What is a Retainer? How To Clean A Retainer?


What is a retainer?

Before we learn how to clean your retainer, it’s important to understand what a retainer is. This is a dental appliance designed to shape the shape of your teeth. It is designed to fit perfectly in your mouth and reposition your teeth so they align properly. They are made of a rubber ring that goes over the front of your teeth and into your mouth.



The grip of this teeth maintenance tool on the teeth is very strong.. Some retainers clasp directly onto certain braces, depending on your preference. Orthodontists recommend using this tool after removing your braces

In America over 5 million people use braces. After removing your braces, it is advisable to start using dental guards as a final step in your alignment treatment. It is also advisable to wear your dental guar dseveral hours in a row, preferably at night, to get the results you are looking for.

Different Types Of Retainers

There are quite a few types of retainers on the market, including:

1. Hawley Retainers

These are detachable retainers and they are commonly known for the hard material and wire used in their production.

2. Clear Essix Retainers

These kinds of retainers are also detachable and are mostly made of transparent material.

3. Permanent/Fixed Retainers

These are mainly custom-fitted retainers that are normally bound to the inner side of your teeth. To install or remove these types of retainers you have to visit your orthodontist.

What is the work of a retainer?

This is designed to support your teeth. When you have crooked teeth, you will first use braces to adjust and align your dental formula. Once your braces finish their work and are taken off, your orthodontist will suggest a retainer for your teeth. As such, retainers are used after you have removed your braces to help your teeth conform to their new position.

Normally, teeth move around your mouth, when talking, chewing, biting, swallowing, or conducting any movement at all. As such, the position of your teeth is never stagnant throughout your life. Nothing can stop this movement, but if worn properly this helps hold your teeth down, aiding those seeking alignment.

What are the advantages and disadvantages of a retainer?

These are great for aesthetics, but there are some advantages and disadvantages to using them that may not be obvious. Let’s take a look at the pros and cons below before buying retainers:

Advantages of Retainers

  • It aligns our teeth to give us a beautiful smile
  • It strongly holds down our teeth to prevent movement and help keep the teeth in their new position

Disadvantages of Retainers

  • They are quite fragile, which means you must handle them with care otherwise you will likely damage them
  • They require regular maintenance, failure to which they will become damaged and most likely affect the overall health of your mouth
  • It requires a lot of discipline due to the precise cleaning guidelines and the fact that if you stop wearing it, your teeth will naturally fall back to their original state.

How long do you have to wear a retainer?

Once installed, it firmly holds your teeth to prevent or limit their movement. When you have removable retainers, wear them for at least 12 months before you are allowed to remove them. Every day, you may wear your teeth protector for 12-23 hours, making it very easy for bacteria to grow.

How to clean your retainer properly?

The first step to take whenever you take off your retainer is to rinse it. Rinsing helps get rid of all the saliva and reduces bacteria build-up to a minimum. You should do this daily.

Practice a weekly deep cleaning procedure for your teeth protector. You can pick a day for this, but always ensure to wash your protector using dish soap, hydrogen peroxide, white vinegar, or baking soda every once a week.

Properly cleaning your teeth protector ensures that you always maintain a fresh breath and avoid infections that could result from getting a cut or sore in your mouth. There are quite a few ways to maintain proper retainer hygiene, and they are listed below.

Best Way: Clean your retainer with water

The best way to clean clean your teeth protector is definitely by using water. Once you remove it, soak it in warm water. Always be very accurate about the water temperature since you don’t want to soak it in hot water as it may become distorted. Leave it in the water for a few minutes before introducing it to a toothbrush with soft bristles.

Once you remove it from the warm water, brush its surface gently with your soft-bristled brush. Your brush should not have any fragrance, coloration, or flavor. Your retainer is made from acrylic material, which is quite fragile when introduced to harsh conditions. As such, it is important to avoid:

  • Using hot water
  • Soaking your dental guard for extended periods
  • Using a coarse toothbrush or a rough cleaning material
  • Rubbing too hard when brushing your dental guard
  • Using normal soap could be highly toxic. You could use Castile soap as it is less toxic, and thus more suitable.

In-Mouth Cleaning

If you don’t want to remove your retainer, you can still clean it while it’s still in your mouth. Take a sizable sip of lukewarm water, and let it sit in your mouth for a few minutes before swirling and spitting it out.

Filling up a syringe with some clean, warm water, squirting it out, and then using air pressure to blow it out is quite effective in eliminating food particles and avoiding build-up between the wires. After cleaning your retainer, you can then remove it and allow it to dry naturally, or use a clean piece of cloth to pat it dry.

How to clean your retainer with Toothpaste, Mouthwash, and Dental Floss?

According to orthodontists, it is recommended to brush your teeth using toothpaste and rinse off your mouth with mouthwash just before taking out your dental guard. Go ahead and place your dental guard on a soft piece of cloth and brush it gently with a soft-bristled toothbrush. Doing this is necessary to remove food particles and plaque that may still be clinging to your retainer.

Dental floss is quite useful as it can go in between the grooves of your teeth protector to remove any leftover food particles. Be careful not to use dental floss on the wire framework of your teeth protector. A tongue scraper or a U-shaped metal tool will easily remove any bacteria from your tongue, both underneath and ab

Once that’s done, you will realize it becomes much easier to brush out any dirt that has built up on your dental guard. It is now time to rinse and dry out your dental guard before placing it back into your mouth. Ensure you have completely rinsed out all the toothpaste and mouthwash before using a soft towel to dry your teeth protector.

We recommend cleaning your retainer every time you brush your teeth by gently brushing it with a soft toothbrush. Make sure you thoroughly clean it at least once every week.

How to clean your retainer with baking soda?

Pre-mix your solution by adding some lukewarm water into baking soda and then dip your retainer in there. Leave it soaked for at least 15 minutes before removing it and using a soft toothbrush to clean it. Rinse thoroughly with a saline solution to ensure you have removed all the baking soda grit.

If you find any hidden food particles after washing, use the saline solution to help remove them, leaving your dental guard clean and fresh. Feel free to use any brand of saline solution available to you. The most important part is ensuring that you have removed all the baking soda, so be thorough with the rinsing process.

If you are using Hawley retainers, baking soda could easily destroy the welded metal parts. Be careful with this cleaning procedure if you have either fixed, bonded, or lingual wire teeth protectors. You can still use the baking soda method, but you must be extremely cautious by reducing the amount of baking soda in the solution and the frequency you use this particular cleaning method.

Those using polyurethane and plastic dental guards have nothing to worry about, in fact, this cleaning method can be pretty sufficient. Since these dental guards are not made with solder metal, they will not react to the baking soda solution.

Things to avoid when cleaning your retainer

Never clean your teeth protector using toothpaste or anything you may consider abrasive. Your teeth protector will likely come out scratched, which is not healthy for you as bacteria can easily build up and give your dental guard a cloudy appearance.

Your dental guard is quite fragile, as such, it is not advisable to run it through hot water or even through a dishwasher. It could easily melt or become distorted

Avoid using mouthwash, alcohol, or even bleach on your dental guard. The chemicals contained in these substances could easily cause your retainer to distort.

Why do we need to maintain our retainer regularly?

Regularly maintaining our retainers is not only good for ensuring a long lifespan for these devices, but also for maintaining the overall health of our mouths. It is recommended to clean your teeth protector at least once every day. You should also do a thorough cleaning of your teeth protector weekly; it is best to set a day for it.

Regular maintenance of our retainers helps us curb bacterial growth and imminent infections in case of a cut or any injury within the mouth. Besides, poor care can lead to:

  • Bad breath/smell
  • Tiny white spots
  • Foul taste
  • Cloudy appearance
  • Layer of film

Besides, if you fail to clean your dental guard regularly, it becomes even more difficult to clean due to the piled-up plaque that has probably already hardened. Also, as food and bacteria accumulate in the grooves of your dental guard, it will likely start irritating your gums, cutting them, and even causing them to recede, which is never a good thing. You want to maintain a healthy mouth; so maintain a clean dental guard.


It is important to keep your retainer clean and without any odor at all times. However, most cleaning methods out there will leave your retainer scratched, creating room for bacteria to grow and hide.

Mildly clean your dental guard daily, and set apart a day for a thorough cleaning every week. If you are not sleeping with your teeth protector in your mouth, always ensure to soak it in clean, distilled water to keep it fresh and moist. You don’t want any food particles to dry on your teeth protector, which is what will happen if you leave it open and dry.

If you are not sure about how to go about the cleaning process, you can choose to take it to your dentist, who will likely do a great job cleaning it for you. If you choose to do it yourself, avoid using harmful chemicals or even hot water.

Properly caring for your teeth protector should ensure that it serves you effectively and for a long time. Your mouth will also be grateful for the proper care and it will remain healthy throughout your retainer-use duration.
