A mouthguard is one of the simplest and most essential pieces of protective gear in MMA — but it’s also the one fighters neglect the most. Leaving it in your gym bag, tossing it on the locker-room bench, or forgetting to clean it properly leads to bacteria growth, bad odors, and a shorter lifespan for your gear.
A good mouthguard case protects your mouthguard from germs, dirt, and damage, while proper hygiene habits keep you healthier and safer during training. Whether you’re a beginner or a seasoned fighter, taking care of your mouthguard is non-negotiable.
This guide breaks down the best mouthguard cases available today and the most effective hygiene practices every fighter should follow.
Why a Good Mouthguard Case Matters
A quality case helps you:
- Prevent bacterial buildup
- Keep your mouthguard dry
- Improve airflow to reduce odor
- Protect it from getting crushed in your gym bag
- Avoid contamination from dirty surfaces
- Maintain long-term durability
It’s a small upgrade that has a big impact on your hygiene and safety.
Features to Look for in a Mouthguard Case
When choosing a case, look for:
1. Ventilation
Allows airflow, prevents moisture buildup, and reduces bacteria growth.
2. Durable Shell
Protects against compression, drops, and gym bag pressure.
3. Anti-Microbial Material
Some cases use special coatings to resist bacteria.
4. Easy-to-Clean Design
Simple shapes are easier to rinse and sanitize.
5. Secure Closure
Prevents the case from popping open in your bag.
6. Size Compatibility
Should fit your exact mouthguard style (single or double layer).

Mouthguard Hygiene Tips Every MMA Fighter Should Follow
A mouthguard collects bacteria faster than nearly any other piece of gear. Follow these essentials to keep it clean and safe.
1. Rinse Before and After Training
Use cool or lukewarm water. Avoid hot water — it warps the mouthguard.
2. Use a Gentle Soap or Mouthguard Cleaner
A quick scrub removes sweat, saliva, and bacteria.
3. Dry It Completely Before Storing
Moisture = bacteria growth.
Let it air dry on a clean surface before putting it in the case.
4. Never Store It Loose in Your Gym Bag
Gym bags are full of:
- Sweat
- Oils
- Bacteria
- Dirty clothes
A case is your only barrier.
5. Avoid Keeping It in Your Car
Heat can melt or warp the material.
6. Deep Clean Once a Week
Use:
- A denture tablet
- Mouthguard cleaning solution
- A gentle anti-microbial soak
This keeps it fresh and odor-free.
7. Replace the Mouthguard When Needed
Don’t keep using it if:
- The edges wear down
- It doesn’t fit snugly
- It starts to crack
- It smells even after cleaning
A damaged mouthguard won’t protect you properly.
How to Build Hygienic Habits Into Your Training Routine
You can keep hygiene simple by creating a quick post-training ritual:
- Rinse
- Clean
- Dry
- Store in case
- Pack for next time
Just 90 seconds a day protects your health, your teeth, and your gear.
Final Takeaway
A mouthguard is only as safe as the care you give it. The right case keeps it protected, and good hygiene habits ensure you’re not putting harmful bacteria into your mouth during every session. For fighters who train hard and often, this small routine makes a big difference in performance and long-term health.
Clean gear = healthy training.
Healthy training = consistent progress.
