A night guard protects your teeth from nighttime grinding and clenching (bruxism). To keep it working properly, you need to clean and maintain it regularly. Without proper care, a night guard can collect bacteria, develop odors, or lose its shape. The good news? A few simple habits can keep it clean, safe, and long-lasting.
Why Cleaning Your Night Guard Matters
Your night guard stays in your mouth for hours every night. During that time, it collects saliva, plaque, and bacteria. If you don’t clean it properly, this buildup can lead to:
- Bad odors
- Discoloration
- A slimy or sticky surface
- Mouth irritation
- Increased bacteria in your mouth
Daily cleaning protects your oral health and helps your night guard last longer. Let’s look at the simple steps you can follow to keep your night guard clean and in great condition.
How to Clean and Care for Your Night Guard
1. Rinse It Every Morning
Right after removing your night guard, rinse it under lukewarm water. This washes away saliva and loose debris before it hardens.
Avoid hot water — it can warp soft or thermoplastic night guards.
2. Brush It Gently With a Soft Toothbrush
Use a soft-bristled toothbrush to gently clean all sides of the night guard.
Keep in mind:
- Do not use toothpaste — it is abrasive and can scratch the material.
- Avoid stiff or hard brushes.
- Use water alone or a mild, non-abrasive liquid soap.
This removes plaque without damaging the night guard.
3. Deep Clean It Weekly
A weekly deep clean keeps your night guard fresher and more hygienic. You can use:
- Denture-cleaning tablets
- A night guard–specific cleaning solution
- A mild, non-abrasive soap with warm water
Avoid bleach, alcohol, hydrogen peroxide, or harsh cleaners — these can weaken the material and leave harmful residue.
4. Let It Dry Completely
Moisture encourages bacterial growth. After cleaning, place your night guard on a clean surface and let it air-dry fully. Drying time ranges from 30 minutes to several hours depending on material. Avoid storing a damp night guard whenever possible.
5. Store It in a Ventilated Case
Use a protective case with ventilation holes. Proper airflow prevents moisture buildup and keeps bacteria from multiplying.
Clean the case weekly with warm, soapy water.
6. Avoid Heat and Hot Water
High temperatures can warp most night guards—especially soft or thermoplastic ones. A warped night guard may no longer fit properly.
To prevent damage:
- Avoid hot water
- Don’t leave it in a hot car
- Keep it away from sunlight
- Never put it in the dishwasher
7. Watch for Signs of Wear
Even high-quality night guards wear down over time. Contact your dentist if you notice:
- Cracks
- Sharp or rough edges
- Deep bite marks
- A loose fit
- Pain or discomfort when wearing it
Soft guards typically wear out faster, while hard acrylic guards last longer.
8. Bring It to Your Dental Checkups
Bring your night guard to routine dental visits. Your dentist can:
- Check for wear
- Adjust the fit
- Professionally clean it
- Tell you when it’s time for a replacement
This keeps your night guard effective and comfortable.
When Should You Replace Your Night Guard?
You may need a new night guard if:
- It feels loose
- It causes irritation
- It has cracks, holes, or deep wear marks
- It no longer protects your teeth
- Your bite has changed
A worn or poorly fitting night guard may worsen grinding or strain your jaw.
