But how exactly do you go about cleaning your retainer?

And what are some of the common myths associated with retainer cleaning? Read on to find out!

Do I have to clean my retainer?

Absolutely! Retainers are made of sturdy materials like acrylic, but they’re still porous enough to allow bacteria and plaque buildup.

This is why it’s not only important to clean your retainer regularly but also to ensure that it’s completely dry before putting it back in.

Retainer cleaning varies by type:


  • Pros: Very easy to clean;
  • Cons: May wear away with too much scrubbing; It can be hard to get all of the nooks and crannies.


  • Pros: Can be cleaned using the same strategies as a stock retainer
  • Cons: It may cost more than a stock retainer; Retainers made of acrylic can be easy to break, which may cause discomfort or the inability to wear your retainer.

However, if this isn’t possible due to time constraints or a busy schedule, cleaning your retainer, every other use is acceptable, as well.

How to deep clean retainers

As mentioned earlier, cleaning varies by types of retainers as follows:

How to clean a stock retainer

  • Soak in hot, soapy water for 10 minutes.
  • Use a soft-bristled toothbrush to gently scrub all the nooks and crannies.
  • Give it another soak in hot, soapy water to remove any remaining residue.
  • Rinse thoroughly and let it air dry.

How to clean a custom retainer

  • Clean the retainers using the same steps as above, but skip the soaking in hot water.
  • Acrylic can warp when it comes in contact with high temperatures, which could cause discomfort or the inability to wear your retainer.

How not clean your retainer

There are many things that you should never do when cleaning your retainer.

Avoid the following:

  • abrasive agents or toothpaste
  • strong chemicals
  • rough scrubbing
  • boiling water
  • dishwasher detergent
  • harsh brushes

Any of these can warp, crack, or even break your retainer.

As a general rule of thumb, it’s highly recommended that you clean your retainer every after use, with most dentists recommending that you do so before bedtime.

For those with hectic schedules or simply don’t have the time to clean their retainers daily, cleaning them every other day is acceptable.

If you cannot get your retainers clean on time, it’s best to store them in a glass of water with some mouthwash or hydrogen peroxide mixed with it.

This will help to keep them sterile and in good condition. Although it’s not advisable, you can also choose to wear your retainer in a pocket or a storage container.

However, this could potentially lead to unsanitary conditions and body fluids building up on your retainers over time. This can lead to discomfort and make your retainers more difficult to wear.
