How to Properly Care for Your Night Guard: Tips for Maintaining Your Oral Health

A night guard is one of the simplest yet most effective tools for protecting your teeth. Whether you grind your teeth (bruxism), clench your jaw, or need support for TMJ issues, a night guard shields your smile while you sleep.

But here’s the thing—owning a night guard isn’t enough. You need to take care of it.

At Spruce Canyon Family Dentistry, we’ve seen patients get months or even years of extra life from their night guards just by following a few simple care habits. Poor maintenance, on the other hand, can turn your protective device into a bacteria trap.

This guide covers the best night guard care tips to keep your appliance clean, effective, and long-lasting.

Why Night Guard Care Matters

Your night guard spends several hours in your mouth each night. That means it collects:

• Saliva
• Plaque
• Bacteria
• Food particles

If not cleaned properly, these can lead to:

• Bad breath
• Gum infections
• Tooth decay
• Mouth sores

Plus, a poorly maintained night guard wears out faster, which means more replacements (and costs) down the road.

Daily Night Guard Cleaning Routine

The key to a clean night guard? Consistency. Here’s what you should do every single morning after wearing it:

Step-by-Step Daily Cleaning:

1. Rinse Immediately

As soon as you take out your night guard, rinse it under lukewarm water to wash away saliva and debris.

2. Brush Gently

Use a soft toothbrush (separate from your regular one) to gently brush the guard. Avoid using toothpaste—most are abrasive and can scratch the material.

3. Air Dry Completely

Place your night guard on a clean, dry surface to air dry. Avoid putting it in a closed case while wet, as this encourages bacteria growth.

Taking just 2-3 minutes each morning can dramatically extend your night guard’s lifespan.

Deep Cleaning Your Night Guard Weekly

While daily rinsing is crucial, a deeper clean once a week ensures your guard stays free from buildup.

Best Methods to Disinfect Night Guard:

• Mild dish soap and water: Use with a soft brush for a gentle yet effective clean.
• Non-alcoholic mouthwash soak: Mix with water and soak for 10-15 minutes for a fresh feel.
• Dental appliance cleaner tablets: Specifically designed to clean retainers and night guards.

Pro Tip: Never use hot water—it can warp the plastic and ruin the fit.

Your dentist near you might recommend specific cleaners depending on your guard’s material.

How to Store Your Night Guard Properly

Storage plays a bigger role than most people realize.

Do:

• Store in a ventilated case once fully dry.
• Keep the case clean by washing it weekly.
• Choose a hard case to protect from damage.

Don’t:

• Store a wet guard in a sealed container.
• Leave it exposed to direct sunlight or heat.
• Toss it in a bag unprotected.

A good habit is pairing night guard care with your toothbrush cleaning routine.

Signs It’s Time to Replace Your Night Guard

Even with the best care, night guards don’t last forever. Watch out for:

• Visible cracks or holes
• Persistent bad odor despite cleaning
• Loose fit or discomfort
• Warped shape

If you notice any of these, it’s time to contact your dentist in Aurora, CO for a replacement.

Mistakes to Avoid with Night Guard Care

Quick list of no-no’s to keep your guard in top shape:

• Don’t clean with toothpaste or harsh cleaners.
• Don’t boil or microwave to “sterilize.”
• Don’t use bleach—too harsh and can damage material.
• Don’t skip drying before storage.
• Don’t share your night guard with anyone else (obviously!).

If in doubt, a local dentist can guide you on proper cleaning products and methods.

Long-Term Oral Health Benefits of Night Guard Care

Beyond protecting the guard itself, proper care helps maintain your overall oral health:

• Reduces the risk of infections from bacteria buildup
• Prevents foul odors and stains
• Keeps your gums and teeth safe from irritation
• Supports long-term jaw health by maintaining proper appliance fit

Think of it as insurance for your smile.

When to Visit Your Dentist for a Night Guard Check-Up

Even if everything feels fine, it’s smart to have your dentist examine your night guard during regular check-ups.

Reasons for a professional night guard evaluation:

• Ensure the fit is still correct
• Check for early signs of wear
• Get recommendations for deep cleaning
• Address any jaw or bite concerns

A trusted dentist near you can spot issues early, saving you from discomfort and unnecessary expenses.
