Keeping your mouthguard clean is essential for maintaining good oral hygiene and extending the lifespan of the device. Bacteria, plaque, and even mold can accumulate on a dirty mouthguard, leading to bad breath, oral infections, and potential health risks. In this guide, we’ll cover how to clean mouthguards effectively, answer common questions about cleaning methods, and provide tips for proper maintenance.
Cleaning at Home
Proper mouthguard cleaning at home doesn’t require fancy tools or expensive products. With regular care, you can keep your mouthguard fresh, bacteria-free, and safe to use.
Step-by-Step Guide to Cleaning Your Mouthguard at Home
Rinse Immediately After Use
As soon as you remove your mouthguard, rinse it thoroughly under cool running water. This helps to wash away saliva, food particles, and debris before they harden.
Brush Gently with a Soft Toothbrush
Use a soft-bristled toothbrush (preferably separate from your regular toothbrush) to gently scrub the mouthguard. Avoid using toothpaste because it’s abrasive and can scratch the surface, creating spaces for bacteria to grow.
Use Mild Soap and Water
For deeper cleaning, mix mild, alcohol-free soap with warm water. Gently scrub the mouthguard with the toothbrush, making sure to clean all the nooks and crannies. Rinse thoroughly to remove all soap residue.
Soak in a Mouthguard Cleaning Solution
Once a week, soak your mouthguard in a non-alcoholic mouthwash diluted with water or a denture-cleaning tablet solution. This helps eliminate bacteria and keeps the mouthguard smelling fresh.
Air Dry Completely
After cleaning, place the mouthguard on a clean surface and allow it to air dry completely before storing it. Storing a wet mouthguard can encourage mold and bacterial growth.
Store in a Ventilated Case
Use a case with ventilation holes to store the mouthguard when not in use. This prevents moisture buildup, which can promote bacterial growth.
Can I Clean My Mouthguard with Chemicals?
When it comes to cleaning your mouthguard, the goal is to eliminate bacteria without damaging the material. While some chemicals can be effective cleaners, they might not be safe for your mouthguard—or your health.
Chemicals to Avoid
Bleach or Harsh Disinfectants
While bleach is a powerful disinfectant, it’s too harsh for mouthguards. It can break down the material, cause discoloration, and leave harmful residues that are unsafe for your mouth.
Alcohol-Based Mouthwash
Many mouthwashes contain alcohol, which can dry out the mouthguard, making it brittle over time. Opt for alcohol-free options if you prefer using mouthwash for soaking.
Hydrogen Peroxide (With Caution)
While hydrogen peroxide can kill bacteria, it should only be used occasionally and diluted with water. Prolonged exposure can weaken the material of your mouthguard.
Dishwasher Detergent or Hot Water
Never put your mouthguard in the dishwasher or clean it with hot water, as the heat can warp the shape of the device, making it ineffective.
Safe Cleaning Alternatives
Denture Cleaning Tablets: Designed to clean oral appliances, denture tablets are safe for occasional use with mouthguards.
Baking Soda Paste: A mixture of baking soda and water creates a gentle paste that can effectively clean and deodorize your mouthguard.
Vinegar and Water Solution: A diluted solution of white vinegar and water can help remove tough stains and odors when used occasionally.
How Often Should I Clean My Mouthguard?
Cleaning your mouthguard regularly is key to preventing the buildup of bacteria, plaque, and unpleasant odors. A clean mouthguard not only protects your oral health but also extends the lifespan of the device. Here’s how often you should clean it:
1. After Every Use (Daily Cleaning)
You should clean your mouthguard immediately after each use. This daily routine helps remove saliva, bacteria, and food particles that can cause bad breath, discoloration, and even infections.
Rinse thoroughly with cool water to wash away debris.
Brush gently with a soft toothbrush and mild, non-abrasive soap.
Air dry completely before storing it in a ventilated case.
2. Weekly Deep Cleaning
In addition to daily cleaning, perform a deep clean once a week to disinfect the mouthguard thoroughly:
Soak it in a mixture of water and a denture-cleaning tablet or an alcohol-free mouthwash.
You can also use a solution of equal parts white vinegar and water for about 30 minutes to eliminate bacteria and odors.
Rinse well and let it air dry.
3. Monthly Maintenance Check
Every month, inspect your mouthguard for signs of wear and tear:
Check for cracks, rough edges, or discoloration.
Replace it if it’s damaged or doesn’t fit properly anymore, as these issues can harbor bacteria and affect its effectiveness.
Does the Mouthguard Material Matter?
Yes, the material of your mouthguard significantly impacts both how you clean it and its overall durability. Different materials require specific care routines to maintain their structure, effectiveness, and hygiene.
1. Types of Mouthguard Materials
EVA (Ethylene Vinyl Acetate):
This is the most common material for sports mouthguards. It’s flexible, durable, and shock-absorbent. EVA mouthguards should be cleaned gently with cool water, mild soap, and a soft brush. Avoid hot water, as it can cause the material to warp.
Thermoplastic (Boil-and-Bite Mouthguards):
These mouthguards soften when heated, allowing for a custom fit. While convenient, they are more prone to wear and tear. Clean them with mild soap and cool water, and avoid hot liquids that can distort their shape.
Acrylic (Hard Mouthguards for Bruxism):
Often used for nightguards, acrylic mouthguards are rigid and designed for long-term use. They can withstand a bit more vigorous cleaning but still require gentle brushing and soaking in a denture-cleaning solution. Avoid abrasive toothpaste to prevent scratches.
Silicone:
Less common but used in some custom-fit guards, silicone is soft and flexible. It’s prone to bacteria buildup, so regular cleaning with mild soap and thorough drying is crucial. Don’t use alcohol-based solutions as they can degrade the material.
2. Why Material Matters in Cleaning
Durability: Some materials like EVA and acrylic are more durable, but they still require careful handling to avoid damage.
Temperature Sensitivity: Thermoplastic materials are sensitive to heat, which can cause them to lose shape.
Porosity: Materials like silicone can be more porous, making them more susceptible to bacteria buildup if not cleaned properly.
3. Custom vs. Store-Bought Mouthguards
Custom Mouthguards: Made from high-quality materials tailored to your teeth, they often last longer but require diligent cleaning to protect your investment.
Store-Bought (Boil-and-Bite) Mouthguards: These are more affordable but may wear out quickly. They need frequent inspections for damage and regular cleaning to prevent bacterial growth.
Maintenance Tips for Your Mouthguard
Proper maintenance of your mouthguard not only ensures its effectiveness but also prolongs its lifespan. Here are some essential tips to keep your mouthguard in top condition:
1. Clean Regularly
Daily Cleaning: Rinse with cool water and brush gently with a soft toothbrush and mild soap after each use.
Weekly Deep Cleaning: Soak in a denture-cleaning solution, alcohol-free mouthwash diluted with water, or a vinegar-water mixture to disinfect thoroughly.
2. Store It Properly
Use a Ventilated Case: Store your mouthguard in a case with holes to allow air circulation. This helps prevent moisture buildup, which can cause bacteria and mold.
Keep It Dry: Always air-dry your mouthguard completely before storing it to reduce the risk of bacterial growth.
3. Avoid Heat Exposure
No Hot Water: Never clean your mouthguard with hot water, as it can warp the material.
Keep Away from Heat Sources: Don’t leave it in direct sunlight, near heaters, or in hot cars, especially if it’s a thermoplastic type.
4. Handle with Care
Don’t Bend or Twist: Bending or chewing on your mouthguard can cause it to lose its shape.
Avoid Abrasive Cleaners: Harsh chemicals and toothpaste can scratch the surface, creating spaces for bacteria to thrive.
5. Regular Inspections
Check for Damage: Look for signs of wear, cracks, or rough edges. A damaged mouthguard can irritate your gums and be less effective.
Monitor Fit: If the mouthguard feels loose or uncomfortable, it may need adjustment or replacement.
When to Replace Your Mouthguard
Knowing when to replace your mouthguard is crucial for both hygiene and protection. An old or damaged mouthguard can harbor bacteria and fail to provide adequate support.
1. Signs It’s Time to Replace Your Mouthguard
Visible Damage: Cracks, tears, or holes in the material.
Loss of Shape: Warping or changes in fit, especially for boil-and-bite types.
Discoloration: Persistent stains or yellowing, even after cleaning.
Odor or Taste: A lingering bad smell or taste can indicate bacterial buildup that cleaning can’t remove.
Frequent Use: For athletes or people who grind their teeth at night, replace the mouthguard every 6 months or sooner if signs of wear appear.
2. Factors Affecting Replacement Frequency
Type of Mouthguard: Soft, store-bought guards wear out faster than custom-fitted ones.
Usage Intensity: Athletes in contact sports or people with severe bruxism may need replacements more frequently.
Growth Spurts: Children and teens should replace their mouthguards regularly as their mouths grow.
