Materials Used to Make American Football Mouthguards

American football is a high-impact sport that places significant stress on players' oral structures. To ensure maximum protection, comfort, and performance, mouthguards are crafted from carefully selected materials. These materials must offer excellent shock absorption, durability, flexibility, and a secure fit. The choice of material directly influences the level of protection, comfort during wear, and longevity of the mouthguard.

Thermoplastics: The Foundation of Modern Mouthguards

Thermoplastics are the most widely used materials in American football mouthguards, particularly in boil-and-bite and custom-fitted models. These materials soften when heated and harden upon cooling, allowing them to conform precisely to the shape of a player’s teeth and gums for a snug, personalized fit.

Polyvinyl Chloride (PVC)

PVC is valued for its high stability and strong impact resistance. While less common in premium models today due to advancements in polymer technology, it remains a cost-effective option in entry-level mouthguards. It provides reliable protection against moderate impacts and maintains structural integrity over time.

Ethylene Vinyl Acetate (EVA)

EVA is the gold standard in modern mouthguard materials. Known for its softness, elasticity, and superior energy absorption, EVA effectively cushions blows to the jaw and reduces the risk of concussions and dental injuries. Its flexibility allows for comfortable breathing and speaking, making it ideal for prolonged use during games and practices.

Rubber: Durable and Flexible Protection

Natural rubber is commonly used in generic stock mouthguards due to its inherent elasticity and durability. Rubber provides a good balance between shock absorption and resilience, making it suitable for low- to moderate-contact scenarios such as youth leagues or recreational play.

While rubber adheres well to dental contours and offers decent cushioning, it generally lacks the customization and comfort of thermoplastic models. As a result, it's less favored in professional or high-intensity football settings where optimal fit and advanced protection are critical.

Composite Materials: Advanced Multi-Layer Defense

Professional-grade mouthguards often incorporate composite materials designed to maximize impact dispersion and comfort. These guards typically feature multiple laminated layers, combining different thermoplastics, foams, and rubber compounds.

The layered construction enables graduated shock absorption—softer inner layers cushion the teeth and gums, while rigid outer layers resist deformation. This design not only enhances energy dissipation but also contributes to a lightweight, breathable, and highly durable mouthguard ideal for elite athletes.

Plastic: High-Performance Flexibility and Strength

Plastics, particularly thermoplastic polyurethane (TPU), are increasingly used in high-end mouthguards due to their excellent elasticity, abrasion resistance, and impact strength. TPU maintains its shape under stress and offers superior durability compared to standard thermoplastics.

Its ease of molding makes it perfect for custom-fitted and boil-and-bite applications. Additionally, TPU is resistant to saliva degradation and staining, requiring minimal maintenance while providing long-term hygiene and performance.

Foam: Enhanced Cushioning for Maximum Comfort

Some performance-oriented mouthguards integrate foam padding—typically made from polyether or polyurethane—within the inner lining. These foams are engineered for high energy absorption and are often sandwiched between rigid thermoplastic layers.

This hybrid design delivers a balance of rigidity for protection and softness for comfort. Foam-lined guards are especially beneficial for players with sensitive gums or those seeking enhanced shock mitigation during aggressive play.

Key Considerations in Material Selection

Important: Always choose a mouthguard made from high-quality, sports-approved materials. Inferior materials may fail under impact, increasing the risk of injury. For optimal protection, consider a custom-fitted model made from EVA or TPU by a dental professional. Regular cleaning and inspection for wear are essential to maintain effectiveness.

How To Choose American Football Mouthguards

Ensuring player safety and preventing dental injuries is a top priority for every coach, athletic trainer, and school administrator. In a high-impact sport like American football, mouthguards are essential protective gear—more than just a requirement, they are a critical line of defense against broken teeth, jaw fractures, concussions, and soft tissue damage. Choosing the right mouthguard involves more than just picking the first one off the shelf; it requires understanding the player’s level, fit needs, comfort preferences, and material performance.

Level of Play

The intensity and physical demands of football vary significantly between youth leagues, high school, college, and professional levels. As the level of competition increases, so should the quality and protection level of the mouthguard.
