Hockey mouth guards are a part of a hockey player's equipment. Players wear mouth guards in their mouth, and the guard protects the player's teeth, tongue, and head.
Mouth guards assure that teeth do not grind together, and that the player does not bite their tongue. Mouth guards are a rare piece of equipment in that they protect players from accidentally hurting themselves.
On big checks and collisions, mouth guards can also reduce rates of concussions. Mouth guards do this by providing stabilization to a player's head, and also by helping absorb shock in the head. Concussions are serious injuries in hockey, and the NHL has made many policy changes in an effort to cut down the number of concussions.
There are many different types of mouth guards. Some mouth guards have straps which suspend them on the cage of the hockey helmet, whereas others do not have a strap and must remain in a players mouth.
There are also special mouth guards for hockey players wearing braces, as normal mouth guards may be painful. These special mouthguards are extra soft, and often preferred even by players who do not have braces.
The brands of mouth guards are different from the brands of most other hockey equipment. The most popular brands are Under Armor and Shock Doctor.
Hockey mouth guards can be found at almost any sports equipment store. Mouth guards can cost as little as $1, and as much as $60.
