Stay game-ready with Caspersmile Sports Mouthguards
Protect your teeth on and off the field with a guard that's durable, comfortable, and custom-made. Play hard without worrying about your smile.
Daily care routine: Simple mouth guard cleaning tips
First things first. Every single time you use your guard, it needs at least some basic care. Skipping this is like brushing your teeth once a week and expecting a fresh smile; it doesn't work.
Here's what you should do:
Rinse right after use
Don't just toss it in your pocket or into your sports bag. Run it under cool or lukewarm water immediately to wash away saliva and debris. Hot water is a no-go; it can warp the shape.
Brush gently
Use a soft toothbrush (not the one you brush your teeth with, please!) and mild soap. Toothpaste might seem like a good idea, but many formulas are abrasive and can scratch the surface.
Air dry completely
This is a step a lot of people forget. Moisture is an invitation for bacteria. Let your guard dry fully before storing it away.
Caspersmile recommends following a set daily care routine for their mouth guards. Keeping your Caspersmile Mouth Guards scratch-free and bacteria-free not only extends their life but also protects your gums and teeth from irritation.
Storage strategies: Smart mouth guard storage tips
Cleaning is half the job. Storage is the other half. Think of it like your phone, you would not just drop it anywhere and hope it survives. The same rule applies here.
Use a ventilated case
A sturdy, ventilated case protects the guard from damage and lets it breathe. Throwing it unprotected in your gym bag is a guaranteed way to invite bacteria and cracks.
Clean the case too
What's the point of cleaning the guard if the case itself is dirty? Give the case a quick rinse or scrub every week.
Deep cleaning: Keeping mouth guard hygiene in check
Daily rinsing is great, but your guard still needs a proper deep clean to stay fresh. Here's how you can step it up:
Weekly soak
Drop your guard into a cleaning solution or a mild antibacterial rinse. This clears away buildup that brushing alone won't.
Natural cleaning methods
A soak in vinegar followed by hydrogen peroxide works as a DIY disinfectant. Just don't forget to rinse thoroughly afterward.
Avoid harsh chemicals
Bleach or alcohol-based solutions may sound powerful, but they actually weaken the material and shorten the life of your guard.
Most mouthwashes contain alcohol or dyes that damage mouthguards.
Inspection & replacement
Even if you clean and store your guard properly, wear and tear is inevitable. That is why you should:
-
Look for cracks, holes, warping, or discoloration. If your guard smells bad even after cleaning, it's a red flag.
-
Know when to replace. Over-the-counter guards might last a few months. Sports guards often need replacing every season. Custom acrylic night guards, like those from Caspersmile, can last much longer if cared for properly.
-
Do not use a worn-out guard. A loose or cracked one won't protect your teeth and may even irritate your gums.
Tips to maximize lifespan & safety
Bad habits can shorten your guard's life faster than you think.
-
Don't chew on it like gum.
-
Never share it with anyone.
-
Bring it along to your dental checkups so your dentist can inspect it.
-
Brush and floss your teeth before putting them in.
-
Keep them away from pets.
These simple habits not only help prevent mouth guard damage but also make the whole experience more hygienic and comfortable.
Mouth guard maintenance made simple
Taking care of your guard doesn't have to be complicated. A rinse, a brush, smart storage tips, and the occasional deep clean, that's all it really takes. Combine that with regular inspections, and you'll not only extend the life of your guard but also protect your oral health.
If you're still using an old, ill-fitting guard, it might be time to upgrade. Caspersmile offers high-quality custom night guards that are affordable, durable, and built for real protection. With the right care, they'll stick with you for the long haul.
So the next time you wonder about how to care for your mouth guard, remember, cleaning a sports mouth guard or a night guard is not just about longevity. It's about giving your teeth the protection they deserve.
