Can Kids Use Night Guards? A Parent’s Guide to Bruxism in Children

Hearing your child grind their teeth at night can be alarming—but is a night guard the right solution? While bruxism (teeth grinding) is common in children, the decision to use a night guard depends on their age, dental health, and severity of grinding.

This parent’s guide covers:
✔ Why kids grind their teeth
✔ When a night guard is necessary
✔ Child-safe alternatives
✔ How to choose the right option

Why Do Children Grind Their Teeth?

Common causes include:

• New teeth coming in (discomfort leads to grinding)

• Misaligned bite (upper and lower teeth don’t fit properly)

• Stress or anxiety (school pressure, changes at home)

• Sleep disorders (like sleep apnea)

• Hyperactivity or caffeine (soda, chocolate before bed)

💡 Up to 30% of children grind their teeth, but most outgrow it by adolescence.

When Does a Child Need a Night Guard?

Consult a pediatric dentist if your child:

• Grinds loudly (you can hear it at night)

• Complains of jaw pain or headaches

• Has worn-down, chipped, or sensitive teeth

• Is losing baby teeth prematurely from grinding

🚫 Avoid OTC adult guards—they can interfere with jaw development in kids.

Night Guard Options for Kids

1. Custom Pediatric Night Guards

• Pros:

  • Made from soft, flexible materials

  • Fits comfortably over baby or mixed teeth

  • Prevents damage to permanent teeth

• Cons:

  • Needs replacement as teeth grow

  • More expensive (~$200-$400)

2. Boil-and-Bite (Modified for Kids)

• Pros:

  • Affordable (~$30-$60)

  • Can be trimmed for smaller mouths

• Cons:

  • Less durable (lasts ~3-6 months)

  • May feel bulky

3. Dental Splints (For Severe Cases)

• Prescribed by a dentist for TMJ issues

• Helps guide jaw growth

💡 Best choice? A dentist-approved custom guard—especially if permanent teeth are coming in.

Alternatives to Night Guards for Kids

For mild cases, try:
✅ Warm compress before bed (relaxes jaw muscles)
✅ Hydration (dehydration can worsen grinding)
✅ Stress-reducing bedtime routine (reading, calming music)
✅ Cutting caffeine (no soda/chocolate after lunch)

What to Avoid

❌ Adult night guards (too big, risk of choking)
❌ Ignoring severe grinding (can damage permanent teeth)
❌ DIY fixes (like mouthguards for sports—not designed for grinding)

Final Verdict: Should Your Child Use One?

When in doubt, ask your pediatric dentist!
