer fit the right way! The softening also makes them more susceptible to scratches and dents during brushing. You should either use lukewarm water to clean your retainers, or cold water if specified by your specific cleaner you use.

In addition to not using hot water, keep it away from high heat in general. This includes staying away from:

Also if you have a lost retainer that you find, when it turns up make sure to inspect it for any signs of heat damage.

No Harsh Chemicals

no harsh chemical to clean retainers

Harsh chemicals don’t always mean a deeper clean, and in fact, chemicals aren’t always so effective in removing bacteria. If you’re determined to achieve institutional levels of sanitizing with your retainer cleaner, ask your dentist first before giving your retainers a soak in an acid bath. In most cases, generic cleaners and natural products should be fine, anything stronger you can leave to the professionals.

Clean the Case

Clean the Case to properly clean your retainers

Cases are often forgotten when it comes to cleaning, but it is imperative to keep them clean. You should clean your case at least once a day, preferably before putting your retainer away. To clean it, just scrub all of the surfaces with warm soapy water, rinse and pat dry.
