Which Sports Require a Mouthguard?
A mouthguard is the cheapest dental insurance in all of youth sports. It cushions blows to the jaw, protects the teeth from direct impact, and — by absorbing and redistributing force — can reduce the severity of concussions caused by lower-jaw impacts. The rules on when one is required, however, vary by sport.
| Sport | Mouthguard Requirement | Notes |
|---|---|---|
| Football (tackle & flag) | Mandatory at every level | All youth football players must wear one. Many leagues require a visible color (not clear or white) so officials can verify compliance at a glance. |
| Soccer | Optional (not required by the Laws of the Game) | Recommended for goalkeepers and defenders who challenge in the air; not commonly worn by field players. |
| Volleyball | Optional | Rarely worn; occasionally used by players with braces or prior dental work. |
| Hockey, lacrosse, rugby, wrestling, martial arts, basketball | Mandatory in most sanctioned leagues | Any contact or collision sport carries enough dental-injury risk to warrant a guard, mandatory or not. |
The visible-color rule in football
Many youth football leagues mandate mouthguards in a visible color — not clear or white — precisely so a referee standing yards away can confirm a player is wearing one. If your child plays football, buy a colored guard and have a backup; a missing or clear mouthguard is one of the most common reasons a player is held out of a play or game until it's fixed.
Dental Injury Statistics
Sports-related dental injuries are common, expensive, and largely preventable. The numbers make the case for a $10–$30 mouthguard unambiguous:
- An estimated 10–39% of all dental injuries in children are sports-related, with the highest rates in contact and collision sports.
- A single knocked-out permanent tooth can cost $1,500–$5,000+ over a lifetime to treat (implant, root canal, crown, ongoing care) — far more than even a custom-fitted mouthguard.
- Properly fitted mouthguards reduce the risk of dental injury by a wide margin; the American Dental Association recommends them for any sport with a risk of contact or falls.
The Three Types of Mouthguard
Mouthguards fall into three categories, ranging from a few dollars to a few hundred. The protection gap between them is real, but so is the convenience gap.
| Type | How It Works | Cost | Protection Level | Best For |
|---|---|---|---|---|
| Stock | Pre-formed, worn as-is out of the package; no molding | $3–$8 | ★☆☆☆☆ (worst fit) | Emergencies only; the bare minimum. Bulky, loose, hard to breathe or talk with. |
| Boil-and-bite | Softened in boiling water, then bitten to mold to the teeth | $5–$30 | ★★★☆☆ | The most common choice for youth; good fit when molded correctly, affordable, easy to replace. |
| Custom-fitted (dentist-made) | Vacuum- or pressure-formed from a dental impression for an exact fit | $200–$500 | ★★★★★ (best protection) | Maximum protection and comfort; competitive athletes, players with braces, and anyone who can afford it. |
High-performance boil-and-bite is the value sweet spot
A growing category sits between standard boil-and-bite and custom: high-performance boil-and-bite guards ($15–$35) use advanced dual-layer polymers that mold more precisely than basic models and come far closer to custom fit. For most competitive youth players, this is the best balance of protection, comfort, and cost — brands like SISU and Shock Doctor lead this tier.

How to Properly Fit a Boil-and-Bite Mouthguard
A boil-and-bite guard only protects as well as it fits, and most fit poorly because they are molded in a hurry. Follow these steps carefully — and redo it if the fit isn't snug.
- Boil water in a small pot or microwave, then pour it into a mug or bowl. You need enough to fully submerge the guard.
- Submerge the mouthguard for the time stated on the package (usually 30–60 seconds) — long enough to soften but not so long that it loses its shape entirely.
- Remove and shake off the hot water. Run under cold tap water for 1–2 seconds so it is warm, not scalding, then test against the lip first.
- Bite down firmly on the guard, centered over the upper teeth, and use your fingers and tongue to press the softened material up against the teeth and gums. Suck in sharply to pull the material tight against the teeth.
- Hold the bite for 30–45 seconds while the material sets and takes the exact shape of the teeth.
- Remove and rinse in cold water to lock the shape in place.
- Test the fit. The guard should snap onto the upper teeth and stay in place on its own when you open your mouth — if it falls out, re-boil and re-mold.
When to Replace
Mouthguards wear out, and a worn guard offers less protection. Replace when:
- Each season for active players — the material compresses and loses its precise fit over months of use.
- Chewed through. Many kids chew their guards during games and practice; once there are deep tooth marks or thin spots, the guard no longer cushions evenly.
- Growth. A child's mouth changes rapidly — a guard molded at age 10 will not fit at 12. Re-mold or replace whenever the fit loosens.
- Braces change. Players with braces need a guard re-molded (or a new orthodontic guard) whenever brackets are adjusted or removed.
- Visible damage — tears, holes, or distortion.
Insurance & Budget Considerations
- Dental insurance may cover custom guards. Many dental plans cover part or all of a custom-fitted mouthguard from a dentist, especially for kids in contact sports. It's worth a call before paying out of pocket.
- Always carry a backup. Mouthguards are the most lost piece of equipment in youth sports. Keep a spare in the bag — a $10 boil-and-bite backup saves a game-day disaster.
- Never sacrifice safety for savings on guards. A $5 boil-and-bite from a reputable brand is acceptable; a $2 novelty guard from a dollar store is not. Spend enough to get certified, BPA-free material.
- Braces need orthodontic guards. Players with braces require a guard designed to protect both the teeth and the brackets — standard guards can jam brackets into the lips on impact. Brands like Shock Doctor make specific orthodontic models.
Budget Recommendations
- First-year / recreational ($5–$15): A basic Shock Doctor or Nike boil-and-bite is perfectly adequate. Buy two.
- Competitive youth ($15–$30): Step up to SISU NextGen or Shock Doctor Gel Max for better fit and protection.
- Serious / multiple-sport athletes ($200–$500): A custom-fitted guard from a dentist offers the best protection and comfort, and often lasts longer because it doesn't get chewed out of frustration with a poor fit.
