How to Clean Each Type of Retainer

How to Clean Your Retainer

Your retainer sits inside your mouth. So the food and plaque on your teeth can build up on your retainer. Just like with brushing your teeth, your retainer also needs to be kept clean. Find out how to keep retainers clean and how often you should clean them.

Why Wear a Retainer?

After your braces are removed, your teeth need help to stay in their new place. Your orthodontist will probably prescribe a retainer to help minimize movement. You may have to wear your removable retainer for at least 12 months after your braces are removed.

Your teeth move naturally throughout your life. When you speak, swallow, chew, and bite, these movements can cause your teeth to move. Nothing can fully stop your teeth from moving, but retainers can help if they’re worn properly.

You may have to wear your retainer anywhere between 12 hours and 23 hours a day. This means that bacteria can easily build up on your retainer.

Types of Retainers

There are several types of retainers, including:

  • Hawley retainers: These are removable retainers that are made of a hard material and wire.
  • Clear Essix retainers: This type of removable retainer is made from a transparent material.
  • Permanent or fixed retainers: These retainers are bonded to the tongue side of your teeth and are custom fitted. They can be placed and removed only by your orthodontist.

A study found that participants wearing clear Essix retainers had more plaque and tartar (dental calculus) buildup than those wearing Hawley retainers.

In the U.S., healthcare spending accounts for 17.7% of the Gross Domestic Product (GDP), or the total value of goods and services produced by the entire nation for the entire year, according to the Centers for Medicare & Medicaid Services.

How to Clean a Retainer

Brush your retainer. After eating, rinse your retainer with warm water. Brush your teeth. Use a separate toothbrush to gently brush your retainer.

You may also use a small amount of gentle dish soap to clean your retainer.

Use a cotton swab. You may also use a cotton swab to clean the nooks and crannies of your retainer.

How to Deep-Clean a Retainer

There are a few different ways of deep-cleaning your removable retainer. Talk to your orthodontist to find out which is suitable for your type of retainer.

Baking soda water. You may deep-clean your removable retainer in a mixture of baking soda and water. If you have a Hawley retainer, don’t soak it for too long or too often. The baking soda solution may corrode the metal parts of your retainer.

Because an Essix retainer doesn’t have metal parts, it can be soaked in the baking soda solution longer and more often.

Denture cleaners. You may also use denture cleaners to clean your dirty retainer twice a week. Fill a small container with water and denture cleaner. Rinse your retainer. Soak it in the denture cleaner solution for 20 minutes. Rinse your retainer. Then soak it in nonalcoholic mouthwash for 20 minutes.

How to Clean Fixed Retainers

You can’t remove your permanent retainers to clean them. But you can clean your fixed retainers the same way you clean your teeth — by flossing and brushing.

Flossing around your permanent retainer can be tricky. You may want to use special dental floss or floss threaders that are designed for retainers. A water flosser may also be useful.

Because you can’t remove your fixed retainers to deep-clean them, you should also visit your dentist for regular checkups and cleanings.

What to Clean Retainers With

Here are some cleaning agents to avoid.

Toothpaste. Regular toothpaste may rub off the surface of your retainer. This may cause bacteria to stick to it. Instead of toothpaste, make a paste of equal parts baking soda and water. Use this paste to scrub your retainer.

Hot water or high temperatures. Don’t boil your retainer or use hot water to wash it. Heat can permanently warp the plastic materials of your retainer. You may then need to replace your retainer.

Bleach. This chemical is too harsh for your retainer and may damage it.

Alcohol. Avoid cleaners that contain alcohol. Alcohol can cause your retainer to dry out.

How Often Should You Clean Your Retainer?

Experts say that you should clean your retainer at least once a day. You may also want to deep-clean it in an antibacterial denture cleaner once a week. This can help kill any bacteria on your retainer.

If you don’t regularly clean your retainer, it can result in:

  • Small white spots
  • Bad smell
  • Bad taste
  • Layer of film
  • Cloudy look

Retainer Maintenance Tips

Wash your hands. You risk transferring germs into your mouth if you don’t wash your hands first. Wash your hands before and after you handle your retainer.

Brush or rinse. After eating and before putting your retainer back in your mouth, try to brush your teeth or rinse your mouth.

Make it a habit. Once you take your retainer out of your mouth, clean it right away. This makes it easier to remove any food particles and makes it less likely that debris will harden on your retainer.

You can set a reminder on your phone. This will help remind you not just to clean your retainer but also to wear it.

Use the right retainer storage. Talk to your orthodontist to find out the best way to store your retainer when you’re not wearing it. Some retainers may need to dry out, while other types may need to be soaked. Check with your orthodontist about what type of soaking solution your retainer needs.

Remember your retainer case. Always carry your retainer case with you. You may damage your retainer if you drop it into your bag or pocket without a case.

Clean your case. Your retainer case may have more bacteria than your retainer. When your retainer is soaking, use the time to clean your case.

Don’t use a napkin. Try not to wrap your retainer in a napkin or tissue. It’s easily mistaken as trash and thrown away.

Avoid heat. Don’t leave your retainer in a hot car, near a heater, or near a hot stove. This can deform your retainer.

Keep it away from pets. Your dogs can easily chew up and damage your retainer. Keep your retainer away from your pets.

Do I have to clean my retainer?

If you wear a retainer, you might be wondering how to care for it. Your retainer sits inside your mouth and against your teeth, so it quickly accumulates bacteria, plaque, and tartar. Just like you brush your teeth every day, it’s important to clean your retainer every day.

Many people need to wear a retainer full time for a while after they have their braces removed. This is because teeth aren’t set in a rigid environment. Even after they’ve been corrected by braces and moved into a better position, they can shift over time.

Retainers help the muscles and tissues in your mouth hold teeth in their new placement. Some people may even need to wear their retainers at night indefinitely to keep teeth in place.

Here’s more about the different types of retainers, how to clean them, and other tips to keep them well-maintained.

Caring for your retainer starts with identifying which kind you have. There are three types of retainers:

  • Hawley retainers are molded out of acrylic to fit your mouth. They have a wire that helps hold the retainer in place. This type of retainer is removable, so it’s easy to clean.
  • Clear plastic retainers may go by the names Essix, Vivera, or clear aligners. These retainers slip over your teeth and are pretty much invisible. They’re easy to remove, but aren’t as durable as Hawley retainers.
  • Fixed, or bonded, retainers may also be called permanent retainers. These are actually attached to your lower front teeth. They’re used if you have a high risk of having your teeth shift. You can’t remove this type of retainer. It’s usually put into place for months or even years.

Hawley and clear plastic retainers

Both Hawley and clear plastic retainers can be removed from your mouth for daily cleaning.

To clean your Hawley or clear plastic retainer, follow these steps:

  1. Make sure you clean your retainer as soon as you remove it from your mouth, while it’s still wet. This will make it easier to clean off any debris before it hardens.
  2. Brush out your retainer with lukewarm water after each meal. It’s a good idea to brush your teeth at this time as well.
  3. For a deeper clean, mix lukewarm water with mild dish soap (toothpastes are abrasive and can scratch the retainer’s surface). Use a soft toothbrush or denture brush to gently scrub away plaque and other debris.
  4. If necessary, use a cotton swab to get into the deepest grooves and ridges on clear plastic retainers.
  5. Ask your dentist about soaking your retainer in a denture or retainer cleaner, like Efferdent or Polident. If they recommend soaking, mix a cup of lukewarm water with one tablet of cleaner and follow the package instructions for timing.

If you notice debris on your retainer that won’t come off, take it to your dentist or orthodontist. There are special solutions that can remove stubborn tartar.

Fixed, or bonded, retainers

These retainers are attached to your teeth, so you must floss them daily to keep them clean. This process may seem intimidating at first, but you’ll eventually get the hang of it. Here’s how to clean your permanent retainer:

  1. Grab a 6-inch piece of floss and use a floss threader to thread the floss between your two front lower teeth.
  2. Hold one end of the floss with your fingers and the other with the threader.
  3. Once you get the floss under your retainer wire, simply move it up and down between the teeth all the way to the gum line. The floss should gently go below the gum line if possible.
  4. Slide the floss sideways to the next area you want to clean. Pull down until it’s between your teeth.
  5. Repeat this process with each tooth that’s attached to your permanent retainer.

If you’re having a hard time flossing, don’t hesitate to ask for help from your dentist or orthodontist. They can help guide your technique and provide more tips.

1. Avoid heat

Exposing your retainer to high heat can warp and ruin it. Keep your retainer away from:

  • boiling water
  • microwaves
  • dishwashers
  • washers and dryers
  • the dashboard of your car

Always wash retainers in lukewarm water.

2. Skip the chemicals

You don’t necessarily need to use harsh cleansers to get a squeaky-clean retainer. In fact, in a study on Essix retainers, researchers discovered that using chemical cleaning tablets didn’t reduce the number of bacteria any more than simple brushing did.

That being said, the tablets were effective at removing “cocci” bacteria, like Streptococcus bacteria, the cause of strep throat. Strep throat is an infection in the throat and tonsils that causes a sore throat, fever, and red, swollen tonsils.

3. Time your soak

If you do choose to use tablets, don’t soak a Hawley retainer for too long. Doing so can corrode the metal components. Only soak the retainer for the time it takes to clean it, or as specified on your cleaning tablets.

You can do a quick mouthwash soak if you want to freshen your retainer’s smell and kill some bacteria. Be sure to mix equal parts mouthwash and lukewarm water.

If your mouthwash contains alcohol, only soak your retainer in this type of a solution occasionally. Alcohol can harm your retainer’s plastic.

4. Clean your case

Also make sure to clean your retainer case regularly. Try cleaning it once a day before you put your retainer away. Gently scrub all surfaces pf it in warm, soapy water. Then rinse it off and pat to dry.

5. Keep watch

You’ll want to keep your retainer away from pets so they don’t chew or choke on it. Likewise, be mindful of where you place your retainer while you’re eating. If you place it on a napkin, you may forget it or accidentally toss it in the trash.

6. Replace as needed

Retainers are somewhat like contact lenses or shoes: They’re subject to daily wear and tear. Eventually, they may need to be replaced. Essix retainers may only last six months to a few years, as the plastic tends to wear out. Hawley retainers can last 5 to 10 years if properly cared for.

Contact your orthodontist if you notice that your retainer is particularly dirty, worn out, or no longer fits properly.

Your retainer will keep collecting bacteria, plaque, and tartar from your mouth while you wear it. Over time, it may even start to smell or taste funny if you don’t clean it often enough.

More importantly, retainers can harbor dangerous bacteria like Streptococcus, including S. sanguinis, S. mitis, and S. salivarius, in addition to Lactobacillus and Veillonella. While many bacteria are normally found in the mouth, when too many build up, they can cause illness.

You may also become exposed to Candida albicans. This is detrimental yeast that’s normally found inside the mouth, but it may accumulate on your retainer and cause an infection.

Streptococcus and Candida may not be big threats if you have a healthy immune system. If your immune system is compromised in some way, though, you need to be more careful. Let your doctor know right away if you notice any redness, swelling, or other worrisome symptoms in your mouth.

Cleaning your retainer is just as important as brushing your teeth. You need to clean your retainer in warm water and dish soap once a day to keep it healthy. It’s a good idea to brush it out after each meal as well. The tips in this article are general, so it’s always best to ask your dentist or orthodontist for specific care instructions for your retainer.
