Shock Doctor "Gel Max" Mouthguard
"The Shock Doctor Youth Gel Max strapless mouthguard is the first mouthguard designed specifically for use with braces."
"Mouthguards, also called mouth protectors, help cushion a blow to the face, minimizing the risk of broken teeth and injuries to your lips, tongue, face or jaw."
The ADA, states that athletes are 60 times more likely to damage their teeth if they don't wear a mouth guard. (American Dental Association)
So called, "off the shelf" mouth guards purchased in a drug or sporting goods store are least effective, come in limited sizes, and do not have a "fit adjustment for the athlete's unique mouth shape and size."
The cost of shipping will depend on the quantity, weight, dimensions, and the destination of the parcels.
