The Importance of Cleaning Your Nighttime Mouth Guard

Maintaining proper hygiene for your nighttime mouthguard is essential for several reasons. Neglecting its cleanliness can lead to various oral and general health-related issues. Here’s why keeping your mouth guard clean is crucial:

Oral Health:

Wearing a mouth guard at night creates an environment where bacteria and fungi can thrive, providing warmth and moisture. These microorganisms can multiply, leading to oral infections, bad breath, and cavities. Regular cleaning helps eliminate these harmful organisms, ensuring your oral health remains intact.


A dirty mouth guard can become uncomfortable to wear. The buildup of bacteria and debris can cause irritation, sores, or an unpleasant taste. A clean mouth guard ensures a comfortable and irritation-free experience during your sleep or sporting activities.


Proper care and cleaning can significantly extend the lifespan of your mouth guard. Neglecting regular maintenance may cause the material to deteriorate or develop an unpleasant odour, leading to the need for frequent replacements, which can be costly in the long run.

Cleaning Materials and Supplies

Before diving into the cleaning process, gathering the necessary materials and supplies is essential. Here’s a list of items you’ll need:

  1. Toothbrush: A soft-bristle toothbrush is ideal for cleaning your mouth guard as it won’t scratch or damage the surface.
  2. Toothpaste: Mild, non-abrasive toothpaste is suitable for gently cleaning your mouth guard. Avoid using harsh or abrasive toothpaste, as it can cause damage.
  3. Mild Soap: Liquid dish soap or hand soap can also be used for cleaning. Ensure it’s free from harsh chemicals and fragrances.
  4. Antiseptic Mouthwash: An antiseptic mouthwash can help disinfect and freshen your mouth guard. Make sure it’s alcohol-free to prevent damage to the mouthguard material.
  5. A Soft Cloth or Towel: Use a clean cloth or towel to dry your mouth guard after cleaning.

Step-by-Step Cleaning Process

Now that you have your cleaning materials ready let’s walk through the step-by-step process to maintain your nighttime mouth guard:

Step 1: Rinse Immediately After Use

After removing your mouth guard in the morning, rinse it thoroughly with cold or lukewarm water. This step helps remove surface debris and prevent the buildup of bacteria.

Step 2: Brush Gently

Gently brush your mouth guard using a soft-bristle toothbrush and a small amount of mild toothpaste or soap. Please pay close attention to all surfaces, including the inside, where it comes into contact with your teeth and the outside. Avoid hot water, as it can distort the mouth guard’s shape.

Step 3: Rinse Again

After brushing, rinse your mouth guard thoroughly with water to remove any remaining toothpaste or soap residue. Ensure that no cleaning agents are left on the mouth guard, as they can affect the taste and safety of the device.

Step 4: Soak in Antiseptic Mouthwash

To disinfect your mouth guard, immerse it in a container filled with antiseptic, alcohol-free mouthwash. Let it soak for a few minutes to kill any remaining bacteria or fungi.

Step 5: Rinse and Dry

After soaking:

  1. Rinse the mouth guard with cold or lukewarm water to remove any residual mouthwash.
  2. Pat it dry with a soft cloth or towel.
  3. Avoid using paper towels or tissues, as they can leave behind lint or particles.

Step 6: Store Properly

Store your clean and dry mouth guard in a ventilated container designed for this purpose. Ensure it’s kept in a cool, dry place away from direct sunlight, as excessive heat can damage the material.

Additional Tips and Precautions

Here are some extra tips and precautions to keep in mind while maintaining your nighttime mouth guard:

  1. Avoid Hot Water: Never use hot water to clean or rinse your mouth guard, as it can warp or deform the material.
  2. Regular Inspection: Periodically check your mouth guard for any signs of damage, such as cracks or loose parts. Contact your dentist for repairs or a replacement if you notice any issues.
  3. Replace as Needed: Over time, mouthguards can wear out due to usage and cleaning. Depending on your mouth guard type, your dentist may recommend replacing it after a certain duration.
  4. Consult Your Dentist: If you have any concerns or questions about cleaning your specific type of mouth guard, don’t hesitate to consult your dentist for personalized guidance.
