Football Mouthguard Rules: NFHS, NCAA and Clear Guards

Football is one of the sports where a mouthguard is not optional at the high school and college levels. Parents, players and coaches still ask the same things every season: is a clear mouthguard legal, what does NFHS actually require, and does college football still ban white or transparent guards? This article walks through what the published rules say, where youth leagues differ, and how to pick a guard that stays in through a game. For fit, model picks and team ordering, start with our football mouthguard guide.

Rules change, and your state association or conference can publish its own interpretations. Always check the current rulebook and your league's equipment sheet before kickoff.

Is a mouthguard required in football?

Yes at the high school and college levels that follow NFHS or NCAA football rules. The American Dental Association states that the NFHS and the NCAA mandate mouthguards in football (along with field hockey, ice hockey and lacrosse; NFHS also requires them for wrestlers wearing braces).

The NFHS Sports Medicine Advisory Committee's Position Statement and Recommendations for Mouthguard Use in Sports (October 2022) likewise lists football among the sports where the NFHS mandates mouthguard use. It recommends a properly fitted, unaltered mouthguard that separates the biting surfaces, protects the lips, gums and teeth, and fully covers the upper teeth (or the lower teeth if those are the leading edge).

Youth and recreational leagues write their own equipment rules. Many require a mouthguard; some do not. Check your league handbook rather than assuming high school rules apply.

NFHS high school football: what changed in 2016

For years, high school football officials looked for a colored mouthguard because clear or white ones blended in with teeth. That changed in 2016. The NFHS football rules change for Rule 1-5-1d(5)a clarified the tooth and mouth protector specs and stated that completely clear or completely white tooth and mouth protectors are no longer prohibited. The same change notes that a tooth and mouth protector must include an occlusal portion (protecting and separating the biting surfaces) and a labial portion (protecting the teeth and supporting structures). Mouthguards that have been chewed or altered so they no longer provide the necessary protection must be replaced. Source: NFHS Football Rules Changes — 2016.

So for NFHS football today, a clear or white guard can be legal if it still covers and protects as required. Decorative attachments that do not protect the teeth are a separate issue; follow your state association's current equipment list.

NCAA college football: still no white or transparent

College football is stricter on color. In the current NCAA Football Rules Book, a mouthpiece is listed as mandatory equipment for every player. The specifications say the mouthpiece must be an intra-oral device of any readily visible color, must not be white or transparent, must be made with FDA-approved base materials, and must cover all upper teeth. It is recommended that the mouthpiece be properly fitted. Source: NCAA Football Rules Book (Rule 1, mandatory equipment / mouthpiece specifications).

If a player is obviously not wearing a mouthpiece, the NCAA rules treat it as an equipment issue: the player must leave the game for at least one down and may not return until properly equipped (a team timeout can keep them in the game, but they still may not play until the mouthpiece is on).

That means a clear NanoBite that is fine under current NFHS football rules may still fail a college equipment check. If you play both levels, or you expect to move up, pick a readily visible color for college.

Youth vs high school vs college at a glance

• Youth / rec: league-specific. Confirm before you order.
• High school (NFHS): mouthguard required; clear and white allowed since the 2016 clarification; must still protect and cover as required; replace chewed or altered guards.
• College (NCAA): mouthguard required; readily visible color; not white or transparent; covers all upper teeth.

Coaches and officials: if you are not sure whether a guard meets the rule, ask your state interpreter or conference coordinator rather than guessing from an old clinic slide. Color rules in particular have changed.

Football 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 can you wear a mouthguard with braces?

A stock or poorly fitted boil-and-bite guard is a poor match for braces. The ADA describes stock mouthguards as the least effective type because of generic shape and poor retention, and notes that dental professionals may help with molding when orthodontic appliances are involved.

Which AlienGuard for football?

Our pick is NanoBite, our 4 mm team-sports guard. It is the best of our models for breathing and talking, so players can call signals and breathe between plays. NanoBite is built for football and other contact team sports (including hockey, lacrosse, basketball, wrestling, BJJ, rugby, soccer 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 football.

A custom guard made from your impression stays put better than a loose tray, which matters when officials are watching for a missing mouthpiece and when you need to talk with the guard in. If yours already slips, read why does my mouthguard fall out?

Ordering ahead of the season

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, with your logo plus athlete names or numbers. Metallic, satin and holographic text colors are free.

Football mouthguard rules FAQ

Is a mouthguard required in high school football?

Yes under NFHS football rules. The ADA and the NFHS mouthguard position statement both list football among the sports where a mouthguard is mandated. Confirm any state-association notes with your athletic director.

Can you wear a clear mouthguard in football?

In NFHS high school football, yes: the 2016 rules change stopped prohibiting completely clear or completely white tooth and mouth protectors. In NCAA college football, no: the mouthpiece must be a readily visible color and must not be white or transparent.

What if my mouthguard is chewed up?

The NFHS 2016 clarification says a tooth and mouth protector that has been chewed or altered so it no longer provides the necessary protection must be replaced. Do not cut a guard down to front teeth only.

Can football 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 football?

NanoBite, our slim 4 mm team-sports guard. Origin and Origin Pro are for combat sports, not football.
