The importance of a properly fitting mouthguard in sports

Triple layered mouthguard

Mouthguards are a must-have for contact sports, but their fit is super important.

When it comes to contact sports and high-impact activities, mouthguards are an absolute necessity. They provide crucial protection for athletes, but there’s a catch: a poorly fitting mouthguard can spell trouble not only for performance but also for oral health. In this blog post, we’ll explore the potential issues that can arise from wearing a poorly fitting mouthguard, from injuries to discomfort, breathing and communication difficulties.


First and foremost, the primary purpose of a mouthguard is to protect. A poorly fitting mouthguard simply won’t protect you as it should. To effectively shield against impacts, a mouthguard needs to securely stay in place. When it doesn’t, impacts to the face or head can move or even dislodge the mouthguard which can lead to dental injuries i.e broken, chipped or avulsed teeth (knocked out) and soft tissue damage i.e cuts and bruising to the cheeks, lips and tongue.


Imagine focusing on your game while trying to deal with the movement, discomfort and pain caused by your mouthguard. Poorly fitting mouthguards are often bulky and uncomfortable which can easily distract players enough to affect their performance and discourage them from wearing them.

Difficulty in breathing

For sportspeople engaged in high-intensity activities that demand a lot of energy and oxygen intake, breathing is non-negotiable. However, a mouthguard that doesn’t fit properly can move and interfere with that.

Difficulty in communicating

Communication is key in sports, whether it’s coordinating with teammates, receiving instructions from coaches, or signalling to umpires. A poorly fitting or bulky mouthguard can make it difficult to talk making it challenging for the wearer to convey instructions, or call play.

Choosing the right mouthguard

To avoid the potential pitfalls associated with poorly fitting mouthguards, athletes should prioritise 3 main components – secure fit, comfort and protection.

In conclusion

Wearing a mouthguard is an essential safeguard for athletes, but wearing one that doesn’t fit well can have serious consequences. It’s crucial to invest in a mouthguard like the Neomorph Mouthguard, that fits securely to minimise the risks of injuries, discomfort, interference with breathing and communication barriers.
