Under NFHS Field Hockey Rule 1-6 and USA Lacrosse / NFHS Girls Lacrosse Rule 2-9, all players must wear a properly fitted intra-oral tooth and mouth protector of a readily visible color (strictly NOT white or clear). Because girls' lacrosse and field hockey players wear ASTM eye goggles rather than caged helmets, mouthguards must be strapless (no protruding tabs) and cover all upper teeth.
While boys' lacrosse mandates hard-shell helmets with full steel facemasks, girls' lacrosse and high school field hockey athletes take the turf with zero lower-face cage protection. Because solid composite field hockey balls and vulcanized rubber lacrosse balls travel at speeds exceeding 60 to 70 mph, dental and orthodontic protection rules in stick sports are enforced with zero tolerance at pre-game lineup checks.
1. Official NFHS Field Hockey vs. Girls Lacrosse Mouthguard Rule Matrix
Before stepping onto the turf for pre-game stick and goggle inspection, verify your mouthguard against these official NFHS and USA Lacrosse mandates:
| Equipment Spec | NFHS High School Field Hockey (Rule 1-6) | USA Lacrosse & NFHS Girls Lacrosse (Rule 2-9) |
|---|---|---|
| Mandatory Status | 100% Mandatory (All field players & goalies) | 100% Mandatory (All players at all times) |
| Banned Colors | Completely White or Clear Banned | White or Clear Banned (Must be visible color) |
| Protruding Tabs / Straps | Must be worn strapless (unless attached to goalie cage) | Strictly strapless (no protruding front tabs) |
| Chewed / Trimmed Modification | Cannot be chewed through or missing molar coverage | Officials inspect for full occlusal arch coverage |
2. Ball & Stick Impact Physics: Why Single-Layer Guards Fail on Turf
A regulation field hockey ball weighs 5.5 ounces of solid hard plastic, while a lacrosse ball is solid vulcanized rubber. When a deflected pass or high stick check strikes the mouth, single-layer drugstore mouthguards fail in two ways:
- Pinpoint Force Concentrates on Front Incisors: Thin 1-layer rubber compresses immediately upon impact from a rigid stick shaft or ball, transferring kinetic energy straight into your two front teeth and orthodontic brackets.
- How 2X Exoskeleton + 3X Hydro-Mold™ Disperses Shock: Jawgator Armour-Clad™ uses a rigid outer 2X Shock-Dispersing Exoskeleton that spreads ball/stick impact across the entire dental arch, paired with a soft 3X Hydro-Mold™ gel liner that cushions brackets and tooth enamel.
- Convertible 2-in-1 Strapless Design: Pop out the detachable helmet tether in 2 seconds to create a smooth, 100% legal strapless guard for field hockey and girls' lacrosse!
High-Vis Colors + Clear Defensive Slide Calls: Jawgator Armour-Clad™
Pass pre-game referee lineup checks from 20 yards away in High-Vis Neon Pink, Royal Purple, or Stealth Black. Locks to your upper teeth via vacuum suction with a sub-2.4mm zero-gag molar taper so you can shout defensive slides and cutters clearly without touching your guard.
3. Vocal Clarity & Braces Protection During Full-Field Sprints
Both field hockey and girls' lacrosse demand non-stop midfield transition running and constant defensive communication ("Got ball!", "Slide left!", "Cutter middle!"):
- Stop the "Chewing on the Corner" Habit: When a bulky drugstore mouthguard triggers the gag reflex, midfielders pull it halfway out of their mouth and chew on the corner while running—which triggers an immediate referee whistle and green/yellow card warning.
- Vacuum Suction Fit + 3X Braces Remoldability: Jawgator's sub-2.4mm rear molar taper clears the soft palate completely, and its 3X Hydro-Mold™ gel liner can be re-boiled up to 3 times as orthodontic braces or Invisalign attachments shift your teeth.
4. Frequently Asked Questions (Field Hockey & Girls Lacrosse Rules)
Why are white and clear mouthguards illegal in field hockey and lacrosse?
Under NFHS Field Hockey Rule 1-6 and USA Lacrosse rules, white and clear mouthguards are prohibited because officials cannot distinguish them from bare teeth across the field during live play. High-contrast colors like Neon Pink, Royal Purple, and Stealth Black are 100% legal.
Can field hockey and lacrosse players wear a mouthguard with braces?
Yes. Athletes with braces should wear a dual-layer mouthguard like the Jawgator Armour-Clad™, which molds over brackets in 28–32 seconds without sticking and shields the inner lips from lacerations during stick checks.
Are mouthguards with straps allowed in girls' lacrosse?
Because field players in girls' lacrosse wear ASTM eye goggles rather than caged helmets, dangling tether straps must be removed. Simply detach the removable strap on your Jawgator guard for 100% strapless compliance.
Jawgator Armour-Clad™ 2-Pack Combat Duo
