Mouth guards in sports protect more than teeth

With sports-related concussions on the rise, especially in children and adolescents, a parent’s natural first instinct is to seek out the most technologically advanced head gear. And though newer helmets available with cutting edge foam inserts and titanium face cages can go a long way toward preventing mouth and tooth injuries, an important piece of equipment is often used improperly, or left out completely – the trusty mouth guard.

How They Work

Obviously high-impact sports like hockey and football carry the highest concussion risk to players, but in truth all athletes in any contact sport should wear a mouth guard. Granted, solid proof of the benefits of mouth guard use in sports is lacking, but it is believed that at a moment of impact, a player clenches their  jaw muscles around the mouth guard which in turn stabilizes the skull and neck. Also, a properly fitted mouth guard creates a cushioning pocket of air between the jaw bone and the point at which the jaw connects to the skull, lessening the severity of injury from an upper-cut-like impact to the jaw.

Make it Count

For the most protection, all teeth must be entirely covered including the back molars. Many children complain of a gag reflex which leads parents to trim the posterior of the guard. This is not recommended by dentists and may actually cause a higher risk of a concussive injury. Instead, buy a “boil and bite” mouth guard and have a dentist adjust the bite and posterior thickness as it molds. Or better yet, have a dentist make a custom mouth guard. Both options keep the guard molded tightly to the back teeth and prevents excess material from protruding into the throat. Also have a dentist balance “boil and bite” or off-the-shelf products to the wearer’s bite before first wear. This will ensure all force of impact is distributed evenly across the entire jaw.
