Do Mouthguards Improve Athletic Performance? Exploring the Connection

Updated: Sep 19, 2023


When it comes to athletic performance, athletes are constantly seeking ways to gain an edge over their competition. From rigorous training regimes to cutting-edge equipment, every advantage counts. One piece of equipment that has gained significant attention in recent years is the mouthguard. But the question remains: do mouthguards improve athletic performance? In this blog, we will explore the connection between mouthguards and athletic performance, examining the scientific evidence and shedding light on the potential benefits they may provide.

Protection and Injury Prevention

While the primary purpose of a mouthguard is to protect the teeth and jaw from injuries, its impact on athletic performance goes beyond safeguarding oral health. Mouthguards act as a shock absorber, reducing the force of impact to the mouth and jaw during high-intensity physical activities. By minimizing the risk of dental fractures, jaw dislocations, and soft tissue injuries, mouthguards allow athletes to stay focused on their performance without the worry of potential injuries. In this way, mouthguards indirectly contribute to enhanced athletic performance by promoting confidence, reducing distractions, and maintaining an athlete's mental state during gameplay.

Enhanced Muscular Performance

The connection between mouthguards and athletic performance goes beyond protection. Some research suggests that mouthguards can positively impact an athlete's muscular performance. According to studies, wearing a properly fitted mouthguard may help improve muscular strength and endurance. The theory behind this is that the mouthguard's design and fit can influence the alignment of the jaw, potentially optimizing muscle function and improving overall body mechanics. While more research is needed to fully understand this connection, initial findings indicate a potential link between mouthguards and enhanced muscular performance.

Respiratory Efficiency and Oxygen Intake

Another factor that may contribute to improved athletic performance is respiratory efficiency. Some mouthguards are designed to promote proper alignment of the jaw and open the airway, potentially increasing the amount of oxygen an athlete can take in during physical exertion. Adequate oxygen intake is crucial for endurance, stamina, and overall athletic performance. By ensuring optimal airflow, mouthguards could potentially help athletes perform at their best by reducing the strain on the respiratory system and enhancing oxygen delivery to the muscles.

Psychological Benefits

Athletic performance is not solely determined by physical factors. The mental aspect plays a significant role as well. Mouthguards can offer psychological benefits that impact an athlete's performance. By providing a sense of security and reducing anxiety about potential dental injuries, mouthguards can enhance an athlete's focus, concentration, and overall mental state. With fewer distractions and worries, athletes can channel their energy into their performance, leading to improved results.


While the scientific research is still evolving, there is evidence to suggest that mouthguards can have a positive impact on athletic performance. Beyond their primary function of protecting the teeth and jaw, mouthguards may enhance muscular performance, improve respiratory efficiency, and provide psychological benefits. However, it's important to note that the effectiveness of mouthguards can vary depending on factors such as proper fit, quality, and individual athlete characteristics.

Ultimately, athletes should consult with their coaches, trainers, and dental professionals to determine the most suitable mouthguard for their specific needs. By considering the potential benefits and exploring the connection between mouthguards and athletic performance, athletes can make informed decisions about incorporating this piece of equipment into their training and competition routines. With the right mouthguard, athletes can focus on what they do best – giving their best performance on the field, court, or track.
