🦷 How to Clean a Night Guard (The Right Way) | Frisco TX Dentist Guide
Wearing a night guard is one of the best ways to protect your teeth from grinding (bruxism), clenching, and TMJ discomfort. But to get the most benefit from your night guard, you’ve got to keep it clean.
At Tribute Family Dentistry, we often hear questions like:
-
“How do you clean a night guard?”
-
“Can I clean my night guard naturally?”
-
“How do I clean a smelly night guard without damaging it?”
In this guide, our Frisco TX dental team breaks down everything you need to know to keep your mouthguard fresh, safe, and long-lasting—from natural methods to professional tips.
Why Cleaning Your Night Guard Is So Important
Night guards sit in your mouth for 6–8 hours every night. During that time, they’re exposed to saliva, plaque, bacteria, food particles, and biofilm buildup.
If you don’t clean your night guard regularly, it can:
-
Cause bad breath
-
Lead to bacterial infections
-
Irritate your gums or soft tissues
-
Wear down faster due to buildup
-
Make you want to stop using it altogether 😷
How to Clean a Night Guard: Daily & Weekly Routine
✅ Daily Cleaning (Takes Less Than 2 Minutes)
-
Rinse it immediately after removing it in the morning. Use cool or lukewarm water.
-
Gently brush it with a soft toothbrush. Do not use toothpaste—it’s too abrasive.
-
Let it air dry completely before putting it back in its case.
🧠 Quick Tip: Never store your night guard wet. Bacteria love moisture!
🧼 Weekly Deep Clean (Choose One)
-
Vinegar & Peroxide Soak
-
Soak your night guard in white vinegar for 30 minutes.
-
Rinse, then soak in hydrogen peroxide for another 30 minutes.
-
Rinse again and air dry.
-
-
Denture Cleaner Tablets
-
Use tablets like Polident or Efferdent in a cup of warm water.
-
Soak for 10–15 minutes. Rinse and dry.
-
-

How to Clean a Night Guard Naturally 🌿
If you prefer chemical-free options, here are effective natural cleaning methods:
🧂 Saltwater Soak
Soak your mouthguard in a cup of warm saltwater for 30 minutes. Rinse and dry.
🍋 Baking Soda Paste
Mix baking soda with water into a thick paste. Gently brush your night guard with it using a soft toothbrush. Rinse and dry.
🍎 Apple Cider Vinegar
Mix equal parts water and ACV. Soak for up to 30 minutes. Rinse thoroughly.
⚠️ Be careful not to overuse vinegar. Once per week is plenty—it’s acidic and can degrade the plastic over time.
What Not to Do When Cleaning a Night Guard ❌
Some methods may seem convenient, but they can permanently damage your night guard:
-
No hot or boiling water – it will warp the material.
-
No toothpaste – too abrasive for soft plastic or acrylic.
-
No alcohol-based mouthwash – dries out and cracks the material.
-
No dishwasher – too hot and too harsh.
How to Store Your Night Guard Properly
Cleaning is only half the battle—storage matters too.
-
Always use a ventilated case (not airtight).
-
Clean your case once a week with soap and warm water.
-
Store it in a cool, dry place, away from pets, heat, or sunlight.
-
Avoid tossing it into your backpack or bathroom counter without protection.
Can I Clean My Night Guard with Vinegar?
Yes—vinegar is a great natural disinfectant and safe to use once a week. Just soak your guard in white vinegar for 30 minutes, then rinse and optionally follow with a 30-minute hydrogen peroxide soak.
This two-step combo removes:
-
Plaque buildup
-
Bacteria
-
Bad odors
And it does it without harsh chemicals. Just remember: always rinse thoroughly and dry completely.

When Should I Replace My Night Guard?
Even if you clean it perfectly, your night guard won’t last forever. Signs it’s time to replace include:
-
Cracks or rough edges
-
A persistent bad smell
-
Discoloration or buildup that won’t clean off
-
Loose or uncomfortable fit
If you notice any of these, visit your Frisco dentist for an exam and possibly a replacement guard.
