How to Keep Your Mouthguard Clean and Fresh? A Complete Guide

Mouthguards are essential for protecting your teeth, whether you’re an athlete, a teeth grinder, or someone undergoing orthodontic treatment. However, like any oral appliance, mouthguards require regular cleaning to stay hygienic and effective. In this guide, we’ll walk you through the best practices for keeping your mouthguard clean and fresh, ensuring it remains in top condition for as long as possible.

How to Keep Your Mouthguard Clean and Fresh? A Complete Guide

Why Cleaning Your Mouthguard Is Crucial?

Your mouthguard spends a lot of time in your mouth, making it a breeding ground for bacteria, fungi, and other germs. If not cleaned properly, these microorganisms can lead to unpleasant odors, infections, and even dental issues. Additionally, a poorly maintained mouthguard can degrade faster, reducing its effectiveness and lifespan.


The Risks of Not Cleaning Your Mouthguard

  1. Bacterial Buildup: A dirty mouthguard can harbor harmful bacteria that may cause gum infections, tooth decay, or bad breath.

  2. Fungal Infections: Mold and yeast can grow on a moist mouthguard, leading to oral thrush and other infections.

  3. Decreased Lifespan: Accumulated debris can cause your mouthguard to break down more quickly, meaning you’ll need to replace it sooner.

By keeping your mouthguard clean, you’re not only protecting your oral health but also getting the most out of your investment.


Daily Cleaning Routine: The Basics

A daily cleaning routine is the first step in maintaining a fresh and hygienic mouthguard. Here’s how you can clean your mouthguard every day:

  1. Rinse Immediately After Use: As soon as you remove your mouthguard, rinse it under cool running water. This helps to remove saliva, debris, and bacteria that may have accumulated during use. Avoid using hot water, as it can warp the material.

  2. Brush Gently: Using a soft-bristled toothbrush, gently brush your mouthguard with mild, non-abrasive toothpaste. Avoid using whitening toothpaste, as it may contain chemicals that can damage the material. Brush all surfaces thoroughly to ensure that no residue is left behind.

  3. Rinse Again and Pat Dry: After brushing, rinse your mouthguard again under cool water to remove any remaining toothpaste. Then, pat it dry with a clean, soft towel. Make sure it’s completely dry before storing it, as moisture can promote bacterial and fungal growth.


Deep Cleaning: Weekly Care for Your Mouthguard

In addition to daily cleaning, your mouthguard should undergo a deep cleaning at least once a week. This helps to remove any buildup that daily cleaning might miss.

  1. Soak in a Mouthguard Cleaner: Specialized mouthguard cleaners are available that are designed to remove bacteria and odors. Follow the instructions on the cleaner, typically involving soaking the mouthguard in the solution for a specified amount of time. This process disinfects the mouthguard and helps to maintain its freshness.

  2. Use a Denture Cleaner or Vinegar Solution: If you don’t have a mouthguard cleaner, you can use a denture cleaner or a homemade solution of equal parts water and white vinegar. Soak your mouthguard in the solution for about 30 minutes, then rinse thoroughly with water. Vinegar is a natural disinfectant and can help remove any lingering odors.

  3. Check for Damage: After deep cleaning, inspect your mouthguard for any signs of wear and tear. Cracks, holes, or changes in shape can reduce its effectiveness. If you notice any damage, it may be time to replace your mouthguard.


When to Replace Your Mouthguard?

Even with proper care, mouthguards don’t last forever. Regular use and cleaning will eventually cause the material to degrade. Here are some signs that it might be time to replace your mouthguard:

  1. Visible Wear and Tear: Cracks, holes, or thinning areas indicate that your mouthguard is wearing out.

  2. Changes in Fit: If your mouthguard no longer fits snugly, it’s time for a replacement.

  3. Persistent Odors: If deep cleaning doesn’t eliminate odors, it may be due to bacterial buildup within the material, which can’t be fully removed.

Regular dental checkups can also help you determine if your mouthguard needs to be replaced.


Proper Storage: Keeping Your Mouthguard Safe and Clean

Proper storage is just as important as cleaning. How you store your mouthguard can significantly impact its cleanliness and longevity.

  1. Use a Ventilated Case: Always store your mouthguard in a ventilated case that allows air to circulate. This prevents moisture from being trapped, reducing the risk of bacterial and fungal growth. Avoid storing it in airtight containers, as they can create a damp environment.

  2. Keep It Away from Heat: Exposure to heat can warp your mouthguard, affecting its fit and effectiveness. Store it in a cool, dry place, away from direct sunlight, heaters, or other heat sources.

  3. Avoid Leaving It Out: Leaving your mouthguard out in the open can expose it to dust, bacteria, and other contaminants. Always place it in its case when not in use, and make sure the case is clean as well.


Taking care of your mouthguard doesn’t have to be a chore. By incorporating these simple cleaning and storage practices into your routine, you can keep your mouthguard clean, fresh, and ready to protect your smile.
