How to Clean a Mouth Guard

Introduction

A mouth guard can quickly accumulate bacteria, plaque, and odors if it isn’t cleaned regularly. Proper cleaning not only keeps it fresh but also helps maintain its shape and ensures it remains safe for daily wear. With the right techniques, you can clean your mouth guard thoroughly using simple household items.

What You'll Need

• Soft toothbrush

• Mild dish soap

• Lukewarm water

• Non-alcohol mouthwash (optional)

• Antibacterial denture cleaner or retainer tablets (optional)

• Clean towel or case

Steps

Rinse the mouth guard under lukewarm water to remove loose debris.
Apply a small amount of mild dish soap to a soft toothbrush. Gently brush the entire surface of the mouth guard, paying close attention to grooves and edges.
Rinse thoroughly under lukewarm water until all soap residue is gone.
Pat the mouth guard dry with a clean towel and let it air-dry completely before placing it back in its case.
Clean the storage case with soap and water and let it dry before storing the mouth guard again.

Alternative Methods

• Soak the mouth guard in non-alcohol mouthwash for 10 minutes to freshen and disinfect.

• Use a denture-cleaning or retainer tablet in a cup of water for deep cleaning.

• Mix equal parts water and hydrogen peroxide and soak for 10 minutes to remove odors and kill bacteria.

What NOT to Do

• Do not use hot or boiling water, as it can warp the mouth guard.

• Avoid toothpaste, which is abrasive and can scratch the material.

• Do not soak in alcohol-based mouthwash, which can degrade the plastic.

• Avoid using harsh chemicals like bleach.
