How to Clean Your Mouthguard the Right Way: Dentist-Approved Tips
Wearing a mouth guard protects your teeth from grinding, sports injuries, and other nighttime dental issues—but are you cleaning it correctly? Just like your toothbrush or retainer, your mouth guard collects bacteria, plaque, and debris. If you don’t clean it regularly, it could cause bad breath, gum irritation, and even infection.
Whether you use a mouthguard for bruxism, sports, or sleep apnea, learning how to care for it properly helps you prolong its lifespan and maintain your mouth’s health. Here’s a dentist-approved guide to keep your mouth guard in top condition.
Why Cleaning Your Mouth Guard Matters
Your mouthguard sits in your mouth for hours, often overnight. During that time, it collects saliva and bacteria that build up throughout the night. If you store it without rinsing or disinfecting, you’re giving bacteria a free pass to grow—and putting that right back into your mouth later.
A dirty mouth guard can lead to:
- Foul odors
- Gum disease
- Tooth decay
- Oral infections
Cleaning it daily—and storing it properly—reduces the risks and improves your oral hygiene.
Daily Cleaning Tips from Dentists
The good news? Cleaning your mouthguard doesn’t require any fancy tools. You can maintain a clean environment with everyday products and habits.
Step-by-Step Daily Cleaning:
- Rinse Immediately After Use: As soon as you remove your mouthguard, rinse it under cool water. Don’t use hot water—it can warp the material.
- Brush Gently with a Soft Toothbrush: Use a separate toothbrush to brush the guard gently. Avoid using toothpaste, which may scratch the plastic. Instead, opt for mild dish soap or antibacterial hand soap.
- Dry Completely Before Storing: Pat it dry with a clean towel and leave it out for 15–30 minutes before placing it in its case. A dry environment discourages bacterial growth.
Weekly Deep-Cleaning for Better Hygiene
In addition to daily rinsing, deep-clean your mouth guard once or twice a week. A dentist in Winter Springs would recommend using denture cleaner tablets or a non-alcoholic mouth rinse. Soak your mouthguard for up to 10 minutes, then rinse and dry it thoroughly.
Avoid These Cleaning Mistakes:
- Using bleach or harsh chemicals
- Scrubbing with toothpaste
- Leaving it in direct sunlight
- Storing it wet
Each of these can damage your mouthguard or reduce its effectiveness.
Don’t Forget the Case!
Your mouthguard case can also collect bacteria and debris. Clean the case weekly with soap and water and let it dry completely. Never store your guard in a dirty or wet case.
When to Replace Your Mouth Guard
Even with proper care, mouthguards don’t last forever. Inspect yours regularly for signs of wear:
- Cracks or tears
- Warped shape
- The foul smell that won’t go away
- Discoloration
If you notice any of these, it’s time for a replacement. Keeping your guard in good condition helps protect your teeth and gums effectively.
Keep Your Mouth Guard—and Mouth—Fresh
Your mouthguard plays a crucial role in maintaining your oral health, but only if you properly maintain it. Cleaning it daily, deep-cleaning weekly, and replacing it when needed will keep your smile safe and fresh. If you’re unsure whether your guard is still doing its job or if you need a custom fit, your dentist can help.
