To clean your Night Guard, rinse it with lukewarm water and gently brush it with a soft toothbrush after each use. Avoid using hot water, as some materials can be sensitive to heat and may warp. For deeper cleaning, use a non-alcoholic, non-abrasive soap like hand soap. If you notice any build-up, discolouration, or odour, you can use a generic denture cleaning solution or a cleaning tablet. Regular cleaning helps extend the lifespan of your night guard.
