Why Athletes Need a Custom Mouthguard

• Protection: Helps reduce tooth and lip injuries during contact and collisions.
  

• Comfort: A good fit stays in place without clenching.
  

• Performance: Easier breathing and clear calls on the field or court.
  

• Confidence: Players focus on the game—not on fixing their gear.
  
  

Who uses them: football, basketball, lacrosse, hockey, wrestling, rugby, martial arts, and more.

Types of Mouthguards (pick what fits your season and budget)

1) Boil-and-Bite (home custom fit)

• Softens in hot water, then molds to your teeth.
  

• Best for: teams that want good protection fast, with simple at-home fitting.
  

• Pros: affordable, quick, can re-mold 1–2 times.
  

• Consider: follow the steps closely for a snug seal.
  
  

2) Dentist/Lab-Made (impression)

• Made from a dental impression for a very precise fit.
  

• Best for: players who want top precision and keep one guard for a long season.
  

• Pros: excellent retention and comfort.
  

• Consider: higher cost and longer turnaround.
  

3) Stock (no fitting)

• One size off the shelf.
  

• Not recommended for competitive play—poor fit and hard to breathe or talk.
  

AF1 tip: Most teams start with boil-and-bite for cost, speed, and solid protection.

How To Choose the Right Style

Single vs. double

• Single (upper teeth): most common; easier breathing and talking.
  

• Double: extra coverage for heavy contact sports or personal preference.
  

With braces

• Choose a braces-friendly model that can flex around brackets.
  

• Expect to re-fit more often as teeth move.
  

Thickness (simple rule of thumb)

• 3–4 mm: fast sports and skill positions.
  

• 5 mm: heavier contact or players who want a sturdier feel.
  

Strap or no strap (football)

• Strapped guards attach to the facemask so you don’t lose them.
  

• Strapless is fine for other sports.
  

League rules vary. Check color, strap, and logo rules for your school or league.

Step-By-Btep Fit Guide (boil-and-bite)

Follow these steps for a snug, comfortable fit. Have a mirror and timer handy.

1. Heat water until hot, but not boiling. (Boiling can damage the material.)
   

2. Soften: place the mouthguard in hot water for 30–45 seconds (or follow your AF1 insert).
   

3. Cool briefly: remove with tongs, shake off water, and tap for 1–2 seconds to avoid burns.
   

4. Center & seat: align with upper teeth, bite gently, and press the guard up and around teeth and gums.
   

5. Seal: press with fingers on the outside of lips and use tongue to push from behind for 20–30 seconds.
   

6. Set: place in cold water for 30 seconds to lock the shape.
   

7. Test: it should stay in place when you open your mouth. If loose, reheat and re-mold once or twice.
   
   

AF1 inserts include exact times for our models—follow those first.

Fit Checks (takes 30 seconds)

• Retention: open your mouth, the guard should not drop out.
  

• Breathing: you can inhale through your mouth without strain.
  

• Talking: you can call out simple plays without removing it.
  

• Comfort: no sharp edges; trim the tail if it pokes your gums.
  
  

Care & Hygiene

• Rinse after every use (cool water).
  

• Brush gently with a soft brush and mild soap; avoid toothpaste (can scratch).
  

• Air-dry fully; store in a vented case.
  

• No heat: keep away from hot cars or boiling water.
  

• Replace if you see deep bite marks, cracks, heavy odor, or a loose fit—usually each season.
  

Common Mistakes (and quick fixes)

• Water too hot: guard gets floppy → use hot not boiling water.
  

• Biting too hard: creates thin spots → bite light, press with fingers and tongue.
  

• Poor seal: re-mold and press into the gum line for better suction.
  

• Can’t breathe well: choose a single model or a thinner build; trim the back edges.

Frequently Asked Questions (FAQ)

Do I need a custom mouthguard if I don’t play a contact sport?

Yes, if there’s any chance of contact or falls (basketball, soccer, lacrosse, hockey, martial arts). Custom fit stays put without clenching.

Can I re-mold a boil-and-bite?

Usually 1–2 times. Follow the AF1 timing card. If it’s still loose, replace it.

Are there mouthguards for braces?

Yes—choose a braces-friendly model that allows room for brackets and wires. Expect more frequent re-fits.

How often should I replace my mouthguard?

At least once per season, or sooner if you see cracks, deep bite marks, a bad smell, or a loose fit.

Will a thicker guard protect more?

Thicker can feel sturdier, but fit matters most. A well-fitted 3–4 mm can protect better than a loose thick guard.

Can AF1 add our team logo and numbers?

Yes. AthleticForce1 can add a logo and simple numbers; we’ll advise on the quickest printing option.
