Caring for a Mouthguard Properly
Short answer. Good mouthguard care for athletes comes down to rinsing after every use, cleaning gently, drying fully, and storing it in a ventilated case. A chewable oral probiotic such as ProDentim, as the seller describes it, is a separate question and does not replace any of those steps.
- Rinse the guard after each session, not just when it looks dirty.
- Heat, rough scrubbing and harsh chemicals can warp or scratch the material.
- A closed, damp bag is the worst place to keep a mouthguard.
- A probiotic supplement does not clean or protect the guard itself.
- A dentist can check fit and tell you when a guard is worn out.
The mistakes that show up most often
Most problems start in the gym bag. A guard gets pulled out, used, pushed back into a sealed case while still wet, and left there for a day or two. Moisture, saliva and sugary drink residue stay in contact with the plastic, and the guard ends up carrying a film you can often smell.
Other common slips: sharing a guard with a teammate, chewing on it between drills, and leaving it on a dashboard or near a radiator, where heat can bend it out of shape. A guard that no longer fits snugly is not doing its job.
A simple routine that takes two minutes
After each session, rinse the guard under cool running water and brush it gently with a soft toothbrush and a little mild soap or non-abrasive toothpaste. Rinse again, shake off the water and let it air dry completely before it goes anywhere near a case.
Once in a while, give it a closer look in good light. Cracks, thin spots, sharp edges or a loose fit mean it is time to ask about a replacement.
- Rinse in cool water, never hot
- Use a soft brush and mild soap
- Air dry fully before storing
- Keep it out of direct sun and hot cars
Storage: where the guard lives between sessions
A rigid case with air holes is the usual advice, because it protects the guard from being crushed while letting moisture escape. Keep the case itself clean too: wash it with soap and water every so often and dry it, since a grimy case undoes the work you did on the guard.
Avoid loose pockets, wrapping it in a towel or leaving it on the bench. Pets and little hands find guards surprisingly interesting.
Does an oral probiotic belong in this conversation?
Some athletes wonder whether a chewable oral probiotic changes how they should look after a guard. It does not. A supplement does not clean plastic, and nothing about it removes the need for rinsing, brushing and drying.
As the seller describes it, ProDentim is a dietary supplement sold as a chewable oral probiotic. The seller's page names three strains: Lactobacillus paracasei, Bifidobacterium lactis BL-04 and Lactobacillus reuteri. Research on oral probiotics is still early and mixed, and none of it is about this product specifically, so treat it as an optional extra, not a fix.
Who should ask a professional first
Anyone who is pregnant or breastfeeding, taking medicines, living with a medical condition or managing allergies should ask a dentist, doctor or pharmacist before using any supplement. The seller's own page says the same for pregnancy, nursing, medication and medical conditions. Parents should also check before offering anything to a child.
Read the label on the bottle itself. The seller's page does not show per-strain amounts or a full supplement facts panel, and its wording varies between tablet, candy and supplement. If something is unclear, ask the seller before buying.
Persistent gum soreness, a guard that rubs or cuts, loose teeth or a bad taste that does not clear are reasons to book a dental visit, whatever supplements you use.
Questions readers ask
How often should a mouthguard be replaced?
There is no single schedule. Replace it when it is cracked, thin, misshapen or no longer fits firmly, and ask your dentist to check it at routine visits, especially for growing teenagers.
Can I soak a guard in mouthwash?
Some mouthwashes can discolor or degrade the material, so check what the guard maker or your dentist recommends. Plain soap and cool water is the safe default.
Does a probiotic make my guard cleaner?
No. Cleaning the guard is a hands-on job done with water, a soft brush and drying time. A supplement is a separate decision about your mouth, not your equipment.
What if my guard smells even after cleaning?
Check whether it dries fully and whether the case is clean. If the smell stays, or your own breath has a persistent odor, mention it to your dentist.
Talk to a professional. Persistent bleeding, pain, swelling, loose teeth or sores that do not heal need a dentist's attention, not a supplement.
