That custom-fitted mouthguard you’ve invested in is now an essential part of your kit.
It’s been moulded precisely to one of the most important players on the team – you.
But achieving that perfect fit was only the beginning… Like any piece of high-performance gear, its effectiveness now depends entirely on how well you look after it.
This is our professional guide to proper mouthguard care.
Why Proper Mouthguard Care Matters
A mouthguard often ends its life at the bottom of a dark, damp sports bag. We see the impact of poor hygiene all the time:
- It’s a Breeding Ground for Germs: Without daily cleaning, a mouthguard collects bacteria, plaque, and even mould. That’s the last thing you want in your mouth before a big game…
- A Damaged Guard is a Useless Guard: Once a mouthguard is warped, cracked, or thinning, it cannot absorb impact the way it was designed to. Its protective ability is gone.
- Your Investment Lasts Longer: Custom guards are built to be durable, but they need help staying that way. Simple care prevents the material from degrading, so you get season-long protection for your money.
- A Clean Guard Gets Worn: No athlete wants to put a foul-tasting, gritty mouthguard in. A clean, comfortable guard is one that actually stays in the mouth, where it can do its job.
How to Clean Your Mouthguard Properly
At the end of a long training session or a tough match, the last thing on anyone’s mind is mouthguard hygiene. But a quick, two-minute routine here is what separates a guard that lasts a season from one that’s binned in a month. These small habits are the foundation of good mouthguard care…
After Every Use
This is non-negotiable. Before it goes anywhere near a kit bag:
- Rinse It: Use cool running water. Never use hot water (it will warp the custom fit instantly). We see this happen all the time, and it’s an expensive mistake to make.
- Brush It: With a soft-bristled toothbrush (not your regular one), gently clean all the surfaces with a mild soap or a specific mouthguard cleaner. Skip the toothpaste. It’s too abrasive and will create tiny scratches where germs can hide and multiply.
- Dry It: Let it air dry completely on a clean surface before storing it away.
Weekly Deep Clean
Once a week, you need to sanitise your mouthguard to deal with the stubborn bacteria a quick rinse can’t shift. This is key to preventing odours and staining.
Soak the mouthguard in a specialist mouthguard cleaning solution or an effervescent denture cleaner for about 30 minutes. These products are designed to disinfect without damaging the material. Afterwards, give it one final rinse and let it dry.
Easy.
How to Store Your Mouthguard Correctly
Most mouthguards aren’t damaged during play. They’re crushed in kit bags, chewed by the family dog, or warped on car dashboards.
This is why every mouthguard we supply at Mobile Mouthguards comes in a firm, ventilated case. The vents allow air to circulate, preventing mould from growing in a dark, damp container.
Keep the case clean and always store it in a cool, dry place. A hot car is a mouthguard’s worst enemy.
When to Replace Your Mouthguard
Even a well-cared-for mouthguard has a lifespan. You need to know when it’s time for a new one:
- Look for Damage: Regularly check for any cracks, thinning patches, or signs of wear. If the fit feels loose, it’s no longer providing proper protection and needs replacing.
- The New Season Check (Especially for Kids): Young athletes grow. Their jaws and teeth change from one season to the next. A mouthguard from last year will rarely fit correctly a year later. We strongly recommend a new fit every single season for children and teens so their protection keeps up with their growth.
- After Dental Work: Any new fillings, crowns, or orthodontic adjustments mean the old guard is obsolete. You’ll need a new fitting.
Our entire service is built around making this process as simple and straightforward as possible. We can come to your home or organise a session for the whole team at your club. See How It Works or Book Online to schedule a visit.
Final Thoughts: Protect Your Investment (and Your Smile)
Your mouthguard is as standard as boots, pads, or a helmet and looking after it should be part of every athlete’s routine.
Proper maintenance protects your oral health. It also protects your investment. In following these simple steps, you will guarantee your custom mouthguard delivers the powerful protection it was designed for, game after game.
