Know Thy Mouthguard: What Makes a Customized Mouthguard Truly Protective

Written by Vesna Delic Romero, DDS – Chief Dental Officer, Damage Control Mouthguards

When we think of products built around safety, there are only a few brands that outperform the rest by a wide margin—Volvo being one of the most iconic examples. Their confidence in engineering is so high that they back their vehicles with a Life Event Protection Plan. Just as not all cars perform the same under real-world impact, not all mouthguards deliver the same level of protection—and this is especially true with generic vs customized mouthguards. If you want a clear breakdown of how custom fit vs boil-and-bite mouthguards differ in fit, protection, and performance, we’ve put together a full comparison here.

On Game Day, protection shouldn’t be a guessing game. The properties that make a mouthguard safe should guide the athlete’s choice, not marketing hype or thin retail guards.

Why Material and Thickness Matter

Unlike helmets or pads, there is no standard industry requirement for material type or thickness in mouthguard manufacturing. That means athletes are often left uninformed about what actually protects them best.

In sports, dental injuries occur when the force of impact exceeds the guard’s ability to resist and disperse energy. Up to 90% of these injuries occur in the upper front teeth from direct horizontal blows—exactly the kind of impact most low-cost, thin guards fail to absorb.

This is where the engineering behind customized mouthguards matters.

What the Research Shows

Studies by Tomotaka Takeda et al evaluated impact absorption using EVA (ethylene vinyl acetate) sheets ranging from 1mm to 6mm in thickness. The findings were clear:

• 4mm EVA provided optimal shock absorption without compromising comfort or breathing

• Adding a hard insert layer reduced transmitted impact by up to 70%

• Adding both a hard layer + spacing reduced impact by another 10%

In other words, protection isn’t about “just a mouthguard”—it’s about the right thickness and layered design.

Layering Technology: Why Customization Wins

Additional research shows that layered and pressure-formed customized mouthguards outperform simple molded guards. This method improves:

•  Impact dispersion
•  Force reduction
•  Comfort
•  Breathing and speaking
•  On-field performance

Athletes don’t just need a guard that fits—they need one that performs under stress.

How Damage Control Applies the Science

Damage Control’s customized mouthguards are built using the exact principles confirmed by dental research:

• Scientifically chosen thickness for maximum protection

• Layering techniques that reduce bulk while improving comfort

• Hard-core inserts inspired by proven impact-reduction studies

• Dentist-designed performance standards

These engineering methods set our customized mouthguards apart from mass-produced boil-and-bites and online generics.

Because choosing the wrong mouthguard isn’t just a small mistake—it can lead to lifetime dental issues, psychological hesitation when taking hits, and thousands of dollars in restorative treatment.

Conclusion: Know Thy Mouthguard

Not all mouthguards are built to protect you when it matters most. The science is clear: material, thickness, and layered construction determine whether your teeth are safe or simply covered. At Damage Control, our custom mouthguards are engineered for real-world impact and backed by dental expertise—because Game Day deserves the highest level of protection.

Know thy mouthguard—because protection should be engineered, not assumed.
