Forget superficial advice; this is your definitive roadmap to maximizing the health and safety benefits of your athletic mouthguard.
The Unseen Dangers: Why Proper Mouthguard Care Isn’t Optional
Before we dive into the “how,” it’s crucial to grasp the “why.” Neglecting your mouthguard isn’t just about a potential bad odor or a shorter lifespan for the device; it’s about exposing yourself to a host of health risks that can undermine your performance and well-being.
Bacterial Breeding Ground: A Hidden Threat
Your mouth is a teeming ecosystem of bacteria, both beneficial and harmful. When you wear a mouthguard during physical exertion, it’s exposed to sweat, saliva, food particles, and potentially even blood. Without proper cleaning, these elements combine to create an ideal environment for bacterial growth. Imagine a petri dish for microbes, warmed by your body heat and kept moist – that’s your uncleaned mouthguard.
Consider this: A study published in the Journal of Sports Science & Medicine found that uncleaned athletic mouthguards can harbor a significant number of bacteria, including species associated with oral infections and even systemic diseases. These aren’t just minor annoyances; we’re talking about potential candidiasis (thrush), gum infections like gingivitis and periodontitis, and even more serious gastrointestinal issues if harmful bacteria are ingested.
Concrete Example: After a vigorous basketball game, you simply toss your mouthguard into your gym bag. Over the next few hours, residual saliva, sweat, and perhaps a rogue potato chip crumb become a nutrient-rich buffet for bacteria. When you next put that mouthguard back in your mouth, you’re essentially reintroducing a concentrated dose of these microbes directly onto your oral tissues, significantly increasing your risk of infection.
Material Degradation: Compromising Protection
Beyond the microscopic threats, improper care also takes a toll on the physical integrity of your mouthguard. The materials used in athletic mouthguards, typically EVA (ethylene-vinyl acetate) or similar thermoplastics, are designed for resilience but are not indestructible. Exposure to extreme temperatures, harsh chemicals, or even prolonged moisture can cause them to degrade.
This degradation manifests as hardening, softening, cracking, or losing their customized fit. A mouthguard that no longer fits snugly or has developed cracks is inherently less effective at absorbing impact and distributing force. Its ability to cushion blows and prevent dental trauma is severely compromised, putting your teeth, jaw, and brain at greater risk of injury.
Concrete Example: You habitually leave your mouthguard on the dashboard of your car after practice. On a hot summer day, the interior of your car can reach temperatures well over 60°C (140°F). This intense heat can cause the EVA material to soften and warp, permanently altering its shape and fit. When you try to use it again, it feels loose, shifts around, and provides a fraction of the protection it once did.
Immediate Post-Use Care: The First Line of Defense
The moment you remove your mouthguard after use is the most critical time for initial cleaning. This immediate action prevents the establishment of bacterial colonies and the drying of organic matter, which can become much harder to remove later.
Rinse Thoroughly with Cold Water
The very first step, and arguably the most important, is a thorough rinse with cold or lukewarm water. This isn’t just about removing visible debris; it’s about flushing away as much loose saliva, sweat, and food particles as possible before they can adhere or dry onto the surface.
Actionable Explanation: As soon as you take your mouthguard out, hold it under a running tap of cold water. Use your fingers to gently rub all surfaces – inside and out, paying particular attention to any grooves or indentations where debris might accumulate. The cold water helps to prevent any proteins in saliva from “cooking” onto the surface, which can lead to stubborn stains and odors. Continue rinsing for at least 30 seconds, ensuring every part of the mouthguard has been thoroughly washed.
Concrete Example: After a muddy rugby match, your mouthguard might have visible dirt, grass, and saliva on it. Don’t just wipe it with your hand. Immediately go to a sink and hold it under the cold tap, using your thumb and forefinger to vigorously rub off any external grime and flush out the inside. You’ll see the water carry away the loose debris.
Gentle Cleaning with Mild Soap or Mouthguard-Specific Cleanser
While rinsing is crucial, it’s not enough to eliminate all bacteria. You need a cleaning agent. The key is to use something mild that won’t damage the mouthguard material.
Actionable Explanation: After rinsing, apply a small amount of mild, non-abrasive soap (like liquid hand soap or dish soap without harsh chemicals) to a soft-bristled toothbrush (one dedicated solely to your mouthguard, not your teeth!) or a clean cloth. Gently brush or wipe all surfaces of the mouthguard. Focus on areas that come into direct contact with your teeth and gums, as these are prime spots for bacterial buildup. Avoid using toothpaste, as many contain abrasive agents that can scratch the mouthguard’s surface, creating microscopic nooks and crannies where bacteria can hide. If you prefer, there are many mouthguard-specific cleaning solutions available that are formulated to be gentle on the material while effectively sanitizing.
Concrete Example: You’ve just finished a particularly sweaty boxing session. After rinsing your mouthguard under cold water, put a pea-sized drop of fragrance-free liquid hand soap on a soft toothbrush. Gently scrub the entire surface of the mouthguard, both inside and out. You’ll feel the slight foam indicating the soap is working. Once you’ve scrubbed thoroughly, rinse again completely to remove all soap residue.
Rinse Again Thoroughly
This step is often overlooked but is absolutely vital. Any residual soap or cleanser can leave a film on the mouthguard, potentially affecting its taste, feel, and even posing a mild irritant to your oral tissues.
Actionable Explanation: After cleaning with soap or cleanser, rinse the mouthguard under cold running water for at least a minute. Continuously rub the surfaces with your fingers to ensure all traces of the cleaning agent are removed. Hold it up to the light to check for any suds or film.
Concrete Example: After brushing your mouthguard with soap, hold it under the tap and let the water run over it while you rub every surface. You want to feel no sliminess or slipperiness, just the clean texture of the mouthguard material.
Deeper Cleaning and Sanitization: Beyond the Daily Routine
While daily cleaning is paramount, periodic deeper cleaning and sanitization are necessary to eliminate more resilient bacteria and maintain optimal hygiene.
Effervescent Denture/Mouthguard Cleaning Tablets
These tablets are specifically designed to clean oral appliances and are highly effective at sanitizing mouthguards. They work by releasing oxygen bubbles that help to lift away plaque, stains, and kill bacteria.
Actionable Explanation: Once or twice a week, or more frequently if you use your mouthguard daily for intense activity, consider using an effervescent cleaning tablet. Follow the manufacturer’s instructions, but generally, you’ll drop one tablet into a glass of lukewarm water (never hot, as it can deform the mouthguard) and submerge your cleaned mouthguard. Let it soak for the recommended time, usually 10-20 minutes. The bubbling action will help loosen debris and kill bacteria.
Concrete Example: Every Sunday evening, as part of your weekly gear clean-up, drop a denture cleaning tablet into a small cup of lukewarm water. Submerge your previously rinsed and cleaned mouthguard, ensuring it’s fully covered. Let it sit for 15 minutes while you do other chores. After the time is up, remove it, rinse it thoroughly, and proceed to air-dry.
Diluted Antiseptic Mouthwash Soak (Alcohol-Free)
A brief soak in an alcohol-free antiseptic mouthwash can also provide an additional layer of sanitization. Alcohol can dry out and potentially damage certain mouthguard materials over time, so alcohol-free is crucial.
Actionable Explanation: If you don’t have cleaning tablets, or as an occasional alternative, you can soak your mouthguard in a diluted alcohol-free antiseptic mouthwash. Dilute the mouthwash with an equal part of water to avoid any potential irritation or residue. Soak for no more than 5-10 minutes.
Concrete Example: You’ve run out of cleaning tablets before a big tournament. As an alternative, pour a small amount of alcohol-free mouthwash into a cup and add an equal amount of water. Soak your mouthguard for 7 minutes, then remove it and rinse meticulously under running water to ensure no mouthwash residue remains.
UV Sanitizers: A Modern Approach
For those looking for a more advanced sanitization method, UV (ultraviolet) sanitizers designed for oral appliances are becoming increasingly popular. These devices use UV-C light to kill bacteria and viruses.
Actionable Explanation: If you invest in a UV sanitizer, simply place your cleaned and dried mouthguard inside the designated compartment, close the lid, and activate the cycle according to the manufacturer’s instructions. These cycles are typically short, ranging from 5-15 minutes. UV sanitizers are particularly useful for peace of mind, offering a chemical-free way to destroy a wide range of microorganisms.
Concrete Example: After every practice, you perform your usual rinse and light soap clean. Before storing, you place your mouthguard in your compact UV sanitizer for a 10-minute cycle. This ensures that any remaining bacteria, even those missed by brushing, are effectively neutralized, offering superior hygiene.
Drying and Storage: Essential for Longevity and Hygiene
Proper drying and storage are just as important as cleaning. A damp mouthguard is an invitation for bacterial and fungal growth, leading to odors, discoloration, and potential health issues.
Air Dry Completely
This is non-negotiable. Putting a damp mouthguard into an enclosed container is the quickest way to cultivate a microbial colony.
Actionable Explanation: After cleaning and rinsing, shake off any excess water and allow your mouthguard to air dry completely before storing it. Place it on a clean, dry surface, away from direct sunlight or extreme heat. A paper towel, a clean counter, or a dedicated drying rack can work well. Ensure there is good air circulation around all surfaces.
Concrete Example: You’ve just washed your mouthguard after soccer practice. Instead of immediately putting it back in its case, place it on a clean paper towel on your bathroom counter. Flip it periodically to ensure all sides are exposed to the air. Wait until it feels completely dry to the touch, which might take an hour or two depending on humidity.
Use a Vented Mouthguard Case
A dedicated case is essential for protecting your mouthguard from physical damage and contamination when not in use. However, the type of case matters.
Actionable Explanation: Always store your completely dry mouthguard in a sturdy, rigid case. Crucially, the case should be vented. Vents allow for air circulation, preventing moisture from becoming trapped and inhibiting bacterial and fungal growth. Avoid sealed, airtight containers, especially if the mouthguard isn’t completely dry.
Concrete Example: After your mouthguard has thoroughly air-dried, place it in its hard plastic case with small ventilation holes. This protects it from being crushed in your gym bag and allows any residual moisture to evaporate, preventing mildew and odor.
Keep the Case Clean
Your mouthguard case can also harbor bacteria if not cleaned regularly.
Actionable Explanation: Periodically wash your mouthguard case with soap and water, just as you would your mouthguard. Allow the case to air dry completely before returning your mouthguard to it. A dirty case negates the benefits of a clean mouthguard.
Concrete Example: Once a week, when you deep clean your mouthguard, also take the time to wash its case with warm soapy water. Use a small brush to get into any crevices. Rinse thoroughly and let the case air dry alongside your mouthguard.
Avoid Extreme Temperatures
Just as direct heat can warp your mouthguard, extreme cold can also affect its material, making it brittle.
Actionable Explanation: Never leave your mouthguard in direct sunlight, on a hot car dashboard, near a radiator, or in boiling water. Similarly, avoid storing it in extremely cold environments, like a freezer. Room temperature storage in a clean, dry place is ideal.
Concrete Example: It’s winter, and you’re leaving for an ice hockey game. Don’t leave your mouthguard in the car overnight where temperatures might drop below freezing. Instead, bring it inside and store it at room temperature in its case.
When to Replace Your Mouthguard: Recognizing the Signs
Even with the best care, mouthguards don’t last forever. Knowing when to replace yours is critical for maintaining optimal protection.
Visible Wear and Tear
This is the most obvious indicator that your mouthguard needs replacing.
Actionable Explanation: Regularly inspect your mouthguard for signs of damage. Look for cracks, tears, holes, thinning spots, or areas where the material appears to be breaking down. Pay particular attention to the occlusal (biting) surface and the edges that fit around your gums. Any significant damage compromises its protective capabilities.
Concrete Example: After a season of intense wrestling, you notice small tears and a general thinning of the material on the biting surface of your mouthguard. The edges also feel rough and are no longer smoothly contoured to your gums. These are clear signs that its shock absorption has been compromised and it’s time for a new one.
Loss of Fit
A properly fitting mouthguard should be snug and stay in place without needing to be held by your teeth. If it starts to feel loose, it’s time for a replacement.
Actionable Explanation: Over time, especially with frequent use, mouthguards can lose their precise fit. The material may soften, or its shape might subtly change due to repeated impact and chewing. If your mouthguard no longer feels secure, shifts when you talk or breathe, or requires you to clench your teeth to keep it in place, its protective function is diminished.
Concrete Example: You used to be able to talk normally with your mouthguard in, but now it feels loose and you have to constantly push it back into place with your tongue. This indicates a loss of fit, and it will no longer effectively cushion impacts.
Odor or Discoloration That Persists
While proper cleaning minimizes odor and discoloration, persistent issues often indicate deeply embedded bacteria or material degradation.
Actionable Explanation: If your mouthguard retains a foul odor even after thorough cleaning and sanitization, or if it has developed persistent yellowing or staining that won’t come off, it’s a strong sign that bacterial colonies have become entrenched in the material, or the material itself is breaking down.
Concrete Example: Despite diligently cleaning your mouthguard daily and using effervescent tablets weekly, it still has a faint, unpleasant smell. Furthermore, it has developed a stubborn yellowish tint that wasn’t there initially. This suggests bacterial colonization deep within the material, making it unhygienic and signaling it’s time to retire it.
General Rule of Thumb
Even if none of the above signs are present, a general guideline is to replace your athletic mouthguard every sports season or at least once a year. For growing adolescents, replacement might be more frequent as their teeth and jaws change.
Actionable Explanation: Make it a habit to factor in mouthguard replacement as part of your annual sports equipment renewal. If you’re playing multiple sports or are a professional athlete, consider a new mouthguard every 6 months. For children and teenagers undergoing orthodontic treatment or significant dental development, consult with your dentist about the appropriate replacement schedule.
Concrete Example: At the beginning of each football season, you automatically budget for and purchase a new mouthguard, even if your old one looks superficially fine. This proactive approach ensures you always have a fresh, optimally protective device. For your teenage son, whose braces were recently removed, you ensure he gets a new custom-fitted mouthguard specifically designed for his post-orthodontic bite.
Advanced Considerations and Common Pitfalls to Avoid
Beyond the basics, a few additional considerations can elevate your mouthguard care and help you avoid common mistakes.
Custom-Fit vs. Boil-and-Bite: Impact on Care
The type of mouthguard you use can subtly influence its care requirements.
Actionable Explanation: Custom-fitted mouthguards, made by a dentist, offer the most precise fit and often use higher-quality, denser materials. This typically makes them more durable and slightly less prone to bacterial absorption compared to boil-and-bite mouthguards, which are softer and more porous. However, all mouthguards require diligent cleaning regardless of their type. The key difference is that a custom guard might withstand slightly more rigorous brushing, while a boil-and-bite might show wear more quickly if scrubbed too harshly.
Concrete Example: You have a custom-fitted mouthguard. While it feels robust, you still use a soft-bristled brush to clean it. You notice that even after years of use, it retains its shape better than the boil-and-bite your friend uses, which started deforming within a few months.
The Dangers of Neglecting Your Mouthguard for “Just a Little While”
It’s easy to think “I’ll clean it later,” but procrastination is the enemy of hygiene.
Actionable Explanation: The longer a mouthguard sits uncleaned after use, the more time bacteria have to multiply and organic matter has to dry and adhere firmly to the surface. This makes subsequent cleaning much more difficult and less effective. Make immediate post-use cleaning a non-negotiable habit.
Concrete Example: You come home exhausted from soccer practice and drop your mouthguard, uncleaned, into your bag, planning to clean it in the morning. By then, the dried saliva and sweat have formed a sticky film, and the mouthguard has developed a faint, unpleasant odor. It takes significantly more effort to clean it properly compared to rinsing it immediately after use.
Avoid Harsh Chemicals and Abrasives
What you don’t use on your mouthguard is as important as what you do.
Actionable Explanation: Steer clear of harsh chemicals like bleach, rubbing alcohol (unless specifically recommended by your dentist for a unique situation, which is rare), or strong household cleaners. These can degrade the mouthguard material, alter its properties, make it brittle, or leave behind toxic residues. Similarly, abrasive cleaning pads or toothpaste can scratch the surface, creating microscopic havens for bacteria.
Concrete Example: Your friend suggests cleaning your mouthguard with a dilute bleach solution to really “disinfect” it. You correctly refuse, knowing that bleach can severely weaken the plastic, leading to early cracking and potentially exposing you to harmful chemicals in your mouth.
The Importance of Hand Washing
While some mouthguards might be technically dishwasher safe, hand washing is almost always preferred and safer.
Actionable Explanation: Dishwashers, especially those with high-temperature cycles, can easily warp or damage mouthguard materials. The detergents used in dishwashers can also be too harsh. Hand washing with mild soap and cold water gives you more control and ensures gentle yet effective cleaning.
Concrete Example: You’re tempted to throw your mouthguard in the dishwasher after a particularly tough game. You remember that the intense heat of the drying cycle could easily melt or deform your custom-fitted mouthguard, so you stick to hand washing it at the sink.
