4mm – This is the correct thickness of protection for anybody under the age of 16 and also for sports where the head is NOT in direct contact.
5mm – We recommend a 5mm mouthguard for athletes where the sport is potentially high impact (such as Hockey) or where the head IS in direct contact (ie boxing, MMA).
Adult - This kit will include a medium & large tray
Junior - This kit will include a medium & small tray
Please choose the size appropriate for the person that will be wearing the mouthguard.
