Whether you wear a mouth guard for sports, teeth grinding, or TMJ relief, one thing is certain: keeping it clean is just as important as wearing it. A mouth guard that isn’t properly cared for can collect bacteria, plaque, and odors leading to bad breath, gum irritation, and even oral infections.
So, how do I clean my mouth guard the right way? And what’s the best way to clean a mouth guard without damaging it?
This guide covers everything you need to know about mouth guard cleaner options, daily and deep-cleaning practices, and how to keep your guard (and your mouth) fresh and healthy.
Mouth guards are designed to shield your teeth but they’re also exposed to everything that lives in your mouth: bacteria, food particles, and saliva. If not cleaned properly, they can become a source of contamination, leading to:
In short, your mouth guard should never be an afterthought. It’s part of your overall oral hygiene routine and it needs regular attention.
The best way to clean a mouth guard starts with daily maintenance. Here’s what we recommend after each use:
Avoid hot water, which can warp the plastic. A simple rinse helps remove debris and saliva.
Use a dedicated toothbrush (not the one you use for your teeth) and non-abrasive soap. Gently scrub all surfaces.
Toothpaste with whitening agents or abrasives can damage the material over time.
Moisture breeds bacteria. Always let your guard dry completely before placing it in its case.
Store your guard in a clean, ventilated case ideally one that you rinse weekly.
This routine takes only a couple of minutes but makes a huge difference in maintaining the safety and quality of your guard.
Even with daily care, your guard should be deep-cleaned at least once or twice a week. So, how do I clean my mouth guard more thoroughly?
Here Are the Most Effective Deep-Cleaning Options:
Add a few drops of clear, unscented antibacterial soap to a cup of lukewarm water. Let your mouth guard soak for 10–15 minutes, then rinse thoroughly and air dry.
Effervescent tablets (like those for dentures or retainers) are safe for most guards and help remove buildup and odor. Let it soak as directed usually 5 to 10 minutes.
