Why Proper Mouthguard Cleaning Matters

Why Proper Mouthguard Cleaning Matters

Your mouthguard is in constant contact with your mouth, exposing it to saliva, bacteria, and food particles. Without proper cleaning, these contaminants can accumulate, leading to:

  • Bad breath and an unpleasant taste
  • Bacterial growth, which can result in infections or gum irritation
  • Staining and discoloration
  • Faster wear and tear

By following expert-recommended cleaning techniques, you can keep your mouthguard free from harmful microorganisms and maintain its effectiveness.

How to Clean Your Mouthguard Daily 

Daily cleaning is simple and only takes a few minutes. Here’s a step-by-step guide, backed by dental professionals, to keep your mouthguard fresh and hygienic:

1. Rinse Immediately After Use

Rinsing your mouthguard immediately after use helps remove saliva, food particles, and bacteria. Use cool or lukewarm water to avoid warping the material. This quick action prevents the buildup of harmful microorganisms, which could lead to unpleasant odors or infections, ensuring a fresh and hygienic mouthguard.

2. Brush Gently with a Soft Toothbrush

Use a soft-bristled toothbrush to gently scrub the entire surface of your mouthguard. A gentle brush ensures that you don’t damage or scratch the material. Avoid using toothpaste as it can be abrasive, leading to scratches where bacteria and food particles may accumulate. This step keeps it smooth and clean.

3. Use Mild Soap for Deeper Cleaning

Mild soap or liquid dish soap is ideal for cleaning your mouthguard. Apply a small amount to your toothbrush and gently scrub the mouthguard. Unlike harsh chemicals or toothpaste, mild soap won’t damage the material, and it helps remove oils, bacteria, and any residual build-up, ensuring thorough cleanliness.

4. Dry Completely

After rinsing and brushing, it’s essential to dry your mouthguard completely before storing it. Moisture can encourage bacterial growth and mold formation. Pat it dry with a clean towel, then allow it to air-dry in a clean, well-ventilated area. A dry mouthguard is key to maintaining its hygiene and longevity.

Deep Cleaning Your Mouthguard: A Weekly Routine

In addition to daily cleaning, it’s important to deep clean your mouthguard at least once a week. Here are some effective methods for a more thorough cleaning:

Dental Cleaning Tablets

Soak your mouthguard in a solution of non-abrasive denture or retainer cleaning tablets dissolved in water. This will eliminate bacteria and odors, giving your mouthguard a fresh, clean feel. Follow the instructions on the product for best results.

Hydrogen Peroxide and Water

Mix equal parts of hydrogen peroxide and water in a bowl. Soak your mouthguard for 15–20 minutes, then rinse it thoroughly. This helps disinfect the guard and remove any lingering bacteria.

White Vinegar and Water

For a natural cleaning solution, mix equal parts white vinegar and water. Soak your mouthguard for 15–30 minutes to remove buildup, disinfect, and reduce any odor. After soaking, rinse it well to avoid lingering vinegar smell.

Pro Tip: Avoid using hot water to clean your mouthguard, as it can distort the material. Never use bleach, as it can damage the guard and pose health risks.

How to Properly Store Your Mouthguard

Proper storage of your mouthguard is just as important as cleaning. Here’s how to store it correctly:

  • Ventilated Storage Case: Always store your mouthguard in a case with ventilation holes to prevent moisture buildup, which can promote bacterial growth.
  • Keep It Dry: Ensure the guard is completely dry before storing it to avoid any mold or bacteria growth.
  • Avoid Sunlight or Heat: Never leave your mouthguard in direct sunlight or near heat sources, as this can warp the material.
  • Keep Away from Pets: If you have pets, ensure your mouthguard is out of reach, many pets love to chew on these.

How to Tell When It’s Time to Replace Your Mouthguard

Despite regular cleaning and careful storage, mouthguards have a lifespan. Replace your mouthguard if:

  • Cracks or Tears: If your mouthguard develops visible cracks or tears, it can no longer provide effective protection. This damage could lead to discomfort or reduced performance.
  • Loses Its Fit: Over time, mouthguards can lose their snug fit due to wear. If it no longer fits properly, it may cause irritation or discomfort during use.
  • Persistent Odor or Stains: Persistent odors or stains that can’t be removed with cleaning may indicate bacterial buildup or material degradation. A replacement is necessary for optimal hygiene.
  • Excessive Wear: If your mouthguard shows signs of thinning, uneven surfaces, or wear patterns, it’s losing its protective ability and should be replaced to ensure proper function.

Most mouthguards last 1–5 years, depending on their use and care.

Final Thoughts: Maintain a Clean, Safe Mouthguard

FAQs

Can I use toothpaste to clean my mouthguard?

No, it’s not recommended to use toothpaste. While it may seem like a good idea, toothpaste can be abrasive and cause scratches on your mouthguard. These scratches trap bacteria, leading to potential infections and bad odors. Use mild soap instead to gently clean your mouthguard.

How often should I deep clean my mouthguard?

It’s ideal to deep clean your mouthguard once a week. More frequent cleaning may be necessary if you’re sick, have a cold, or notice a buildup of bacteria. Regular deep cleaning helps maintain hygiene and ensures your mouthguard stays fresh and odor-free.

What should I do if my mouthguard smells bad?

If your mouthguard develops an odor, perform a deep cleaning using dental cleaning tablets, hydrogen peroxide, or vinegar solution. If the smell persists, it may be time for a replacement as lingering odor could indicate bacteria or material degradation.

Is it safe to soak my mouthguard in mouthwash?

While mouthwash can help reduce bacteria and freshen your mouthguard, it’s not the best option for deep cleaning. The alcohol in many mouthwashes may also weaken the material over time. Use a mild soap or a dental cleaning tablet for more effective cleaning.

How long should I soak my mouthguard for deep cleaning?

For deep cleaning, soak your mouthguard for 15-30 minutes in a cleaning solution (such as hydrogen peroxide or vinegar). Do not leave it in the solution for longer periods, as it may damage the material.

How do I disinfect my mouthguard during flu season?

During flu season or if you’re sick, disinfect your mouthguard more frequently. Use hydrogen peroxide or a non-abrasive denture cleaner to ensure it’s free from germs and bacteria. Rinse it thoroughly after cleaning before wearing it again.

Can my mouthguard cause mouth sores?

A poorly fitted mouthguard can rub against the gums and cause irritation, leading to mouth sores. Ensure your mouthguard fits properly and is not damaged. If you experience persistent irritation, consult your dentist to adjust or replace it.

Can I clean my mouthguard with a dishwasher?

No, it is not recommended to clean your mouthguard in a dishwasher. The high temperatures and detergents can warp the material and affect its fit. Stick to hand cleaning with cool water and mild soap to avoid damaging the guard.

How can I avoid my mouthguard getting discolored?

To prevent discoloration, regularly clean your mouthguard and store it in a well-ventilated case. Avoid exposing it to foods or drinks that may stain, such as coffee or tea. Regular deep cleaning will also help maintain its appearance.
