Why Cleaning Your Mouthguard Matters
Your mouthguard spends hours pressed against your teeth, collecting everything your mouth produces — bacteria, plaque, and whatever was on the gym floor when you dropped it. An unclean guard can cause bad breath, gum irritation, and even illness, plus it wears out faster.
The good news: keeping it clean takes 30 seconds.
Here is the routine our dental lab recommends.

Custom-Fit VS Boil-and-Bite
Not all mouthguards are the same.
Custom-Fit
-
Dental-grade materials
-
Stays secure in place
-
Built for daily use
-
Better comfort and protection
Boil-and-Bite
-
Breaks down over time

Wears down faster

Needs frequent replacing
Storage
Store it right. Protect your investment.
Always store in a ventilated case.
Vents let air circulate so it dries fully between uses.
Don’t store loose in a gym bag.
It collects bacteria and get crushed or damaged.
Keep it away from dogs & pets.
They love mouthguards, and a chewed custom guard is not repairable.
When to Replace
Replace your mouthguard if you notice any these:
Fit feels loose or different
Material is cracked, torn, or worn down
Odor or buildup that won’t clean off

How do I clean my TRUFIT mouthguard?
Refer to the information on this page for cleaning tips & tricks
-
Can I use denture tablets?
Yes, in cool water per the package — a good deep-clean option.
-
Can I soak it in mouthwash?
Skip alcohol-based mouthwash — alcohol degrades and discolors guard 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; use cleaning tablets weekly; deep-clean monthly.
-
My mouthguard smells even after cleaning — now what?
Persistent odor after a deep clean means embedded bacteria — 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 the case can re-contaminate the guard.
