Are the cheap boil & bite gumshields from the sportshop just as good?
Definitely not! Just ask the British Dental Association, Rugby Football League Association, British Boxing council, English Hockey Association, Rugby Football Union just to name a few. They emphatically recommend a custom fitted gumshield should be part of your sports kit. Boil & Bite gumshields should be avoided. They offer very low quality protection, they are ill fitting, can easily be dislodged and could present a choking hazard.
