What thickness for Muay Thai or kickboxing?

Heavy 4mm — same maximum-protection platform as our boxing guard.

Is this the same as the boxing guard?

Same 4mm platform, custom-molded to you — pick the page that matches your sport for sizing guidance.

Can I breathe in the clinch?

Yes — precision cuts keep airways open even under load.

Can I use it with braces?

Yes — via a dentist digital scan (putty impression kits can stick to and damage brackets; re-scan every 4-6 months as teeth move). After braces, one scan covers custom products for life — see our Braces page.

Do NHL players wear custom-fit mouthguards?

Yes — TRUFIT is worn by many players across the NHL. We proudly serve most NHL teams. Custom-fit guards stay in place all game long.

What's the difference between a custom-fit mouthguard and a boil-and-bite?

Boil-and-bite guards shift during play and block airflow. A TRUFIT guard is made from your exact impression — it fits precisely, stays put, and is trimmed so it never blocks your airway.

How does the at-home impression process work?

We ship you an impression kit, you mold it at home and mail it back, and your custom guard is delivered to your door — no dentist visit required.

Do TRUFIT sports mouthguards prevent concussions?

No appliance can prevent concussions, but research shows that sports mouthguards may reduce severity and the occurrence of concussions.

How long does a custom MMA mouthguard last?

Most players get 1–2 seasons per guard with no chewing and proper care and maintenance. Your impression stays on file so reorders are fast.

Breathe Heavy. Stay Anchored.

Striking arts deliver impact from angles a boxing guard never sees —elbows in the clinch, head kicks, flying knees. Our Heavy 4mm combat build spreads that impact across your whole arch.

Clinch work means mouth-breathing under load; a custom guard stays anchored where boil-and-bite floats loose.
