Before You Start

Check the bite guard for any cracks or wear before cleaning. Do not use hot water, bleach, or harsh chemicals, which can degrade materials. If the device is used with braces or dental work, consult your dentist for compatible cleaners. Time estimates: a quick rinse takes 1–2 minutes; a full cleaning routine takes 5–10 minutes depending on method. Avoid abrasive scrubbers that can scratch the surface.

Step-By-Step: How To Clean A Bite Guard

Rinse the bite guard under cold or lukewarm running water to remove saliva and loose debris.
Gently brush the exterior and interior surfaces with a soft-bristle toothbrush to lift plaque and buildup.
Prepare a cleaning solution using mouthguard cleaning tablets for night guard per package directions, or apply a small amount of antibacterial mouth guard cleaner spray.
Soak the device for the recommended time, typically 5–10 minutes for tablets or as directed by the spray product.
Lightly brush again after soaking to remove any remaining residue, paying attention to crevices and the between-teeth areas of the device.
Rinse thoroughly with clean water to remove all cleaner residues.
Shake off excess water and allow the bite guard to air-dry completely on a clean surface or drying rack.
Store in a clean, ventilated case to prevent moisture buildup and odor.
For periodic deep cleaning, use an ultrasonic cleaner for mouthguard following the manufacturer’s instructions, then rinse and dry.
Inspect the bite guard before next use. If you notice cracks, warping, or persistent odor, discontinue use and consult a dentist.

Always dry completely before storing to prevent bacterial growth.
Label and inspect your cleaning tools to avoid cross-contamination.
If you wear braces or have sensitive gums, verify compatibility with your chosen cleaner.
