Which is a recommended mouthguard care practice?

• A. Clean the mouth guard with a mild antimicrobial agent and rinse it thoroughly in tepid water both before and after use
• B. Store the mouth guard in a metal container
• C. Examine the mouth guard daily for fit only after a week
• D. Replace the mouth guard only after several years

Answer: (A)

Maintaining mouthguard hygiene and material integrity is essential for both comfort and protection. The best practice is to clean the mouthguard with a mild antimicrobial agent and rinse thoroughly in tepid water before and after use because this helps reduce bacteria, plaque, and odor from saliva and food particles that contact the guard. A mild antimicrobial does the job without harsh chemicals that could irritate tissues or degrade the material, and tepid water avoids heat that could warp or distort the guard. Cleaning before use minimizes contamination from handling, while cleaning after use ensures the guard is free of residues and can dry properly before storage. Storing the mouthguard in a metal container can promote corrosion and bacterial growth, so it’s not advised. Checking fit daily is more comprehensive than needed and waiting too long to assess wear can miss damage, and replacing only after years ignores wear and loss of protective function.
