In this comprehensive guide, we’ll explain how to clean a mouthguard and smart habits to ensure its longevity. Let’s dive into everything you need to know about keeping your mouthguard clean and your smile protected.

Why Cleaning Your Mouthguard Matters

Whether you use a mouthguard for sport or other reasons, keeping it clean is essential to its effectiveness and your oral health. Here’s why regular cleaning is so important:

How To Clean Mouthguard useProtect Your Oral Health

A clean mouthguard helps minimise bacterial growth, reducing the risk of irritation or plaque buildup on your teeth and gums.

Extend Its Lifespan

Routine cleaning and proper storage can help your mouthguard stay in good condition for longer, saving you from needing frequent replacements.

Prevent Bad Odours

Without daily care, mouthguards can start to smell unpleasant. Cleaning helps keep them fresh, comfortable, and ready to wear.

Avoid Cross-Contamination

Using a separate toothbrush and a clean bowl and letting it dry completely on a flat surface helps prevent cross-contamination from surfaces or other oral care items.

Types Of Mouthguards

Different mouthguards serve different purposes, from protecting your teeth during sports to preventing the effects of nighttime grinding. Here’s what you need to know:

  • Night Guards For Bruxism: Night guards, commonly used for sleep bruxism (teeth grinding), are worn during sleep to protect against enamel wear and jaw strain.
  • TMJ Splints: These advanced appliances are custom-made to help manage temporomandibular joint (TMJ) discomfort or misalignment.
  • Sports Mouthguards: Designed for use during high-impact sports, sports mouthguards help protect against dental injuries.

 

 

How To Clean Mouthguards

Keeping your mouthguard clean is simple but essential. Following a consistent daily routine can help preserve its shape, reduce bacterial growth, and maintain freshness. Here’s how to clean mouthguards effectively:

Step 1: Rinse Immediately After Use

When you remove your mouthguard, rinse it thoroughly under cool or lukewarm water. Avoid hot water, as high temperatures can warp the material and affect the fit.

Step 2: Gently Brush With A Separate Toothbrush

Using a separate toothbrush, gently brush all surfaces of your mouthguard. A nonabrasive toothpaste or mild antibacterial soap removes debris without damaging the material. Be thorough but gentle; scrubbing too hard may create micro-tears that can harbour bacteria.

Step 3: Sanitise With Mouthwash Or Cleanser

For an added level of cleanliness, briefly soak your mouthguard in an alcohol-free mouthwash, a cleanser solution, or a mixture of warm water and antibacterial soap. Alternatively, an occasional soak in equal parts hydrogen peroxide and water or a diluted OTC denture cleaner can offer a deep clean. Just be sure to use enough liquid to fully submerge the dentures in a clean glass or bowl.

Step 4: Rinse Thoroughly

After sanitising, rinse your mouthguard again under cool water to remove any residual cleaning agents. This helps maintain a neutral taste and reduces the chance of irritation during wear.

Step 5: Let It Dry Completely On A Flat Surface

Let your mouthguard dry completely on a clean flat surface before storage. This step is key to preventing bacterial growth and bad odours. Avoid storing it while damp or in a sealed container.

  • Visible wear or cracks
  • Changes in fit or comfort
  • Persistent bad odours despite cleaning
  • Warping from hot water or direct sunlight

Speak with your dentist about getting a replacement, especially if using a custom-fitted mouthguard.

Smart Habits For Mouthguard Users

Building a few smart habits into your daily routine can help you get the most out of your mouthguard, keeping it clean, comfortable, and long-lasting. Here’s what we recommend:

  • Brush Your Teeth Before Wearing: A clean mouth reduces the risk of bacterial growth on your mouthguard.
  • Rinse Before And After Use: Rinse your mouthguard before putting it in and after taking it out.
  • Clean After Each Use: Stick to a daily cleaning habit to prevent buildup.
