How to clean a mouthguard without ruining it
The 30-second routine our dental lab recommends, plus the weekly deep clean and the mistakes that warp a guard.
Why it matters
Clean guard, healthy mouth
Your mouthguard spends hours against your teeth, collecting bacteria, plaque and whatever was on the gym floor. A dirty guard can cause bad breath and gum irritation, and it wears out faster. Keeping it clean takes 30 seconds.

The right tools make it easy
Storage
Store it right
Where your guard sits between sessions matters as much as how you clean it.
Do
Always use a vented case
Air circulates so it dries fully between uses.
Don’t
Never loose in a gym bag
It collects bacteria and gets crushed.
Don’t
Keep it away from pets
Dogs love mouthguards, and a chewed guard cannot be repaired.

FAQ
Frequently asked questions
How do I clean my TRUFIT mouthguard?
Rinse it and give it a few sprays of cleaning spray after every use, let it air dry, and soak it with a cleaning tablet once a week.
Can I use denture or retainer cleaning tablets?
Yes, in cool water as the package says. They are a good weekly deep-clean option.
Can I soak it in mouthwash?
Skip alcohol-based mouthwash. Alcohol degrades and discolors the material over time.
Can I put a mouthguard in the dishwasher?
Never. Heat warps any mouthguard: dishwashers, boiling water and hot cars all do the same damage.
How often should I clean my mouthguard?
Rinse and spray after every use and do a tablet soak once a week.
My mouthguard smells even after cleaning. Now what?
Odor that survives a deep clean means bacteria are trapped in the material. It is time to replace the guard.
Do I need to clean the case too?
Yes. Wash the case weekly with soap and water and let it dry open, or it can re-contaminate the guard.
