Mouthguards are best kept clean by rinsing under cold water after use. They may be brushed very lightly with soapy water or a small amount of toothpaste.
They should be stored in the provided plastic container and should be kept away from heat and sunlight.
Do not store your mouthguard on the mould of your teeth that was returned to you when you collected your mouthguard. Store the mould in a safe place at home.
