http://www.guardkit.com/en/ Your gum shield individually produced in our dental laboratory. http://www.guardkit.com/en/ I used to pat the top of the bat handle to make sure the rubber wasn't sticking out. As for the gum, well, a dentist once tried to tell me to wear a gum shield. But for me going out to bat without chewing gum was like going out without a box. And you can't chew gum with a gum shield. http://www.guardkit.com/en/products.asp?cat=11 The gum shield is the most important piece of equipment a rugby player should own. http://www.guardkit.com/en/products.asp?cat=13 Gumshields are very important to use, even when not sparring , they help you to learn how to breathe out of your nose. This is important because if you don't know how to, you may open our mouth during sparring due to being breathless, this is a dangerous position to be in because a punch to your chin at this time could cause you to get knocked out. So next time you are training on the heavy bag or shadow boxing, keep the gumshield in, and bite on it at all times, try not to get into the habit of not biting it. http://www.guardkit.com/en/toothinjury.asp If you play any kind of physical sport, at school or in a club, there's a risk of dental damage. http://www.guardkit.com/en/products.asp?cat=13 All boxers must wear a gum shield, cup protector, bandages on the hands and an AIBA approved and stamped head guard, when competing http://www.guardkit.com/en/products.asp?cat=12 supplied by you are shin guards and a gum shield (just to be safe)
