If you’re one of the millions of people who use retainers (oral appliances such as dentures and aligners), then you know that they need to be clean on a regular basis. Not cleaning them can cause them to accumulate bacteria and food particles, which can lead to bad breath (halitosis) and even tooth decay. In this blog post, we’ll be discussing the health benefits of cleaning retainers on a regular basis and providing tips on how to remove food particles from retainers. So don’t wait any longer – clean your retainers today!

Tips on Removing Food Particles from Retainers

It’s important to clean your retainer regularly to keep it looking and performing its best. To clean it effectively, first be sure not to use harsh cleaning chemicals – this will damage the plastic material of your retainer. To clean it, remove food particles by rinsing them in clear water and then scrubbing with a toothbrush or loofah. Finally, dry your retainer thoroughly before storing it away. If the particle stubbornly refuses to come off, wet the retainer again and place it in the dishwasher on the top rack for 20 minutes.

Fixed Retainers

Fixed retainers are cemented to your teeth, they are not removable but they still need attention on top of your oral care routine.

  1. Brush your teeth regularly.
  2. Use a long piece of floss with a threader on the end of it, or you can also use super foss.
  3. Pass the floss through the retainer and your teeth to remove any debris.
  4. Do this for every tooth.
  5. Rinse with mouthwash (optional).

Clear Plastic Retainers

Clear aligners and other products similar to Invisalign are designed to be removed for up to two hours a day. They are designed this way so they are easier to clean and eat with, however, you will want to keep them in your mouth as much as possible and only remove them for a minimal amount of time.


  1. Before every meal, remove your retainer.
  2. After each meal, brush your teeth.
  3. Clean your retainer gently with mild dish soap and a soft bristled brush.
  4. Wash all the soap off.
  5. Re-insert the retainer/aligner tray immediately back into your mouth afterward.

Hawley Retainers

Hawley retainers are made of an acrylic tray with metal wiring that attaches to your teeth, these retainers are most likely what you think of when you imagine a traditional retainer.


  1. Remove the retainer before your meal.
  2. Brush it with a soft-bristled toothbrush.
  3. Use a denture cleaner, baking soda, or retainer cleaner.
  4. Keep it moist while it is out of your mouth (in a glass of water, or wrapped in a damp paper towel, etc.).
  5. Soak the retainer in denture cleaner overnight for a deep clean.

Signs You Need To Clean Your Retainer Or Aligner

As mentioned before, you should be cleaning your dental appliance every day, at least once a day. If you have a habit of forgetting to clean your appliance, you should be on the lookout for these signs. 
  • Bad smell from a retainer. 
  • Unexplained bad taste in your mouth.
  • The retainer has a cloudy appearance.
  • It’s been a day or two since you’ve cleaned it.

Dental Appliance Cleaning Myths

If you have an appliance, or you need to get one, you might have heard about these appliance cleaning myths. It’s good to do your own research, but you will want to ask your dentist to make sure the things you found are evidence-based and true.

You Only Need Water To Clean Your Appliance

Water does clean it to an extent, but to get rid of bacteria you will want to use an actual cleaning solution formulated to do this, water may not be effective at deep cleaning the appliance. However, if you are stuck in a situation where you don’t have any other way to clean your appliance, then using only water is better than using nothing.

You Don’t Need Daily Cleaning

You should seriously consider cleaning your dental appliance once a day. Even if you don’t notice, the lack of cleaning may give you bad breath. It will also promote tooth decay by allowing bacteria and food debris to build up. 

Retainer Cleaning Products Are Damaging

This is not true, ask your dentist for a product they endorse and your appliance should be ok if you follow the instructions. These products are specifically formulated to keep your appliance as clean as possible without damaging it.
