How to Clean a Sports Mouthguard: Simple Tips for Hygiene and Care

 
 

A sports mouthguard is one of the most important pieces of protective gear you can own if you play contact or high-impact sports. It protects your teeth, gums, and jaw from injury—but only if it’s clean, well-cared for, and in good condition.

If you’re not cleaning your sports mouthguard properly, it can harbour bacteria, lose its shape, or become less effective. In this article, we’ll walk you through how to clean and maintain your sports mouthguard so it stays hygienic, comfortable, and protective for every game or training session.


Why Cleaning Your Sports Mouthguard Matters

Mouthguards are exposed to saliva, bacteria, and sweat every time you wear them. Without regular cleaning, they can:

  • Smell bad

  • Cause bad breath

  • Lead to gum infections or oral health issues

  • Wear out faster

A clean mouthguard is not just about hygiene—it’s about performance, comfort, and safety too.


Daily Cleaning: How to Clean Your Mouthguard After Each Use

Cleaning your sports mouthguard after every use is the best way to keep it fresh and functional. Here's a quick daily routine:

1. Rinse Immediately After Use

  • Rinse your mouthguard under cool water as soon as you take it out.

  • This removes saliva and debris before it has a chance to stick or grow bacteria.

2. Brush Gently

  • Use a soft toothbrush and a mild, non-abrasive soap or mouthguard cleaner.

  • Gently scrub the entire surface, including any grooves or edges.

  • Avoid using regular toothpaste—it can be too abrasive and damage the surface.

3. Rinse Again

  • Once cleaned, rinse thoroughly under cool water to remove any soap or cleaner residue.

4. Air Dry Before Storing

  • Pat it dry with a clean cloth or let it air dry completely before putting it in its case.

  • Never store your mouthguard while it’s still damp, as this encourages bacteria growth.


Weekly Deep Clean: Give Your Mouthguard Extra Care

A weekly deep clean helps remove lingering bacteria and keeps your mouthguard in top condition. Here are a few safe and effective methods:

Option 1: Denture Cleaning Tablets

  • Dissolve a tablet in a cup of cool or lukewarm water.

  • Soak the mouthguard for 10–15 minutes.

  • Rinse thoroughly and dry.

Option 2: White Vinegar and Hydrogen Peroxide Soak

  • Soak in white vinegar for 30 minutes.

  • Rinse, then soak in hydrogen peroxide for another 30 minutes.

  • Rinse thoroughly before use.

Tip: Always check with your dental professional before using home-made solutions to make sure they’re safe for your specific mouthguard material.


How to Store Your Sports Mouthguard Properly

Good storage habits are just as important as cleaning. To keep your mouthguard clean and in good shape:

  • Use a ventilated case to allow airflow and prevent moisture buildup.

  • Keep it away from heat, such as hot car dashboards or dishwashers—heat can warp the material.

  • Clean the case regularly using soap and water to avoid bacteria build-up.

  • Avoid wrapping it in a towel or tissue—these can trap moisture and breed germs.


What to Avoid When Cleaning Your Mouthguard

Even with the best intentions, it’s easy to make mistakes that can damage your mouthguard. Here’s what NOT to do:

  • Don’t use hot water – it can warp the shape and affect the fit.

  • Don’t use bleach or harsh chemicals – they can break down the material and irritate your mouth.

  • Don’t chew on your mouthguard – this can weaken the material and reduce its protective qualities.

  • Don’t skip cleaning – even one missed day can let bacteria take hold.


When to Replace Your Sports Mouthguard

Even the best mouthguards don’t last forever. Replace your mouthguard if you notice:

  • Cracks, holes, or tears

  • Warping or changes in shape

  • A loose or uncomfortable fit

  • Persistent odours that won’t go away

  • Growth or changes in your bite (especially for growing children)

General rule: Most mouthguards should be replaced every 6 to 12 months, depending on usage and wear.
