If you wear a night guard to protect your teeth from grinding or to help with TMJ symptoms, you know how important this little device is for your oral health. But are you giving it the proper care it needs?
Just like your teeth, your mouth guard can accumulate bacteria, plaque, and unpleasant odors if it’s not cleaned regularly. Knowing how to clean a mouth guard correctly is essential for keeping it hygienic, effective, and long-lasting.
Many people are unsure about the best way to clean their night guard. Can you use toothpaste? Is hot water safe? At Bella Dental, we want to ensure our patients get the most out of their custom-fit oral appliances. That’s why we’ve put together this comprehensive guide on how to clean your mouth guard like a pro.
Follow these simple steps to keep your night guard in pristine condition.
Your mouth is home to millions of bacteria. When you wear your night guard, these microorganisms, along with saliva and plaque, transfer onto the appliance.
If not cleaned properly, this buildup can lead to several problems:
Regular cleaning is a simple but crucial step in maintaining both your oral health and the integrity of your night guard.
The most important part of keeping your mouth guard clean is to establish a consistent daily routine. This should be done every morning after you take the guard out of your mouth.
As soon as you remove your night guard, rinse it thoroughly with cool or lukewarm water. This will wash away any loose plaque, saliva, and debris before it has a chance to dry and harden.
Pro Tip: Avoid using hot water, as it can warp the material of your custom night guard, causing it to lose its precise fit.
After rinsing, use a soft-bristled toothbrush (separate from your regular toothbrush) to gently brush all surfaces of the mouth guard. You can use a non-abrasive, antibacterial soap or a specialized night guard cleaner.
Avoid using regular toothpaste, as it can be abrasive and create microscopic scratches on the surface of the guard. These tiny scratches can become a haven for bacteria to hide and multiply.
Once you’ve finished brushing, rinse the mouth guard thoroughly one more time to remove any soap residue. Then, it is crucial to let it air dry completely on a clean surface before storing it.
Storing a damp mouth guard creates a moist environment that encourages bacterial growth. You can pat it dry with a clean towel or simply leave it out to air dry.
In addition to your daily cleaning routine, it’s a good idea to give your night guard a deeper clean at least once a week. This will help to remove any stubborn buildup and keep it sanitized.
Here are a few effective deep-cleaning methods you can use.
Hydrogen peroxide is an excellent disinfectant that can kill bacteria and help to whiten a discolored mouth guard.
Baking soda is a natural and gentle cleaner that can help to neutralize odors and remove stains.
There are many over-the-counter cleaning tablets and solutions specifically designed for oral appliances like night guards and retainers. These are a convenient and effective option for deep cleaning.
Simply follow the instructions on the product packaging, which usually involve dissolving a tablet in water and soaking the mouth guard for a specified amount of time.
How you store your night guard is just as important as how you clean it. Proper storage protects it from damage and keeps it clean between uses.
Always store your mouth guard in the protective case provided by your dentist. This case should be clean and ventilated to allow for air circulation and prevent moisture buildup.
Make sure to clean the case itself regularly with soap and water to prevent it from becoming a source of bacteria.
To protect your investment and ensure your night guard lasts as long as possible, there are a few things you should never use to clean it:
