Soccer Mouthguard Rules: IFAB Law 4, NFHS and What Leagues Require

Soccer mouthguard rules sit between the Laws of the Game (where a mouthguard is not compulsory) and local league, club and school policies that may still require one. This article focuses on the published rules and equipment guidance. For fit, model picks and how to order, use our soccer mouthguards page.

Always confirm with your league, state association, school or club handbook. Local organizers can make a mouthguard compulsory even when IFAB and NFHS do not.

Is a mouthguard required in soccer?

Under the IFAB Laws of the Game, Law 4 (The Players’ Equipment), a mouthguard is not listed as compulsory equipment. Law 4.2’s compulsory list is a shirt with sleeves, shorts, socks, shinguards and footwear. Law 4.4 permits non-dangerous protective equipment (for example gloves, headgear, facemasks and soft padded protectors). A referee can require a player to remove unauthorized or dangerous equipment under Law 4.1 and Law 4.6.

That is different from U.S. high school sports where the NFHS Sports Medicine Advisory Committee’s Position Statement and Recommendations for Mouthguard Use in Sports (October 2022) says the NFHS mandates mouthguards in football, field hockey, ice hockey, lacrosse, and wrestling (for wrestlers wearing braces). Soccer is not on that NFHS mandate list.

In practice, many clubs, academies and school programs still ask players to wear a mouthguard. Check your competition sheet before kickoff.

IFAB Law 4: permitted, not compulsory

From the current IFAB Law 4 page:

• Law 4.1 Safety — A player must not use equipment or wear anything that is dangerous. The referee can order removal of unauthorized or dangerous equipment or accessories.
• Law 4.2 Compulsory equipment — Shirt, shorts, socks, shinguards and footwear. A mouthguard is not on this list.
• Law 4.4 Other equipment — Non-dangerous protective equipment is permitted.

FIFA competitions follow the IFAB Laws. Do not treat a mouthguard as a FIFA/IFAB mandate for soccer — it is optional kit under Law 4, unless your competition rules add a requirement.

NFHS soccer: not nationally required; new 2026–27 wear guidance

For U.S. high school soccer, NFHS does not nationally require a tooth and mouth protector. Oregon’s OSAA 2026–27 Soccer Plan Book restates Rule 4-2-7 that a tooth and mouth protector is not required.

What is new for 2026–27 is guidance when a player does wear one. NFHS Rule 4-2-7d,e (NEW), documented in the OSAA/NFHS soccer rules changes PDF and on the NFHS soccer rules page, clarifies that tooth and mouth protectors, if worn, should not serve any function other than to protect the teeth or mouth. The published rationale: the protector’s purpose is teeth, mouth and lips (if it has a lip guard); add-ons that do not protect the teeth or mouth should not be allowed, and features that are a health risk to the wearer should not be allowed. An NSGA summary of the same NFHS changes corroborates subsections 4-2-7d and 4-2-7e.

So for high school soccer: not a national “must wear” rule — but if you wear a protector, keep it protective only (no non-protective charms, gadgets or health-risk add-ons).

ADA recommendation (not a soccer law)

The American Dental Association recommends a properly fitted mouthguard for sports with dental trauma risk and lists soccer among common activities where mouthguard use is recommended. That is dental guidance, not a substitute for IFAB Law 4 or your league handbook.

Clubs, academies and youth leagues

AYSO, USSF-affiliated clubs, college conferences and rec leagues can write their own equipment sheets. We do not invent a national “AYSO/USSF requires mouthguards” claim here — if your league handbook requires one, follow it. When in doubt, ask your coach or competition organizer before the season starts.

Color, attachments and referee control

IFAB Law 4 does not set a mouthguard color rule the way some U.S. football codes do for visible tooth-and-mouth protectors. What matters under Law 4 is that the item is non-dangerous and not judged unauthorized by the referee. For NFHS high school soccer in 2026–27, Rule 4-2-7d,e reinforces that any tooth/mouth protector you wear should only protect teeth and mouth — leave non-protective add-ons off the pitch.

Soccer with braces

Athletes with braces can get AlienGuards. Do not use our at-home impression kit over braces; that can damage the appliances. Have your dentist take an impression or 3D scan, then ship it to us or email it to impressions@alienguards.com. More detail in mouthguards for orthodontic patients.

Which AlienGuard for soccer?

Our pick is NanoBite, our 4 mm ultra-slim team-sports guard and the best of our models for breathing and talking through a 90-minute match. NanoBite is built for soccer and other contact team sports (including football, hockey, lacrosse, basketball, wrestling, BJJ, rugby and field hockey).

Origin and Origin Pro are our 5 mm combat guards for boxing, MMA, Muay Thai, kickboxing, karate and taekwondo. They are not our recommendation for soccer. PowerBite is for powerlifting and weightlifting, not team soccer. If you also train striking sports, Origin/Pro are the combat alternatives — not a soccer-team pick.

A custom guard made from your impression stays put better than a loose tray — useful when you are calling for the ball and resetting after contact. If yours already slips, read why does my mouthguard fall out? Start from the soccer mouthguards guide when you are ready to order.

Ordering and club / team orders

Every AlienGuard is made from your own impression. We ship an at-home kit, you take the impression (about 10 minutes), and your custom mouthguard is crafted within 10–14 business days after we receive a good impression, then shipped with tracking. Accessory-only orders (case, kit, putty) ship in a couple of business days.

Teams of 5 or more get 20% off through team orders, including NanoBite and PowerBite, with your logo plus athlete names or numbers. Metallic, satin and holographic text colors are free.

Soccer mouthguard rules FAQ

Is a mouthguard required under IFAB Law 4?

No. Law 4 does not list a mouthguard as compulsory equipment. Non-dangerous protective equipment is permitted, and the referee can require removal of dangerous or unauthorized items. Leagues and clubs may still require a mouthguard.

Does NFHS high school soccer require a mouthguard?

Not nationally. Soccer is not on the NFHS SMAC mandate list. Rule 4-2-7 states a tooth and mouth protector is not required. For 2026–27, Rule 4-2-7d,e adds that if a protector is worn, it should only protect the teeth or mouth.

Does a soccer mouthguard prevent concussions?

Do not choose a mouthguard primarily for concussion prevention. The NFHS SMAC mouthguard statement emphasizes orofacial protection; research does not support relying on a mouthguard to minimize concussion risk or severity.

Can soccer players with braces get AlienGuards?

Yes. Have your dentist take the impression or 3D scan instead of using our at-home kit, then ship it to us or email impressions@alienguards.com.

Which AlienGuard is best for soccer?

NanoBite, our slim 4 mm team-sports guard. Origin and Origin Pro are for combat sports; PowerBite is for lifting, not team soccer.
