Because it is within your mouth, your sporting mouthguard gathers and traps plaque and bacteria over time. After each usage and before putting your mouthguard into its storage case, it is advised that you rinse it under cool water. Wash then leave your mouthguard in cool water with an antibacterial cleaning tablet for around 20 minutes. After that, gently brush the mouthguard with a toothbrush and thoroughly rinse with cool water. Your guard’s fit will be distorted by hot water. While the mouthguard is soaking, properly wash and dry the storage container to avoid bacterial growth.
