A mouth guard is a protective oral appliance, whether used for sports, to prevent teeth grinding, or as an orthodontic retainer. These devices spend time in an environment rich with saliva, bacteria, and microscopic food particles. Without consistent and proper cleaning, a mouth guard can quickly become a haven for microorganisms, leading to odor, potential oral infections, and a shortened lifespan. Maintaining cleanliness is non-negotiable for protecting both your investment and your oral health.
Immediate Care After Use
The first step in daily maintenance is immediate action after removing the guard. Rinse it thoroughly under cool or lukewarm running water to wash away loose debris and saliva before they dry and adhere to the material.
Next, physically clean the surface using a soft-bristled toothbrush dedicated solely for this purpose. Use a small amount of mild, non-abrasive soap, such as hand soap or dish soap, to gently scrub all surfaces, including the grooves. Dentists advise against using regular toothpaste because abrasive particles can scratch the surface, creating spaces where bacteria can hide.
After scrubbing, rinse the mouth guard again under cool water to ensure all soap residue is removed. A thorough rinse prevents lingering soap from causing an unpleasant taste or irritating oral tissues upon next use. This daily routine removes the bulk of collected matter, preparing the guard for air-drying before storage.
Methods for Deep Cleaning
Periodic deep cleaning is necessary to sanitize the guard and eliminate bacteria that daily brushing cannot reach. These sanitization soaks should be performed weekly or bi-weekly. One common method uses non-abrasive denture cleaning tablets, following the manufacturer’s instructions for soaking time, typically 15 to 30 minutes.
Alternatively, prepare a diluted solution using common household agents. A mixture of one part white vinegar to three parts water provides an acidic environment that helps disinfect and break down mineral deposits. Another effective option is equal parts 3% hydrogen peroxide and water, which serves as an excellent disinfectant and aids in stain removal. Soak the mouth guard in these solutions for no more than 30 minutes to prevent material degradation.
After the soak, rinse the mouth guard extensively with plain cool water immediately. This final, thorough rinse removes any residual cleaning agents, preventing chemical irritation or an unpleasant taste when you next wear the device.
Storage and Handling Rules
Proper storage is crucial for maintaining the guard’s integrity and hygiene. After cleaning and rinsing, the mouth guard must air-dry completely before being stored. Placing a damp guard into a closed container creates a warm, moist environment ideal for the rapid growth of mold and bacteria.
The guard should be kept in a clean, sturdy storage case that has ventilation holes to facilitate complete drying. Keep the mouth guard away from all sources of excessive heat, including hot water, direct sunlight, or a hot car. Thermoplastic materials can warp or lose their custom fit when exposed to high temperatures.
Strictly avoid cleaning or soaking your mouth guard in harsh household chemicals, such as bleach, concentrated alcohol-based mouthwashes, or abrasive cleaners. These strong agents can damage the material, compromising the fit and surface texture. Regularly cleaning the storage case itself with soap and water prevents the transfer of germs back onto the clean guard.
