Why is wearing a mouthguard necessary in lacrosse?

Are White Mouth guards illegal in lacrosse?

Wearing a mouthguard in lacrosse is an essential piece of safety equipment that helps protect players from serious injuries. Mouthguards help to protect the teeth, lips, cheeks, and tongue from impact and can also help reduce the risk of concussions. Mouthguards are required for both men's and women's lacrosse.

Mouthguards are designed to absorb shock and prevent damage to the jaw, teeth, and other parts of the face. They also help to keep players' mouths closed while playing so they can communicate on the field more effectively.

Additionally, studies have shown that athletes wearing mouthguards are 60 times less likely to sustain damage to their teeth than those who don't.

It's crucial for all lacrosse players and goalkeepers - both male and female - to wear a properly fitted mouthguard during games and practices. It's also essential for coaches, officials, and athletic trainers to educate athletes and parents on the importance of wearing a mouthguard.

Lacrosse mouthguard rules

According to NCAA rules and US Youth Lacrosse, all players (including goalies) must wear a mouthguard covering all of their upper teeth. This ensures optimal protection for players' teeth, lips, cheeks, and tongue from potentially damaging impacts during the game.

Additionally, the NCAA requires players to wear visible mouthguards. While NCAA mouthguards offer upper and lower teeth coverage, the NFHS only requires upper teeth coverage.

Athletes of all ages and skill levels need to wear a properly fitted mouthguard during games and practices to stay safe on the field. Not only do these protective devices help keep athletes safe from physical injury, but they also allow them to communicate more effectively while playing.

Types of lacrosse mouthguards

There are several types of lacrosse mouthguards available to protect players from injury. These include:

- Stock mouthguards: Stock mouthguards are the most affordable and basic option. These come pre-formed and tend to be less comfortable and effective than custom-fit mouthguards.

- Boil-and-bite mouthguards: Boil-and-bite mouthguards are made from a thermoplastic material that is heated in boiling water before being bitten into by the player so that it molds to their mouth shape. Although they provide more comfort than stock mouthguards, they may not provide an as accurate or secure fit and may not offer as much protection.

- Custom fit mouthguard: Custom fit mouthguards are designed by a dentist or lab technician specifically for a player's teeth alignment, providing better protection and improved comfort. However, these tend to be more expensive than the other options mentioned above.

Mouthguard violation can lead to severe consequences. Although there are few exceptions, US Youth Lacrosse and NCAA are very strict regarding player safety; a player found not wearing a mouthguard, or wearing one that does not entirely cover their upper teeth, will be penalized and may be subject to disciplinary action.

Here are a few of the mouthguard violations of rules that can occur:

- A mouthguard violation will result in a 1-minute non-releasable equipment personal and technical foul, but not an unsportsmanlike conduct penalty.

- Mouth guards do not need to be attached to the face mask, they can cover all upper or lower teeth and must be worn while playing lacrosse.

- A mouth guard is considered an illegal procedure if it is worn out or altered so that it does not fully protect all of the upper or lower teeth or if the player is biting on the corners (aka "fish-hooking").
