Why Custom

Stop fighting
your gear.

Why Fit Matters

A guard that fits
is a guard that works.

A boil-and-bite is a compromise between your teeth and a piece of thermoplastic. A The Grit Lab starts from your mouth and works outward.

Dental-Grade Impression
We capture your bite top and bottom with the same materials your dentist uses — every ridge, every groove.
Molded To Your Exact Bite
Pressure-formed in our lab to the mold of your teeth — not a heated blob that vaguely takes your shape.
No Slipping. No Reshaping.
It locks in the moment you seat it. It stays where you put it, round after round after round.
What A Bad Guard Costs You

Cheap gear
isn't cheap.

A guard that slips, muffles, or reshapes doesn't just fail — it actively works against you. Focus, breath, and teeth all pay the price.

60%
Of athletes report their guard slips or falls out mid-round.
3x
Higher perceived breathing effort with a bulky, ill-fitting guard.
$5K+
Average cost of a single dental injury from unprotected impact.
Sec
The split-second break in focus that costs you the round.
The Bottom Line

You paid to be in the fight. Don't pay again for a guard that quits early.

The The Grit Lab Difference

Every layer has a job.

Nothing about a The Grit Lab guard is generic. Every millimeter is built to protect, breathe, and disappear when you need to focus.
