How to Clean Your Dental Mouth Guard: A Dentist’s Guide

Keep Your Mouth Guard Fresh, Safe, and Long-Lasting

A dental mouth guard—whether for sports, teeth grinding, or nighttime protection—is an essential investment in your oral health. But to make it last and keep your mouth healthy, cleaning it the right way is key.

At Smile Lounge Dentistry in Milton, our dental experts often see patients struggling with discolored or foul-smelling mouth guards. Let’s fix that! Here’s how you can properly clean your mouth guard like a pro.

Step-by-Step: How to Clean Your Mouth Guard

1. Rinse Immediately After Use

After removing your mouth guard, rinse it thoroughly with lukewarm water. This helps remove saliva, food debris, and bacteria before they harden. Avoid using hot water—it can warp the shape of your guard.

2. Brush Gently

Use a soft-bristled toothbrush (not the one you use for your teeth) and mild, fragrance-free soap to gently clean your guard.

❌ Avoid toothpaste—it’s abrasive and can scratch the surface.

3. Use a Dental Cleaning Solution (Optional)

You can occasionally soak your mouth guard in a dentist-approved cleaning solution or non-alcohol mouthwash for about 10–15 minutes.

✔ Do this once a week to prevent bacterial buildup.

4. Rinse and Dry Completely

Always let your mouth guard air-dry on a clean surface before storing it. Keeping it damp encourages bacteria and mold growth.

5. Store in a Ventilated Case

Use a hard, ventilated case to store your mouth guard. Keep it away from direct sunlight, heat, or pets (dogs love to chew on them!).

Pro Tips from Smile Lounge Dentistry

• Replace your mouth guard every 6–12 months or when it shows wear.
• Bring your mouth guard to your regular dental checkup—our dentists can deep-clean or assess if it needs replacement.
• Never share your mouth guard, even temporarily.
