Football players wear mouthguards primarily for dental protection, shielding their teeth, gums, and jaw from the severe forces encountered during play. Can a mouthguard prevent concussions? While not their primary purpose, mouthguards can offer some secondary benefits that may indirectly reduce concussion severity by stabilizing the jaw.
The gridiron is a battlefield of collisions, tackles, and high-speed movements. In this intense environment, injuries are an unfortunate reality. Among the most vulnerable areas of the body are the mouth and teeth. This is precisely why mouthguards are not just recommended, but often a mandatory piece of protective equipment for football players at all levels. They are a critical line of defense against a wide array of oral injuries, from minor chips to devastating tooth loss.

The Science Behind Mouthguard Protection
At its core, a mouthguard functions as a shock absorber. It’s designed to distribute and absorb the force of impacts, preventing it from directly damaging the teeth and surrounding oral structures. This simple yet ingenious device plays a vital role in impact absorption.
Preventing Devastating Dental Damage
The teeth in football are constantly at risk. A stray elbow, a helmet to the face, or even a forceful clash with another player can result in catastrophic damage. This includes:
- Chipped or Broken Teeth: These are common injuries, often occurring when teeth directly impact each other or an opponent’s equipment.
- Knocked-Out Teeth (Avulsions): These are severe injuries requiring immediate attention and can lead to lifelong dental issues and significant costs.
- Dislodged Teeth: Teeth can be pushed out of their sockets or displaced within the jawbone, requiring complex dental procedures.
- Root Fractures: The roots of the teeth can fracture, even if the crown appears intact, leading to pain and eventual tooth loss.
A well-fitted mouthguard acts as a barrier, cushioning these blows and significantly reducing the likelihood and severity of such tooth damage.
Safeguarding the Jaw and Soft Tissues
Beyond the teeth, mouthguards offer protection to the entire oral cavity.
Protecting Against Jaw Fractures
The lower jaw (mandible) is particularly vulnerable in football. When a strong force is applied to the chin or jaw, it can transmit through the teeth and cause a jaw fracture. A mouthguard can help spread this force across more teeth and the jawbone, making a fracture less likely. By keeping the teeth from clenching tightly during impact, it also prevents the transmission of shock directly to the jaw joint.
Preventing Lacerations and Soft Tissue Injuries
The sharp edges of teeth can easily cause cuts and lacerations to the lips, tongue, and inner cheeks during a collision. A mouthguard covers these sharp edges, preventing lacerations and other soft tissue damage. It acts as a buffer, keeping the soft tissues from being pinched between the teeth and the jaw or cheek.
The Role of Mouthguards in Concussion Prevention and Management
The debate around whether mouthguards can prevent concussions is complex. While their primary function is not concussion prevention, they can play an indirect role.
Stabilizing the Jaw and Reducing Impact Transmission
When a player suffers a blow to the jaw, it can cause them to involuntarily clench their teeth. This clenching can transmit a significant portion of the impact force directly to the base of the skull and brain. A mouthguard, by maintaining a slight separation between the upper and lower teeth, can prevent this forceful clenching. This slight separation can:
- Reduce the direct transmission of force: By keeping the teeth from grinding, the impact force is less likely to travel directly up the skull.
- Help the jaw absorb some of the impact: The mouthguard material itself can absorb some of the energy.
While this doesn’t eliminate the risk of concussion, it is believed that this jaw stabilization can potentially lessen the severity of some head impacts. This is a key area of research within sports dentistry.
Mouthguards and Brain Injury Mitigation
It’s important to emphasize that mouthguards are not a cure-all for concussions. They are not designed to absorb the direct forces that cause the brain to move within the skull. However, any measure that can reduce the overall impact force transmitted to the head is considered beneficial. This is why many athletic organizations, even those primarily focused on player safety, mandate their use.
Types of Mouthguards: Customization for Optimal Protection
Not all mouthguards are created equal. The effectiveness of a mouthguard heavily depends on its type and how well it fits.
Stock Mouthguards
- Description: These are the most basic and least expensive. They are pre-formed and available in general sizes (small, medium, large).
- Pros: Cheap and readily available.
- Cons: Poor fit, bulky, difficult to speak and breathe with, less effective at providing protection. They often require the user to clench their teeth to keep them in place, which can reduce their protective benefits.
Boil-and-Bite Mouthguards
- Description: These mouthguards are softened in hot water and then molded to the wearer’s teeth by biting down.
- Pros: Relatively inexpensive, offer a better fit than stock mouthguards, and are widely available.
- Cons: Fit is still not as precise as custom-made guards. The molding process can sometimes be tricky, and they can become less effective if not molded correctly. They can also be bulky.
Custom-Mouthguards
- Description: These are professionally made by a dentist or dental technician. They are created from an impression of the player’s teeth, ensuring a perfect, snug fit.
- Pros: Best possible fit, most comfortable, allow for easier breathing and speaking, superior impact absorption, and offer the highest level of dental protection. They stay securely in place without the need for excessive clenching.
- Cons: Most expensive option.
For serious athletes, especially those in high-impact sports like football, a custom-made mouthguard is the gold standard for protection and comfort.
Factors Affecting Mouthguard Effectiveness
Several factors contribute to how well a mouthguard protects a player:
- Fit: A mouthguard that is too loose will not stay in place and offers minimal protection. One that is too tight can be uncomfortable and impede breathing.
- Material: The material needs to be resilient enough to absorb impact without deforming permanently.
- Coverage: The mouthguard must cover all the teeth in the arch it is designed for, including the biting surfaces and at least half of the tooth surfaces.
- Thickness: Adequate thickness is crucial for impact absorption. Thicker guards generally offer more protection, but also can be more cumbersome.
The Impact of Mouthguards on Athletic Performance
While comfort and protection are paramount, a well-designed mouthguard should not hinder athletic performance.
Breathing and Communication
A poorly fitting mouthguard can make breathing difficult, especially during intense physical exertion. This can lead to fatigue and reduced stamina. Similarly, if a mouthguard is too bulky or interferes with speech, it can make communication on the field challenging, which is crucial for team coordination and strategy.
Custom-made mouthguards are specifically designed to be as streamlined as possible, allowing for unobstructed breathing and clear communication. This ensures that the player can focus on their game without distraction.
Comfort and Focus
A comfortable mouthguard allows a player to concentrate on their performance rather than on adjusting or dealing with discomfort. When a mouthguard fits properly and feels secure, it becomes an almost unnoticeable piece of protective equipment, allowing the athlete to perform at their best.
The Importance of Dental Consultation
The field of sports dentistry plays a crucial role in educating athletes, parents, and coaches about the importance of mouthguards. Dentists are experts in oral anatomy and can:
- Assess individual needs: They can determine the best type of mouthguard for a particular sport and player.
- Take accurate impressions: For custom mouthguards, precise impressions are vital for a perfect fit.
- Fabricate high-quality mouthguards: They ensure the mouthguards are made from appropriate materials and meet safety standards.
- Provide guidance on care and maintenance: Proper care ensures the mouthguard remains hygienic and effective.
Many dental professionals offer services specifically for athletes, creating custom mouthguards for a range of sports.
Mouthguard Usage: Rules and Regulations
The mandatory use of mouthguards in football varies by league and governing body. However, the trend is towards universal adoption due to the clear evidence of their protective benefits.
- High School Football: In most states and athletic associations, mouthguards are mandatory for all players.
- College Football: Mouthguards are also a standard requirement in collegiate football.
- Professional Football (NFL): While not universally mandated for every position in the past, the NFL strongly recommends and effectively requires mouthguards for many players due to their dental protection benefits. There’s a growing emphasis on their use across all positions.
These regulations highlight the recognized importance of mouthguards in reducing oral injuries and potentially mitigating the impact of head trauma.
Caring for Your Mouthguard
To ensure your mouthguard remains effective and hygienic, proper care is essential.
Cleaning
- Rinse the mouthguard with cool water after each use.
- Brush it gently with a soft toothbrush and non-abrasive toothpaste or mild soap.
- Avoid using hot water, as it can warp the mouthguard.
Storage
- Store the mouthguard in a well-ventilated case to allow it to dry completely. This prevents bacterial growth.
- Keep the case clean and dry.
- Avoid exposing the mouthguard to excessive heat, such as leaving it in direct sunlight or in a hot car.
Replacement
Mouthguards, especially boil-and-bite types, can wear out over time. They should be replaced if they show signs of damage, become loose, or if the player has had significant dental work done (e.g., braces, new fillings). Regular dental check-ups can also help determine when a mouthguard needs replacing.
Common Misconceptions About Mouthguards
Despite their proven benefits, some misconceptions persist:
- “Mouthguards only protect teeth”: As discussed, they also protect the jaw and soft tissues and can indirectly help with concussion management.
- “If it’s not mandatory, I don’t need it”: The absence of a rule doesn’t negate the risk of injury. Dental protection is crucial regardless of regulations.
- “My teeth aren’t that bad, so I’ll be fine”: Even perfectly healthy teeth are susceptible to damage from the forces in football.
- “Boil-and-bite guards are good enough”: While better than nothing, they cannot match the fit and protection of custom guards.
The Future of Mouthguard Technology
Research and development in sports dentistry continue to advance mouthguard technology. Future innovations may include:
- Integrated sensors: Mouthguards with sensors that can measure impact forces and potentially detect the onset of a concussion.
- Improved materials: Development of lighter, more durable, and more shock-absorbent materials.
- Personalized designs: Enhanced customization based on individual biomechanics and specific sport demands.
These advancements promise even greater protection and more detailed insights into the mechanics of sports-related injuries.
