Why Every Athlete Needs to Understand the Helmet with Mouthguard Combination
Using a helmet with mouthguard together is one of the most effective ways to protect yourself from serious injury in contact sports. Here’s the short answer:
- Helmets reduce head injury risk by up to 85% in recreational sports
- Mouthguards can prevent more than 200,000 oral injuries per year, according to the American Dental Association
- Wearing both together protects against dental injuries, jaw trauma, and potentially reduces concussion risk
- Proper placement matters — a mouthguard only works when worn correctly, not clipped to the outside of your helmet
These two pieces of equipment do different jobs. A helmet absorbs impact to your skull. A mouthguard protects your teeth, jaw, and soft tissue — and may help cushion the force that travels up to your brain.
Yet in June 2026, the conversation around mouthguard use is more interesting than ever. Detroit Lions safety Brian Branch became a talking point when he revealed he wears his mouthguard on top of his helmet rather than in his mouth — mainly because it affects his breathing during long drives. He’s not alone in that habit, and it raises real questions about safety, comfort, and performance.
This guide covers everything you need to know: the science, the equipment options, the rules, and how to get the best protection possible.
I’m Dr. Janne Lynch, a cosmetic and general dentist with years of experience helping athletes and families in Arizona understand how oral protection connects to overall health. At AZ Dentist Scottsdale, AZ Dentist Glendale, AZ Dentist Sun City, and AZ Dentist Sedona, I see the dental damage that can happen when a proper helmet with mouthguard setup is overlooked — and I’m here to help you avoid that.
The Safety Science Behind a Helmet with Mouthguard
When we look at sports safety from a clinical perspective, we have to look at the head and mouth as an integrated system. Many athletes think that if they are wearing a top-of-the-line helmet, their teeth and jaws are automatically safe. This is a dangerous misconception.
The American Dental Association estimates that a full third of all dental injuries are sports-related. This is a staggering statistic, but there is a simple solution: the use of a mouthguard can prevent more than 200,000 oral injuries to the mouth each year. When an athlete experiences an impact to the face, the force has to go somewhere. Without a mouthguard, that energy is transferred directly to the teeth, which can lead to fractures, luxations (loosened teeth), or complete avulsions (knocked-out teeth).
But the benefits of a helmet with mouthguard setup go beyond protecting your smile. There is ongoing scientific discussion about the role mouthguards play in reducing concussion risk. In a study of 1,033 NHL athletes, the rate of concussion was found to be 1.42 times greater in individuals who did not wear mouthguards compared to those who did. While this specific finding was not statistically significant, it points to a protective trend that sports medicine professionals take very seriously.
To understand why, we have to look at how concussions happen. Concussions are typically caused by rotational acceleration rather than linear acceleration alone. When an athlete takes a hard hit to the chin, the lower jaw (mandible) is driven violently upward and backward into the base of the skull. This sudden movement causes rotational forces in the brain, leading to diffuse axonal injury—the primary mechanism behind a concussion.
A high-quality mouthguard acts as a shock absorber. By separating the mandible from the maxilla and cushioning the jaw joint (temporomandibular joint, or TMJ), it helps disperse the upward kinetic energy of a lower-jaw impact.
Helmets, on the other hand, are excellent at reducing catastrophic head injuries, such as skull fractures and subdural hematomas. In fact, helmets have been estimated to reduce head injury risk by 85 percent in recreational sports. In American football, helmet designs have evolved significantly to meet strict National Operating Committee on Standards for Athletic Equipment (NOCSAE) guidelines. For example, in one study, athletes wearing the Riddell Revolution helmet had a 5.3% concussion rate compared to 7.6% for those wearing standard helmets, representing a 31% decreased relative risk.
However, even the most advanced helmet cannot protect the teeth and jaw from direct impact or prevent the jaw-to-skull forces that contribute to concussions. This is why pairing a certified helmet with a properly fitted mouthguard is non-negotiable.

On-Field Performance: Breathing, Comfort, and the Brian Branch Trend
If the safety science is so clear, why do we see professional athletes taking shortcuts with their gear? The answer usually comes down to three things: breathing, comfort, and performance.
Take Detroit Lions defensive back Brian Branch, for example. Branch has become incredibly popular on defensive coordinator Aaron Glenn’s defense because of his hard hits and instinctual play. Yet, fans and analysts quickly noticed a quirky habit: Branch frequently wears his bright green mouthguard on top of his helmet rather than inside his mouth.
When asked about this decision, Branch explained that he has worn the green mouthpiece on his helmet as a tradition since his college days. More importantly, he noted that he struggles to breathe comfortably with the mouthguard in his mouth, especially during long, exhausting defensive drives. While he briefly considered wearing it traditionally before playing against a run-heavy team, he ultimately decided against it.
This highlight-reel habit highlights a major challenge for athletes at all levels. When you are sprinting down the field, your body demands maximum oxygen intake. If a mouthguard is bulky, poorly fitted, or blocks the airway, an athlete will naturally want to spit it out or clip it to their helmet.
Fortunately, mouthguard technology has come a long way. Modern manufacturers have developed high-airflow models specifically designed to address these breathing concerns. For example, the 3D Mask Oxygen Football Mouthguard | Switch Strap, Strapless, Braces Safe features a patented SCUBA-inspired breathing channel. This design provides the largest breathing channel on the market, allowing athletes to get maximum oxygen to their muscles without sacrificing lip and teeth protection. Another excellent option is the Oxygen 3D Apex Predator Football Mouthguard, which combines this high-airflow platform with a striking, color-shifting iridescent finish.
For players who prefer a traditional lip-shield design that attaches directly to the helmet facemask, options like the Thunder Bolt Lip Guard – Shock Doctor provide an instant, no-boil fit with a high-flow breathing channel. These lip guards feature heavy-duty tethers that keep the mouthguard securely attached to the helmet, making it easy to pop out during huddles and pop back in before the snap.
Comparing Mouthguard Types: Custom-Fitted vs. Boil-and-Bite
Choosing the right type of mouthguard is just as important as choosing the right helmet. Let’s compare the primary options available to athletes today:
| Feature | Custom-Fitted Mouthguards | Boil-and-Bite Mouthguards | Ready-to-Wear (No-Boil) |
|---|---|---|---|
| Fit & Comfort | Exceptional; made from precise dental impressions | Good; molds to teeth after heating | Moderate; generic fit |
| Airflow & Speech | Maximum; thin but highly protective | Moderate; can be bulky | High (if designed with breathing channels) |
| Braces Compatibility | Excellent (can be adjusted by your dentist) | Good (specifically designated models) | Excellent (fits loosely over brackets) |
| Dental Warranty | Varies by provider | Often included (up to $35,000) | Often included (up to $5,000) |
| Cost | Higher investment | Affordable | Highly budget-friendly |
Custom-Fitted Mouthguards
As a dentist, I always recommend a custom-made mouthguard if you want the absolute best in protection, comfort, and speech. We make these in our offices—whether you visit us at AZ Dentist Glendale, AZ Dentist Scottsdale, or AZ Dentist Sedona—by taking a highly accurate impression of your teeth.
Because they are molded precisely to your unique dental anatomy, they stay in place without you needing to clench your jaw. This makes it incredibly easy to breathe and communicate plays on the field. While they are a larger investment, they offer unmatched durability and protection.

Boil-and-Bite Mouthguards
Boil-and-bite options offer a solid middle ground. These guards are made from thermoplastic materials that soften when placed in hot water. Once softened, the athlete bites down on the guard to mold it to their teeth.
Products like the Fang Football Mouthguard 2-Pack | Battle Sports use advanced composite materials that can be re-boiled and re-molded multiple times. This is incredibly useful for growing athletes or those undergoing orthodontic treatment, as the guard can be adjusted as the teeth move. Many of these retail packages also come with substantial dental warranties—sometimes up to $35,000—to cover dental work if an injury occurs while wearing the guard.
Ready-to-Wear (No-Boil) Mouthguards
If you need protection straight out of the box, no-boil mouthguards are a highly convenient choice. The Speed XL Football Mouthguard | Battle Sports and the CBFW Speed Football Mouthguard | Battle Sports are designed with integrated bite pads and thick, connected helmet straps. These models do not require any molding; they rely on flexible, high-impact composites to cushion the jaw and protect the lips immediately. They are also highly compatible with braces, as they sit comfortably over orthodontic brackets without catching on them.
Best Practices for Equipment Integration and Rules Across Sports
A helmet with mouthguard setup is only as good as its fit and integration. Different sports have different equipment designs, rules, and safety standards that athletes must follow.
For example, in American football, the interaction between the helmet’s faceguard and the mouthguard’s tether is critical. A secure connection ensures that if the mouthguard is knocked out of the mouth during a play, it remains attached to the helmet rather than falling onto the dirty turf.
In other sports, like junior A ice hockey, equipment rules are incredibly strict because of the high velocity of pucks and sticks. Research has shown that full faceguards in youth hockey provide a 4.7 times reduction in eye injuries, alongside a non-significant reduction in concussion rates from 12.2 to 2.9 concussions per 1,000 player hours.
Whether you are fitting a football helmet in Phoenix, buying cycling protective gear, or looking for local safety equipment, proper fitting is essential.

How to Properly Fit Your Helmet with Mouthguard
To get the most out of your protective gear, follow these step-by-step fitting guidelines:
- Check the Helmet Fit First: A helmet must sit snugly on the head, about one inch above the eyebrows. It should not slide or shake when you shake your head.
- Secure the Mouthguard Strap: If your mouthguard has a tether, loop it securely around the lower bars of your helmet’s facemask. Make sure it is tight enough that it won’t swing wildly, but loose enough that you can comfortably put the mouthguard in your mouth.
- Verify the Bite: Put the mouthguard in. It should cover all of your upper teeth (and lower teeth if using a double guard) and sit snugly against your palate. You should not have to bite down constantly to keep it in place.
- Practice Breathing and Speaking: Ensure you can speak clearly enough to call out signals and breathe deeply through your mouth.
- Maintain Your Gear: After every game or practice, rinse your mouthguard with cool water and mild soap. Let it air dry completely before placing it in a ventilated case. Never leave it in a hot gear bag or direct Arizona sunlight, as heat can warp the protective shape of both your helmet liner and your mouthguard!
Choosing the Right Helmet with Mouthguard Setup for Youth Sports
For parents, ensuring your child has the right safety setup is a top priority. In youth sports, kids are still growing, and their jaws are constantly changing.
When choosing a helmet with mouthguard combination for a young athlete, look for:
- NOCSAE-certified helmets that are specifically sized for youth players (never buy a larger helmet for a child to “grow into”).
- Re-moldable boil-and-bite mouthguards or custom dental guards that can accommodate erupting adult teeth and orthodontic braces.
- High-visibility colors (like Brian Branch’s green mouthguard) so coaches and referees can easily verify that the player is actually wearing their protective gear on the field.
Frequently Asked Questions about Sports Mouthguards
Why do some football players wear their mouthguard on top of their helmet?
Some players, like Detroit Lions safety Brian Branch, choose to wear their mouthguard on their helmet because they find it difficult to breathe during intense, long defensive drives. Others do it out of habit or personal tradition that started during their high school or college careers. However, from a dental safety standpoint, a mouthguard can only protect your teeth, lips, and jaw when it is actually in your mouth!
Can a mouthguard prevent concussions?
While mouthguards are primarily designed to prevent dental injuries, scientific evidence suggests they can help reduce the severity of concussions caused by lower-jaw impacts. By cushioning the jaw joint and absorbing shock, a mouthguard helps prevent the forces of a chin impact from traveling directly into the base of the skull. However, they do not prevent concussions caused by direct rotational forces to the rest of the head.
How often should an athlete replace their mouthguard?
As a general rule, sports mouthguards should be replaced every season. Over time, the materials degrade, bite pads wear down, and bacteria can accumulate. For growing youth athletes, mouthguards may need to be replaced even more frequently to ensure they continue to fit the changing shape of their mouth and teeth.
Conclusion
At the end of the day, a helmet with mouthguard is the ultimate defensive duo for your head and smile. While players like Brian Branch might make headlines for keeping their mouthguards on their helmets, the safest place for your oral protection is always in your mouth.
